[@davetaylor2088]

In the 80's when I was going to high school, ninja was the single most talked about thing. We watched the movies, read the books, played role playing games, and tried to make the weapons in metal work class! Some time after that I found an excellent book that outlined some of the suspected tactics and history and much of it matches with what you said here. One of the theories about the sword was that it was small and straight to make it easier to conceal inside a robe. Even though I am (obviously) a lot older now, I still find these aspects of Japanese culture and history fascinating and your videos are very well presented. Arigatoo gozaimasu, sensei.

[@denischen8196]

Metal work class in high school?! At my high school, there was no such thing as metalwork or blacksmithing classes.

[@Qba86]

From what I understand, shinobi/ninja was more of a function on the battlefield, that focused on scouting, espionage and diversion. Both samurai and ashigaru could act as shinobi, and the "ninja clans" that are often mentioned were simply minor samurai clans that specialised in shinobi tactics.

[@houseofaction]

correct, actual ninja scrolls found and translated make no mention of assassination, or combat they make mention of nothing but spywork

[@lessavini]

Makes sense, specially when you consider they came to prominence during a time of civil war. That said, there's evidence they assumed a role of "special police" of sorts during early Edo period/Tokugawa shogunate, though. But it's hard to say if they already had some expertise in this field or simply adapted to a new role.

I remember when I studied "Ninjutsu" 26 years ago a couple of Sensei arguing about the existence of the Ninja-to. If they did exist there may be some reasons why they disappeared. 1)The quality of a Ninja-to would have been substandard and the rusted remains would have been recycled due to a shortage of metal. 2) No swordsmith would put his stamp on an assassin's weapon and it's legality would make it something to be disposed of. 3) Quality Katanas were treasured and passed down through generations with the Honjo Masamune being like "Excalibur". 4) Ninja-to would have been used as evidence and therefore disposable. 500 years from now there may be a museum housing guns and bayonets but I doubt anyone will keep an old zip-gun or shank.

[@SniperAngle12]

Funny you should say that because the royal armoury museum does have various examples of zip guns and other homemade firearms. Shanks are also often preserved as an example of improvised weaponry in adversities like prisons or POW. Also, for sure most of these ninjato would've rusted away since they wouldn't have been cared for like katana, but just think about how many katanas have been found hidden away in attics, and why haven't there been even a single example of a ninjato like there are shuriken and kusarigama and etc? Given that the shuriken are even more disposable than a short sword, and are often intentionally rusted to induce tetanus in the victims, it's a wonder that there exists no ninjato to be found when shurikens are.

[@Max-ec3xi]

I've also heard of a theory that they would keep a short sword (curved like a uchikatana) in a standard size saya, to blend in during espionage and so they have space to effectively hide poisons in the bottom of the saya. There are so many theories and it's all super interesting!

[@victorribeiro2431]

Shogo... Some historians believe that the shinobigatana was a mix between the Daisho. So you take the longer tsuka and saya from a uchigatana and place than into the shorterblade of wakizashi. So you have a saya that is long enough to carry medicine and blinding or burning powder a longer handle to make it more stable and a shorter blade usefull in assassination and CQB and to trick enemies in 1-on-1 combat.

[@Warjah104]

There is no such a thing as Shinobigatana nor Gatana. It’s called Katana. Secondly there were no Ninja/Shinobi swords in feudal Japan. Historical fact.

From all my years of study and attending a Bujinkan Camp as a youth as well as personal book/historical studies. It seems like the Ninja took part in many different roles on the battlefield and warfare throughout Japans history. Very interesting history and the fact that some scholars say their (Ninjutsu) roots also come from china is very fascinating. Great Video! OSU!!!!a As a side note, everything I have learned stated that the swords we know as Ninjato were made very cheaply because of the fact that they were used as a tool. Its easier to create a straight sword then a curved one such as a katana. I believe that if a "Ninja" had the opportunity to pick up a Katana on the battlefield they would either for Monitory gain or the fact that they perform better in combat. That being said, there is some historical data that some of the smaller Samurai family's from the Iga region actually became what we know today as ninja. And I assume that their family historical Katana's followed suit. But of course their role is so shrouded in hearsay and history. Its hard to be conclusive on some facts and if their is any historical fact or if its fiction

Even if it didn’t properly exist, I think the distinction in attitudes toward the swords is fascinating. The way samurai tie them to faith is something I guess I’ve noticed but haven’t put together until now. Samurai always seemed more careful but I thought it was just for the sake of being a professional. I wonder if some ninja felt there was religious significance but just didn’t have the time to respect it in the middle of a mission. That would be pretty mentally strenuous

[@shawnmatthews5118]

The ninja gattana were heavy thick blades meant for chopping and stabbing. They were made, crudely, by blacksmiths who were oriented toward producing farm implements and, many of the weapons associated with ninja were, in fact, farm tools, such as the kama. As you pointed out, most ninja carried katana, most likely taken from samurai they’d slain. These swords were sometimes customized to have shorter blades, making the draw faster, while keeping the length of the saya long to present the illusion of a longer blade.

Finally got a chance to be the third commenter. Shogo I love your casual way of conveying topics 😍 Wait a minute, am I mistaken? The seven types of katana you mentioned aren't actually katana. They are the weapons of the samurai.

[@blazinkid5178]

Technically, they are... but also aren't (well except the yari, sorry Shogo but this should be substitued for nodachi or tsurugi). The kanji for katana is present in all of these weapons; they can also be built through some derivation of the katana (naginata is literally katana + pole for example).

[@fernandopires135]

The non-curve of the blade is the main thing that makes ninja swords look like fiction The curve of the katana is a natural byproduct of its forging... I find it very unlikely that people would develop a new forging process for such a small part of a ninja's kit If I had to put money on it, i'd say that ninja used normal wakizashi with modified shieths

[@gladehartdreamer5620]

well, there are many things that were invented by ninjas and not revealed to anyone else, you could call those "ninja technologies" wich they kept to themselves, also straight katana were invented eventually, so its not unreasonable to assume that ninjas might have invented them sooner but not revealed the secret of its production to outsiders.

[@Chemist2013]

It’s so well organized and didactical, awesome work!!

[@jaredwishart3403]

Shogo, I appreciate your balanced approach on any topics I've heard you talk about! Very enjoyable. Here's a thought that I heard once from a martial arts teacher of mine: at certain times in Japanese history, only samurai were allowed to carry katana. If a ninja was not also a samurai (some were), he would have to either steal or scavenge a sword. So he theorized that the idea of straight swords used by ninja came because of scavenging bad quality or failed swords form swordsmiths (who he theorized would have thrown away blades that ended up being straight at the end of forging). It's an interesting theory at least.

[@lavayuki]

I did not know Ninja were related to swords. I thought they just used Shuriken, Nunchaku, small throwing knives and kunai. I quite like the idea of Ninja more than Samurai from anime and video games. Wakizashi reminds me of Yojimbo in FFX

[@Maryland_Kulak]

Nunchaku were Okinawan. Ninja did not use them.

[@JohnSmith-zk8xp]

Because some people say that a ninja isn't just a samurai or former samurai engaged in syping or guerrilla warfare.

[@EthosAtheos]

The curve of a samurai's sward is imparted during the heat treating process. The differential hardening employed causes the blade to curve. This method of hardening makes for a very complex blade. But it has the down side of causing a higher rejection rate due to warping or cracking. A blade that is not differentially heat treated is easier and less likely to have issues during the heat treatment. This would make a blade that was not differentially hardened much less expensive. It would also make for a blade that isn't as strong or perhaps is as strong but not as sharp or that dulls more quickly. Depending on how the blade was tempered after the heat treatment. So, it isn't just that a straight blade is straight it is about why the blade doesn't curve. I would imagine given the low quality of steel available to smiths in Japan. That both blades would have been made of layers of forge welded steel. Unless a trade route form the main land brought in other steel. I am not an expert in Japanese history or swards but I am a smith.

[@krishnan-resurrection714]

i take it it is easier to mold a straight blade than a curved katana ...this in itself would give a little credulity to the idea of a straight-bladed 'ninja' weapon ...-make a lot easier for the "peasants" to come by anyway ....

[@EthosAtheos]

@@krishnan-resurrection714 Swords are not molded they are forged. Molds are used in casting. Casting isn't usually used to make blades. Parts of a weapon are often cast but I don't know of any cast blades. As far as I know all japanese blades are forged. It isn't about the difficulty of forging a straight blade vs curved. All katanas start their lives as straight blades. It is the differential hardening that imparts a curve to the blade. The differential hardening imparts a Hamon line as well. If you differentially harden a long blade like a katana. You have a higher risk of warping and cracking the blade. But you get a better quality, more complex blade. The alternative is edge hardening. Where you heat just the cutting edge up and quench it. Edge hardening does not curve the blade. One advantage to edge quenching is you can have a lower rejection rate due to cracking and bending. I've only made a few blades, about 1 in 3 will crack or twist to the point of being unusable and me having to start over. Again I don't know why ninja swords were straight. But that is was straight might reveal differences in how it was made. Also that it is straight might come from cost savings from differences in production. But both of those are inferences.

First, wonderful information Shogo. Second, in modern "Ninjitsu" training most ninja were disguised as gardeners and peasants to obtain information and the "weapons" used were literally garden tools....like hedge clippers. As a Combat/Survival instructor I have even incorporated this concept into my training program and I teach and recommend students to purchase/practice fighting with hedge clippers. A preferred set of clippers I've purchased from Lowe's home improvement that has forged blades 20" to 24" blades and an extendable handle giving a combat reach of over 36". The clippers are excellent for thrusting attacks both closed or open and excellent for blocks and to parry oncoming attacks. Another weapon that gave Ninja "supernatural" were scaling or climbing claws that they doubled as a measure to block sword strikes. I've only known hollowed out bamboo or reeds as as snorkel...sorry about that. Ninja were also proficient chemists and in documentation I've studied they even developed gas weapons derived from yellow cow poo and flamethrowers. Swords by my understanding were rarely used the straight sword w/square hilt doubling as a step ladder, as you described was the same as I understand it to be used for stabbing and hacking. The Ninja would also use a fallen adversaries weapon as well as Ninja were trained to capitalize on any opportunities presented. Amphibious attacks were also devised w/flotation devices allowing Ninja to cross lakes and bogs. Undoubtedly, swords were weapons utilized by Ninja and adaptability is the key trait that Ninja embraced the most and everything the Ninja used were multifunction tools allowing for them to complete their mission. In my research it was said that the last Emperor of Japan hired all Ninja clans as secret bodyguards posing as gardeners and attacking any would be insurrectionists that might threaten the Emperor. Finally, Ninja were adaptable and to avoid being wiped out, by outlawing them, they are said to have either gone silent or immigrated to other nations i.e. USA. Again thank you for your sharing your information and your study to the Combat Arts.

[@Qongrat]

Just a note - straight Japanese swords were the norm before 980AD. Straight bladed Japanese swords are referred to as chokutō. There are quite a few ancient blades surviving in the museums and shrines to this day and they look exactly, especially the later ones, as the "ninja sword" blades (not sure about the fittings: guards, sheaths and etc.) Curved bladed swords in Japan did not come into popular use until somewhere around the middle of Kamakura period around 1100s. A katana, only one particular and quite specific style of a Japanese sword out of many, usually worn tucked in a belt with the edge facing up, is actually quite a late development. It was initially used only by ashigaru (common folk light infantry) and later adopted as a more practical style of sword by samurai class who had mostly used a longer more curved tachi swords, that were worn with the edge facing down suspended from a belt and quite well adapted for horseback fighting but not as practical on foot as a katana. Japanese spies - historically known as shinobi, probably used whatever they needed and had depending on their class, including samurai. For certain spy jobs you needed an actual samurai for other spying jobs an actual monk, as pretending to be one would not always do, while for others merchants, peasants and prostitutes and even criminals. They were all known as shinobi. Spying was a task not a social class, though some clans like Koga and Iga later started to hyper-specialize in spying task specific skills. A stereotypical "ninja" character clad all in black is an invention of a Japanese entertainment and popular fiction of Edo period and aesthetically is modelled more on kuroko { 黒衣 }, traditional Japanese stagehands, not the real shinobi.

@@whateverwhatever4476 Also, these supposed Japanese martial arts historians you see all over KZbin are complete boneheads. I've come across a ton of historical records (not densho) that refute most of the nonsense they claim. I have studied Takamatsu's claim that all samurai bujutsu traditions stem from the Tendai temples of Shingon Buddhism and it appears to be completely legit. They were called Sohei. These warriors were those mysterious bodyguards that they claim eventually became samurai. I can further break down this history, but it will get very long-winded..

Glad to see this channel . I have several Japanese friends and I think this channel will help people understand and be closer together. Just being friends can bring cultures so closer together. And see we're all different and we're all alike.

Hello, it's Tristan, I been a martial artist my whole life and been deep into japanese as well as other asian cultures. I believe that the ninjatos would be fine at slashing with no problem, I like seeing leonardo tmnt with ninjatos instead of katana, my favorite sword was johnny's in Surf Ninjas it was a long handled philipino style sword. I'm going to recreate TMNT in my own better style, I want Leonardo to use an average length Ninjato and also have a companion sword, a twin if you will, but with the blade about only slightly less than half the length of the other but with the hilts the same everything, and he will wear bolth sheeths on his back with the smaller on top . Thanks remember NINJATO'S are the future whahahahah

[@Grauer1963]

Thank you for your very special kind of explaining things of the historical stories about Japan and Japanese traditional culture. And this in a very good pronunciation....very good to understand for me ;-)...and now I`m a subscriber too. Regards from germany and stay healthy.

I understand that feeling when you start collecting Katanas. Got 7 Katanas, a Wakizashi and a Tanto and I still want to get an Odachi, a Yari, a Naginata and a Kanabo

[@HereWeAre52]

Very INTERESTING theory. Very compelling argument.

[@Dethneko]

That sword seems too well designed to have existed during the time of the ninja. It's been suggested that the curve of the katana was NOT a design choice, but a byproduct of the cooling process due to the forging options available during the age of their creation. As such, it seems likely that a straight katana for a ninja would be a literal impossibility. It was always my understanding that ninja used the tools available to them. Things like the kama and sai, while great for farming, were terrible in combat. However, these are what the average peasant had available, and in a time of necessity would surely figure out a way to use it somewhat effectively. That said, it was more guerilla tactics they employed to catch the samurai off guard as that was the best chance they had at defeating them. As such, any katana a ninja had would have been taken off of a samurai, and considering how sacred the katana is to the samurai, it was most likely taken off a dead samurai. As I understand it, "ninja" basically translates to "spy" which not only suggest they can still be active today (similar to the American CIA or Russian KGB), but even at the time they'd do their best to blend in and look like everyone around them. To this effect, the outfit we associate with the "ninja" did exist, almost. Rather, the "modern ninja garb" is based off of what the ninja wore in the period, which is what everyone else wore around them. If the ninja was the only one wearing that garb (including the face covering) they'd stand out, but if 90% of the populace is wearing the same, then they look like everyone else. I don't know how much (if any) of the above is true, but it does feel like most of "ninja weapons" are only used by the "modern medieval ninja" which is to say modern weapons optimized for use by feudal "ninja" in anime, manga, and video games.

In the 60's in Hi. On Saturday morning we watched the White Samurai. He was blind,and never lost a battle with any bad guy's. Thanks for the update and entertainment.

[@rudyantohosalim2753]

What's the point of having a weapon specially made for undercover spies? In this case ninja🤔... It's just make it obvious that they are spies...

[@Rvoid]

Which is also a solid argument against shuriken. A kunai, however, is plausible because it is more of an agricultural tool.

[@kaijuslayer3334]

@@revbladez5773 No one used it. Fantasy weapon. Any “real shinobi” weapons that actually were used in real life, are all improvised farming weapons. But a throwing star is a custom built battlefield weapon. It has no main non combat use like a kunai. So it’s practical existence is not likely

[@The_True_]

The sword would most likely be for battlefield recon and "surgical strike" missions, rather than undercover espionage.

[@erikmilburn51]

That was a very practical lesson and makes a lot of sense...take care always

yeah, if they need to use katana, they would just use a regular one.

In fact, the ninja sword, being in the scabbard, was no different from the samurai sword. The only difference is the shorter blade - hence the straighter curve of the blade (the scabbard had the same curve, although the length of the blade was closer to the wakizashi). The intended purpose of such a sword is "work" in enclosed spaces, stabbing blows, speed of reaching, longer scabbards could be used as a case for ... A square tsuba was made only when there was a need to forge several swords as quickly as possible, usually this could occur immediately before some task, although in the future the same swords could be used (but only during sorties). Using a tsuba as a step, if desired and dexterity, could not only be square. So we can talk about at least four types of swords (in terms of the blade) that the ninja used: samurai katana, wakizashi, samurai katana with a shortened blade and ninjato for special tasks ... As for whether a ninja could carry a sword behind his back - then yes, they could (of course, this mainly applies to a short sword). There were special techniques for drawing the sword from behind the back in different positions, also under certain circumstances the sword could be displaced, for example, when somersaulting, the sword could be pulled to the chest and stomach ...

Scorpion also used a Ninjato in the Mortal Kombat series. He first wielded an ordinary Ninjato in Deadly Alliance. He wielded a modified version in Deception and Armageddon, with a sharped tsuba and a tiny spike for a pommel. He used 2 Ninjato swords in MK9, they have a similar spike pommel but also with a serrated blade. And in MKX, Scorpion's Ninjato swords adopt an almost European look for the handguard.

I entered a rabbit hole of japanese culture and I'm glad I found your channel

[@benwills4122]

I am really enjoying your videos Shogo! I have practiced Ninjutsu since 2008 and what I have learned is this. There are a number of plausible theories all of which could be true. The idea of the "Ninja" sword both in appearance and association may come from the Togakure Ryu style sword which has a longer Tsuka and shorter blade which appears straight but is slightly curved, this is still held in a full size Saya giving the impression of a long sword but allows a quicker draw against an opponent due to the shorter blade. Another theory and style is that the ninja clans were not set up to make refined blades and therefore the finished Katana would have had a different, perhaps less of a curve and duller edge. Within the sword school there is a method of actually using your body weight to push/drag the sword across the opponent as they are not as efficient when cutting. The Ninja also armed themselves with what ever they could find/take from opponents, shuriken were derived from the wheel hubs of carts for example, their swords may have equally been taken, modified or repaired which would change their appearance. Just my thoughts on what I have experienced so far but as you say, who really knows and could we ever really know for sure....

[@juju0K_]

Teach mean

[@eddiejravannen]

I read some where that some ninja swords were just wakizashi blades with katana handles and scabbards. This was supposed to give them a faster draw and surprise their opponents.

[@Tenken89]

[@jojoowens9309]

Great educational video,, my stepson is obsessed with Samurai, so since I'm into filmmaking, I have been searching for certain types of clothing besides the heavy armor for him, he is wanting to make a short film as a Samurai. Thanks again and look forward to more of your videos.

[@blackseed68]

Great video shogo I'm a big fan. In regards to there being no ninja swords I often hear that over generations, stories about ninja have been exaggerated. One theory is the most fantastic myths were perpetuated by the ninja themselves as a clever tactic to hide their abilities. All of the mysticism surrounding ninja (flying, jumping off buildings, running on water, dissappearing in smoke) were actually skillful implementation of tools and gadgets. The way you described their use of the katana as a stepping stool reminded me of this. It is a shame there isn't more documented proof tho 🤷🏿‍♀️
