1 00:00:03,080 --> 00:00:07,080 Speaker 1: Welcome to Stuff to Blow Your Mind, production of iHeartRadio. 2 00:00:12,840 --> 00:00:15,239 Speaker 2: Hey, welcome to Stuff to Blow Your Mind. My name 3 00:00:15,280 --> 00:00:16,440 Speaker 2: is Robert Lamb. 4 00:00:16,280 --> 00:00:19,000 Speaker 3: And I'm Joe McCormick, and we're back with part three 5 00:00:19,160 --> 00:00:23,000 Speaker 3: in our series on Ninja. Now, if you haven't heard 6 00:00:23,120 --> 00:00:25,439 Speaker 3: the first two parts of this series, this is a 7 00:00:25,480 --> 00:00:27,840 Speaker 3: case where you really should go back and listen to 8 00:00:27,880 --> 00:00:30,400 Speaker 3: those before you listen to today's episode, because we lay 9 00:00:30,440 --> 00:00:35,480 Speaker 3: a lot of groundwork, especially about the tricky historical questions 10 00:00:35,800 --> 00:00:39,519 Speaker 3: about the sort of accuracy of a lot of the 11 00:00:39,560 --> 00:00:43,200 Speaker 3: received knowledge about the ninja. And so if you are 12 00:00:43,440 --> 00:00:46,839 Speaker 3: wondering about like how the ninja fit into real history 13 00:00:47,040 --> 00:00:52,080 Speaker 3: versus pop culture and then sort of subsequent lore and legend, 14 00:00:52,560 --> 00:00:55,320 Speaker 3: we talk more about that in the previous episodes. Today 15 00:00:55,320 --> 00:00:57,720 Speaker 3: we're going to be focusing more on just some of 16 00:00:57,760 --> 00:01:01,720 Speaker 3: the great bits of tech mixture and the anecdotes from 17 00:01:01,720 --> 00:01:06,080 Speaker 3: that historical lore and legend, the stories of individual ninjas, 18 00:01:06,680 --> 00:01:10,120 Speaker 3: the stories of the stories of tools and techniques and 19 00:01:10,160 --> 00:01:11,520 Speaker 3: equipment and so forth. 20 00:01:12,040 --> 00:01:14,440 Speaker 2: Yeah, I mean, you basically can think of it this way. 21 00:01:15,200 --> 00:01:19,440 Speaker 2: The ninja existed, true statement, the ninja are a myth 22 00:01:19,480 --> 00:01:22,400 Speaker 2: and never existed. True statement depends on how you tease 23 00:01:22,400 --> 00:01:25,280 Speaker 2: it apart, you know, and likewise a lot of this too, 24 00:01:25,360 --> 00:01:29,400 Speaker 2: Like we'll get into specific examples of ninja tools or weapons, 25 00:01:29,400 --> 00:01:32,120 Speaker 2: and you can say this never existed, and then you 26 00:01:32,160 --> 00:01:34,679 Speaker 2: can also say, but I can buy one at the 27 00:01:34,760 --> 00:01:38,119 Speaker 2: mall today, and so it's like, well it exists now, right, 28 00:01:38,240 --> 00:01:40,000 Speaker 2: So it's it gets complicated. 29 00:01:40,480 --> 00:01:42,880 Speaker 3: This is a great time, I think, to discuss some 30 00:01:43,000 --> 00:01:47,039 Speaker 3: of the various ninjutsu manuals that were published beginning in 31 00:01:47,120 --> 00:01:52,600 Speaker 3: the Edo period, beginning under the Tokugawa Shogunate, that are 32 00:01:52,680 --> 00:01:56,360 Speaker 3: the source of a lot of the ninja lore that 33 00:01:56,440 --> 00:01:58,400 Speaker 3: we have today. So you can think about sort of 34 00:01:58,440 --> 00:02:02,520 Speaker 3: like multiple stages of development of the ninja lore over 35 00:02:02,560 --> 00:02:07,240 Speaker 3: the centuries. This is going way back. It's questionable whether 36 00:02:07,360 --> 00:02:10,519 Speaker 3: some of the things reported in these manuals were actually 37 00:02:10,680 --> 00:02:15,600 Speaker 3: used in the earlier periods, But these seventeenth eighteenth century 38 00:02:15,639 --> 00:02:19,160 Speaker 3: texts have lots of great stuff in them that I 39 00:02:19,160 --> 00:02:22,880 Speaker 3: think later gets picked up by authors, say in the 40 00:02:22,919 --> 00:02:27,720 Speaker 3: twentieth century, and reprocessed and turned into the pop culture 41 00:02:27,760 --> 00:02:31,880 Speaker 3: idea of the ninja. So there are multiple ninjitsu manuals, 42 00:02:32,040 --> 00:02:36,520 Speaker 3: and I'm just going to list some common characteristics of them. 43 00:02:37,000 --> 00:02:42,600 Speaker 3: So they will teach techniques of espionage, stealth, and intelligence gathering, 44 00:02:43,000 --> 00:02:46,600 Speaker 3: including everything from how to infiltrate a building using different 45 00:02:46,639 --> 00:02:49,880 Speaker 3: kinds of ladders to how to gag a prisoner. So 46 00:02:50,160 --> 00:02:54,720 Speaker 3: they're full of descriptions of techniques. They pass along practical 47 00:02:54,760 --> 00:02:58,680 Speaker 3: knowledge about real subjects, such as pharmacology like using herbs 48 00:02:58,720 --> 00:03:01,360 Speaker 3: to achieve an effect in the body, and how to 49 00:03:01,440 --> 00:03:05,240 Speaker 3: use gunpowders, so there is some amount of chemistry knowledge, 50 00:03:05,240 --> 00:03:08,160 Speaker 3: at least as it was understood in the seventeenth century. 51 00:03:08,200 --> 00:03:11,720 Speaker 3: In some of these books, they describe and illustrate tools 52 00:03:11,720 --> 00:03:15,799 Speaker 3: and equipment such as cow drops. You know, these spiked 53 00:03:16,000 --> 00:03:19,079 Speaker 3: spiked objects that would be used. You know, you'd throw 54 00:03:19,120 --> 00:03:21,200 Speaker 3: them on the ground to slow the advance of an 55 00:03:21,320 --> 00:03:23,480 Speaker 3: enemy or to deny them access to an area. 56 00:03:23,760 --> 00:03:26,799 Speaker 2: Yeah, makabishi, I believe, is the term for these. And 57 00:03:27,600 --> 00:03:30,639 Speaker 2: these are interesting on their own terms because if you've 58 00:03:30,639 --> 00:03:32,640 Speaker 2: played Dungeons and Dragons, you may have used these. You know, 59 00:03:32,680 --> 00:03:35,560 Speaker 2: these are pretty common way to slow down an enemy. 60 00:03:36,840 --> 00:03:40,440 Speaker 2: But apparently when you get into the history of their 61 00:03:40,560 --> 00:03:45,000 Speaker 2: use in shnobi activities, like some examples of them may 62 00:03:45,040 --> 00:03:48,680 Speaker 2: have been essentially organic or found items like essentially like 63 00:03:48,760 --> 00:03:52,480 Speaker 2: throwing nuts, you know, or today's version would be like 64 00:03:52,520 --> 00:03:56,000 Speaker 2: spreading legos all over the floor. That's not quite like 65 00:03:56,000 --> 00:03:57,840 Speaker 2: a nature fact or a found item, but you know, 66 00:03:57,880 --> 00:03:59,720 Speaker 2: you get the idea and then that you could progress 67 00:03:59,720 --> 00:04:03,560 Speaker 2: from them into potentially like metal objects that are spiked 68 00:04:03,560 --> 00:04:06,920 Speaker 2: and so forth. And speaking of those ladders, yes, ladders 69 00:04:06,920 --> 00:04:09,760 Speaker 2: are absolutely a tool of the ninja. And if you 70 00:04:09,800 --> 00:04:12,080 Speaker 2: are in the Dungeons and Dragons campaign and you're playing 71 00:04:12,080 --> 00:04:14,720 Speaker 2: a rogue, go ahead and equip that ladder, bring that 72 00:04:14,800 --> 00:04:17,200 Speaker 2: ladder with you, and dare your dungeon master to make 73 00:04:17,200 --> 00:04:20,640 Speaker 2: you roll a dexterity check whilst climbing it. Ladders are great, 74 00:04:21,080 --> 00:04:22,160 Speaker 2: trust the ninja on this. 75 00:04:23,200 --> 00:04:25,920 Speaker 3: My current rogue has a real affinity for climbing. He's 76 00:04:25,960 --> 00:04:28,280 Speaker 3: got the I don't know it's level three or level 77 00:04:28,279 --> 00:04:29,960 Speaker 3: four or wherever it is. You get to pick one 78 00:04:29,960 --> 00:04:32,560 Speaker 3: of the feats, and he's got second story work where 79 00:04:32,600 --> 00:04:34,799 Speaker 3: you know, you can climb at the same rate you 80 00:04:34,480 --> 00:04:35,400 Speaker 3: can you can run. 81 00:04:35,680 --> 00:04:38,080 Speaker 2: That's great. Yeah, but I feel like we've been kind 82 00:04:38,080 --> 00:04:41,960 Speaker 2: of just like a modern Ninja batmanification of our understanding 83 00:04:42,000 --> 00:04:44,880 Speaker 2: of what rogues should have. Batman never carried a ladder 84 00:04:44,880 --> 00:04:46,480 Speaker 2: but he probably should have carried a ladder. I think 85 00:04:46,480 --> 00:04:47,039 Speaker 2: that would be great. 86 00:04:47,040 --> 00:04:49,440 Speaker 3: The bat ladder, I mean, the rope ladder, will you 87 00:04:49,560 --> 00:04:51,360 Speaker 3: gets you a lot of places. I guess batman doesn't 88 00:04:51,360 --> 00:04:53,960 Speaker 3: need a ladder because he has the unrealistic, the back 89 00:04:54,040 --> 00:04:56,240 Speaker 3: claw thing that you can just shoot and will zip 90 00:04:56,279 --> 00:04:57,040 Speaker 3: him up anywhere. 91 00:04:57,320 --> 00:05:01,520 Speaker 2: Absolute trust in the masonry the buildings he's interacting with. 92 00:05:01,960 --> 00:05:05,320 Speaker 3: Yeah, but anyway, all the stuff I've mentioned so far, 93 00:05:06,000 --> 00:05:09,560 Speaker 3: that's the stuff you would imagine a ninjitsu manual to include. Right, 94 00:05:09,600 --> 00:05:14,960 Speaker 3: you know, techniques about stealth tools. You could use, knowledge 95 00:05:14,960 --> 00:05:18,520 Speaker 3: about pharmacology and gunpowder and things like that. But there 96 00:05:18,520 --> 00:05:22,599 Speaker 3: are also things you might expect less. These manuals often 97 00:05:22,800 --> 00:05:27,680 Speaker 3: emphasize spiritual and philosophical elements of the shnobi lifestyle, like 98 00:05:27,920 --> 00:05:31,159 Speaker 3: some during the Edo period promote Confucianism with a strong 99 00:05:31,240 --> 00:05:34,080 Speaker 3: emphasis on loyalty, which of course was favored by the 100 00:05:34,360 --> 00:05:40,120 Speaker 3: Tokugawa shoguns. They sometimes also include moral discourses that serve 101 00:05:40,240 --> 00:05:44,760 Speaker 3: as justification for shnobi activities, like it's okay to use 102 00:05:44,880 --> 00:05:48,440 Speaker 3: lies and deception and trickery because they will help you win. 103 00:05:48,640 --> 00:05:50,720 Speaker 3: They're what you have to do to win, and what's 104 00:05:50,760 --> 00:05:53,920 Speaker 3: ultimately right is to be loyal to your masters and 105 00:05:54,000 --> 00:05:57,919 Speaker 3: to help win in the conflict. And so so you know, 106 00:05:57,960 --> 00:06:00,320 Speaker 3: you got to deliver that intelligence. It doesn't matter if 107 00:06:00,360 --> 00:06:03,000 Speaker 3: you have to lie to do it. They sometimes also 108 00:06:03,000 --> 00:06:07,920 Speaker 3: include more esoteric guidance, like the use of astrology or divination. 109 00:06:09,440 --> 00:06:13,240 Speaker 3: They are often falsely attributed to a great hero or 110 00:06:13,360 --> 00:06:18,200 Speaker 3: legend from history. They do not depict shnobi in black 111 00:06:18,279 --> 00:06:23,440 Speaker 3: costumes and masks. They are not generally concerned with assassination, 112 00:06:23,920 --> 00:06:27,440 Speaker 3: nor do they usually describe hand to hand combat or 113 00:06:27,480 --> 00:06:30,359 Speaker 3: sword fighting techniques, as would come to be the calling 114 00:06:30,400 --> 00:06:34,479 Speaker 3: card of Ninja in later movies. Once again, they are 115 00:06:34,720 --> 00:06:40,039 Speaker 3: most often concerned with intelligence gathering, psychological warfare, and sabotage. 116 00:06:40,520 --> 00:06:42,480 Speaker 3: And to this point, one of the manuals I'll mention 117 00:06:42,640 --> 00:06:45,920 Speaker 3: in a minute actually specifies that your shinobi your spies 118 00:06:46,080 --> 00:06:50,640 Speaker 3: should be selected based on intelligence and not physical strength, 119 00:06:51,080 --> 00:06:54,919 Speaker 3: because these people were not primarily thought of as fighters, 120 00:06:55,040 --> 00:06:58,599 Speaker 3: but as tricksters and observers gatherers of information. 121 00:06:59,200 --> 00:07:02,799 Speaker 2: Yeah, I mean, when you think about it, like your shnobi, 122 00:07:03,000 --> 00:07:04,719 Speaker 2: are they going to be able to throw down with 123 00:07:04,760 --> 00:07:08,640 Speaker 2: a samurai, an armed samurai like you know, one to 124 00:07:08,720 --> 00:07:11,880 Speaker 2: one in some sort of a battle. I think there's 125 00:07:11,920 --> 00:07:15,040 Speaker 2: a strong case to be made. No, the trickery if that, 126 00:07:15,240 --> 00:07:18,560 Speaker 2: if that's sort of violent encounter where to occur, the 127 00:07:18,560 --> 00:07:22,120 Speaker 2: trickery is going to make the difference, not the martial arts. 128 00:07:22,160 --> 00:07:23,480 Speaker 2: I'm guessing that's right. 129 00:07:23,480 --> 00:07:25,400 Speaker 3: As we talked about in the last episode, the idea 130 00:07:25,480 --> 00:07:30,560 Speaker 3: of shanoby as instigators of daring individual violence and hand 131 00:07:30,560 --> 00:07:33,840 Speaker 3: to hand combat, that is more of the later movie 132 00:07:33,920 --> 00:07:37,200 Speaker 3: ninja thing. The earlier emphasis is though there all there 133 00:07:37,240 --> 00:07:41,160 Speaker 3: are lots of sort of shinobi warfare activities in shnobi attacks, 134 00:07:41,200 --> 00:07:44,640 Speaker 3: sneak attacks by night. Most of the time, these manuals 135 00:07:44,640 --> 00:07:49,160 Speaker 3: and early ideas of shinobi are are more focused on spying. 136 00:07:49,800 --> 00:07:53,400 Speaker 3: For just one example of how these older military manuals 137 00:07:53,480 --> 00:07:57,880 Speaker 3: might focus more on espionage strategy than on the type 138 00:07:57,880 --> 00:08:01,880 Speaker 3: of combat focused ninja behavior we think of today, there 139 00:08:02,040 --> 00:08:06,560 Speaker 3: was a sixteenth century military manual called the Kinetsushu, and 140 00:08:06,760 --> 00:08:10,440 Speaker 3: this text was from earlier than the major ninjutsu manual. 141 00:08:10,520 --> 00:08:12,080 Speaker 3: So this is not I want to be clear, this 142 00:08:12,120 --> 00:08:14,560 Speaker 3: is not one of the ninjutsu manuals I'm talking about. 143 00:08:14,600 --> 00:08:18,320 Speaker 3: This is a general warfare manual from a little bit earlier, 144 00:08:18,360 --> 00:08:22,520 Speaker 3: and its focus is broadly on strategy and warfare, but 145 00:08:22,600 --> 00:08:26,840 Speaker 3: it contains a sub section on espionage techniques, and it 146 00:08:26,920 --> 00:08:29,360 Speaker 3: recommends things like the following. It says, before you go 147 00:08:29,360 --> 00:08:33,240 Speaker 3: on a military campaign, send spies into the area that 148 00:08:33,280 --> 00:08:38,080 Speaker 3: you're targeting to pose as merchants and craftsmen. And these 149 00:08:38,120 --> 00:08:41,720 Speaker 3: spies should make maps of local topography and try to 150 00:08:41,800 --> 00:08:45,240 Speaker 3: figure out the morale of locals, for example, by listening 151 00:08:45,320 --> 00:08:48,920 Speaker 3: to whether people sing sad songs or happy songs. And 152 00:08:49,000 --> 00:08:52,120 Speaker 3: you can also try to split loyalties within the region 153 00:08:52,600 --> 00:08:55,800 Speaker 3: by doing things like have your spies make donations to 154 00:08:55,880 --> 00:08:58,960 Speaker 3: local temples and shrines to win over the approval of 155 00:08:59,000 --> 00:08:59,920 Speaker 3: the priests class. 156 00:09:00,520 --> 00:09:02,560 Speaker 2: And I'm guessing you had to be kind of selective 157 00:09:02,600 --> 00:09:04,800 Speaker 2: about how you do it, Like, don't immediately set up 158 00:09:04,840 --> 00:09:06,839 Speaker 2: shop and be like, hey, what do you think of 159 00:09:06,880 --> 00:09:11,120 Speaker 2: the latest Lena del Rey album. You know, tease it 160 00:09:11,160 --> 00:09:13,080 Speaker 2: out a little bit, make sure you have enough lead 161 00:09:13,160 --> 00:09:18,079 Speaker 2: time to really immerse yourself in the local community. 162 00:09:18,440 --> 00:09:20,600 Speaker 3: Exactly right. Oh, and I should say, by the way, 163 00:09:20,640 --> 00:09:22,440 Speaker 3: I mentioned it in the last couple of episodes, but 164 00:09:22,520 --> 00:09:24,640 Speaker 3: just to flag again one of my major sources here. 165 00:09:25,120 --> 00:09:29,240 Speaker 3: Also on the general facts about these ninjasu manuals is 166 00:09:29,360 --> 00:09:32,720 Speaker 3: a book by a British historian named Stephen Turnbull called 167 00:09:32,840 --> 00:09:36,400 Speaker 3: Ninja Unmasking the Myth from twenty seventeen, and so he 168 00:09:36,520 --> 00:09:40,679 Speaker 3: highlights several important ninjasu manuals that I wanted to talk 169 00:09:40,720 --> 00:09:43,760 Speaker 3: about for a moment here. These later manuals in the 170 00:09:43,800 --> 00:09:48,520 Speaker 3: seventeenth century onward were more directly focused on ninjitsu, and 171 00:09:48,559 --> 00:09:53,079 Speaker 3: they include texts such as the Gunpo Geoshu, which was 172 00:09:53,120 --> 00:09:57,280 Speaker 3: published in the sixteen fifties, and the famous mansen shu 173 00:09:57,400 --> 00:10:01,600 Speaker 3: Kai or benson Shukai from around sixteen seventy six, the 174 00:10:01,679 --> 00:10:04,800 Speaker 3: latter of which has in some instances been referred to 175 00:10:04,920 --> 00:10:08,360 Speaker 3: as the Ninja Bible, though this is probably a misleading 176 00:10:08,400 --> 00:10:13,080 Speaker 3: way to characterize it. Mens In Chuki or bens in Chukai. 177 00:10:13,400 --> 00:10:17,199 Speaker 3: The title means ten thousand rivers flowing together into an ocean, 178 00:10:18,000 --> 00:10:21,200 Speaker 3: and in particular this one is the source of a 179 00:10:21,320 --> 00:10:25,680 Speaker 3: lot of modern ninja lore. It contains details about ingenious 180 00:10:25,800 --> 00:10:30,480 Speaker 3: ninja gadgets and equipment. It also contains different philosophies about 181 00:10:30,520 --> 00:10:34,520 Speaker 3: spying and infiltration. It makes an interesting distinction between what 182 00:10:34,559 --> 00:10:39,200 Speaker 3: it calls yonin and enin yonin meaning open infiltration, So 183 00:10:39,200 --> 00:10:42,880 Speaker 3: this would be sneaking into somewhere by wearing a disguise, 184 00:10:43,120 --> 00:10:46,240 Speaker 3: or being accepted by the target community, so you are 185 00:10:46,640 --> 00:10:52,200 Speaker 3: within view, but you are disguising your intentions in some way. Meanwhile, 186 00:10:52,360 --> 00:10:56,120 Speaker 3: en means invisibility or hiding, so this would be infiltration 187 00:10:56,240 --> 00:10:59,320 Speaker 3: by sneaking by night or hiding under floorboards. 188 00:11:00,120 --> 00:11:02,120 Speaker 2: And that's where we get into some of these the 189 00:11:02,160 --> 00:11:06,640 Speaker 2: elements of patients and endurance that we mentioned in the 190 00:11:06,679 --> 00:11:09,160 Speaker 2: last episode. I believe like if you're going to have 191 00:11:09,160 --> 00:11:12,400 Speaker 2: to hide under the floorboards for let's say forty eight hours, 192 00:11:13,120 --> 00:11:16,520 Speaker 2: you know you're going to have to use some schanobi patients. 193 00:11:16,920 --> 00:11:17,400 Speaker 2: That's right. 194 00:11:17,480 --> 00:11:19,520 Speaker 3: And that's one reason that there may not be as 195 00:11:19,720 --> 00:11:25,000 Speaker 3: much difference between the idea of practicing endurance or patients 196 00:11:25,040 --> 00:11:28,360 Speaker 3: and practicing stealth as you might originally think, like a 197 00:11:28,360 --> 00:11:31,520 Speaker 3: lot of stealth is patience. In fact, you could even 198 00:11:31,600 --> 00:11:34,160 Speaker 3: argue that the patience is very important when you are 199 00:11:34,240 --> 00:11:38,000 Speaker 3: just being accepted within a target community or in disguise. Right, 200 00:11:38,040 --> 00:11:39,920 Speaker 3: you've got to play the part for a long time 201 00:11:40,000 --> 00:11:41,520 Speaker 3: to sort of make people comfortable. 202 00:11:41,840 --> 00:11:44,240 Speaker 2: Yeah, yeah, you got to actually run that business, Like, 203 00:11:45,160 --> 00:11:48,199 Speaker 2: don't offer like really deep discounts. They're going to be suspicious. 204 00:11:48,600 --> 00:11:50,840 Speaker 2: Don't act like you're not interested in making a profit 205 00:11:50,880 --> 00:11:53,640 Speaker 2: one way or the other. Yeah, become a part of 206 00:11:53,640 --> 00:11:55,320 Speaker 2: the community and then betray them. 207 00:11:55,720 --> 00:11:59,360 Speaker 3: Another interesting thing about these ninjitsu manuals is the thing 208 00:11:59,360 --> 00:12:03,960 Speaker 3: that makes them really tempting to interpret is that sometimes 209 00:12:04,000 --> 00:12:08,199 Speaker 3: they might include explanations and references that seem kind of circumspect, 210 00:12:08,320 --> 00:12:10,440 Speaker 3: like they don't give all the details of what they're 211 00:12:10,480 --> 00:12:13,240 Speaker 3: talking about. And then sometimes they'll have a note like 212 00:12:13,559 --> 00:12:16,440 Speaker 3: additional information is only to be passed on by word 213 00:12:16,480 --> 00:12:16,920 Speaker 3: of mouth. 214 00:12:17,280 --> 00:12:21,000 Speaker 2: Oh boy, that sounds very shanobi. 215 00:12:21,320 --> 00:12:24,400 Speaker 3: Yeah. One random detail that I love, by the way, 216 00:12:24,559 --> 00:12:27,320 Speaker 3: just came across this in the book. This is about 217 00:12:27,360 --> 00:12:32,080 Speaker 3: the gun pogoshu. It's the claim that in the ancient past, 218 00:12:32,280 --> 00:12:35,880 Speaker 3: men of the regions Ega and Coca, which are places 219 00:12:35,880 --> 00:12:39,360 Speaker 3: in Japan that are they have long been claimed as 220 00:12:39,480 --> 00:12:43,240 Speaker 3: national headquarters of shnobi training. So the claim is that 221 00:12:43,280 --> 00:12:46,920 Speaker 3: these these ninja from Ega and Coca would travel as 222 00:12:47,120 --> 00:12:52,000 Speaker 3: secret agents, and while doing so, they would pose as yamabushi, 223 00:12:52,160 --> 00:12:56,960 Speaker 3: which means street performers such as monkey tamers. So like 224 00:12:57,080 --> 00:12:59,040 Speaker 3: the next time you see a busker playing a Goo 225 00:12:59,040 --> 00:13:01,160 Speaker 3: Goo Dolls song on the sidewalk, or you see a 226 00:13:01,160 --> 00:13:04,160 Speaker 3: guy dressed up as Superman in Times Square, you might 227 00:13:04,240 --> 00:13:07,480 Speaker 3: wonder is this a ninja? Is this person gathering intelligence? 228 00:13:08,679 --> 00:13:12,720 Speaker 3: Another interesting fact about the gun Pogoshu in particular is 229 00:13:12,760 --> 00:13:15,560 Speaker 3: that some of its espionage advice is given in the 230 00:13:15,600 --> 00:13:18,640 Speaker 3: form of a collection of poems, poems about spying. 231 00:13:19,320 --> 00:13:22,520 Speaker 2: Wow. Wow, that's fascinating that. Yeah, this goes hand in 232 00:13:22,559 --> 00:13:24,280 Speaker 2: hand with some of the things we've been talking about 233 00:13:24,320 --> 00:13:28,920 Speaker 2: about disguising yourself blending in. But I guess sometimes like 234 00:13:29,040 --> 00:13:32,560 Speaker 2: being the obnoxiously obvious person is also a way of 235 00:13:32,559 --> 00:13:36,040 Speaker 2: blending into the background, Like nobody suspects the like the 236 00:13:36,080 --> 00:13:38,800 Speaker 2: Time Square Elmo of Well, you may suspect the Times 237 00:13:38,800 --> 00:13:42,680 Speaker 2: Square Elmo of things, but probably not espionage, right. 238 00:13:42,920 --> 00:13:56,040 Speaker 3: Exactly anyway, So, with all the caveats we've previously established 239 00:13:56,080 --> 00:13:59,680 Speaker 3: about the historicity of what's in these manuals that, you know, 240 00:13:59,720 --> 00:14:03,520 Speaker 3: we might regard them with some historical skepticism. Nevertheless, they 241 00:14:03,559 --> 00:14:07,760 Speaker 3: do describe a lot of fascinating alleged tricks and tools 242 00:14:07,800 --> 00:14:11,559 Speaker 3: of ninjasu. So I think we should just dive right 243 00:14:11,600 --> 00:14:14,359 Speaker 3: in and talk about some alleged ninja techniques. 244 00:14:14,720 --> 00:14:16,280 Speaker 2: Yeah, I want to pick up talking a little a 245 00:14:16,280 --> 00:14:20,440 Speaker 2: bit about the female shanobi or the kuno ichi, which 246 00:14:20,480 --> 00:14:22,960 Speaker 2: I believe we mentioned in passing in the first episode. 247 00:14:23,360 --> 00:14:25,480 Speaker 2: You know, the idea that we could have have both 248 00:14:25,480 --> 00:14:31,000 Speaker 2: male and female ninja, and this does really stress the 249 00:14:31,000 --> 00:14:36,520 Speaker 2: the reality that that that shinobi activities would have covered 250 00:14:36,560 --> 00:14:39,680 Speaker 2: a lot of ground that isn't just concerned with assassination 251 00:14:40,080 --> 00:14:43,640 Speaker 2: or military and military and you know, direct military adjacent 252 00:14:43,640 --> 00:14:46,960 Speaker 2: combat adjacent activities, but get into all these areas of spycraft. 253 00:14:47,720 --> 00:14:51,240 Speaker 2: And there is apparently, according to Yoda and Alt in 254 00:14:51,400 --> 00:14:53,760 Speaker 2: their book on Ninja's that I that I cited in 255 00:14:53,800 --> 00:14:58,160 Speaker 2: the previous episodes, there's no evidence that female shanobi ever 256 00:14:58,280 --> 00:15:02,240 Speaker 2: engaged in combat, though of course there are historic examples 257 00:15:02,280 --> 00:15:06,200 Speaker 2: of Japanese women serving as warriors, such as tome Gozen 258 00:15:06,480 --> 00:15:09,600 Speaker 2: of the late twelfth century. So again not saying they 259 00:15:09,600 --> 00:15:13,880 Speaker 2: weren't female warriors in Japanese history, and even that there 260 00:15:13,920 --> 00:15:18,240 Speaker 2: weren't female shannoby operatives who engaged in combat, but there's 261 00:15:18,240 --> 00:15:23,880 Speaker 2: no evidence of such, but there are writings about female 262 00:15:24,000 --> 00:15:28,120 Speaker 2: shinobi operatives, and this makes sense for reasons we already 263 00:15:28,120 --> 00:15:30,840 Speaker 2: stress like if you were going to engage in spycraft, 264 00:15:31,240 --> 00:15:34,320 Speaker 2: you're you're going to take advantage of whatever tools are 265 00:15:34,320 --> 00:15:36,200 Speaker 2: at your disposal. And there are going to be certain 266 00:15:36,720 --> 00:15:40,720 Speaker 2: segments of society through which females are going to be 267 00:15:40,720 --> 00:15:42,760 Speaker 2: able to travel with a little more ease or a 268 00:15:42,760 --> 00:15:47,520 Speaker 2: little less notice and there, and as we mentioned last time, 269 00:15:47,560 --> 00:15:52,800 Speaker 2: there is at least one named female ninja Mochizuki chi Yojo, 270 00:15:53,160 --> 00:15:56,760 Speaker 2: and this individual is still somewhat of a mystery. There 271 00:15:56,800 --> 00:15:59,760 Speaker 2: are some arguments that she didn't exist at all, but 272 00:16:00,160 --> 00:16:03,720 Speaker 2: to an all lister existence as confirmed, so I guess 273 00:16:03,720 --> 00:16:06,600 Speaker 2: there is a certain amount of evidence on one side 274 00:16:06,600 --> 00:16:08,960 Speaker 2: of the argument to say that this person did exist 275 00:16:09,040 --> 00:16:12,800 Speaker 2: in some form. Assuming she did exist, however, she would 276 00:16:12,840 --> 00:16:15,800 Speaker 2: have been like a poet, a noble woman, and it's 277 00:16:15,960 --> 00:16:19,320 Speaker 2: said that she was affiliated with the Takata samurai clan 278 00:16:19,440 --> 00:16:22,480 Speaker 2: and to have presided over a team of the uruki 279 00:16:22,520 --> 00:16:25,240 Speaker 2: miko or walking maidens, so she would have kind of 280 00:16:25,320 --> 00:16:29,320 Speaker 2: like been a spymaster of female shanobi and so on 281 00:16:29,360 --> 00:16:31,720 Speaker 2: the realistic end of things. If there's truth to any 282 00:16:31,800 --> 00:16:34,640 Speaker 2: of this, whether we were dealing with the specifics of 283 00:16:34,680 --> 00:16:37,440 Speaker 2: this individual or just the general idea that there were 284 00:16:37,680 --> 00:16:42,360 Speaker 2: female spy operatives in Japan during the Warring States period, 285 00:16:42,400 --> 00:16:45,680 Speaker 2: just as there have been female spy operatives in pretty 286 00:16:45,720 --> 00:16:47,600 Speaker 2: much every culture. I think every culture, I think we're 287 00:16:47,600 --> 00:16:50,840 Speaker 2: going to be a safe assumption these would have been 288 00:16:51,880 --> 00:16:56,840 Speaker 2: female operatives who could travel around, often as Shinto holy women, 289 00:16:57,360 --> 00:17:02,560 Speaker 2: as entertainers, or perhaps prostitutots. Now on the legendary end 290 00:17:02,600 --> 00:17:06,159 Speaker 2: of the spectrum, however, female shenobi were often imbued with 291 00:17:06,280 --> 00:17:10,160 Speaker 2: various powers that were linked to female sexuality and reproduction, 292 00:17:10,320 --> 00:17:12,919 Speaker 2: and a lot of this has much in common with 293 00:17:13,080 --> 00:17:16,560 Speaker 2: various witchlike belief systems from around the world, you know, 294 00:17:16,640 --> 00:17:20,679 Speaker 2: even getting into ideas of like the monstrous feminine, you know, 295 00:17:20,760 --> 00:17:23,760 Speaker 2: the the other ing of of the female and taking 296 00:17:23,800 --> 00:17:27,600 Speaker 2: aspects of reproduction and sexuality and tweaking them into the 297 00:17:27,880 --> 00:17:32,040 Speaker 2: you know, the demonic realm and so forth. But this 298 00:17:32,119 --> 00:17:34,800 Speaker 2: also put me very much in mind of the benajesrit 299 00:17:34,880 --> 00:17:39,000 Speaker 2: from Frank Herbert's done as well as their later series counterparts, 300 00:17:39,640 --> 00:17:43,359 Speaker 2: the Honored Matre, were kind of like a splinter of 301 00:17:43,400 --> 00:17:46,840 Speaker 2: the benajestert who are their opposition. So I wanted to 302 00:17:46,920 --> 00:17:50,080 Speaker 2: run through some of the powers and abilities attributed to them, again, 303 00:17:50,160 --> 00:17:55,280 Speaker 2: we're dealing very much with the legendary supernatural end of 304 00:17:55,320 --> 00:17:59,400 Speaker 2: the of the the ninja pop cultural world here and 305 00:17:59,440 --> 00:18:03,680 Speaker 2: not his reality. Though perhaps you know, if you read 306 00:18:03,720 --> 00:18:06,720 Speaker 2: between the lines, you can sort of see like realistic spycraft, 307 00:18:08,320 --> 00:18:10,120 Speaker 2: you know, at the heart of some of these legends. 308 00:18:10,400 --> 00:18:13,040 Speaker 2: So according to Joda and All, there were several abilities 309 00:18:13,160 --> 00:18:15,880 Speaker 2: that were said to be linked to conception, such as 310 00:18:16,119 --> 00:18:18,719 Speaker 2: the power to remove an unborn child from the womb, 311 00:18:19,119 --> 00:18:22,720 Speaker 2: change its features, and then return it to the womb. 312 00:18:23,560 --> 00:18:26,399 Speaker 2: Also the transfer of an unborn child from one woman 313 00:18:26,440 --> 00:18:30,800 Speaker 2: to another, and the ability for female shinobi to choose 314 00:18:30,800 --> 00:18:33,679 Speaker 2: to have a baby with any partner they've slept with 315 00:18:33,760 --> 00:18:36,840 Speaker 2: over the last ten months. This last one I found 316 00:18:36,880 --> 00:18:41,840 Speaker 2: pretty interesting because some organisms actually do engage in female 317 00:18:41,880 --> 00:18:45,160 Speaker 2: sperm storage, a form of sexual selection by which sperm 318 00:18:45,200 --> 00:18:47,959 Speaker 2: cells are retained by the receiving female for a period, 319 00:18:48,200 --> 00:18:51,800 Speaker 2: sometimes a prolong period of time before using said sperm. 320 00:18:52,359 --> 00:18:55,080 Speaker 2: Human beings do not do this, but you do find 321 00:18:55,160 --> 00:18:57,560 Speaker 2: some organisms that do. 322 00:18:57,760 --> 00:18:59,200 Speaker 3: I recall reading about sharks. 323 00:18:59,480 --> 00:19:05,320 Speaker 2: Yes, yes, sharks are a great example, and yeah, sometimes 324 00:19:05,320 --> 00:19:10,000 Speaker 2: this involves post copulatory cryptic female choice. I believes the 325 00:19:10,080 --> 00:19:15,640 Speaker 2: terminology via various methods. So it is interesting that, yeah, 326 00:19:15,680 --> 00:19:20,119 Speaker 2: this is a supposed ability of legendary mythic female ninja, 327 00:19:20,200 --> 00:19:23,439 Speaker 2: but you have to go into the animal world to 328 00:19:23,520 --> 00:19:26,640 Speaker 2: find examples of it in reality. Now, it should also 329 00:19:26,680 --> 00:19:28,720 Speaker 2: come as no surprise, given the sort of fem fatale 330 00:19:28,800 --> 00:19:31,879 Speaker 2: nature of female ninja and pop culture, that some of 331 00:19:31,880 --> 00:19:36,040 Speaker 2: their weapons are related to seduction and sex. If go 332 00:19:36,040 --> 00:19:39,040 Speaker 2: ahead and maybe skip fifteen seconds of this if you 333 00:19:39,080 --> 00:19:42,879 Speaker 2: just want to skip the very mild details here, but 334 00:19:43,240 --> 00:19:46,720 Speaker 2: here they are. They include death by orgasm, death by 335 00:19:46,760 --> 00:19:51,160 Speaker 2: reversing the male's reproductive ejection, shall we say, back into 336 00:19:51,240 --> 00:19:54,520 Speaker 2: his body, killing him in the process. And then there's 337 00:19:54,520 --> 00:19:58,240 Speaker 2: the technique where they seduce a man so hard that 338 00:19:58,320 --> 00:20:01,720 Speaker 2: he's mentally turned into an infant. Hmmm, great trick if 339 00:20:01,720 --> 00:20:02,360 Speaker 2: you can put it off. 340 00:20:02,600 --> 00:20:03,760 Speaker 3: Yeah. 341 00:20:03,960 --> 00:20:06,480 Speaker 2: Now, I'm not sure that Frank Herbert was directly inspired 342 00:20:06,480 --> 00:20:08,280 Speaker 2: by any of this, and if I had to guess, 343 00:20:08,280 --> 00:20:10,480 Speaker 2: I would say he was probably not. But I have 344 00:20:10,640 --> 00:20:13,600 Speaker 2: read that he did study Japanese and Chinese culture, among 345 00:20:13,920 --> 00:20:16,439 Speaker 2: you know, so many other things, so it's not impossible 346 00:20:16,480 --> 00:20:18,920 Speaker 2: that he got some inspiration from all of this, and 347 00:20:19,080 --> 00:20:24,680 Speaker 2: certainly like some of these the detailed classifications of spycraft. 348 00:20:25,280 --> 00:20:28,679 Speaker 2: We do see these reflected in the Dune series. You know, 349 00:20:28,680 --> 00:20:33,720 Speaker 2: it's just thinking earlier about the Hearkenans hiding somebody away 350 00:20:34,080 --> 00:20:38,880 Speaker 2: in the walls in Araken as as an assassination attempt 351 00:20:38,880 --> 00:20:40,960 Speaker 2: on the royal household. You know, there's somebody who was 352 00:20:41,000 --> 00:20:43,600 Speaker 2: like locked up for days or whatnot. You know, so 353 00:20:44,720 --> 00:20:47,320 Speaker 2: who knows, maybe he was inspired by it, maybe not. 354 00:20:47,840 --> 00:20:51,600 Speaker 2: Now for other magical arts attributed to the ninja, well 355 00:20:51,600 --> 00:20:55,480 Speaker 2: we've already mentioned the fictional phantom toad summoning of Juriah, 356 00:20:56,200 --> 00:20:58,800 Speaker 2: but there are some other interesting ones as well, and 357 00:20:59,000 --> 00:21:01,119 Speaker 2: Yoda and all mentions these, and again not all of 358 00:21:01,160 --> 00:21:04,800 Speaker 2: these are definitely classified as ninja or shnoby, but a 359 00:21:04,840 --> 00:21:07,760 Speaker 2: lot of them are kind of shinnobi adjacent. And then 360 00:21:07,840 --> 00:21:10,160 Speaker 2: again you have to think about the fact that as 361 00:21:10,880 --> 00:21:15,920 Speaker 2: ninja myths in the popular culture kind of coalesce, they're 362 00:21:15,920 --> 00:21:19,920 Speaker 2: going to draw in multiple things. So one figure worth 363 00:21:19,920 --> 00:21:25,040 Speaker 2: looking at is sixteenth century sage Kashin Kogi. Not a ninja, 364 00:21:25,200 --> 00:21:28,719 Speaker 2: more of a wizard attributed with various acts of illusion 365 00:21:28,920 --> 00:21:33,080 Speaker 2: and shape shifting, so he would do things like allegedly 366 00:21:33,119 --> 00:21:36,640 Speaker 2: throw leaves into the water and make them turn into fish. 367 00:21:36,680 --> 00:21:39,640 Speaker 2: Various other entertaining illusions that are maybe not that far 368 00:21:39,760 --> 00:21:44,240 Speaker 2: removed from the idea of somebody doing little illusionary tricks 369 00:21:44,640 --> 00:21:46,520 Speaker 2: on the sidewalk or in a subway station. 370 00:21:46,920 --> 00:21:47,960 Speaker 3: Oh that's interesting. 371 00:21:48,160 --> 00:21:51,639 Speaker 2: Yeah, but yeah, he was according to legend, he was 372 00:21:51,680 --> 00:21:55,600 Speaker 2: something of a trickster for sure. For instance, there's this 373 00:21:55,680 --> 00:21:58,840 Speaker 2: story that he painted a detailed illustration of the torments 374 00:21:58,880 --> 00:22:01,600 Speaker 2: of Hell that when you looked at it, it seemed 375 00:22:01,640 --> 00:22:05,080 Speaker 2: animated to the naked eye, So you know, do with 376 00:22:05,160 --> 00:22:07,560 Speaker 2: that way you will. Maybe it was just like really detailed. 377 00:22:07,760 --> 00:22:11,239 Speaker 2: Maybe there was some sort of effect involved, or it 378 00:22:11,280 --> 00:22:14,560 Speaker 2: was magic. You know, he's a magical painter, and it 379 00:22:14,600 --> 00:22:16,960 Speaker 2: looks like it moves like, you know, Harry Potter style 380 00:22:17,080 --> 00:22:19,639 Speaker 2: or something, and everybody was really impressed by it, and 381 00:22:19,680 --> 00:22:22,240 Speaker 2: in fact, the powerful daimyo some called him the demon 382 00:22:22,320 --> 00:22:27,440 Speaker 2: Daimyo Nabunaga, insisted on buying it, and the negotiations apparently 383 00:22:27,440 --> 00:22:31,560 Speaker 2: included at least one assassination attempt on the artist, and 384 00:22:32,040 --> 00:22:36,000 Speaker 2: you know, but Cogie stuck to his guns and finally 385 00:22:36,040 --> 00:22:38,399 Speaker 2: agreed to sell it for just a crazy sum, just 386 00:22:39,400 --> 00:22:41,880 Speaker 2: I don't know how much, but a lot, at which 387 00:22:41,920 --> 00:22:46,720 Speaker 2: point the art suddenly lost its animated magic, and Nabonica 388 00:22:46,760 --> 00:22:49,960 Speaker 2: is like, what happened? Why is it not moving anymore? 389 00:22:49,960 --> 00:22:53,240 Speaker 2: Why is it not you knows as amazing as was previously, 390 00:22:53,560 --> 00:22:56,320 Speaker 2: And He's like, well, it used to be priceless, but 391 00:22:56,640 --> 00:22:58,640 Speaker 2: then we agreed on a price, and so the quality 392 00:22:58,680 --> 00:23:02,000 Speaker 2: of the piece adjusted to that sounds like a great 393 00:23:02,000 --> 00:23:03,679 Speaker 2: way to get beheaded. But I don't know. You know, 394 00:23:03,720 --> 00:23:06,320 Speaker 2: that's the thing about being a trickster, daring, trickster wizard. 395 00:23:06,400 --> 00:23:07,880 Speaker 2: You can pull these things off. 396 00:23:07,880 --> 00:23:11,720 Speaker 3: I guess artists in the audience remember this negotiating. 397 00:23:11,160 --> 00:23:14,200 Speaker 2: Technique again, Yeah, yeah, try and pull that one off. 398 00:23:14,480 --> 00:23:16,960 Speaker 2: So Koji again not a ninja, but a figure that 399 00:23:17,000 --> 00:23:21,119 Speaker 2: crosses over with some of the attributed magics of the ninja, 400 00:23:21,600 --> 00:23:24,199 Speaker 2: and as a pop culture figure, he does pop up 401 00:23:24,200 --> 00:23:27,000 Speaker 2: in a lot of ninja media, such as nineteen eighty 402 00:23:27,000 --> 00:23:31,480 Speaker 2: two's Ninja Wars aka Death of a Ninja starring hero 403 00:23:31,560 --> 00:23:34,720 Speaker 2: Yuki Sonata, a major actor who would go on to 404 00:23:34,840 --> 00:23:37,120 Speaker 2: of course have a starring role in the recent Showgun 405 00:23:37,160 --> 00:23:40,280 Speaker 2: series on FX, but also he played Scorpion in the 406 00:23:40,359 --> 00:23:43,720 Speaker 2: Ninja in one of those in that recent Mortal Kombat film, 407 00:23:43,800 --> 00:23:47,400 Speaker 2: so definitely a figure that has immersed in the Ninja lore, 408 00:23:47,440 --> 00:23:48,920 Speaker 2: and I think he's popped up in a film or 409 00:23:48,920 --> 00:23:52,600 Speaker 2: two for Weird House Cinema, great actor. I have not 410 00:23:52,680 --> 00:23:54,920 Speaker 2: seen Ninja Wars, though, so I can't really vouch for it. 411 00:23:55,440 --> 00:23:59,399 Speaker 2: All right, Shall we get into some more alleged ninja 412 00:23:59,400 --> 00:24:00,760 Speaker 2: technology of note? 413 00:24:01,040 --> 00:24:02,479 Speaker 3: Yes, absolutely so. 414 00:24:02,520 --> 00:24:05,680 Speaker 2: As we previously discussed, the modern trope of the ninja 415 00:24:05,880 --> 00:24:08,840 Speaker 2: typically involves their use of a traditional martial art that 416 00:24:08,920 --> 00:24:12,919 Speaker 2: prioritizes medieval weaponry. Right, so these ninjas will use a 417 00:24:13,000 --> 00:24:16,399 Speaker 2: schuriken to bypass a security panel. They will kill a 418 00:24:16,480 --> 00:24:19,080 Speaker 2: robot with a sword, right, you know exactly what I'm 419 00:24:19,080 --> 00:24:19,920 Speaker 2: getting at here? Oh? 420 00:24:19,960 --> 00:24:20,840 Speaker 3: Yes, Yeah. 421 00:24:20,960 --> 00:24:24,160 Speaker 2: In reality, though, as we've been stressing, the Shanobi would 422 00:24:24,200 --> 00:24:27,080 Speaker 2: have used whatever tools were necessary and available to them, 423 00:24:27,119 --> 00:24:31,080 Speaker 2: including what was essentially cutting edge technology, like the latest 424 00:24:31,119 --> 00:24:34,880 Speaker 2: in explosives, the latest in chemistry, the latest in firearms. 425 00:24:35,320 --> 00:24:37,840 Speaker 2: And so we do have some examples of this sort 426 00:24:37,840 --> 00:24:41,679 Speaker 2: of thing. Again, with the huge caveat that, we have 427 00:24:41,720 --> 00:24:45,639 Speaker 2: a lot of crossing of history and legend here. But 428 00:24:46,160 --> 00:24:52,280 Speaker 2: fifteenth century Shnobi commander mochiuki Izumo Nokami is said to 429 00:24:52,359 --> 00:24:57,960 Speaker 2: have utilized smoke bombs, pyrotechnics, code signals, and some form 430 00:24:58,000 --> 00:25:01,399 Speaker 2: of weather prediction. And I'm not sure to what extent 431 00:25:01,440 --> 00:25:06,000 Speaker 2: we're talking about weather prediction that based on like acceptable 432 00:25:06,080 --> 00:25:08,240 Speaker 2: models and methods or something that was maybe a little 433 00:25:08,240 --> 00:25:12,760 Speaker 2: more supernatural in form, but you know, both are likely 434 00:25:12,840 --> 00:25:13,760 Speaker 2: to some degree. 435 00:25:14,000 --> 00:25:16,679 Speaker 3: Yeah, remember some of these Ninjasu manuals did involve like 436 00:25:16,760 --> 00:25:18,200 Speaker 3: divination and astrology. 437 00:25:18,560 --> 00:25:21,199 Speaker 2: Yeah, and so ninja throughout the centuries were said to 438 00:25:21,400 --> 00:25:25,840 Speaker 2: use nouroshi no jutsu smoke bombs, though Yoda and All 439 00:25:25,880 --> 00:25:29,440 Speaker 2: stress that these were likely quote carefully placed in ignited 440 00:25:29,520 --> 00:25:33,560 Speaker 2: smoke pots, given the limited pyrotechnic abilities of the time, 441 00:25:34,359 --> 00:25:36,400 Speaker 2: and that also they would use things that we would 442 00:25:36,400 --> 00:25:39,400 Speaker 2: think of as just simple firecrackers to serve as distractions, 443 00:25:39,440 --> 00:25:42,280 Speaker 2: you know, set off a little pop over here, just 444 00:25:42,400 --> 00:25:44,560 Speaker 2: enough distraction to do whatever it is you need to do, 445 00:25:44,920 --> 00:25:48,879 Speaker 2: be that something more pop culture ninja ish, as sneak 446 00:25:48,960 --> 00:25:51,800 Speaker 2: from one point to another or you know, switch out 447 00:25:51,800 --> 00:25:54,000 Speaker 2: a piece of paper in an office, that sort of thing. 448 00:25:55,440 --> 00:25:58,120 Speaker 2: But yeah, the smoke bombs, of course, are a huge 449 00:25:58,119 --> 00:25:59,720 Speaker 2: part of the ninja myth, and they spill over into 450 00:25:59,720 --> 00:26:02,320 Speaker 2: Batman as well. Like Batman's always throwing smoke bombs and 451 00:26:02,320 --> 00:26:07,080 Speaker 2: disappearing right, and the reality is maybe less as instantly 452 00:26:07,480 --> 00:26:11,239 Speaker 2: dramatic as that. It might have been more something that 453 00:26:11,400 --> 00:26:14,080 Speaker 2: involved like placing something, lighting it and waiting for the 454 00:26:14,080 --> 00:26:18,000 Speaker 2: smoke to build up. Right. Now, getting into the use 455 00:26:18,200 --> 00:26:22,360 Speaker 2: of weaponry, we have the example of sixteenth century assassin 456 00:26:22,880 --> 00:26:27,280 Speaker 2: of Sujatini Zunjuvo, and he is noted for his use 457 00:26:27,320 --> 00:26:31,119 Speaker 2: of the Japanese matchlock rifle. So this is an individual 458 00:26:31,200 --> 00:26:37,639 Speaker 2: that was definitely an assassin, definitely an attempted assassin, definitely 459 00:26:37,880 --> 00:26:41,640 Speaker 2: a marksman. Was he a Shinobi, I don't know. I'm 460 00:26:41,640 --> 00:26:43,280 Speaker 2: not as sure on that. I think you could say 461 00:26:43,280 --> 00:26:46,280 Speaker 2: that he definitely engaged in a major Shnobi activity, though 462 00:26:47,000 --> 00:26:49,960 Speaker 2: this was apparently a Kdo clan marksman task with the 463 00:26:50,000 --> 00:26:55,800 Speaker 2: assassination of Oda Nobunaga himself, a local warlord was said 464 00:26:55,800 --> 00:26:57,720 Speaker 2: to have hired him for the task and provided with 465 00:26:57,840 --> 00:27:01,720 Speaker 2: key intel about Nabonaga's scheduled brands that through a particular 466 00:27:01,800 --> 00:27:04,760 Speaker 2: pass in Omi. This would have been on May nineteenth, 467 00:27:05,000 --> 00:27:08,960 Speaker 2: fifteen seventy, so you know, basic you know, sort of 468 00:27:09,000 --> 00:27:13,120 Speaker 2: sniper operations here. He set up a position days in advance, 469 00:27:13,560 --> 00:27:16,080 Speaker 2: using like the patience of the shnobe, if nothing else 470 00:27:16,640 --> 00:27:20,840 Speaker 2: until okay, here it comes the retinue. Here comes Tobunuga 471 00:27:21,000 --> 00:27:24,520 Speaker 2: in armor on his on his steed, accompanied by all 472 00:27:24,560 --> 00:27:28,840 Speaker 2: of his men, and our would be assassin. Here Zenjubo 473 00:27:29,400 --> 00:27:32,200 Speaker 2: knows that he really only has one shot. You know, 474 00:27:32,480 --> 00:27:36,440 Speaker 2: this is this is a matchlock rifle. You know, he's 475 00:27:36,520 --> 00:27:40,040 Speaker 2: not rapid fire. He's going to get one shot off 476 00:27:40,320 --> 00:27:42,200 Speaker 2: and then it's going to be so loud and it's 477 00:27:42,200 --> 00:27:45,199 Speaker 2: going to produce a discharge of smoke and he's not like, 478 00:27:45,280 --> 00:27:47,960 Speaker 2: you know, miles away or anything. So he knows that 479 00:27:48,040 --> 00:27:51,360 Speaker 2: the instant he fires this shot, they're going to mark 480 00:27:51,400 --> 00:27:54,639 Speaker 2: his position, and so he needs to he needs to 481 00:27:54,680 --> 00:27:56,760 Speaker 2: make sure that that shot lands home or he's going 482 00:27:56,840 --> 00:27:58,480 Speaker 2: to have to like try and get off a second 483 00:27:58,520 --> 00:28:01,920 Speaker 2: one if he can. So he fires the shot, knocks 484 00:28:01,920 --> 00:28:05,640 Speaker 2: Innabunika from his horse, but as it turns out, does 485 00:28:05,680 --> 00:28:08,240 Speaker 2: not kill him because the collar armor that he's wearing 486 00:28:08,320 --> 00:28:13,199 Speaker 2: absorbs the shot. So Zenjubo flees. He hides that he 487 00:28:13,280 --> 00:28:17,760 Speaker 2: is eventually caught and subjected to slow execution. I believe 488 00:28:17,880 --> 00:28:19,840 Speaker 2: the story is that they buried him up to his 489 00:28:19,920 --> 00:28:22,120 Speaker 2: neck in the sand and like sawed his head off. 490 00:28:22,480 --> 00:28:22,760 Speaker 3: Wow. 491 00:28:23,160 --> 00:28:26,240 Speaker 2: Now it was worth noting that snipers then and now 492 00:28:27,200 --> 00:28:31,280 Speaker 2: sometimes utilized breathing techniques to steady one's aim in. Various 493 00:28:31,320 --> 00:28:33,600 Speaker 2: breathing techniques and things that you could also think of 494 00:28:33,640 --> 00:28:36,919 Speaker 2: as like self hypnosis have also been attributed to the 495 00:28:36,960 --> 00:28:41,640 Speaker 2: shnobi in general to aid in stealth or patience. Now, 496 00:28:41,680 --> 00:28:43,720 Speaker 2: at this point, let's come back to the idea of 497 00:28:43,760 --> 00:28:46,959 Speaker 2: a ninja sword, something that is just inseparable from the 498 00:28:47,000 --> 00:28:51,400 Speaker 2: modern myth of the ninja. In fact, we already in 499 00:28:51,480 --> 00:28:54,400 Speaker 2: passing I think, talked about teenage mutant ninja turtles with katana. 500 00:28:54,960 --> 00:28:58,200 Speaker 2: You know, like, if you're gonna make turtles into ninjas, 501 00:28:58,240 --> 00:29:00,720 Speaker 2: you give one of them swords. Just what you do. 502 00:29:01,040 --> 00:29:03,120 Speaker 2: And we actually heard from at least one listener who 503 00:29:03,120 --> 00:29:04,920 Speaker 2: wrote in and was like, oh yeah, there's actually the 504 00:29:04,960 --> 00:29:09,239 Speaker 2: whole thing about the ninja having a specific sword, the 505 00:29:09,280 --> 00:29:15,479 Speaker 2: shoby katana. But as this listener pointed out, and as 506 00:29:15,800 --> 00:29:18,400 Speaker 2: is discussed in the text we were working from, this 507 00:29:18,520 --> 00:29:22,400 Speaker 2: sword's exact form is at least a matter of some controversy. 508 00:29:22,800 --> 00:29:25,800 Speaker 2: There are a lot of strong arguments that this sword 509 00:29:25,880 --> 00:29:29,280 Speaker 2: never existed at all. This is one of those examples 510 00:29:29,320 --> 00:29:32,680 Speaker 2: where we don't see mention of it in the historic 511 00:29:32,800 --> 00:29:38,360 Speaker 2: ninja guide books and instruction manuals. There's a very strong 512 00:29:38,440 --> 00:29:43,040 Speaker 2: argument that these were created entirely in the twentieth century, 513 00:29:43,320 --> 00:29:45,520 Speaker 2: though again, this is certainly something where then you can 514 00:29:45,560 --> 00:29:47,920 Speaker 2: go around and buy one at a mall in like Wisconsin. 515 00:29:48,040 --> 00:29:51,360 Speaker 2: So you can argue that while the shinobi katana exists, 516 00:29:51,360 --> 00:29:53,800 Speaker 2: now you see it in movies and you can buy 517 00:29:53,840 --> 00:29:59,080 Speaker 2: one at the mall. But let's get into the idea 518 00:29:59,120 --> 00:30:01,160 Speaker 2: of it, at least the myth of it. The idea 519 00:30:01,200 --> 00:30:03,840 Speaker 2: is that this would be a short straight blade with 520 00:30:03,920 --> 00:30:06,640 Speaker 2: a pointed scabbard, So the scabbard has a point at 521 00:30:06,640 --> 00:30:10,240 Speaker 2: the end and also a simple square guard you know, 522 00:30:10,280 --> 00:30:13,280 Speaker 2: at the between the hilt and the blade, and the 523 00:30:13,320 --> 00:30:15,680 Speaker 2: aspects of its design were said to be very practical 524 00:30:15,880 --> 00:30:18,600 Speaker 2: for the ninja. So the pointed scabbard allowed it to 525 00:30:18,640 --> 00:30:21,000 Speaker 2: be driven into the ground so it could be he 526 00:30:21,000 --> 00:30:24,480 Speaker 2: could serve as a footstool to aid in climbing. I 527 00:30:24,480 --> 00:30:27,640 Speaker 2: think there's some other stories about the scabbard being used 528 00:30:27,680 --> 00:30:29,760 Speaker 2: as like a breathing tube if an engine needed to 529 00:30:29,920 --> 00:30:33,080 Speaker 2: go into water. I'm not sure why that is would 530 00:30:33,120 --> 00:30:35,800 Speaker 2: be more effective than having a breathing tube on you 531 00:30:35,960 --> 00:30:37,160 Speaker 2: or using a reed or something. 532 00:30:37,600 --> 00:30:40,560 Speaker 3: Yeah, trying to imagine now. I think the idea with 533 00:30:40,640 --> 00:30:43,520 Speaker 3: the scabbard is that you wouldn't you could stab it 534 00:30:43,600 --> 00:30:47,000 Speaker 3: into the ground within its scabbard and then stand on 535 00:30:47,040 --> 00:30:49,080 Speaker 3: the hilt of the sword to like hop over a 536 00:30:49,120 --> 00:30:51,080 Speaker 3: wall and then like pull it up by a rope. 537 00:30:52,640 --> 00:30:54,240 Speaker 3: That's the idea, because I guess if you were to 538 00:30:54,240 --> 00:30:56,760 Speaker 3: stab the blade of the sword into the ground that 539 00:30:56,880 --> 00:31:00,240 Speaker 3: the ideas that would dull it. But I'd also seen 540 00:31:00,320 --> 00:31:04,120 Speaker 3: something about just generally using the scabbard of this sword 541 00:31:04,160 --> 00:31:07,480 Speaker 3: as a kind of like a feeler, like an untinnee 542 00:31:07,560 --> 00:31:08,200 Speaker 3: in the dark. 543 00:31:08,720 --> 00:31:11,360 Speaker 2: Yeah, the idea that you would kind of like partially 544 00:31:11,440 --> 00:31:14,400 Speaker 2: unsheathe your sword, hold it out in front of you, 545 00:31:14,960 --> 00:31:17,400 Speaker 2: and if you like tapped into something, you're like, oh, 546 00:31:17,440 --> 00:31:19,000 Speaker 2: there's a person there, and then you can pull your 547 00:31:19,040 --> 00:31:22,000 Speaker 2: sword out and like slash them or something. I think 548 00:31:22,000 --> 00:31:24,000 Speaker 2: it's been referred to as like a person detector or 549 00:31:24,040 --> 00:31:26,880 Speaker 2: a people detector. And of course there's the other obvious 550 00:31:26,920 --> 00:31:30,360 Speaker 2: idea that if you're doing some sneaking around and potentially 551 00:31:30,520 --> 00:31:34,000 Speaker 2: using that weapon in a confined space, it pays for 552 00:31:34,080 --> 00:31:36,280 Speaker 2: your sword to be short as opposed to being some 553 00:31:36,320 --> 00:31:39,200 Speaker 2: sort of like a longer sword, So this would be 554 00:31:39,320 --> 00:31:43,000 Speaker 2: in keeping with operations that require disguise and so forth 555 00:31:43,200 --> 00:31:46,760 Speaker 2: easier to hide, easier to carry, and all that. So again, 556 00:31:46,960 --> 00:31:49,080 Speaker 2: very strong argument to be made that these were just 557 00:31:49,080 --> 00:31:52,880 Speaker 2: invented in the twentieth century as part of outright ninja 558 00:31:52,920 --> 00:31:56,640 Speaker 2: fiction and myth making. But something that Yoda and All 559 00:31:56,640 --> 00:31:59,320 Speaker 2: point out is that, Okay, if these swords did exist, 560 00:32:00,280 --> 00:32:02,440 Speaker 2: which depending on where you land on this could be 561 00:32:02,440 --> 00:32:05,960 Speaker 2: a huge if they would have been very simple, they 562 00:32:06,000 --> 00:32:08,520 Speaker 2: wouldn't have been ornate because they would not have been 563 00:32:08,600 --> 00:32:13,120 Speaker 2: forged by a master swordsmith, one of these individuals responsible 564 00:32:13,160 --> 00:32:18,560 Speaker 2: for the just the elegant superiority of the noble samurai sword. 565 00:32:18,920 --> 00:32:21,240 Speaker 2: But or rather, these would have been made by blacksmiths 566 00:32:21,560 --> 00:32:24,400 Speaker 2: in the country, probably who were willing to take a 567 00:32:24,480 --> 00:32:28,640 Speaker 2: risk making an illegal sword. M because remember, your average 568 00:32:28,640 --> 00:32:32,120 Speaker 2: shenobi here is not, if not an actual criminal, is 569 00:32:32,160 --> 00:32:35,240 Speaker 2: at least a common born person, and it was illegal 570 00:32:35,520 --> 00:32:38,840 Speaker 2: for commoners to own a weapon of any kind. So 571 00:32:38,960 --> 00:32:42,600 Speaker 2: these would have been dirty weapons made for dirty practitioners 572 00:32:43,160 --> 00:32:46,560 Speaker 2: of the sketchy arts. Yeah, and I think we also 573 00:32:46,680 --> 00:32:49,240 Speaker 2: might want to consider it questions of necessity, Right, would 574 00:32:49,240 --> 00:32:52,640 Speaker 2: is Shenoby operative need a sword, because even a small 575 00:32:52,680 --> 00:32:57,400 Speaker 2: sword is fairly sizable, and especially if you consider, well, 576 00:32:57,840 --> 00:32:59,160 Speaker 2: what are you going to use it for? Are you 577 00:32:59,160 --> 00:33:01,840 Speaker 2: gonna are you gonna engage in a sword fight? Probably not. 578 00:33:03,280 --> 00:33:05,240 Speaker 2: And if you do need some sort of a sharp 579 00:33:05,240 --> 00:33:08,520 Speaker 2: object as a weapon or a tool, well, there are 580 00:33:08,520 --> 00:33:12,000 Speaker 2: other choices you could make, such as a common field knife, 581 00:33:12,680 --> 00:33:17,000 Speaker 2: some other kind of like sharpened tool that on one hand, 582 00:33:17,160 --> 00:33:20,200 Speaker 2: maybe doesn't constitute a full weapon, and so for you're 583 00:33:20,200 --> 00:33:22,680 Speaker 2: not like you're not going to be found out immediately 584 00:33:22,720 --> 00:33:24,440 Speaker 2: just because you have it on your person, but the 585 00:33:24,520 --> 00:33:27,520 Speaker 2: kind of thing that could be used as a weapon 586 00:33:28,360 --> 00:33:31,680 Speaker 2: if things got dire, and in the cases where they 587 00:33:31,680 --> 00:33:34,480 Speaker 2: did use swords, yeah, we're probably talking about the equivalent 588 00:33:34,480 --> 00:33:46,080 Speaker 2: of some sort of like a black market sword. Now, 589 00:33:46,160 --> 00:33:50,080 Speaker 2: these again are all like pretty standard pop culture ninja weapons, 590 00:33:50,080 --> 00:33:53,840 Speaker 2: though I think it's even more fun to get into 591 00:33:53,840 --> 00:33:58,040 Speaker 2: some of the perhaps weirder technologies that ninja are held 592 00:33:58,080 --> 00:33:59,040 Speaker 2: to have utilized. 593 00:33:59,520 --> 00:34:03,680 Speaker 3: Right, I think it's time to talk about misugumo. Misugumo 594 00:34:04,160 --> 00:34:08,640 Speaker 3: is a device described in the sixth volume of the 595 00:34:08,760 --> 00:34:13,400 Speaker 3: seventeenth century ninjitsu manual Mansen Chu Kai, which I mentioned earlier, 596 00:34:13,800 --> 00:34:17,200 Speaker 3: and the sixth volume is sort of a It describes 597 00:34:17,280 --> 00:34:20,480 Speaker 3: various pieces of ninjitsu equipment and gadget It's kind of 598 00:34:20,520 --> 00:34:25,200 Speaker 3: a ce branch compendium. Now, when it comes to the misugumo, 599 00:34:25,880 --> 00:34:29,040 Speaker 3: there is a way in which it has commonly been 600 00:34:29,200 --> 00:34:33,359 Speaker 3: interpreted in twentieth century sources, and then there is a 601 00:34:33,560 --> 00:34:37,200 Speaker 3: revisionist understanding of it, which I think seems much more 602 00:34:37,320 --> 00:34:40,400 Speaker 3: likely what the original source is intended. I'm going to 603 00:34:40,480 --> 00:34:44,839 Speaker 3: start off by talking about the more likely confused interpretation. 604 00:34:45,400 --> 00:34:50,479 Speaker 3: So misugumo literally means water spider, and it's clear from 605 00:34:50,600 --> 00:34:53,960 Speaker 3: the context in which this device is described that it's 606 00:34:54,160 --> 00:34:59,080 Speaker 3: some kind of floatation device. So in some popular ninja 607 00:34:59,080 --> 00:35:02,520 Speaker 3: literature of the twentyth century, it has been interpreted as 608 00:35:02,560 --> 00:35:07,200 Speaker 3: a kind of footwear that allows the ninja to walk 609 00:35:07,320 --> 00:35:10,239 Speaker 3: on top of the water, often said to be used 610 00:35:10,280 --> 00:35:14,960 Speaker 3: for crossing the watery moat surrounding a castle. So imagine 611 00:35:15,040 --> 00:35:19,239 Speaker 3: a kind of wooden sandal that is a little rectangular 612 00:35:19,320 --> 00:35:22,680 Speaker 3: sandal in the middle bound with twine in the center 613 00:35:22,800 --> 00:35:26,960 Speaker 3: of a large flat disk made out of wooden quarter 614 00:35:27,120 --> 00:35:31,719 Speaker 3: circle pieces. So you imagine a round disc with a 615 00:35:31,760 --> 00:35:35,680 Speaker 3: hollow center made out of wood cut into four different pieces, 616 00:35:36,040 --> 00:35:38,360 Speaker 3: and they're bound together with twine. And then in the 617 00:35:38,400 --> 00:35:41,640 Speaker 3: middle you've got this little flat sandal soul to stand on. 618 00:35:42,239 --> 00:35:44,560 Speaker 3: You can look up illustrations of this if you want. 619 00:35:44,600 --> 00:35:47,600 Speaker 3: But this idea, in the first interpretation, is that the 620 00:35:47,680 --> 00:35:50,839 Speaker 3: ninja would stand on these and then use them to 621 00:35:51,000 --> 00:35:54,080 Speaker 3: walk across the surface of the water, because hey, wood 622 00:35:54,120 --> 00:35:59,040 Speaker 3: floats right now, Would this actually work? Would such a 623 00:35:59,080 --> 00:36:02,600 Speaker 3: device allow you to walk on water? I think we 624 00:36:02,640 --> 00:36:06,040 Speaker 3: can start by thinking about its namesake, which is the 625 00:36:06,040 --> 00:36:11,160 Speaker 3: water spider. There are insects and spiders that are able 626 00:36:11,239 --> 00:36:14,399 Speaker 3: to walk across the surface of the water without sinking in. 627 00:36:14,480 --> 00:36:16,520 Speaker 3: There are a number of different species that can do this, 628 00:36:16,960 --> 00:36:19,760 Speaker 3: So how do they do it well? There are generally 629 00:36:19,840 --> 00:36:23,520 Speaker 3: two physical forces that they can take advantage of. One 630 00:36:23,640 --> 00:36:28,440 Speaker 3: is standard buoyancy. This works by displacing water with a 631 00:36:28,560 --> 00:36:33,000 Speaker 3: lower density object, and this is how boats float. Boats 632 00:36:33,040 --> 00:36:36,360 Speaker 3: float by having a hollow hull, thus displacing more weight 633 00:36:36,400 --> 00:36:38,759 Speaker 3: in water than their own weight, so they get to 634 00:36:38,760 --> 00:36:41,319 Speaker 3: sit on top of the water without sinking down. The 635 00:36:41,400 --> 00:36:46,000 Speaker 3: other physical factor is surface tension. Insects and spiders are 636 00:36:46,040 --> 00:36:50,200 Speaker 3: small enough that different forces play a major role in 637 00:36:50,280 --> 00:36:52,920 Speaker 3: the way they move through the world, and the surface 638 00:36:53,000 --> 00:36:56,839 Speaker 3: tension of water is one of those forces. Water is 639 00:36:56,920 --> 00:37:01,000 Speaker 3: a polar molecule, so it likes to stick to itself, 640 00:37:01,360 --> 00:37:04,000 Speaker 3: and when there's a mass of water, it forms a 641 00:37:04,080 --> 00:37:08,239 Speaker 3: kind of skin on its surface, with the water molecules 642 00:37:08,280 --> 00:37:11,520 Speaker 3: clinging very tightly to each other and to some extent 643 00:37:11,719 --> 00:37:16,400 Speaker 3: resisting being split apart. So it takes some force actually 644 00:37:16,480 --> 00:37:20,239 Speaker 3: to break through this surface layer of water. Now, given 645 00:37:20,280 --> 00:37:23,560 Speaker 3: the mass of a human body, Earth's gravity pulling us 646 00:37:23,600 --> 00:37:27,239 Speaker 3: downward into a pool of water quite easily overcomes the 647 00:37:27,280 --> 00:37:30,120 Speaker 3: surface tension of water, and we plunge right in. But 648 00:37:30,640 --> 00:37:34,560 Speaker 3: as you become smaller and smaller and your mass becomes smaller, 649 00:37:35,080 --> 00:37:39,080 Speaker 3: gravity becomes less relevant and the surface tension of water 650 00:37:39,160 --> 00:37:44,360 Speaker 3: becomes more relevant. So some insects and spiders are specially 651 00:37:44,400 --> 00:37:48,840 Speaker 3: evolved to take advantage of the power of surface tension 652 00:37:48,960 --> 00:37:53,240 Speaker 3: at their body size by having hydrophobic or water repelling 653 00:37:53,360 --> 00:37:57,680 Speaker 3: surfaces and hairs on their bodies and especially on their feet, 654 00:37:58,040 --> 00:38:01,239 Speaker 3: And these surfaces they from one thing. They spread out 655 00:38:01,280 --> 00:38:04,520 Speaker 3: their weight over a larger surface area by having like 656 00:38:04,960 --> 00:38:07,680 Speaker 3: specially shaped feed and these hairs that allow them to 657 00:38:07,719 --> 00:38:11,080 Speaker 3: kind of spread out their footprint, so they distribute their 658 00:38:11,080 --> 00:38:13,040 Speaker 3: weight over a larger surface of the water. But they 659 00:38:13,080 --> 00:38:16,000 Speaker 3: also at the molecular level, tend to be made of 660 00:38:16,320 --> 00:38:19,920 Speaker 3: hydrophobic substances that do not want to get wet. They 661 00:38:20,040 --> 00:38:23,440 Speaker 3: chemically resist getting wet, and so they do not want 662 00:38:23,520 --> 00:38:27,120 Speaker 3: to penetrate the surface level of the water. And so 663 00:38:27,400 --> 00:38:31,000 Speaker 3: with the combination of these hydrophobic surfaces and distributing their 664 00:38:31,000 --> 00:38:34,120 Speaker 3: weight over the larger space, the arthropod is able to 665 00:38:34,200 --> 00:38:36,399 Speaker 3: walk or skate over the surface of the water by 666 00:38:36,400 --> 00:38:40,440 Speaker 3: taking advantage of that surface tension. This is great for insects, 667 00:38:40,600 --> 00:38:44,239 Speaker 3: but again it works because they are extremely small and 668 00:38:44,360 --> 00:38:47,520 Speaker 3: have very small mass. Once you start getting bigger and 669 00:38:47,560 --> 00:38:50,760 Speaker 3: having more mass to your body, you're just too big 670 00:38:50,880 --> 00:38:53,319 Speaker 3: to take advantage of the surface tension of water in 671 00:38:53,360 --> 00:38:53,799 Speaker 3: this way. 672 00:38:54,480 --> 00:38:57,359 Speaker 2: So you're saying Ninja might have been just really small. 673 00:38:58,320 --> 00:39:00,719 Speaker 3: If ninja were the size of insects. So yeah, you 674 00:39:01,160 --> 00:39:04,160 Speaker 3: can quite well imagine coming up with technology for running 675 00:39:04,200 --> 00:39:06,680 Speaker 3: over the surface of water. And that brings us back 676 00:39:06,719 --> 00:39:09,960 Speaker 3: to the Misigumo device. So I was not able to 677 00:39:10,000 --> 00:39:15,200 Speaker 3: find any rigorous testing of this device of recreations of 678 00:39:15,200 --> 00:39:18,920 Speaker 3: this device published in a scientific or historical journal. But 679 00:39:18,920 --> 00:39:22,439 Speaker 3: I've come across a few informal tests staged in things 680 00:39:22,440 --> 00:39:26,719 Speaker 3: like documentaries and TV programs, And having reviewed this evidence 681 00:39:26,760 --> 00:39:29,440 Speaker 3: and read what I could about it, my assessment is 682 00:39:29,560 --> 00:39:33,399 Speaker 3: this device would probably not work as described, at least 683 00:39:33,400 --> 00:39:37,200 Speaker 3: in the way it's interpreted here as footwear, unless the 684 00:39:37,239 --> 00:39:41,799 Speaker 3: shoes were absurdly large, much larger than the specifications in 685 00:39:41,840 --> 00:39:45,960 Speaker 3: the Ninjasu manual indicate, in which case I questioned the 686 00:39:46,000 --> 00:39:49,000 Speaker 3: extent to which you could be said to walk on 687 00:39:49,200 --> 00:39:53,239 Speaker 3: water as opposed to just floating upright on two small boats. 688 00:39:53,719 --> 00:39:56,680 Speaker 3: And in that case, why is this method of crossing 689 00:39:56,760 --> 00:40:01,080 Speaker 3: the water preferable to just piloting a small rat after canoe. 690 00:40:01,120 --> 00:40:04,160 Speaker 2: Right, because a small rafter canoe works, wonders like, there's 691 00:40:04,200 --> 00:40:08,600 Speaker 2: a reason we still use canoes and kayaks and so forth. 692 00:40:08,840 --> 00:40:11,279 Speaker 2: They're great. Why would you wear a couple of like 693 00:40:11,360 --> 00:40:14,160 Speaker 2: huge floaty clown shoes instead, especially if you're trying to 694 00:40:14,160 --> 00:40:14,680 Speaker 2: be stealthy? 695 00:40:15,000 --> 00:40:17,640 Speaker 3: That's right now, you might argue, well, you know, a 696 00:40:17,760 --> 00:40:20,279 Speaker 3: rafter canoe is big, and you have to it would 697 00:40:20,320 --> 00:40:22,799 Speaker 3: be hard to like carry it to the But in 698 00:40:22,960 --> 00:40:25,399 Speaker 3: order for these shoes to work. They would also need 699 00:40:25,440 --> 00:40:26,760 Speaker 3: to be big and hard to carry. 700 00:40:27,480 --> 00:40:30,319 Speaker 2: Yeah. I mean, I'm reminded of every time as a 701 00:40:30,400 --> 00:40:32,960 Speaker 2: child or even as an adult, where I've attempted to 702 00:40:33,080 --> 00:40:36,160 Speaker 2: stand on something floating and say a swimming pool, and 703 00:40:36,440 --> 00:40:39,000 Speaker 2: you know, how long can you stay up unless it 704 00:40:39,120 --> 00:40:42,759 Speaker 2: is like a large surfboard or a larger float, But 705 00:40:43,080 --> 00:40:45,759 Speaker 2: even a fair sized float can prove difficult. You're not 706 00:40:45,800 --> 00:40:46,839 Speaker 2: going to stay up there very long. 707 00:40:47,000 --> 00:40:48,560 Speaker 3: Yeah, that's another thing I want to get to in 708 00:40:48,600 --> 00:40:53,120 Speaker 3: just a minute. Balance. Now, there is another consideration, which 709 00:40:53,160 --> 00:40:57,319 Speaker 3: is the question of what exactly are you crossing? If 710 00:40:57,320 --> 00:41:01,600 Speaker 3: it's actually water, these these you know, water walking shoes 711 00:41:01,719 --> 00:41:05,880 Speaker 3: seem very implausible. But if it's some thicker substance like 712 00:41:06,000 --> 00:41:09,960 Speaker 3: a muddy marsh, perhaps increasing the surface area over which 713 00:41:09,960 --> 00:41:13,279 Speaker 3: your weight is distributed with these wooden disks actually would 714 00:41:13,280 --> 00:41:17,239 Speaker 3: give you an advantage walking over a mud flat or 715 00:41:17,239 --> 00:41:21,759 Speaker 3: a marsh, or some kind of thick, thicker substrate like that. 716 00:41:22,640 --> 00:41:24,560 Speaker 3: It might help to have shoes like this because they 717 00:41:24,560 --> 00:41:27,040 Speaker 3: would function more like snow shoes, you know, they just 718 00:41:27,080 --> 00:41:28,120 Speaker 3: spread your weight out. 719 00:41:28,600 --> 00:41:30,800 Speaker 2: This remind you know, remember we did some episodes on 720 00:41:30,920 --> 00:41:34,320 Speaker 2: mud a while back, right, and I remember looking into 721 00:41:34,560 --> 00:41:38,920 Speaker 2: like military experiments with mud and often with vehicles. But 722 00:41:38,960 --> 00:41:42,480 Speaker 2: I believe there were also some accounts of boots, like 723 00:41:42,520 --> 00:41:44,479 Speaker 2: trying to figure out like what kind of boots would 724 00:41:44,560 --> 00:41:47,840 Speaker 2: enable soldiers to move through or across the mud easier. 725 00:41:47,880 --> 00:41:50,280 Speaker 2: And I know there were at least some experiments involving 726 00:41:50,400 --> 00:41:53,520 Speaker 2: like sort of wider shoes almost kind of like snowshoes 727 00:41:53,520 --> 00:41:54,239 Speaker 2: for mud. 728 00:41:54,440 --> 00:41:56,600 Speaker 3: Right, So if you're thinking about mud or some other 729 00:41:56,719 --> 00:42:00,000 Speaker 3: kind of substrate different than just plain water, different footwear 730 00:42:00,200 --> 00:42:03,960 Speaker 3: options could have advantages. But coming back to the water 731 00:42:04,080 --> 00:42:09,840 Speaker 3: walking like literal water walking interpretation, that seems unlikely to me. 732 00:42:10,440 --> 00:42:14,800 Speaker 3: One example of these informal tests that recreated a model 733 00:42:14,840 --> 00:42:17,440 Speaker 3: of this device and tried it out was actually MythBusters 734 00:42:17,480 --> 00:42:19,680 Speaker 3: that they did an episode where they tried it and 735 00:42:19,760 --> 00:42:22,279 Speaker 3: it did not work at all. They sank right into 736 00:42:22,320 --> 00:42:25,919 Speaker 3: the water or quickly lost upright balance and toppled over. 737 00:42:26,280 --> 00:42:29,200 Speaker 3: And they even made like much more buoyant shoes, like 738 00:42:29,640 --> 00:42:32,560 Speaker 3: more buoyant, larger shoes that were different than the original 739 00:42:33,000 --> 00:42:37,960 Speaker 3: design in these Ninjasu manuals, and still had trouble staying upright. 740 00:42:38,320 --> 00:42:40,959 Speaker 3: The issue is that an adult human is just way 741 00:42:41,000 --> 00:42:45,640 Speaker 3: too heavy for reasonably sized shoe worn floatation devices to 742 00:42:45,719 --> 00:42:48,360 Speaker 3: keep them afloat, So they're not going to work unless 743 00:42:48,400 --> 00:42:51,279 Speaker 3: you make the shoes gigantic, but in doing so, you 744 00:42:51,280 --> 00:42:54,839 Speaker 3: would probably lose the ability to quote walk in them 745 00:42:54,880 --> 00:42:57,319 Speaker 3: with any kind of grace, So you're just trying to 746 00:42:57,360 --> 00:43:01,799 Speaker 3: like stand up into little canoes. And this brings us 747 00:43:01,800 --> 00:43:05,280 Speaker 3: back to the how generally floatation devices on the human 748 00:43:05,320 --> 00:43:10,840 Speaker 3: scale and larger work by displacing more weight of water 749 00:43:11,320 --> 00:43:14,080 Speaker 3: than the total amount of weight that is being kept afloat. 750 00:43:14,440 --> 00:43:17,439 Speaker 3: So you can float a thousand ton boat on top 751 00:43:17,480 --> 00:43:20,520 Speaker 3: of the water if the volume of the boat displaces 752 00:43:20,560 --> 00:43:23,239 Speaker 3: more than a thousand tons of water. Right, So, you 753 00:43:23,280 --> 00:43:25,400 Speaker 3: can have a boat made out of steel that has 754 00:43:25,440 --> 00:43:28,600 Speaker 3: a hollow hull, and even though steel is very dense 755 00:43:28,640 --> 00:43:32,239 Speaker 3: and would sink in water, it's displacing more water than 756 00:43:32,239 --> 00:43:34,120 Speaker 3: the total weight of the boat and all its cargo. 757 00:43:34,960 --> 00:43:37,560 Speaker 3: So when you think about it this way, it's relatively 758 00:43:37,640 --> 00:43:42,000 Speaker 3: easy to create a personal floatation device that will keep 759 00:43:42,040 --> 00:43:46,239 Speaker 3: you from sinking entirely under the water, because once your 760 00:43:46,280 --> 00:43:51,120 Speaker 3: body is mostly submerged in the water, it's already displacing 761 00:43:51,280 --> 00:43:54,680 Speaker 3: a lot of water. The average density of the human 762 00:43:54,719 --> 00:43:58,799 Speaker 3: body is very close to the density of water. I've 763 00:43:58,840 --> 00:44:03,040 Speaker 3: seen estimates that on average, a human adult with lungs 764 00:44:03,120 --> 00:44:06,160 Speaker 3: full of air is slightly less dense than water and 765 00:44:06,239 --> 00:44:10,240 Speaker 3: will float, and a human after exhaling with the lungs empty, 766 00:44:10,360 --> 00:44:14,080 Speaker 3: is slightly more dense than water on average, or roughly 767 00:44:14,120 --> 00:44:17,759 Speaker 3: neutrally buoyant, and will more likely sink. And this is 768 00:44:17,800 --> 00:44:23,360 Speaker 3: going to vary somewhat due to tissue composition, clothing. Literally 769 00:44:23,400 --> 00:44:25,759 Speaker 3: how much gas you have in your digestive system that 770 00:44:25,800 --> 00:44:29,880 Speaker 3: plays a role in your natural buoyancy. But as animals, 771 00:44:30,160 --> 00:44:34,400 Speaker 3: we're naturally right around on the line between sinking and floating. 772 00:44:34,840 --> 00:44:37,080 Speaker 3: So if you just add a little bit of extra 773 00:44:37,200 --> 00:44:40,839 Speaker 3: low mass volume, like a life vest, it pushes your 774 00:44:40,960 --> 00:44:44,719 Speaker 3: volume to weight ratio over the line and makes you 775 00:44:44,760 --> 00:44:47,920 Speaker 3: a little more buoyant enough that your head easily stays 776 00:44:47,960 --> 00:44:50,919 Speaker 3: above the water with most of your body maybe neck 777 00:44:51,000 --> 00:44:54,320 Speaker 3: down or shoulders down, displacing a lot of water below 778 00:44:54,360 --> 00:44:58,400 Speaker 3: the water line. But walking on top of the water 779 00:44:58,719 --> 00:45:02,240 Speaker 3: is a very different front physical goal than just keeping 780 00:45:02,280 --> 00:45:05,280 Speaker 3: your head and its breathing holes above the water line. 781 00:45:05,600 --> 00:45:08,319 Speaker 3: To walk on top of the water, you would need 782 00:45:08,400 --> 00:45:13,279 Speaker 3: shoes that by themselves just the shoe part displace your 783 00:45:13,480 --> 00:45:17,080 Speaker 3: entire body's weight in water, which again means that the 784 00:45:17,120 --> 00:45:21,200 Speaker 3: shoes need to be both light or like boat shaped 785 00:45:21,239 --> 00:45:24,440 Speaker 3: in a way with like a hollow hull and compared 786 00:45:24,440 --> 00:45:28,799 Speaker 3: to normal shoes huge. So it is not impossible to 787 00:45:28,920 --> 00:45:31,560 Speaker 3: have sort of shoes that will allow you to float 788 00:45:31,560 --> 00:45:32,960 Speaker 3: on the top of the water. You can look up 789 00:45:33,040 --> 00:45:35,960 Speaker 3: videos of people creating things like this, but again it's 790 00:45:36,040 --> 00:45:39,080 Speaker 3: just like people standing on two small boats. They're like 791 00:45:39,200 --> 00:45:44,240 Speaker 3: big things, they're not like shoes. The other issue is balance. 792 00:45:44,360 --> 00:45:47,720 Speaker 3: You brought this up rob Because of the low friction 793 00:45:47,840 --> 00:45:51,480 Speaker 3: at the interface between your water walking shoes and the 794 00:45:51,520 --> 00:45:54,480 Speaker 3: water as compared to shoes and the ground, it is 795 00:45:54,520 --> 00:45:57,759 Speaker 3: difficult to stay upright and propel yourself forward on a 796 00:45:57,760 --> 00:46:01,960 Speaker 3: floatation device. In video, it was like the MythBusters test. 797 00:46:02,120 --> 00:46:04,600 Speaker 3: When people try to do this, they quickly either sink 798 00:46:04,800 --> 00:46:05,919 Speaker 3: or just tumble over. 799 00:46:06,719 --> 00:46:09,440 Speaker 2: Yeah, you end up falling one way, and say, like 800 00:46:09,480 --> 00:46:12,480 Speaker 2: the boogie board you're trying to balance on, ends up 801 00:46:12,560 --> 00:46:14,520 Speaker 2: like soaring off the other way. 802 00:46:14,920 --> 00:46:20,080 Speaker 3: Yeah. So the misogumo as shoes interpretation for walking on 803 00:46:20,600 --> 00:46:25,360 Speaker 3: actual water seems totally not plausible. However, a lot of 804 00:46:25,400 --> 00:46:29,400 Speaker 3: this gets cleared up with a reinterpretation of what this 805 00:46:29,560 --> 00:46:33,960 Speaker 3: device was intended to be used for. So the original 806 00:46:34,040 --> 00:46:39,440 Speaker 3: text that describes this device does not describe how it's used. 807 00:46:39,480 --> 00:46:43,000 Speaker 3: It only sort of gives a give specifications of the 808 00:46:43,040 --> 00:46:46,520 Speaker 3: device itself, and shows an illustration of a single one 809 00:46:46,600 --> 00:46:50,719 Speaker 3: in isolation, notably not a pair of them. Also, the 810 00:46:50,760 --> 00:46:54,800 Speaker 3: original illustration does not indicate any kind of sandal strap 811 00:46:54,920 --> 00:46:58,240 Speaker 3: or other way of attaching the paddle in the middle 812 00:46:58,239 --> 00:47:02,400 Speaker 3: of the disk to one's foot, So some modern scholars 813 00:47:02,400 --> 00:47:05,080 Speaker 3: have come to think that this device was not actually 814 00:47:05,320 --> 00:47:10,200 Speaker 3: intended to be used in pairs as footwear, but instead 815 00:47:10,560 --> 00:47:15,120 Speaker 3: was a seat used for flotation in the water. So 816 00:47:15,200 --> 00:47:20,000 Speaker 3: a ninja could, according to this interpretation, sit in this 817 00:47:20,160 --> 00:47:22,440 Speaker 3: sort of ring and use it like an inner tube 818 00:47:23,200 --> 00:47:26,640 Speaker 3: and then float across a water remote but they absolutely 819 00:47:26,680 --> 00:47:28,799 Speaker 3: would get wet if they did this. They would be 820 00:47:28,840 --> 00:47:31,440 Speaker 3: sitting in the water, but the upper part of their 821 00:47:31,480 --> 00:47:33,719 Speaker 3: body would be sitting above the water, like sitting in 822 00:47:33,760 --> 00:47:34,560 Speaker 3: an inner tube. 823 00:47:34,840 --> 00:47:36,600 Speaker 2: So you might want to like take your pants off, 824 00:47:38,239 --> 00:47:42,920 Speaker 2: pants in your pack until you get across, climb up 825 00:47:42,920 --> 00:47:44,600 Speaker 2: half naked, and then put your pants back on. 826 00:47:45,320 --> 00:47:48,160 Speaker 3: Right, And of course all of the caveats and uncertainties 827 00:47:48,200 --> 00:47:50,759 Speaker 3: about hystericity remain. We don't know if this was ever 828 00:47:50,840 --> 00:47:53,640 Speaker 3: like really used, or if it was exactly what it 829 00:47:53,680 --> 00:47:57,920 Speaker 3: was used for. I've seen speculation that seems again just 830 00:47:58,000 --> 00:48:01,440 Speaker 3: total speculation, that you could, like, oh, you could transport 831 00:48:01,600 --> 00:48:04,560 Speaker 3: gunpowder across the water without getting it wet by using 832 00:48:04,640 --> 00:48:06,160 Speaker 3: one of these. You know, you could hold it up 833 00:48:06,160 --> 00:48:09,359 Speaker 3: in the air and float across the water. I guess 834 00:48:09,360 --> 00:48:11,399 Speaker 3: you could do that, But then again, you could also 835 00:48:11,520 --> 00:48:14,080 Speaker 3: probably just use like a small raft or boat. So 836 00:48:14,760 --> 00:48:20,400 Speaker 3: I don't think it's fully understood what the alleged benefit 837 00:48:20,719 --> 00:48:25,040 Speaker 3: of this device as described would be. But it does 838 00:48:25,080 --> 00:48:29,520 Speaker 3: seem to me that the floating seat interpretation is more 839 00:48:29,640 --> 00:48:33,560 Speaker 3: likely what the author intended than the footwear and interpretation. 840 00:48:34,200 --> 00:48:37,200 Speaker 2: I mean, we mentioned that it's important for a shnobi 841 00:48:37,280 --> 00:48:41,160 Speaker 2: operative to potentially become part of the community, open up 842 00:48:41,160 --> 00:48:45,400 Speaker 2: a business. What if that business was essentially tubing, providing 843 00:48:45,760 --> 00:48:50,040 Speaker 2: inflatable circular devices for tourists to float from point A 844 00:48:50,120 --> 00:48:53,000 Speaker 2: to point B down a river, you know, at leisure, 845 00:48:53,360 --> 00:48:56,080 Speaker 2: perhaps while enjoying a beverage. It might give you the 846 00:48:56,080 --> 00:48:56,719 Speaker 2: cover you need. 847 00:48:57,520 --> 00:49:00,319 Speaker 3: Okay, well, maybe we have to call it for part 848 00:49:00,440 --> 00:49:04,000 Speaker 3: three here, But we've got more alleged ninja techniques and 849 00:49:04,120 --> 00:49:06,640 Speaker 3: anecdotes to talk about in the next episode. 850 00:49:06,920 --> 00:49:09,319 Speaker 2: That's right, we'll be back and we'll cover we'll cover 851 00:49:09,760 --> 00:49:12,000 Speaker 2: some big ones.
