1 00:00:06,160 --> 00:00:09,799 Speaker 1: Hello, and welcome to Stuff to Blow Your Mind. It's Saturday, 2 00:00:09,880 --> 00:00:11,840 Speaker 1: so we are heading into the vault for an older 3 00:00:11,880 --> 00:00:14,840 Speaker 1: episode of the podcast. This is part three of the 4 00:00:14,880 --> 00:00:18,200 Speaker 1: series that Rob and I did on the Ninja. This 5 00:00:18,280 --> 00:00:21,480 Speaker 1: originally published August first, twenty twenty four. 6 00:00:25,040 --> 00:00:28,760 Speaker 2: Welcome to Stuff to Blow Your Mind, production of iHeartRadio. 7 00:00:34,760 --> 00:00:37,159 Speaker 3: Hey, welcome to Stuff to Blow Your Mind. My name 8 00:00:37,240 --> 00:00:37,839 Speaker 3: is Robert. 9 00:00:37,680 --> 00:00:40,600 Speaker 1: Lamb and I'm Joe McCormick, and we're back with part 10 00:00:40,680 --> 00:00:44,680 Speaker 1: three in our series on Ninja. Now, if you haven't 11 00:00:44,680 --> 00:00:47,280 Speaker 1: heard the first two parts of this series, this is 12 00:00:47,320 --> 00:00:49,680 Speaker 1: a case where you really should go back and listen 13 00:00:49,720 --> 00:00:52,120 Speaker 1: to those before you listen to today's episode, because we 14 00:00:52,200 --> 00:00:56,680 Speaker 1: lay a lot of groundwork, especially about the tricky historical 15 00:00:56,800 --> 00:01:01,240 Speaker 1: questions about the sort of act curacy of a lot 16 00:01:01,280 --> 00:01:04,720 Speaker 1: of the received knowledge about the Ninja. And so if 17 00:01:04,760 --> 00:01:07,720 Speaker 1: you are wondering about like how the Ninja fit into 18 00:01:07,840 --> 00:01:12,440 Speaker 1: real history versus pop culture and then sort of subsequent 19 00:01:12,840 --> 00:01:15,760 Speaker 1: lore and legend, we talk more about that in the 20 00:01:15,760 --> 00:01:18,880 Speaker 1: previous episodes. Today we're going to be focusing more on 21 00:01:19,120 --> 00:01:22,679 Speaker 1: just some of the great bits of texture and the 22 00:01:22,760 --> 00:01:26,600 Speaker 1: anecdotes from that historical law and legend. The stories of 23 00:01:26,680 --> 00:01:31,240 Speaker 1: individual ninjas, the stories of the stories of tools and 24 00:01:31,319 --> 00:01:33,440 Speaker 1: techniques and equipment and so forth. 25 00:01:33,959 --> 00:01:36,360 Speaker 3: Yeah, I mean, you basically can think of it this way. 26 00:01:37,120 --> 00:01:41,399 Speaker 3: The ninja existed, true statement, the ninja are a myth 27 00:01:41,400 --> 00:01:44,320 Speaker 3: and never existed true statement depends on how you tease 28 00:01:44,360 --> 00:01:47,240 Speaker 3: it apart, you know. And likewise a lot of this too, 29 00:01:47,280 --> 00:01:51,320 Speaker 3: Like we'll get into specific examples of ninja tools or weapons, 30 00:01:51,320 --> 00:01:54,080 Speaker 3: and you can say this never existed, and then you 31 00:01:54,080 --> 00:01:56,640 Speaker 3: can also say, but I can buy one at the 32 00:01:56,680 --> 00:02:00,160 Speaker 3: mall today, and so it's like, well it exists now, right, 33 00:02:00,200 --> 00:02:01,920 Speaker 3: So it gets complicated. 34 00:02:02,440 --> 00:02:04,800 Speaker 1: This is a great time, I think to discuss some 35 00:02:04,920 --> 00:02:09,000 Speaker 1: of the various ninjutsu manuals that were published beginning in 36 00:02:09,040 --> 00:02:14,560 Speaker 1: the Edo period beginning under the Tokugawa Shogunate, that are 37 00:02:14,600 --> 00:02:18,320 Speaker 1: the source of a lot of the ninja lore that 38 00:02:18,360 --> 00:02:20,320 Speaker 1: we have today. So you can think about sort of 39 00:02:20,400 --> 00:02:24,480 Speaker 1: like multiple stages of development of the ninja lore over 40 00:02:24,520 --> 00:02:29,160 Speaker 1: the centuries. This is going way back. It's questionable whether 41 00:02:29,280 --> 00:02:32,440 Speaker 1: some of the things reported in these manuals were actually 42 00:02:32,600 --> 00:02:36,680 Speaker 1: used in the earlier periods. But these, you know, seventeenth 43 00:02:36,760 --> 00:02:40,799 Speaker 1: eighteenth century texts have lots of great stuff in them 44 00:02:40,840 --> 00:02:44,639 Speaker 1: that I think later gets picked up by authors, say 45 00:02:44,680 --> 00:02:48,960 Speaker 1: in the twentieth century, and reprocessed and turned into the 46 00:02:49,000 --> 00:02:52,320 Speaker 1: pop culture idea of the ninja. So there are multiple 47 00:02:52,480 --> 00:02:56,760 Speaker 1: ninjitsu manuals, and I'm just going to list some common 48 00:02:56,880 --> 00:03:03,240 Speaker 1: characteristics of them. So they will teach techniques of espionage, stealth, 49 00:03:03,280 --> 00:03:07,400 Speaker 1: and intelligence gathering, including everything from how to infiltrate a 50 00:03:07,400 --> 00:03:11,000 Speaker 1: building using different kinds of ladders to how to gag 51 00:03:11,040 --> 00:03:15,239 Speaker 1: a prisoner. So they're full of descriptions of techniques. They 52 00:03:15,280 --> 00:03:19,560 Speaker 1: pass along practical knowledge about real subjects, such as pharmacology, 53 00:03:19,680 --> 00:03:22,120 Speaker 1: like using herbs to achieve an effect in the body, 54 00:03:22,639 --> 00:03:25,920 Speaker 1: and how to use gunpowders. So there is some amount 55 00:03:25,960 --> 00:03:28,600 Speaker 1: of chemistry knowledge, at least as it was understood in 56 00:03:28,639 --> 00:03:32,239 Speaker 1: the seventeenth century. In some of these books, they describe 57 00:03:32,240 --> 00:03:36,480 Speaker 1: and illustrate tools and equipment such as caltrops. You know, 58 00:03:36,520 --> 00:03:40,600 Speaker 1: these spiked spiked objects that would be used. You know, 59 00:03:40,640 --> 00:03:42,960 Speaker 1: you'd throw them on the ground to slow the advance 60 00:03:42,960 --> 00:03:45,400 Speaker 1: of an enemy or to deny them access to an area. 61 00:03:45,680 --> 00:03:48,720 Speaker 3: Yeah, makabishi, I believe is the term for these. And 62 00:03:49,520 --> 00:03:52,560 Speaker 3: these are interesting on their own terms because if you've 63 00:03:52,560 --> 00:03:54,600 Speaker 3: played Dungeons and Dragons. You may have used these, you know, 64 00:03:54,600 --> 00:03:57,520 Speaker 3: these are pretty common way to slow down an enemy, 65 00:03:58,800 --> 00:04:02,200 Speaker 3: but a pair when you get into the history of 66 00:04:02,240 --> 00:04:06,800 Speaker 3: their use in Shinobi activities, like some examples of them 67 00:04:06,800 --> 00:04:10,480 Speaker 3: may have been essentially organic or found items, like essentially 68 00:04:10,520 --> 00:04:14,240 Speaker 3: like throwing nuts or you know, or today's version would 69 00:04:14,240 --> 00:04:17,279 Speaker 3: be like spreading legos all over the floor. That's not 70 00:04:17,360 --> 00:04:19,560 Speaker 3: quite like a nature fact or a found item, but 71 00:04:19,600 --> 00:04:21,280 Speaker 3: you know, you get the idea, and then you could 72 00:04:21,320 --> 00:04:25,040 Speaker 3: progress from there into potentially like metal objects that are 73 00:04:25,080 --> 00:04:28,240 Speaker 3: spiked and so forth. And speaking of those ladders, yes, 74 00:04:28,440 --> 00:04:31,560 Speaker 3: ladders are absolutely a tool of the ninja. And if 75 00:04:31,600 --> 00:04:33,720 Speaker 3: you are in the Dungeons and Dragons campaign and you're 76 00:04:33,720 --> 00:04:36,520 Speaker 3: playing a rogue, go ahead and equip that ladder, bring 77 00:04:36,560 --> 00:04:38,960 Speaker 3: that ladder with you, and dare your dungeon master to 78 00:04:39,000 --> 00:04:42,160 Speaker 3: make you roll a dexterity check whilst climbing it. Ladders 79 00:04:42,160 --> 00:04:44,120 Speaker 3: are great. Trust the ninja on this. 80 00:04:45,160 --> 00:04:47,880 Speaker 1: My current rogue has a real affinity for climbing. He's 81 00:04:47,880 --> 00:04:50,240 Speaker 1: got the I don't know his level three or level 82 00:04:50,240 --> 00:04:51,880 Speaker 1: four or wherever it is. You get to pick one 83 00:04:51,920 --> 00:04:54,520 Speaker 1: of the feats, and he's got second story work where 84 00:04:54,560 --> 00:04:56,360 Speaker 1: you know, you can climb at the same rate you 85 00:04:56,440 --> 00:04:57,320 Speaker 1: can you can run. 86 00:04:57,600 --> 00:04:59,960 Speaker 3: That's great. Yeah, but I feel like we've been kind 87 00:04:59,960 --> 00:05:03,919 Speaker 3: of it's like a modern Ninja batmanification of our understanding 88 00:05:03,960 --> 00:05:06,839 Speaker 3: of what rogues should have because Batman never carried a ladder, 89 00:05:06,839 --> 00:05:08,400 Speaker 3: but he probably should have carried a ladder. I think 90 00:05:08,440 --> 00:05:08,960 Speaker 3: that would be great. 91 00:05:08,960 --> 00:05:11,640 Speaker 1: The bat ladder, I mean, the rope ladder will get 92 00:05:11,680 --> 00:05:13,440 Speaker 1: you a lot of places. I guess Batman doesn't need 93 00:05:13,440 --> 00:05:16,480 Speaker 1: a ladder because he has the unrealistic the batclaw thing 94 00:05:16,560 --> 00:05:18,919 Speaker 1: that you can just shoot and will zip him up anywhere. 95 00:05:19,240 --> 00:05:24,560 Speaker 3: Absolute trust in the masonry the building that he's interacting with. Yeah. 96 00:05:24,640 --> 00:05:28,159 Speaker 1: But anyway, all the stuff I've mentioned so far, that's 97 00:05:28,200 --> 00:05:31,480 Speaker 1: the stuff you would imagine a ninjitsu manual to include, right, 98 00:05:31,560 --> 00:05:36,880 Speaker 1: you know, techniques about stealth tools. You could use, knowledge 99 00:05:36,920 --> 00:05:40,440 Speaker 1: about pharmacology and gunpowder and things like that, but there 100 00:05:40,440 --> 00:05:44,560 Speaker 1: are also things you might expect less. These manuals often 101 00:05:44,720 --> 00:05:49,599 Speaker 1: emphasize spiritual and philosophical elements of the Shinobi lifestyle, like 102 00:05:49,839 --> 00:05:53,080 Speaker 1: some during the Edo period promote Confucianism with a strong 103 00:05:53,160 --> 00:05:56,000 Speaker 1: emphasis on loyalty, which of course was favored by the 104 00:05:56,320 --> 00:06:02,080 Speaker 1: Tokugawa shoguns. They sometimes also include moral discourses that serve 105 00:06:02,200 --> 00:06:06,680 Speaker 1: as justification for shnobi activities, like it's okay to use 106 00:06:06,800 --> 00:06:10,400 Speaker 1: lies and deception and trickery because they will help you win. 107 00:06:10,560 --> 00:06:12,640 Speaker 1: They're what you have to do to win, and what's 108 00:06:12,720 --> 00:06:15,880 Speaker 1: ultimately right is to be loyal to your masters and 109 00:06:15,920 --> 00:06:19,880 Speaker 1: to help win in the conflict. And so so you know, 110 00:06:19,920 --> 00:06:22,280 Speaker 1: you got to deliver that intelligence. It doesn't matter if 111 00:06:22,279 --> 00:06:24,920 Speaker 1: you have to lie to do it. They sometimes also 112 00:06:24,960 --> 00:06:29,839 Speaker 1: include more esoteric guidance, like the use of astrology or divination. 113 00:06:31,400 --> 00:06:35,159 Speaker 1: They are often falsely attributed to a great hero or 114 00:06:35,279 --> 00:06:40,159 Speaker 1: legend from history. They do not depict shnobi in black 115 00:06:40,200 --> 00:06:45,359 Speaker 1: costumes and masks. They are not generally concerned with assassination, 116 00:06:45,839 --> 00:06:49,400 Speaker 1: nor do they usually describe hand to hand combat or 117 00:06:49,440 --> 00:06:52,279 Speaker 1: sword fighting techniques, as would come to be the calling 118 00:06:52,360 --> 00:06:56,400 Speaker 1: card of ninja in later movies. Once again, they are 119 00:06:56,640 --> 00:07:02,000 Speaker 1: most often concerned with intelligence gathering, cycle, logical warfare, and sabotage. 120 00:07:02,480 --> 00:07:04,400 Speaker 1: And to this point, one of the manuals I'll mention 121 00:07:04,560 --> 00:07:07,880 Speaker 1: in a minute actually specifies that your shnobi your spies 122 00:07:08,000 --> 00:07:12,600 Speaker 1: should be selected based on intelligence and not physical strength 123 00:07:13,040 --> 00:07:16,880 Speaker 1: because these people were not primarily thought of as fighters, 124 00:07:17,000 --> 00:07:20,520 Speaker 1: but as tricksters and observers, gatherers of information. 125 00:07:21,160 --> 00:07:24,800 Speaker 3: Yeah. I mean, when you think about it, like your shnobi, 126 00:07:24,920 --> 00:07:26,640 Speaker 3: are they going to be able to throw down with 127 00:07:26,720 --> 00:07:30,440 Speaker 3: the samurai of an arms samurai, like you know, one 128 00:07:30,480 --> 00:07:33,600 Speaker 3: to one in some sort of a battle. I think 129 00:07:33,600 --> 00:07:36,640 Speaker 3: there's a strong case to be made. No, the trickery 130 00:07:36,720 --> 00:07:40,119 Speaker 3: if that, if that's sort of violent encounter were to occur, 131 00:07:40,400 --> 00:07:43,040 Speaker 3: the trickery is going to make the difference, not the 132 00:07:43,400 --> 00:07:44,080 Speaker 3: martial arts. 133 00:07:44,080 --> 00:07:46,240 Speaker 1: I'm guessing that's right. As we talked about in the 134 00:07:46,320 --> 00:07:50,080 Speaker 1: last episode, the idea of shnobi as instigators of daring 135 00:07:50,320 --> 00:07:54,400 Speaker 1: individual violence and hand to hand combat, that is more 136 00:07:54,600 --> 00:07:58,120 Speaker 1: of the later movie ninja thing. The earlier emphasis is 137 00:07:58,320 --> 00:08:00,520 Speaker 1: though there all there are lots of sort of shinobi 138 00:08:00,920 --> 00:08:05,160 Speaker 1: warfare activities in shinobi attacks, sneak attacks by night. Most 139 00:08:05,160 --> 00:08:08,480 Speaker 1: of the time, these manuals and early ideas of shinobi 140 00:08:08,840 --> 00:08:13,160 Speaker 1: are more focused on spying. For just one example of 141 00:08:13,400 --> 00:08:17,320 Speaker 1: how these older military manuals might focus more on espionage 142 00:08:17,320 --> 00:08:22,120 Speaker 1: strategy than on the type of combat focused ninja behavior 143 00:08:22,160 --> 00:08:25,800 Speaker 1: we think of today, there was a sixteenth century military 144 00:08:25,840 --> 00:08:30,800 Speaker 1: manual called the Kinetsushu, and this text was from earlier 145 00:08:30,840 --> 00:08:33,240 Speaker 1: than the major ninjutsu manual, So this is not I 146 00:08:33,320 --> 00:08:34,599 Speaker 1: want to be clear, this is not one of the 147 00:08:34,679 --> 00:08:38,120 Speaker 1: ninjutsu manuals I'm talking about. This is a general warfare 148 00:08:38,200 --> 00:08:41,240 Speaker 1: manual from a little bit earlier, and its focus is 149 00:08:41,280 --> 00:08:46,119 Speaker 1: broadly on strategy and warfare, but it contains a subsection 150 00:08:46,360 --> 00:08:50,240 Speaker 1: on espionage techniques, and it recommends things like the following. 151 00:08:50,280 --> 00:08:53,240 Speaker 1: It says, before you go on a military campaign, send 152 00:08:53,360 --> 00:08:57,400 Speaker 1: spies into the area that you're targeting to pose as 153 00:08:57,520 --> 00:09:01,880 Speaker 1: merchants and craftsmen. And these spies should make maps of 154 00:09:01,960 --> 00:09:05,959 Speaker 1: local topography and try to figure out the morale of locals, 155 00:09:05,960 --> 00:09:09,120 Speaker 1: for example by listening to whether people sing sad songs 156 00:09:09,200 --> 00:09:12,400 Speaker 1: or happy songs. And you can also try to split 157 00:09:12,559 --> 00:09:16,040 Speaker 1: loyalties within the region by doing things like have your 158 00:09:16,120 --> 00:09:19,920 Speaker 1: spies make donations to local temples and shrines to win 159 00:09:19,960 --> 00:09:22,120 Speaker 1: over the approval of the priest class. 160 00:09:22,480 --> 00:09:24,520 Speaker 3: And I'm guessing you had to be kind of selective 161 00:09:24,520 --> 00:09:26,720 Speaker 3: about how you do it, Like don't immediately set up 162 00:09:26,760 --> 00:09:28,800 Speaker 3: shop and be like, hey, what do you think of 163 00:09:28,800 --> 00:09:33,040 Speaker 3: the latest Lena Delray album? You know, like tease it 164 00:09:33,080 --> 00:09:35,000 Speaker 3: out a little bit. Make sure you have enough lead 165 00:09:35,080 --> 00:09:40,000 Speaker 3: time to really immerse yourself in the local community. 166 00:09:40,400 --> 00:09:42,520 Speaker 1: Exactly right. Oh, and I should say, by the way, 167 00:09:42,559 --> 00:09:44,360 Speaker 1: I mentioned it in the last couple of episodes, but 168 00:09:44,480 --> 00:09:46,560 Speaker 1: just to flag again one of my major sources here 169 00:09:47,040 --> 00:09:50,520 Speaker 1: also on the general facts about these ninja two manuals 170 00:09:51,080 --> 00:09:54,400 Speaker 1: is a book by a British historian named Stephen Turnbull 171 00:09:54,480 --> 00:09:58,199 Speaker 1: called Ninja Unmasking the Myth from twenty seventeen, and so 172 00:09:58,280 --> 00:10:02,360 Speaker 1: he highlights several important ninjitsu manuals that I wanted to 173 00:10:02,440 --> 00:10:05,599 Speaker 1: talk about for a moment here. These later manuals in 174 00:10:05,640 --> 00:10:10,120 Speaker 1: the seventeenth century onward were more directly focused on ninjitsu, 175 00:10:10,320 --> 00:10:14,920 Speaker 1: and they include texts such as the Gunpo Jeoshu, which 176 00:10:14,960 --> 00:10:18,960 Speaker 1: was published in the sixteen fifties, and the famous mansen 177 00:10:19,040 --> 00:10:23,520 Speaker 1: Shuki or bensen Chukai from around sixteen seventy six, the 178 00:10:23,600 --> 00:10:26,720 Speaker 1: latter of which has in some instances been referred to 179 00:10:26,840 --> 00:10:30,319 Speaker 1: as the Ninja Bible, though this is probably a misleading 180 00:10:30,360 --> 00:10:34,880 Speaker 1: way to characterize it. Mens In Chuki or bensen Chukai 181 00:10:35,320 --> 00:10:39,120 Speaker 1: the title means ten thousand rivers flowing together into an ocean, 182 00:10:39,960 --> 00:10:43,120 Speaker 1: and in particular this one is the source of a 183 00:10:43,240 --> 00:10:47,640 Speaker 1: lot of modern ninja lore. It contains details about ingenious 184 00:10:47,720 --> 00:10:52,400 Speaker 1: ninja gadgets and equipment. It also contains different philosophies about 185 00:10:52,440 --> 00:10:56,440 Speaker 1: spying and infiltration. It makes an interesting distinction between what 186 00:10:56,480 --> 00:11:01,120 Speaker 1: it calls yonin and enin Yonin meaning open infiltration. So 187 00:11:01,160 --> 00:11:04,800 Speaker 1: this would be sneaking into somewhere by wearing a disguise 188 00:11:05,040 --> 00:11:08,200 Speaker 1: or being accepted by the target community, so you are 189 00:11:08,600 --> 00:11:14,120 Speaker 1: within view, but you are disguising your intentions in some way. Meanwhile, 190 00:11:14,160 --> 00:11:17,400 Speaker 1: in en means invisibility or hiding, so this would be 191 00:11:17,440 --> 00:11:21,280 Speaker 1: infiltration by sneaking by night or hiding under floorboards. 192 00:11:22,040 --> 00:11:24,080 Speaker 3: And that's where we get into some of these the 193 00:11:24,120 --> 00:11:28,559 Speaker 3: elements of patients and endurance that we mentioned in the 194 00:11:28,640 --> 00:11:31,120 Speaker 3: last episode. I believe, like, if you're going to have 195 00:11:31,120 --> 00:11:34,360 Speaker 3: to hide under the floorboards for let's say forty eight hours, 196 00:11:35,040 --> 00:11:38,640 Speaker 3: you know you're going to have to use some chenobi patients. 197 00:11:38,880 --> 00:11:41,120 Speaker 1: That's right. And that's one reason that there may not 198 00:11:41,200 --> 00:11:46,320 Speaker 1: be as much difference between the idea of practicing endurance 199 00:11:46,400 --> 00:11:49,680 Speaker 1: or patients and practicing stealth as you might originally think, 200 00:11:49,800 --> 00:11:53,040 Speaker 1: like a lot of stealth is patience. In fact, you 201 00:11:53,080 --> 00:11:55,800 Speaker 1: could even argue that that patience is very important when 202 00:11:55,840 --> 00:11:59,080 Speaker 1: you are just being accepted within a target community or 203 00:11:59,080 --> 00:12:01,120 Speaker 1: in disguise. Right, you've got to play the part for 204 00:12:01,200 --> 00:12:03,439 Speaker 1: a long time to sort of make people comfortable. 205 00:12:03,800 --> 00:12:06,160 Speaker 3: Yeah, yeah, you got to actually run that business. Like, 206 00:12:06,800 --> 00:12:10,160 Speaker 3: don't offer like really deep discounts. They're going to be suspicious. 207 00:12:10,520 --> 00:12:12,800 Speaker 3: Don't act like you're not interested in making a profit 208 00:12:12,840 --> 00:12:15,559 Speaker 3: one way or the other. Yeah, become a part of 209 00:12:15,600 --> 00:12:17,280 Speaker 3: the community and then betray them. 210 00:12:17,679 --> 00:12:21,320 Speaker 1: Another interesting thing about these ninjasu manuals is the thing 211 00:12:21,320 --> 00:12:25,880 Speaker 1: that makes them really tempting to interpret is that sometimes 212 00:12:25,920 --> 00:12:30,120 Speaker 1: they might include explanations and references that seem kind of circumspect, 213 00:12:30,280 --> 00:12:32,400 Speaker 1: like they don't give all the details of what they're 214 00:12:32,400 --> 00:12:35,160 Speaker 1: talking about. And then sometimes they'll have a note like 215 00:12:35,480 --> 00:12:38,360 Speaker 1: additional information is only to be passed on by word 216 00:12:38,400 --> 00:12:38,880 Speaker 1: of mouth. 217 00:12:39,200 --> 00:12:42,920 Speaker 3: Oh boy, that sounds very shanobi. 218 00:12:43,280 --> 00:12:46,360 Speaker 1: Yeah. One random detail that I love, by the way, 219 00:12:46,480 --> 00:12:49,280 Speaker 1: just came across this in the book. This is about 220 00:12:49,320 --> 00:12:54,000 Speaker 1: the gun pogoshu. It's the claim that in the ancient past, 221 00:12:54,200 --> 00:12:57,800 Speaker 1: men of the regions Ega and Coca, which are places 222 00:12:57,800 --> 00:13:01,319 Speaker 1: in Japan that are the have long been claimed as 223 00:13:01,440 --> 00:13:05,160 Speaker 1: national headquarters of shinobi training. So the claim is that 224 00:13:05,240 --> 00:13:08,840 Speaker 1: these these ninja from IgA and Coca would travel as 225 00:13:09,040 --> 00:13:13,960 Speaker 1: secret agents, and while doing so, they would pose as yamabushi, 226 00:13:14,120 --> 00:13:18,920 Speaker 1: which means street performers such as monkey tamers. So like 227 00:13:19,040 --> 00:13:21,000 Speaker 1: the next time you see a busker playing a Goo 228 00:13:21,000 --> 00:13:23,079 Speaker 1: Goo Dolls song on the sidewalk, or you see a 229 00:13:23,080 --> 00:13:26,120 Speaker 1: guy dressed up as Superman in Times Square, you might 230 00:13:26,160 --> 00:13:29,439 Speaker 1: wonder is this a ninja? Is this person gathering intelligence? 231 00:13:30,640 --> 00:13:34,640 Speaker 1: Another interesting fact about the gun Pogoshu in particular is 232 00:13:34,679 --> 00:13:37,480 Speaker 1: that some of its espionage advice is given in the 233 00:13:37,520 --> 00:13:40,560 Speaker 1: form of a collection of poems, poems about spying. 234 00:13:41,240 --> 00:13:44,480 Speaker 3: Wow. Wow, that's fascinating that. Yeah, this goes hand in 235 00:13:44,520 --> 00:13:46,240 Speaker 3: hand with some of the things we've been talking about 236 00:13:46,240 --> 00:13:50,880 Speaker 3: about disguising yourself blending in. But I guess sometimes like 237 00:13:50,960 --> 00:13:54,480 Speaker 3: being the obnoxiously obvious person is also a way of 238 00:13:54,520 --> 00:13:57,960 Speaker 3: blending into the background, like nobody suspects the like the 239 00:13:58,000 --> 00:14:01,000 Speaker 3: Times Square Elmo of well, you suspect the Times Square 240 00:14:01,000 --> 00:14:04,880 Speaker 3: Elmo of things, but probably not espionage. 241 00:14:04,360 --> 00:14:17,320 Speaker 1: Right exactly anyway, So, with all the caveats we've previously 242 00:14:17,400 --> 00:14:21,320 Speaker 1: established about the historicity of what's in these manuals that 243 00:14:21,480 --> 00:14:25,280 Speaker 1: you know, we might regard them with some historical skepticism. Nevertheless, 244 00:14:25,320 --> 00:14:29,120 Speaker 1: they do describe a lot of fascinating alleged tricks and 245 00:14:29,240 --> 00:14:33,240 Speaker 1: tools of ninjasu. So I think we should just dive 246 00:14:33,320 --> 00:14:36,280 Speaker 1: right in and talk about some alleged ninja techniques. 247 00:14:36,640 --> 00:14:38,120 Speaker 3: Yeah, I want to pick up talking a little a 248 00:14:38,240 --> 00:14:42,400 Speaker 3: bit about the female shinobi or the kuno ichi, which 249 00:14:42,400 --> 00:14:44,880 Speaker 3: I believe we mentioned in passing in the first episode. 250 00:14:45,320 --> 00:14:47,640 Speaker 3: You know, the idea that we could have both male 251 00:14:47,680 --> 00:14:53,040 Speaker 3: and female ninja, and this does really stress the the 252 00:14:53,160 --> 00:14:58,720 Speaker 3: reality that that shinobi activities would have covered a lot 253 00:14:58,760 --> 00:15:03,240 Speaker 3: of ground that isn't just concerned with assassination or military 254 00:15:03,280 --> 00:15:06,880 Speaker 3: and military and you know, direct military adjacent combat adjacent activities, 255 00:15:06,880 --> 00:15:10,760 Speaker 3: but get into all these areas of spycraft. And there 256 00:15:10,800 --> 00:15:13,720 Speaker 3: is apparently, according to Yoda and Ault in their book 257 00:15:13,720 --> 00:15:16,720 Speaker 3: on Ninja's that I that I cited in the previous episodes, 258 00:15:17,080 --> 00:15:21,320 Speaker 3: there there's no evidence that female shanoby ever engaged in combat, 259 00:15:22,120 --> 00:15:25,160 Speaker 3: though of course there are historic examples of Japanese women 260 00:15:25,520 --> 00:15:28,840 Speaker 3: serving as warriors, such as tome Gozen of the late 261 00:15:28,880 --> 00:15:32,280 Speaker 3: twelfth century. So so again not saying there weren't female 262 00:15:32,320 --> 00:15:37,840 Speaker 3: warriors in Japanese history, and even that there weren't female 263 00:15:37,880 --> 00:15:40,760 Speaker 3: shanoby operatives who engaged in combat, but there's no evidence 264 00:15:40,800 --> 00:15:47,120 Speaker 3: of such, but there there are writings about female shanobi operatives, 265 00:15:47,560 --> 00:15:50,600 Speaker 3: and this makes sense for reasons we already stressed, like 266 00:15:50,680 --> 00:15:53,840 Speaker 3: if you were going to engage in spycraft, you you're 267 00:15:53,920 --> 00:15:56,360 Speaker 3: you're going to take advantage of whatever tools are at 268 00:15:56,400 --> 00:15:59,160 Speaker 3: your disposal, and there are going to be certain segments 269 00:15:59,160 --> 00:16:02,880 Speaker 3: of society through which females are going to be able 270 00:16:02,880 --> 00:16:04,920 Speaker 3: to travel with a little more ease or a little 271 00:16:05,040 --> 00:16:09,640 Speaker 3: less notice. There And as we mentioned last time, there 272 00:16:09,680 --> 00:16:14,760 Speaker 3: is at least one named female ninja, Mochizuki chi Yojo, 273 00:16:15,080 --> 00:16:18,880 Speaker 3: and this individual's still somewhat of a mystery. There are 274 00:16:18,880 --> 00:16:22,160 Speaker 3: some arguments that she didn't exist at all, but Yoda 275 00:16:22,160 --> 00:16:26,520 Speaker 3: and all lister existence has confirmed, so I guess there 276 00:16:26,640 --> 00:16:28,600 Speaker 3: is a certain amount of evidence on one side of 277 00:16:28,600 --> 00:16:31,080 Speaker 3: the argument to say that this person did exist in 278 00:16:31,080 --> 00:16:34,840 Speaker 3: some form. Assuming she did exist, however, she would have 279 00:16:34,880 --> 00:16:38,200 Speaker 3: been like a poet, a noble woman, and it's said 280 00:16:38,240 --> 00:16:41,480 Speaker 3: that she was affiliated with the Takata samurai clan and 281 00:16:41,520 --> 00:16:44,800 Speaker 3: to have presided over a team of the uruki miko 282 00:16:45,160 --> 00:16:47,320 Speaker 3: or walking maidens. So she would have kind of like 283 00:16:47,480 --> 00:16:51,360 Speaker 3: been a spymaster of female shanov and so on the 284 00:16:51,400 --> 00:16:53,920 Speaker 3: realistic end of things, if there's truth to any of this, 285 00:16:54,640 --> 00:16:57,560 Speaker 3: whether we were dealing with the specifics of this individual or 286 00:16:57,600 --> 00:17:00,880 Speaker 3: just the general idea that there were females spy operatives 287 00:17:01,560 --> 00:17:04,760 Speaker 3: in Japan during the Warring States period, just as there 288 00:17:04,800 --> 00:17:08,359 Speaker 3: have been female spy operatives in pretty much every culture. 289 00:17:08,400 --> 00:17:10,040 Speaker 3: I think, every culture, I think we will be a 290 00:17:10,080 --> 00:17:15,400 Speaker 3: safe assumption these would have been female operatives who could 291 00:17:15,440 --> 00:17:21,040 Speaker 3: travel around, often as Shinto holy women, as entertainers, or 292 00:17:21,119 --> 00:17:25,479 Speaker 3: perhaps prostitutes. Now on the legendary end of the spectrum, however, 293 00:17:25,680 --> 00:17:29,640 Speaker 3: female shanobi were often imbued with various powers that were 294 00:17:29,680 --> 00:17:32,679 Speaker 3: linked to female sexuality and reproduction, and a lot of 295 00:17:32,720 --> 00:17:36,840 Speaker 3: this has much in common with various witchlike belief systems 296 00:17:36,880 --> 00:17:39,800 Speaker 3: from around the world, you know, even getting into ideas 297 00:17:39,840 --> 00:17:43,479 Speaker 3: of like the monstrous feminine, you know, the other ring 298 00:17:43,600 --> 00:17:47,680 Speaker 3: of the female, and taking aspects of reproduction and sexuality 299 00:17:47,720 --> 00:17:51,040 Speaker 3: and tweaking them into the you know, the demonic realm 300 00:17:51,080 --> 00:17:55,200 Speaker 3: and so forth. But this also put me very much 301 00:17:55,240 --> 00:17:58,000 Speaker 3: in mind of the Beni Jesert from Frank Herbert's done, 302 00:17:58,400 --> 00:18:02,920 Speaker 3: as well as their later series counterparts, the Honored Matre 303 00:18:04,080 --> 00:18:06,320 Speaker 3: or kind of like a splinter of the Benijesterrit, who 304 00:18:06,359 --> 00:18:09,440 Speaker 3: are their opposition. So I wanted to run through some 305 00:18:09,520 --> 00:18:12,280 Speaker 3: of the powers and abilities attributed to them. Again, we're 306 00:18:12,320 --> 00:18:17,280 Speaker 3: dealing very much with the legendary supernatural end of the 307 00:18:17,440 --> 00:18:22,800 Speaker 3: of the ninja pop cultural world here and not historic reality, 308 00:18:22,880 --> 00:18:26,320 Speaker 3: though perhaps you know, if you read between the lines, 309 00:18:26,359 --> 00:18:30,439 Speaker 3: you can sort of see like realistic spycraft, you know, 310 00:18:30,520 --> 00:18:32,960 Speaker 3: at the heart of some of these legends. So according 311 00:18:32,960 --> 00:18:35,400 Speaker 3: to Yoda and All, there were several abilities that were 312 00:18:35,440 --> 00:18:38,560 Speaker 3: said to be linked to conception, such as the power 313 00:18:38,600 --> 00:18:42,040 Speaker 3: to remove an unborn child from the womb, change its features, 314 00:18:42,359 --> 00:18:46,639 Speaker 3: and then return it to the womb. Also the transfer 315 00:18:46,680 --> 00:18:50,040 Speaker 3: of an unborn child from one woman to another, and 316 00:18:50,160 --> 00:18:53,159 Speaker 3: the ability for female shinobi to choose to have a 317 00:18:53,200 --> 00:18:56,359 Speaker 3: baby with any partner they've slept with over the last 318 00:18:56,400 --> 00:18:59,959 Speaker 3: ten months. This last one I found pretty interesting because 319 00:19:00,160 --> 00:19:05,160 Speaker 3: some organisms actually do engage in female sperm storage, a 320 00:19:05,200 --> 00:19:08,040 Speaker 3: form of sexual selection by which sperm cells are retained 321 00:19:08,040 --> 00:19:11,040 Speaker 3: by the receiving female for a period, sometimes a prolong 322 00:19:11,119 --> 00:19:15,040 Speaker 3: period of time before using said sperm. Human beings do 323 00:19:15,119 --> 00:19:19,480 Speaker 3: not do this, but you do find some organisms that do. 324 00:19:19,680 --> 00:19:21,160 Speaker 1: I recall reading about sharks. 325 00:19:21,400 --> 00:19:27,240 Speaker 3: Yes, yes, sharks are a great example. And yeah, sometimes 326 00:19:27,240 --> 00:19:31,960 Speaker 3: this involves post copulatory cryptic female choice. I believe the 327 00:19:32,040 --> 00:19:37,600 Speaker 3: terminology via various methods. So it is interesting that, yeah, 328 00:19:37,600 --> 00:19:42,040 Speaker 3: this is a supposed ability of legendary mythic female ninja, 329 00:19:42,119 --> 00:19:45,359 Speaker 3: but you have to go into the animal world to 330 00:19:45,440 --> 00:19:48,560 Speaker 3: find examples of it in reality. Now, it should also 331 00:19:48,600 --> 00:19:50,600 Speaker 3: come as no surprise, given the sort of fem fatale 332 00:19:50,720 --> 00:19:53,800 Speaker 3: nature of female ninja and pop culture, that some of 333 00:19:53,840 --> 00:19:57,960 Speaker 3: their weapons are related to seduction and sex. If go 334 00:19:58,000 --> 00:20:00,960 Speaker 3: ahead and maybe skip fifteen seconds of this if you 335 00:20:01,040 --> 00:20:04,000 Speaker 3: just want to skip the the very mild details here, 336 00:20:04,760 --> 00:20:08,440 Speaker 3: but here they are. They include death by orgasm, death 337 00:20:08,480 --> 00:20:12,880 Speaker 3: by reversing the male's reproductive ejections, shall we say, back 338 00:20:12,920 --> 00:20:16,199 Speaker 3: into his body, killing him in the process. And then 339 00:20:16,240 --> 00:20:19,520 Speaker 3: there's the technique where they seduce a man so hard 340 00:20:20,000 --> 00:20:22,080 Speaker 3: that he's mentally turned into an infant. 341 00:20:22,440 --> 00:20:22,760 Speaker 1: HM. 342 00:20:23,080 --> 00:20:24,320 Speaker 3: Great trick if you can pull it off. 343 00:20:24,520 --> 00:20:25,680 Speaker 1: Yeah. 344 00:20:25,920 --> 00:20:28,400 Speaker 3: Now, I'm not sure that Frank Herbert was directly inspired 345 00:20:28,440 --> 00:20:30,200 Speaker 3: by any of this, And if I had to guess 346 00:20:30,240 --> 00:20:32,439 Speaker 3: I would say he was probably not, but I have 347 00:20:32,560 --> 00:20:35,560 Speaker 3: read that he did study Japanese and Chinese culture, among 348 00:20:36,119 --> 00:20:38,560 Speaker 3: so many other things, so it's not impossible that he 349 00:20:38,640 --> 00:20:41,600 Speaker 3: got some inspiration from all of this. And certainly, like 350 00:20:41,640 --> 00:20:47,560 Speaker 3: some of these, the detailed classifications of spycraft, we do 351 00:20:47,680 --> 00:20:50,800 Speaker 3: see these reflected in the Dune series. You know, it's 352 00:20:51,040 --> 00:20:56,080 Speaker 3: just thinking earlier about the Hearkenans hiding somebody away in 353 00:20:56,160 --> 00:21:00,760 Speaker 3: the walls in Araken as an assass a nation attempt 354 00:21:00,840 --> 00:21:03,000 Speaker 3: on the royal household. You know, there's somebody who's like 355 00:21:03,080 --> 00:21:07,120 Speaker 3: locked up for days or whatnot. You know, so who knows, 356 00:21:07,200 --> 00:21:10,199 Speaker 3: Maybe he was inspired by it, maybe not. Now for 357 00:21:10,440 --> 00:21:14,040 Speaker 3: other magical arts attributed to the ninja, well, we've already 358 00:21:14,040 --> 00:21:18,359 Speaker 3: mentioned the fictional phantom toad summoning of Juriah, but there 359 00:21:18,359 --> 00:21:21,320 Speaker 3: are some other interesting ones as well, and Yoda and 360 00:21:21,359 --> 00:21:23,080 Speaker 3: all mentioned some of these, And again, not all of 361 00:21:23,119 --> 00:21:26,760 Speaker 3: these are definitely classified as ninja or shnobi, but a 362 00:21:26,760 --> 00:21:29,720 Speaker 3: lot of them are kind of shinobi adjacent. And then 363 00:21:29,760 --> 00:21:32,120 Speaker 3: again you have to think about the fact that as 364 00:21:32,800 --> 00:21:37,840 Speaker 3: ninja myths in the popular culture kind of coalesce, they're 365 00:21:37,880 --> 00:21:41,840 Speaker 3: going to draw in multiple things. So one figure worth 366 00:21:41,880 --> 00:21:47,000 Speaker 3: looking at is sixteenth century sage Kashin Kogi, not a ninja, 367 00:21:47,119 --> 00:21:50,639 Speaker 3: more of a wizard, attributed with various acts of illusion 368 00:21:50,880 --> 00:21:55,000 Speaker 3: and shape shifting. So he would do things like allegedly 369 00:21:55,080 --> 00:21:58,560 Speaker 3: throw leaves into the water and make them turn into fish. 370 00:21:58,640 --> 00:22:01,560 Speaker 3: Various other entertaining illusion instead are maybe not that far 371 00:22:01,680 --> 00:22:06,160 Speaker 3: remove from the idea of somebody doing little illusionary tricks 372 00:22:06,600 --> 00:22:08,440 Speaker 3: on the sidewalk or in a subway station. 373 00:22:08,840 --> 00:22:10,960 Speaker 1: Oh that's interesting, yeah. 374 00:22:10,760 --> 00:22:13,879 Speaker 3: But yeah, he was according to legend, he was something 375 00:22:13,880 --> 00:22:17,959 Speaker 3: of a trickster for sure. For instance, there's this story 376 00:22:18,000 --> 00:22:20,879 Speaker 3: that he painted a detailed illustration of the torments of 377 00:22:20,960 --> 00:22:24,119 Speaker 3: Hell that when he looked at it, it seemed animated 378 00:22:24,160 --> 00:22:27,119 Speaker 3: to the naked eye, So you know, do with that 379 00:22:27,240 --> 00:22:29,480 Speaker 3: what you will. Maybe it was just like really detailed. 380 00:22:29,720 --> 00:22:33,200 Speaker 3: Maybe there was some sort of effect involved, or it 381 00:22:33,240 --> 00:22:36,520 Speaker 3: was magic. You know, he's a magical painter, and it 382 00:22:36,560 --> 00:22:38,920 Speaker 3: looks like it moves like you know, Harry Potter style 383 00:22:39,000 --> 00:22:41,560 Speaker 3: or something, and everybody was really impressed by it, and 384 00:22:41,600 --> 00:22:44,200 Speaker 3: in fact, the powerful Daimyo some called him the demon 385 00:22:44,280 --> 00:22:49,360 Speaker 3: Daimyo Nabunaga, insisted on buying it, and the negotiations apparently 386 00:22:49,359 --> 00:22:53,720 Speaker 3: included at least one assassination attempt on the artist, and 387 00:22:54,000 --> 00:22:57,960 Speaker 3: you know, but Cogie stuck to his guns and finally 388 00:22:58,000 --> 00:23:00,359 Speaker 3: agreed to sell it for just a crazy son, just 389 00:23:01,320 --> 00:23:03,800 Speaker 3: I don't know how much, but a lot, at which 390 00:23:03,840 --> 00:23:08,679 Speaker 3: point the art suddenly lost its animated magic and Nabanaga 391 00:23:08,720 --> 00:23:11,880 Speaker 3: is like, what happened? Why is it not moving anymore? 392 00:23:11,920 --> 00:23:15,600 Speaker 3: Why is it not as amazing as was previously? And 393 00:23:15,640 --> 00:23:18,760 Speaker 3: he's like, well, it used to be priceless, but then 394 00:23:18,760 --> 00:23:20,679 Speaker 3: we agreed on a price, and so the quality of 395 00:23:20,680 --> 00:23:23,920 Speaker 3: the piece adjusted to that price sounds like a great 396 00:23:23,920 --> 00:23:25,639 Speaker 3: way to get beheaded. But I don't know. You know, 397 00:23:25,640 --> 00:23:28,280 Speaker 3: that's the thing about being a trickster, daring, trickster wizard. 398 00:23:28,320 --> 00:23:30,240 Speaker 3: You can pull these things off. I guess. 399 00:23:30,840 --> 00:23:33,680 Speaker 1: Artists in the audience remember this negotiating. 400 00:23:33,119 --> 00:23:36,160 Speaker 3: Tape again, Yeah, yeah, try and pull that one off. 401 00:23:36,440 --> 00:23:38,879 Speaker 3: So Koji again not a ninja, but a figure that 402 00:23:38,920 --> 00:23:43,040 Speaker 3: crosses over with some of the attributed magics of the ninja, 403 00:23:43,520 --> 00:23:46,119 Speaker 3: and as a pop culture figure, he does pop up 404 00:23:46,119 --> 00:23:48,920 Speaker 3: in a lot of ninja media, such as nineteen eighty 405 00:23:48,920 --> 00:23:53,400 Speaker 3: two's Ninja Wars aka Death of a Ninja starring hero 406 00:23:53,480 --> 00:23:56,679 Speaker 3: Yuki Sonata, a major actor who would go on to 407 00:23:56,800 --> 00:23:59,040 Speaker 3: of course have a starring role in the recent Showgun 408 00:23:59,119 --> 00:24:02,840 Speaker 3: series on FX. But also he played Scorpion the ninja 409 00:24:03,000 --> 00:24:05,639 Speaker 3: in one of those in that recent Mortal Kombat film. 410 00:24:05,720 --> 00:24:09,360 Speaker 3: So definitely a figure that has immersed in the ninja lore, 411 00:24:09,400 --> 00:24:10,879 Speaker 3: and I think he's popped up in a film or 412 00:24:10,880 --> 00:24:14,520 Speaker 3: two for Weird House cinema. Great actor. I have not 413 00:24:14,600 --> 00:24:16,840 Speaker 3: seen Ninja Wars though, so I can't really vouch for it. 414 00:24:17,400 --> 00:24:21,360 Speaker 3: All right, shall we get into some more alleged ninja 415 00:24:21,359 --> 00:24:22,720 Speaker 3: technologies of note? 416 00:24:23,000 --> 00:24:24,399 Speaker 1: Yes, absolutely so. 417 00:24:24,440 --> 00:24:27,600 Speaker 3: As we previously discussed, the modern trope of the ninja 418 00:24:27,840 --> 00:24:30,800 Speaker 3: typically involves their use of a traditional martial art that 419 00:24:30,880 --> 00:24:34,840 Speaker 3: prioritizes medieval weaponry. Right, so these ninjas will use a 420 00:24:34,960 --> 00:24:38,320 Speaker 3: schuriken to bypass a security panel. They will kill a 421 00:24:38,440 --> 00:24:41,040 Speaker 3: robot with a sword, right, you know exactly what I'm 422 00:24:41,040 --> 00:24:41,640 Speaker 3: getting at here? 423 00:24:41,680 --> 00:24:42,840 Speaker 1: Oh? Yes, yeah. 424 00:24:42,880 --> 00:24:46,120 Speaker 3: In reality, though, as we've been stressing, the shanobi would 425 00:24:46,160 --> 00:24:49,000 Speaker 3: have used whatever tools were necessarily and available to them, 426 00:24:49,040 --> 00:24:53,000 Speaker 3: including what was essentially cutting edge technology like the latest 427 00:24:53,040 --> 00:24:56,800 Speaker 3: in explosives, the latest in chemistry, the latest in firearms. 428 00:24:57,280 --> 00:24:59,720 Speaker 3: And so we do have some examples of the sort 429 00:24:59,720 --> 00:25:03,600 Speaker 3: of thing again with the huge caveat that we have 430 00:25:03,680 --> 00:25:07,600 Speaker 3: a lot of crossing of history and legend here. But 431 00:25:08,119 --> 00:25:14,080 Speaker 3: fifteenth century Shnobi commander Mochiuki Izumo no Kami is said 432 00:25:14,119 --> 00:25:19,520 Speaker 3: to have utilized smoke bombs, pyrotechnics, code signals, and some 433 00:25:19,680 --> 00:25:22,960 Speaker 3: form of weather prediction. And I'm not sure to what 434 00:25:23,040 --> 00:25:27,960 Speaker 3: extent we're talking about weather prediction that based on acceptable 435 00:25:28,000 --> 00:25:30,160 Speaker 3: models and methods or something that was maybe a little 436 00:25:30,200 --> 00:25:34,720 Speaker 3: more supernatural in form, but you know, both are likely 437 00:25:34,760 --> 00:25:35,639 Speaker 3: to some degree. 438 00:25:35,960 --> 00:25:38,440 Speaker 1: Yeah, Remember some of these ninja tsu manuals did involve 439 00:25:38,520 --> 00:25:40,120 Speaker 1: like divination and astrology. 440 00:25:40,520 --> 00:25:43,159 Speaker 3: Yeah, and so ninja throughout the centuries were said to 441 00:25:43,320 --> 00:25:48,199 Speaker 3: use noarroshi no jutsu smoke bombs, though yoda and all stresses. 442 00:25:48,280 --> 00:25:52,240 Speaker 3: These were likely quote carefully placed in ignited smoke pots, 443 00:25:52,960 --> 00:25:56,480 Speaker 3: given the limited pyrotechnic abilities of the time, and that 444 00:25:56,600 --> 00:25:58,600 Speaker 3: also they would use things that we would think of 445 00:25:58,640 --> 00:26:01,560 Speaker 3: as just simple firecrackers to serve as distractions, you know, 446 00:26:01,960 --> 00:26:05,040 Speaker 3: set off a little pop over here, just enough distraction 447 00:26:05,119 --> 00:26:06,960 Speaker 3: to do whatever it is you need to do, be 448 00:26:07,119 --> 00:26:11,040 Speaker 3: that something more pop culture ninja ish as sneak from 449 00:26:11,080 --> 00:26:13,840 Speaker 3: one point to another, or you know, switch out a 450 00:26:13,840 --> 00:26:15,960 Speaker 3: piece of paper in an office, that sort of thing. 451 00:26:17,359 --> 00:26:20,040 Speaker 3: But yeah, the smoke bombs, of course are a huge 452 00:26:20,080 --> 00:26:21,680 Speaker 3: part of the Ninja myth, and they spill over into 453 00:26:21,680 --> 00:26:24,240 Speaker 3: Batman as well, like Batman's always throwing smoke bombs and 454 00:26:24,280 --> 00:26:29,040 Speaker 3: disappearing right, and the reality is maybe less as instantly 455 00:26:29,440 --> 00:26:33,200 Speaker 3: dramatic as that. It might have been more something that 456 00:26:33,320 --> 00:26:36,000 Speaker 3: involved like placing something, lighting it and waiting for the 457 00:26:36,040 --> 00:26:39,960 Speaker 3: smoke to build up. Right. Now, getting into the use 458 00:26:40,119 --> 00:26:44,280 Speaker 3: of weaponry, we have the example of sixteenth century assassin 459 00:26:44,840 --> 00:26:49,200 Speaker 3: of Sujatini Zunjubo, and he is noted for his use 460 00:26:49,240 --> 00:26:53,080 Speaker 3: of the Japanese matchlock rifle. So this is an individual 461 00:26:53,119 --> 00:26:59,600 Speaker 3: that was definitely an assassin, definitely an attempted assassin, definitely 462 00:26:59,760 --> 00:27:03,560 Speaker 3: a marksman. Was he a shnobi, I don't know. I'm 463 00:27:03,560 --> 00:27:05,199 Speaker 3: not as sure on that. I think you could say 464 00:27:05,240 --> 00:27:08,200 Speaker 3: that he definitely engaged in a major shnobi activity, though 465 00:27:08,920 --> 00:27:11,919 Speaker 3: this was apparently a Codo clan marksman task with the 466 00:27:11,960 --> 00:27:17,720 Speaker 3: assassination of Oda Nobuniga himself, a local warlord was said 467 00:27:17,760 --> 00:27:19,679 Speaker 3: to have hired him for the task and provided with 468 00:27:19,760 --> 00:27:24,080 Speaker 3: key intel about Nabonaga's scheduled transit through a particular pass 469 00:27:24,200 --> 00:27:27,920 Speaker 3: in Omi. This would have been on May nineteenth, fifteen seventy, 470 00:27:28,720 --> 00:27:32,080 Speaker 3: so you know basic you know, sort of sniper operations. 471 00:27:32,119 --> 00:27:35,720 Speaker 3: Here he set up a position days in advance, using 472 00:27:35,880 --> 00:27:40,000 Speaker 3: like the patients of the shnoby if nothing else until okay, 473 00:27:40,040 --> 00:27:43,520 Speaker 3: here it comes the retinue. Here comes Nabunka in armor 474 00:27:43,600 --> 00:27:47,040 Speaker 3: on his on his steed, accompanied by all of his men, 475 00:27:47,760 --> 00:27:52,000 Speaker 3: and our would be assassin. Here Zenjubo knows that he 476 00:27:52,080 --> 00:27:55,960 Speaker 3: really only has one shot. You know, this is this 477 00:27:56,000 --> 00:27:59,280 Speaker 3: is a matchlock rifle. You know, he's not rapid fire. 478 00:28:00,240 --> 00:28:02,840 Speaker 3: He's going to get one shot off and then it's 479 00:28:02,880 --> 00:28:04,720 Speaker 3: going to be so loud and it's going to produce 480 00:28:04,800 --> 00:28:07,399 Speaker 3: a discharge of smoke. And he's not like, you know, 481 00:28:07,520 --> 00:28:10,439 Speaker 3: miles away or anything. So he knows that the instant 482 00:28:10,440 --> 00:28:14,720 Speaker 3: he fires this shot, they're gonna mark his position, and 483 00:28:14,800 --> 00:28:17,119 Speaker 3: so he needs to he needs to make sure that 484 00:28:17,119 --> 00:28:19,239 Speaker 3: that shot lands home or he's gonna have to like 485 00:28:19,280 --> 00:28:21,400 Speaker 3: try and get off the second one if he can. 486 00:28:22,119 --> 00:28:25,159 Speaker 3: So he fires the shot, knocks in Abunika from his horse, 487 00:28:25,880 --> 00:28:28,639 Speaker 3: but as it turns out, does not kill him because 488 00:28:28,680 --> 00:28:32,000 Speaker 3: the collar armor that he's wearing absorbs the shot, so 489 00:28:32,200 --> 00:28:36,280 Speaker 3: Zenjubo flees, he hides that he is eventually caught and 490 00:28:36,320 --> 00:28:40,520 Speaker 3: subjected to slow execution. I believe the story is that 491 00:28:40,560 --> 00:28:42,640 Speaker 3: they buried him up to his neck in the sand 492 00:28:42,720 --> 00:28:44,080 Speaker 3: and like sawed his head off. 493 00:28:44,400 --> 00:28:44,680 Speaker 1: Wow. 494 00:28:45,080 --> 00:28:48,200 Speaker 3: Now it was worth noting that snipers then and now 495 00:28:49,120 --> 00:28:53,240 Speaker 3: sometimes utilize breathing techniques to steady one's aim in. Various 496 00:28:53,280 --> 00:28:55,560 Speaker 3: breathing techniques and things that you could also think of 497 00:28:55,600 --> 00:28:58,880 Speaker 3: as like self hypnosis have also been attributed to the 498 00:28:58,880 --> 00:29:03,760 Speaker 3: shinobi general to aid in stealth or patience. Now, at 499 00:29:03,760 --> 00:29:05,760 Speaker 3: this point, let's come back to the idea of a 500 00:29:05,880 --> 00:29:09,320 Speaker 3: ninja sword, something that is just inseparable from the modern 501 00:29:10,320 --> 00:29:13,800 Speaker 3: myth of the ninja. In fact, we already in passing 502 00:29:13,800 --> 00:29:16,320 Speaker 3: I think, talked about teenage mutant ninja turtles with katana. 503 00:29:16,880 --> 00:29:20,120 Speaker 3: You know, like, if you're gonna make turtles into ninjas, 504 00:29:20,160 --> 00:29:22,640 Speaker 3: you give one of them swords. That's just what you do. 505 00:29:23,000 --> 00:29:25,000 Speaker 3: And we actually heard from at least one listener who 506 00:29:25,040 --> 00:29:26,880 Speaker 3: wrote in and was like, oh, yeah, there's actually the 507 00:29:26,920 --> 00:29:31,200 Speaker 3: whole thing about the ninja having a specific sword, the 508 00:29:31,240 --> 00:29:37,440 Speaker 3: Shanovi katana. But as this listener pointed out, and as 509 00:29:37,480 --> 00:29:39,840 Speaker 3: it is discussed in the text we were working from, 510 00:29:40,240 --> 00:29:43,320 Speaker 3: this sword's exact form is at least a matter of 511 00:29:43,360 --> 00:29:47,000 Speaker 3: some controversy. There are a lot of strong arguments that 512 00:29:47,240 --> 00:29:50,560 Speaker 3: this sword never existed at all. This is one of 513 00:29:50,600 --> 00:29:53,520 Speaker 3: those examples where we don't see mention of it in 514 00:29:53,760 --> 00:29:59,640 Speaker 3: the historic ninja guide books and instruction manuals. There's a 515 00:29:59,760 --> 00:30:04,000 Speaker 3: very strong argument that these were created entirely in the 516 00:30:04,000 --> 00:30:07,239 Speaker 3: twentieth century. Though again this is certainly something where then 517 00:30:07,280 --> 00:30:08,840 Speaker 3: you can go around and buy one at a mall 518 00:30:08,960 --> 00:30:11,760 Speaker 3: in like Wisconsin, so you can argue that will this 519 00:30:11,800 --> 00:30:15,200 Speaker 3: shouobi katana exists now you see it in movies and 520 00:30:15,240 --> 00:30:18,800 Speaker 3: you can buy one, you know, at the mall. But 521 00:30:19,360 --> 00:30:21,960 Speaker 3: let's get into the idea of it, at least the 522 00:30:22,000 --> 00:30:23,800 Speaker 3: myth of it. The idea is that this would be 523 00:30:23,840 --> 00:30:27,440 Speaker 3: a short straight blade with a pointed scabbard, So the 524 00:30:27,480 --> 00:30:29,920 Speaker 3: scabbard has a point at the end, and also a 525 00:30:29,920 --> 00:30:33,320 Speaker 3: simple square guard you know, at the between the hilt 526 00:30:33,320 --> 00:30:36,480 Speaker 3: and the blade, and the aspects of its design were 527 00:30:36,480 --> 00:30:38,800 Speaker 3: said to be very practical for the ninja. So the 528 00:30:38,840 --> 00:30:41,760 Speaker 3: pointed scabbard allowed it to be driven into the ground, 529 00:30:41,800 --> 00:30:44,160 Speaker 3: so it could be you could serve as a footstool 530 00:30:44,200 --> 00:30:47,720 Speaker 3: to aid in climbing. I think there's some other stories 531 00:30:47,760 --> 00:30:50,800 Speaker 3: about the scabbard being used as like a breathing tube 532 00:30:50,840 --> 00:30:53,760 Speaker 3: if an engine needed to go under water. I'm not 533 00:30:53,800 --> 00:30:56,320 Speaker 3: sure why that would be more effective than having a 534 00:30:56,320 --> 00:30:59,080 Speaker 3: breathing tube on you or using a red or something. 535 00:31:00,560 --> 00:31:02,640 Speaker 1: Trying to imagine now, I think the idea with the 536 00:31:02,680 --> 00:31:05,800 Speaker 1: scabbard is that you wouldn't you could stab it into 537 00:31:05,840 --> 00:31:09,000 Speaker 1: the ground within its scabbard and then stand on the 538 00:31:09,120 --> 00:31:11,320 Speaker 1: hilt of the sword to like hop over a wall 539 00:31:11,400 --> 00:31:14,760 Speaker 1: and then like pull it up by a rope. That's 540 00:31:14,800 --> 00:31:16,440 Speaker 1: the idea, because I guess if you were to stab 541 00:31:16,520 --> 00:31:19,360 Speaker 1: the blade of the sword into the ground, the ideas 542 00:31:19,400 --> 00:31:22,480 Speaker 1: that would dull it. Yeah, But I'd also seen something 543 00:31:22,520 --> 00:31:26,239 Speaker 1: about just generally using the scabbard of this sword as 544 00:31:26,280 --> 00:31:29,600 Speaker 1: a kind of like a feeler, like an untinnee in 545 00:31:29,640 --> 00:31:30,120 Speaker 1: the dark. 546 00:31:30,680 --> 00:31:33,320 Speaker 3: Yeah. The idea that you would kind of like partially 547 00:31:33,400 --> 00:31:36,360 Speaker 3: unsheath your sword, hold it out in front of you, 548 00:31:36,880 --> 00:31:39,320 Speaker 3: and if you like taped into something, you're like, oh, 549 00:31:39,360 --> 00:31:40,959 Speaker 3: there's a person there, and then you can pull your 550 00:31:40,960 --> 00:31:43,920 Speaker 3: sword out and like slash them or something. I think 551 00:31:43,960 --> 00:31:45,960 Speaker 3: it's been referred to as like a person detector or 552 00:31:45,960 --> 00:31:48,800 Speaker 3: a people detector. And of course there's the other obvious 553 00:31:48,880 --> 00:31:52,320 Speaker 3: idea that if you're doing some sneaking around and potentially 554 00:31:52,480 --> 00:31:55,960 Speaker 3: using that weapon in a confined space, it pays for 555 00:31:56,000 --> 00:31:58,200 Speaker 3: your sword to be short as opposed to being some 556 00:31:58,240 --> 00:32:01,160 Speaker 3: sort of like a longer sword. So this would be 557 00:32:01,240 --> 00:32:04,920 Speaker 3: in keeping with operations that required disguise and so forth 558 00:32:05,120 --> 00:32:08,720 Speaker 3: easier to hide, easier to carry, and all that. So again, 559 00:32:08,920 --> 00:32:11,000 Speaker 3: very strong argument to be made that these were just 560 00:32:11,040 --> 00:32:14,840 Speaker 3: invented in the twentieth century as part of outright ninja 561 00:32:14,880 --> 00:32:18,560 Speaker 3: fiction and myth making. But something that Yoda and All 562 00:32:18,600 --> 00:32:21,240 Speaker 3: point out is that, okay, if these swords did exist, 563 00:32:22,200 --> 00:32:24,320 Speaker 3: which depending on where you land on this could be 564 00:32:24,360 --> 00:32:27,920 Speaker 3: a huge if they would have been very simple. They 565 00:32:27,920 --> 00:32:30,440 Speaker 3: wouldn't have been ornate because they would not have been 566 00:32:30,520 --> 00:32:35,040 Speaker 3: forged by a master swordsmith, one of these individuals responsible 567 00:32:35,080 --> 00:32:40,480 Speaker 3: for the just the elegant superiority of the noble samurai sword. 568 00:32:40,840 --> 00:32:43,600 Speaker 3: But rather these would have been made by blacksmiths in 569 00:32:43,640 --> 00:32:46,680 Speaker 3: the country, probably who were willing to take a risk 570 00:32:46,760 --> 00:32:51,560 Speaker 3: making an illegal sword. Because remember, your average genobi here is, 571 00:32:52,400 --> 00:32:55,000 Speaker 3: if not an actual criminal is at least a common 572 00:32:55,080 --> 00:32:58,800 Speaker 3: born person, and it was illegal for commoners to own 573 00:32:58,840 --> 00:33:01,959 Speaker 3: a weapon of any so these would have been dirty 574 00:33:01,960 --> 00:33:07,760 Speaker 3: weapons made for dirty practitioners of the sketchy arts. Yeah, 575 00:33:07,800 --> 00:33:09,520 Speaker 3: and I think we also might want to consider it 576 00:33:09,600 --> 00:33:13,640 Speaker 3: questions of necessity, right, would is Shanoby operative need a sword, 577 00:33:13,680 --> 00:33:18,280 Speaker 3: because even a small sword is fairly sizable, and especially 578 00:33:18,280 --> 00:33:20,760 Speaker 3: if you consider, well, what are you gonna use it for? 579 00:33:20,840 --> 00:33:22,920 Speaker 3: Are you gonna are you gonna engage in a sword fight? 580 00:33:23,160 --> 00:33:26,760 Speaker 3: Probably not. And if you do need some sort of 581 00:33:26,760 --> 00:33:29,800 Speaker 3: a sharp object as a weapon or a tool, well 582 00:33:29,840 --> 00:33:31,959 Speaker 3: there there are other choices you could make, such as 583 00:33:32,000 --> 00:33:37,120 Speaker 3: a common field knife, some other kind of like sharpened 584 00:33:37,120 --> 00:33:41,000 Speaker 3: tool that on one hand, maybe doesn't constitute a full weapon, 585 00:33:41,400 --> 00:33:43,480 Speaker 3: and so for you're not like you're not going to 586 00:33:43,520 --> 00:33:45,560 Speaker 3: be found out immediately just because you have it on 587 00:33:45,600 --> 00:33:47,880 Speaker 3: your person, but the kind of thing that could be 588 00:33:48,080 --> 00:33:52,080 Speaker 3: used as a weapon if things got dire m h. 589 00:33:52,640 --> 00:33:54,840 Speaker 3: And in the cases where they did use swords, yeah, 590 00:33:54,880 --> 00:33:56,920 Speaker 3: we're probably talking about the equivalent of some sort of 591 00:33:56,960 --> 00:34:09,080 Speaker 3: like a black market sword. Now, these again are all 592 00:34:09,360 --> 00:34:13,359 Speaker 3: like pretty standard pop culture ninja weapons, though I think 593 00:34:13,400 --> 00:34:16,120 Speaker 3: it's even more fun to get into some of the 594 00:34:16,280 --> 00:34:20,960 Speaker 3: perhaps weirder technologies that ninja are held to have utilized. 595 00:34:21,480 --> 00:34:25,640 Speaker 1: Right, I think it's time to talk about misugumo. Misugumo 596 00:34:26,080 --> 00:34:30,640 Speaker 1: is a device described in the sixth volume of the 597 00:34:30,680 --> 00:34:35,320 Speaker 1: seventeenth century ninjitsu manual Mensin chu Kai, which I mentioned earlier, 598 00:34:35,719 --> 00:34:39,120 Speaker 1: And the sixth volume is sort of a It describes 599 00:34:39,239 --> 00:34:42,400 Speaker 1: various pieces of ninjitsu equipment and gadget it's kind of 600 00:34:42,440 --> 00:34:47,360 Speaker 1: a C branch compendium. Now when it comes to the misugumo, 601 00:34:47,800 --> 00:34:50,959 Speaker 1: there is a way in which it has commonly been 602 00:34:51,120 --> 00:34:55,279 Speaker 1: interpreted in twentieth century sources, and then there is a 603 00:34:55,520 --> 00:34:59,160 Speaker 1: revisionist understanding of it, which I think seems much more 604 00:34:59,280 --> 00:35:02,720 Speaker 1: likely what the original sources intended. I'm going to start 605 00:35:02,760 --> 00:35:07,440 Speaker 1: off by talking about the more likely confused interpretation. So 606 00:35:07,560 --> 00:35:12,640 Speaker 1: misugumo literally means water spider, and it's clear from the 607 00:35:12,719 --> 00:35:16,400 Speaker 1: context in which this device is described that it's some 608 00:35:16,520 --> 00:35:21,520 Speaker 1: kind of flotation device. So in some popular ninja literature 609 00:35:21,560 --> 00:35:24,600 Speaker 1: of the twentieth century, it has been interpreted as a 610 00:35:24,680 --> 00:35:29,360 Speaker 1: kind of footwear that allows the ninja to walk on 611 00:35:29,520 --> 00:35:32,279 Speaker 1: top of the water, often said to be used for 612 00:35:32,560 --> 00:35:37,040 Speaker 1: crossing the watery moat surrounding a castle. So imagine a 613 00:35:37,120 --> 00:35:41,600 Speaker 1: kind of wooden sandal that is a little rectangular sandal 614 00:35:41,640 --> 00:35:44,799 Speaker 1: in the middle bound with twine in the center of 615 00:35:44,880 --> 00:35:50,120 Speaker 1: a large flat disk made out of wooden quarter circle pieces. 616 00:35:50,360 --> 00:35:54,400 Speaker 1: So you imagine a round disc with a hollow center 617 00:35:54,520 --> 00:35:58,040 Speaker 1: made out of wood cut into four different pieces, and 618 00:35:58,080 --> 00:36:00,640 Speaker 1: they're bound together with twine, and then in the middle 619 00:36:00,680 --> 00:36:03,560 Speaker 1: you've got this little flat sandal soul to stand on. 620 00:36:04,160 --> 00:36:06,520 Speaker 1: You can look up illustrations of this if you want. 621 00:36:06,560 --> 00:36:09,560 Speaker 1: But this idea, in the first interpretation, is that the 622 00:36:09,640 --> 00:36:12,759 Speaker 1: ninja would stand on these and then use them to 623 00:36:12,960 --> 00:36:16,080 Speaker 1: walk across the surface of the water, because hey, wood 624 00:36:16,080 --> 00:36:20,960 Speaker 1: floats right now. Would this actually work? Would such a 625 00:36:21,040 --> 00:36:24,560 Speaker 1: device allow you to walk on water? I think we 626 00:36:24,600 --> 00:36:27,960 Speaker 1: can start by thinking about its namesake, which is the 627 00:36:28,000 --> 00:36:33,080 Speaker 1: water spider. There are insects and spiders that are able 628 00:36:33,160 --> 00:36:36,319 Speaker 1: to walk across the surface of the water without sinking in. 629 00:36:36,400 --> 00:36:38,440 Speaker 1: There are a number of different species that can do this. 630 00:36:38,920 --> 00:36:41,680 Speaker 1: So how do they do it well? There are generally 631 00:36:41,800 --> 00:36:45,440 Speaker 1: two physical forces that they can take advantage of. One 632 00:36:45,600 --> 00:36:50,360 Speaker 1: is standard buoyancy. This works by displacing water with a 633 00:36:50,520 --> 00:36:54,960 Speaker 1: lower density object, and this is how boats float. Boats 634 00:36:54,960 --> 00:36:58,280 Speaker 1: float by having a hollow hull, thus displacing more weight 635 00:36:58,360 --> 00:37:00,680 Speaker 1: in water than their own weight, so they get to 636 00:37:00,719 --> 00:37:03,279 Speaker 1: sit on top of the water without sinking down. The 637 00:37:03,320 --> 00:37:07,920 Speaker 1: other physical factor is surface tension. Insects and spiders are 638 00:37:08,000 --> 00:37:12,160 Speaker 1: small enough that different forces play a major role in 639 00:37:12,200 --> 00:37:14,840 Speaker 1: the way they move through the world, and the surface 640 00:37:14,960 --> 00:37:18,759 Speaker 1: tension of water is one of those forces. Water is 641 00:37:18,880 --> 00:37:22,920 Speaker 1: a polar molecule, so it likes to stick to itself, 642 00:37:23,280 --> 00:37:25,920 Speaker 1: and when there's a mass of water, it forms a 643 00:37:26,040 --> 00:37:30,160 Speaker 1: kind of skin on its surface, with the water molecules 644 00:37:30,200 --> 00:37:33,480 Speaker 1: clinging very tightly to each other and to some extent 645 00:37:33,640 --> 00:37:38,360 Speaker 1: resisting being split apart. So it takes some force actually 646 00:37:38,400 --> 00:37:42,160 Speaker 1: to break through this surface layer of water. Now, given 647 00:37:42,200 --> 00:37:45,480 Speaker 1: the mass of a human body, Earth's gravity pulling us 648 00:37:45,560 --> 00:37:49,160 Speaker 1: downward into a pool of water quite easily overcomes the 649 00:37:49,200 --> 00:37:52,040 Speaker 1: surface tension of water, and we plunge right in. But 650 00:37:52,560 --> 00:37:56,520 Speaker 1: as you become smaller and smaller and your mass becomes smaller, 651 00:37:57,000 --> 00:38:01,040 Speaker 1: gravity becomes less relevant and the surface tension of water 652 00:38:01,080 --> 00:38:06,280 Speaker 1: becomes more relevant. So some insects and spiders are specially 653 00:38:06,320 --> 00:38:10,760 Speaker 1: evolved to take advantage of the power of surface tension 654 00:38:10,880 --> 00:38:15,160 Speaker 1: at their body size by having hydrophobic or water repelling 655 00:38:15,280 --> 00:38:19,560 Speaker 1: surfaces and hairs on their bodies and especially on their feet. 656 00:38:19,960 --> 00:38:23,160 Speaker 1: And these surfaces they for one thing, they spread out 657 00:38:23,200 --> 00:38:26,440 Speaker 1: their weight over a larger surface area by having like 658 00:38:26,920 --> 00:38:29,600 Speaker 1: specially shaped feed and these hairs that allow them to 659 00:38:29,680 --> 00:38:33,000 Speaker 1: kind of spread out their footprint, so they distribute their 660 00:38:33,040 --> 00:38:35,000 Speaker 1: weight over a larger surface of the water. But they 661 00:38:35,040 --> 00:38:37,960 Speaker 1: also at the molecular level, tend to be made of 662 00:38:38,280 --> 00:38:41,920 Speaker 1: hydrophobic substances that do not want to get wet. They 663 00:38:41,960 --> 00:38:45,359 Speaker 1: chemically resist getting wet, and so they do not want 664 00:38:45,440 --> 00:38:49,040 Speaker 1: to penetrate the surface level of the water. And so 665 00:38:49,360 --> 00:38:52,920 Speaker 1: with the combination of these hydrophobic surfaces and distributing their 666 00:38:52,960 --> 00:38:56,040 Speaker 1: weight over the larger space, the arthropod is able to 667 00:38:56,160 --> 00:38:58,319 Speaker 1: walk or skate over the surface of the water by 668 00:38:58,360 --> 00:39:02,360 Speaker 1: taking advantage of that surface tent. This is great for insects, 669 00:39:02,560 --> 00:39:06,200 Speaker 1: but again it works because they are extremely small and 670 00:39:06,280 --> 00:39:09,440 Speaker 1: have very small mass. Once you start getting bigger and 671 00:39:09,520 --> 00:39:12,720 Speaker 1: having more mass to your body, you're just too big 672 00:39:12,800 --> 00:39:15,239 Speaker 1: to take advantage of the surface tension of water in 673 00:39:15,320 --> 00:39:15,719 Speaker 1: this way. 674 00:39:16,400 --> 00:39:19,000 Speaker 3: So you're saying Ninja might have been just really small. 675 00:39:20,239 --> 00:39:22,839 Speaker 1: If Ninja were the size of insects. Yeah, you can 676 00:39:23,280 --> 00:39:26,279 Speaker 1: quite well imagine coming up with technology for running over 677 00:39:26,280 --> 00:39:28,719 Speaker 1: the surface of water. And that brings us back to 678 00:39:28,760 --> 00:39:32,240 Speaker 1: the Misigumo device. So I was not able to find 679 00:39:32,320 --> 00:39:37,279 Speaker 1: any rigorous testing of this device, of recreations of this 680 00:39:37,320 --> 00:39:41,040 Speaker 1: device published in a scientific or historical journal. But I've 681 00:39:41,040 --> 00:39:44,480 Speaker 1: come across a few informal tests staged in things like 682 00:39:44,520 --> 00:39:48,799 Speaker 1: documentaries and TV programs, And having reviewed this evidence and 683 00:39:48,840 --> 00:39:51,600 Speaker 1: read what I could about it, my assessment is this 684 00:39:51,680 --> 00:39:55,440 Speaker 1: device would probably not work as described, at least in 685 00:39:55,440 --> 00:39:59,600 Speaker 1: the way it's interpreted here as footwear, unless the shoes 686 00:39:59,600 --> 00:40:03,840 Speaker 1: were absurdly large, much larger than the specifications in the 687 00:40:03,920 --> 00:40:08,320 Speaker 1: Ninjasu manual indicate, in which case I question the extent 688 00:40:08,360 --> 00:40:11,440 Speaker 1: to which you could be said to walk on water 689 00:40:11,840 --> 00:40:15,239 Speaker 1: as opposed to just floating upright on two small boats. 690 00:40:15,680 --> 00:40:18,680 Speaker 1: And in that case, why is this method of crossing 691 00:40:18,719 --> 00:40:23,000 Speaker 1: the water preferable to just piloting a small raft or canoe. 692 00:40:23,040 --> 00:40:26,120 Speaker 3: Right, because a small rafter canoe works. Wonders like, there's 693 00:40:26,120 --> 00:40:30,560 Speaker 3: a reason we still use canoes and kayaks and so forth. 694 00:40:30,760 --> 00:40:33,200 Speaker 3: They're great. Why would you wear a couple of like 695 00:40:33,320 --> 00:40:36,080 Speaker 3: huge floaty clown shoes instead? Especially if you're trying to 696 00:40:36,120 --> 00:40:36,640 Speaker 3: be stealthy. 697 00:40:36,960 --> 00:40:39,560 Speaker 1: That's right. Now, you might argue, well, you know, a 698 00:40:39,680 --> 00:40:42,200 Speaker 1: rafter canoe is big and you have to it would 699 00:40:42,239 --> 00:40:44,719 Speaker 1: be hard to like carry it to the But in 700 00:40:44,880 --> 00:40:47,359 Speaker 1: order for these shoes to work, they would also need 701 00:40:47,400 --> 00:40:48,640 Speaker 1: to be big and hard to carry. 702 00:40:49,440 --> 00:40:49,640 Speaker 2: Yeah. 703 00:40:49,640 --> 00:40:52,560 Speaker 3: I mean, I'm reminded of every time as a child 704 00:40:52,680 --> 00:40:55,360 Speaker 3: or even as an adult, where I've attempted to stand 705 00:40:55,440 --> 00:40:58,799 Speaker 3: on something floating and say a swimming pool, and how 706 00:40:58,840 --> 00:41:01,600 Speaker 3: long can you stay up unless it is like a 707 00:41:01,719 --> 00:41:06,000 Speaker 3: large surfboard or a larger float, But even a fair 708 00:41:06,080 --> 00:41:08,120 Speaker 3: sized float can prove difficult. You're not going to stay 709 00:41:08,160 --> 00:41:08,759 Speaker 3: up there very long. 710 00:41:08,960 --> 00:41:10,480 Speaker 1: Yeah, that's another thing I want to get to in 711 00:41:10,520 --> 00:41:15,040 Speaker 1: just a minute. Balance. Now, there is another consideration, which 712 00:41:15,120 --> 00:41:19,239 Speaker 1: is the question of what exactly are you crossing. If 713 00:41:19,239 --> 00:41:23,560 Speaker 1: it's actually water, these these you know, water walking shoes 714 00:41:23,640 --> 00:41:27,839 Speaker 1: seem very implausible. But if it's some thicker substance like 715 00:41:27,960 --> 00:41:31,919 Speaker 1: a muddy marsh, perhaps increasing the surface area over which 716 00:41:31,920 --> 00:41:35,239 Speaker 1: your weight is distributed with these wooden disks actually would 717 00:41:35,239 --> 00:41:39,160 Speaker 1: give you an advantage walking over a mud flat or 718 00:41:39,200 --> 00:41:43,400 Speaker 1: a marsh, or some kind of thicker, thicker substrate like 719 00:41:43,440 --> 00:41:46,399 Speaker 1: that it might help to have shoes like this because 720 00:41:46,400 --> 00:41:48,839 Speaker 1: they would function more like snow shoes, you know, they 721 00:41:48,880 --> 00:41:50,040 Speaker 1: just spread your weight out. 722 00:41:50,560 --> 00:41:52,719 Speaker 3: This remind you know, remember we did some episodes on 723 00:41:52,840 --> 00:41:56,240 Speaker 3: mud a while back, right, and I remember looking into 724 00:41:56,520 --> 00:42:01,000 Speaker 3: like military experiments with mud and with vehicles. But I 725 00:42:01,000 --> 00:42:04,680 Speaker 3: believe there were also some accounts of boots, like trying 726 00:42:04,719 --> 00:42:06,840 Speaker 3: to figure out like what kind of boots would enable 727 00:42:07,080 --> 00:42:09,880 Speaker 3: soldiers to move through or across the mud easier. And 728 00:42:09,920 --> 00:42:12,440 Speaker 3: I know there were at least some experiments involving like 729 00:42:12,800 --> 00:42:16,160 Speaker 3: sort of wider shoes almost kind of like snowshoes for mud. 730 00:42:16,360 --> 00:42:18,560 Speaker 1: Right, So if you're thinking about mud or some other 731 00:42:18,640 --> 00:42:22,080 Speaker 1: kind of substrate different than just plain water, different footwear 732 00:42:22,120 --> 00:42:26,400 Speaker 1: options could have advantages. But coming back to the water walking, 733 00:42:26,800 --> 00:42:31,759 Speaker 1: like literal water walking interpretation, that seems unlikely to me. 734 00:42:32,400 --> 00:42:36,720 Speaker 1: One example of these informal tests that recreated a model 735 00:42:36,760 --> 00:42:39,399 Speaker 1: of this device and tried it out was actually MythBusters 736 00:42:39,440 --> 00:42:41,600 Speaker 1: that they did an episode where they tried it and 737 00:42:41,680 --> 00:42:44,239 Speaker 1: it did not work at all. They sank right into 738 00:42:44,239 --> 00:42:47,839 Speaker 1: the water or quickly lost upright balance and toppled over. 739 00:42:48,239 --> 00:42:51,160 Speaker 1: And they even made like much more buoyant shoes like 740 00:42:51,560 --> 00:42:54,480 Speaker 1: more buoyant, larger shoes that were different than the original 741 00:42:54,920 --> 00:42:59,880 Speaker 1: design in these Ninjasu manuals and still had trouble staying upright. 742 00:43:00,280 --> 00:43:02,919 Speaker 1: The issue is that an adult human is just way 743 00:43:02,960 --> 00:43:07,600 Speaker 1: too heavy for reasonably sized shoe worn floatation devices to 744 00:43:07,640 --> 00:43:10,280 Speaker 1: keep them afloat, So they're not going to work unless 745 00:43:10,320 --> 00:43:13,200 Speaker 1: you make the shoes gigantic. But in doing so, you 746 00:43:13,239 --> 00:43:16,799 Speaker 1: would probably lose the ability to quote walk in them 747 00:43:16,840 --> 00:43:19,279 Speaker 1: with any kind of grace, So you're just trying to 748 00:43:19,280 --> 00:43:23,719 Speaker 1: like stand up into little canoes. And this brings us 749 00:43:23,760 --> 00:43:27,240 Speaker 1: back to the how generally floatation devices on the human 750 00:43:27,280 --> 00:43:32,760 Speaker 1: scale and larger work by displacing more weight of water 751 00:43:33,280 --> 00:43:36,000 Speaker 1: than the total amount of weight that is being kept afloat. 752 00:43:36,400 --> 00:43:39,359 Speaker 1: So you can float a thousand ton boat on top 753 00:43:39,400 --> 00:43:42,480 Speaker 1: of the water if the volume of the boat displaces 754 00:43:42,520 --> 00:43:45,160 Speaker 1: more than a thousand tons of water. Right, So, you 755 00:43:45,200 --> 00:43:47,359 Speaker 1: can have a boat made out of steel that has 756 00:43:47,360 --> 00:43:50,520 Speaker 1: a hollow hull, and even though steel is very dense 757 00:43:50,560 --> 00:43:54,160 Speaker 1: and would sink in water, it's displacing more water than 758 00:43:54,200 --> 00:43:56,080 Speaker 1: the total weight of the boat and all its cargo. 759 00:43:56,880 --> 00:43:59,480 Speaker 1: So when you think about it this way, it's relatively 760 00:43:59,560 --> 00:44:03,919 Speaker 1: easy to create a personal floatation device that will keep 761 00:44:03,960 --> 00:44:08,160 Speaker 1: you from sinking entirely under the water, because once your 762 00:44:08,200 --> 00:44:13,040 Speaker 1: body is mostly submerged in the water, it's already displacing 763 00:44:13,239 --> 00:44:16,600 Speaker 1: a lot of water. The average density of the human 764 00:44:16,640 --> 00:44:20,759 Speaker 1: body is very close to the density of water. I've 765 00:44:20,760 --> 00:44:24,960 Speaker 1: seen estimates that on average, a human adult with lungs 766 00:44:25,080 --> 00:44:28,120 Speaker 1: full of air is slightly less dense than water and 767 00:44:28,160 --> 00:44:31,760 Speaker 1: will float, and a human after exhaling with the lungs 768 00:44:31,800 --> 00:44:35,200 Speaker 1: empty is slightly more dense than water on average, or 769 00:44:35,680 --> 00:44:39,560 Speaker 1: roughly neutrally buoyant, and will more likely sink. And this 770 00:44:39,640 --> 00:44:43,520 Speaker 1: is going to vary somewhat due to tissue composition, clothing, 771 00:44:44,920 --> 00:44:47,520 Speaker 1: Literally how much gas you have in your digestive system 772 00:44:47,600 --> 00:44:51,120 Speaker 1: that plays a role in your natural buoyancy. But as 773 00:44:51,239 --> 00:44:55,640 Speaker 1: animals were naturally right around on the line between sinking 774 00:44:55,719 --> 00:44:58,440 Speaker 1: and floating, So if you just add a little bit 775 00:44:58,480 --> 00:45:02,040 Speaker 1: of extra low mass volume, like a life vest, it 776 00:45:02,080 --> 00:45:06,239 Speaker 1: pushes your volume to weight ratio over the line and 777 00:45:06,320 --> 00:45:08,880 Speaker 1: makes you a little more buoyant enough that your head 778 00:45:09,040 --> 00:45:12,280 Speaker 1: easily stays above the water, with most of your body 779 00:45:12,320 --> 00:45:15,520 Speaker 1: maybe neck down or shoulders down, displacing a lot of 780 00:45:15,600 --> 00:45:19,840 Speaker 1: water below the water line, but walking on top of 781 00:45:19,880 --> 00:45:23,759 Speaker 1: the water is a very different physical goal than just 782 00:45:23,840 --> 00:45:27,240 Speaker 1: keeping your head and its breathing holes above the water line. 783 00:45:27,520 --> 00:45:30,239 Speaker 1: To walk on top of the water, you would need 784 00:45:30,360 --> 00:45:35,240 Speaker 1: shoes that by themselves, just the shoe part, displace your 785 00:45:35,440 --> 00:45:39,040 Speaker 1: entire body's weight in water, which again means that the 786 00:45:39,040 --> 00:45:43,239 Speaker 1: shoes need to be both light or boat shaped in 787 00:45:43,280 --> 00:45:46,480 Speaker 1: a way with like a hollow hull and compared to 788 00:45:46,520 --> 00:45:51,080 Speaker 1: normal shoes huge. So it is not impossible to have 789 00:45:51,360 --> 00:45:53,600 Speaker 1: sort of shoes that will allow you to float on 790 00:45:53,600 --> 00:45:55,320 Speaker 1: the top of the water. You can look up videos 791 00:45:55,360 --> 00:45:58,080 Speaker 1: of people creating things like this, but again it's just 792 00:45:58,120 --> 00:46:01,920 Speaker 1: like people standing on too small boats. They're like big things, 793 00:46:01,960 --> 00:46:06,360 Speaker 1: they're not like shoes. The other issue is balance. You 794 00:46:06,440 --> 00:46:09,800 Speaker 1: brought this up rob Because of the low friction that 795 00:46:09,920 --> 00:46:13,720 Speaker 1: the interface between your water walking shoes and the water 796 00:46:13,880 --> 00:46:16,880 Speaker 1: as compared to shoes and the ground, it is difficult 797 00:46:16,920 --> 00:46:20,680 Speaker 1: to stay upright and propel yourself forward on a floatation device. 798 00:46:21,400 --> 00:46:24,840 Speaker 1: In videos like the MythBusters test, when people try to 799 00:46:24,880 --> 00:46:27,880 Speaker 1: do this, they quickly either sink or just tumble over. 800 00:46:28,640 --> 00:46:31,400 Speaker 3: Yeah, you end up falling one way, and say, like 801 00:46:31,400 --> 00:46:34,440 Speaker 3: the boogie board you're trying to balance on ends up 802 00:46:34,480 --> 00:46:36,439 Speaker 3: like soaring off the other way. 803 00:46:36,840 --> 00:46:42,080 Speaker 1: Yeah, so the mizogumo as shoes interpretation for walking on 804 00:46:42,520 --> 00:46:47,319 Speaker 1: actual water seems totally not plausible. However, a lot of 805 00:46:47,320 --> 00:46:51,360 Speaker 1: this gets cleared up with a reinterpretation of what this 806 00:46:51,520 --> 00:46:55,880 Speaker 1: device was intended to be used for. So the original 807 00:46:55,960 --> 00:47:00,600 Speaker 1: text that describes this device does not describe about how 808 00:47:00,719 --> 00:47:04,799 Speaker 1: it's used. It only sort of give give specifications of 809 00:47:04,840 --> 00:47:08,160 Speaker 1: the device itself and shows an illustration of a single 810 00:47:08,200 --> 00:47:12,480 Speaker 1: one in isolation, notably not a pair of them. Also, 811 00:47:12,560 --> 00:47:16,240 Speaker 1: the original illustration does not indicate any kind of sandal 812 00:47:16,320 --> 00:47:19,840 Speaker 1: strap or other way of attaching the paddle in the 813 00:47:19,880 --> 00:47:23,840 Speaker 1: middle of the disk to one's foot. So some modern 814 00:47:23,880 --> 00:47:26,319 Speaker 1: scholars have come to think that this device was not 815 00:47:26,520 --> 00:47:31,600 Speaker 1: actually intended to be used in pairs as footwear, but 816 00:47:31,760 --> 00:47:36,560 Speaker 1: instead was a seat used for floatation in the water. 817 00:47:36,960 --> 00:47:41,799 Speaker 1: So a ninja could, according to this interpretation, sit in 818 00:47:41,880 --> 00:47:44,000 Speaker 1: this sort of ring and use it like an inner 819 00:47:44,040 --> 00:47:47,960 Speaker 1: tube and then float across a water remote but they 820 00:47:48,000 --> 00:47:50,640 Speaker 1: absolutely would get wet if they did this. They would 821 00:47:50,680 --> 00:47:53,200 Speaker 1: be sitting in the water, but the upper part of 822 00:47:53,239 --> 00:47:55,560 Speaker 1: their body would be sitting above the water like sitting 823 00:47:55,600 --> 00:47:56,480 Speaker 1: in an inner tube. 824 00:47:56,760 --> 00:47:58,520 Speaker 3: So you might want to, like take your pants off, 825 00:47:59,600 --> 00:48:03,880 Speaker 3: you an pants in your pack until you get across, 826 00:48:04,400 --> 00:48:06,440 Speaker 3: climb up half naked, and then put your pants back 827 00:48:06,440 --> 00:48:07,479 Speaker 3: on right. 828 00:48:07,560 --> 00:48:10,359 Speaker 1: And of course all of the caveats and uncertainties about 829 00:48:10,440 --> 00:48:12,880 Speaker 1: hystericity remain. We don't know if this was ever like 830 00:48:13,160 --> 00:48:15,680 Speaker 1: really used, or if it was exactly what it was 831 00:48:15,800 --> 00:48:20,839 Speaker 1: used for. I've seen speculation that seems again just total speculation, 832 00:48:21,000 --> 00:48:24,640 Speaker 1: that you could, like, oh, you could transport gunpowder across 833 00:48:24,680 --> 00:48:27,040 Speaker 1: the water without getting it wet by using one of these. 834 00:48:27,080 --> 00:48:28,520 Speaker 1: You know, you could hold it up in the air 835 00:48:28,600 --> 00:48:31,759 Speaker 1: and float across the water. I guess you could do that, 836 00:48:31,840 --> 00:48:34,279 Speaker 1: But then again, you could also probably just use like 837 00:48:34,320 --> 00:48:38,239 Speaker 1: a small raft or boat. So I don't think it's 838 00:48:38,239 --> 00:48:44,959 Speaker 1: fully understood what the alleged benefit of this device as 839 00:48:45,000 --> 00:48:47,799 Speaker 1: described would be. But it does seem to me that 840 00:48:47,880 --> 00:48:52,480 Speaker 1: the floating seat interpretation is more likely what the author 841 00:48:52,520 --> 00:48:55,520 Speaker 1: intended than the footwear and interpretation. 842 00:48:56,160 --> 00:48:59,160 Speaker 3: I mean, we mentioned that it's important for a shnobi 843 00:48:59,200 --> 00:49:03,080 Speaker 3: operative to potentially become part of the community open up 844 00:49:03,080 --> 00:49:07,320 Speaker 3: a business. What if that business was essentially tubing, providing 845 00:49:07,680 --> 00:49:12,000 Speaker 3: inflatable circular devices for tourists to float from point a 846 00:49:12,080 --> 00:49:14,920 Speaker 3: to point B down a river, you know, at leisure, 847 00:49:15,280 --> 00:49:18,000 Speaker 3: perhaps while enjoying a beverage. It might give you the 848 00:49:18,040 --> 00:49:18,640 Speaker 3: cover you need. 849 00:49:19,480 --> 00:49:22,239 Speaker 1: Okay, well, maybe we have to call it for part 850 00:49:22,360 --> 00:49:25,960 Speaker 1: three here, but we've got more alleged ninja techniques and 851 00:49:26,080 --> 00:49:28,600 Speaker 1: anecdotes to talk about in the next episode. 852 00:49:28,840 --> 00:49:31,279 Speaker 3: That's right, we'll be back and we'll cover We'll cover 853 00:49:31,680 --> 00:49:34,160 Speaker 3: some big ones.
