I was at a martial arts center that taught Ninjutsu along with some other martial arts and what one of the instructors said about the classical all black Ninja uniform is that it originated from Japanese stage workers. When they would put on performances on Japanese stages they would have people who would help with some of the stuff that had to be done on stage but that the audience was not supposed to see them and that's why they wore the all black uniforms and that its basically the same way with the Ninja, people aren't supposed to see them. Basically Ninja are supposed to blend in and be unnoticed and while the classical all black uniform might not always be the best way to do that, that's where it originated from, from stage workers. At least that's what the instructor claimed that that's where the uniforms came from.
Okay, there's a lot of things to look at here… firstly, what is meant by "ninja"? Next, what is meant by "ninjutsu"? How are you defining it as a martial art?
What I'm getting at is, in the main, the idea of "ninja" wasn't what most think of… largely, it was a job description, more than anything else, and was more spy than soldier (there were exceptions, particular groups often classed as ruppa, rappa, suppa, and so on, who had particular uses), and the most historically valid use of the term "ninjutsu" refers to a skills set relating to espionage, information gathering and so on… not combative skills. The idea of a set of combative skills (martial techniques) being what is meant by the term "ninjutsu" is really a fairly modern take on things.
That said, yeah, the idea of there being a "ninja uniform" is largely a product of popular culture's creation, rather than historical fact. One such source for the inspiration of the image of the "classical" shinobi shozoku (the hood, the gauntlets, the tied-in hems on the hakama etc) is the set-dressers of Noh and Kabuki theatres (as well as the puppeteers for traditional puppet shows), which would be deemed "invisible" by the audience. That, however, is not the entire story.
There are a number of ukiyo-e (woodblock prints) from the Edo period that show what we would easily recognise as a "ninja outfit" in use… commonly to show that a particular character was a thief, or at least, acting like one. In this regard, it's similar enough to the popular Western movie habit of showing thieves in balaclavas, black skivvies, and so on… it doesn't mean that that's what they wear, but it's a popular enough image to pervade the zeitgeist. Then again, an equal number identified "ninja" characters without such costumes… there are images of "ninja" characters from popular Noh dramas and Kabuki plays which see them dressed pretty much like everyone else.
To clarify - this is the origin of the ninja uniform as seen in TV and movies. It's not something that was worn historically.
Yep.
So the all black dogi and tabi shoes look that seems to be popular in ninjutsu circles is ahistorical? Who started it?
Of course it is, ha!
Who started it? Well, tabi have been standard footwear for Japan for centuries… and many traditional Japanese arts continue to train in them (I wear them for a range of things I train in, with them being prescribed for Kyudo, for example). The modern jika-tabi (outdoor versions, with rubber soles), are really common workman's boots, providing a fairly comfortable, light footwear with excellent grip. While traditional arts (being trained indoors on tatami-mat dojo) don't utilise them, they became relatively popular in the Bujinkan in the early 80's, mostly with Western practitioners. Personally, I feel that this was more to do with a connection to the actual footwear worn in Japan (naka-tabi, the regular, soft soled version), combined with the fact that much of the early training was done at outdoor seminars, and that's what Hayes chose to wear at those events. These days, indoor tabi are far more common in ninjutsu circles.
As for the black uniforms, that's largely down to Hatsumi. When training under Takamatsu, they wore a white do-gi, just like many other arts… it was only later that Hatsumi changed it to a black one. Whether to better fit the popular image, or to reduce the staining on the uniforms in outdoor training, you'd have to ask him…
Well that's what the instructor said, that they classical black ninja uniform when they trained and that it is what's portrayed in movies but in reality ninja would dress and act however they could in order to blend in and be unnoticed. That of course would depend on the environment and the situation. And yes, supposedly solid black isn't good for blending in, even in dark conditions as it tends to leave a silhouette. Supposedly grey or dark blue is better.
Okay, I just want to clarify something here… you talk about the "classical black ninja uniform" being worn in training… does it include the headgear, sleeve gauntlets etc? Or is it more just a black karate-style gi? The reason I ask is that, well, if it's the former… then the person you're talking to is most likely a member of one of the fraudulent groups… no legit organisation has that piece of theatre garb as it's uniform… so I wouldn't take anything they say as definitive or correct… most of what they might get right would likely be more from reading more authentic sources, rather than anything in their own understanding. So you know…
Did they do ninja in stage? When did it become a popular culture thing?
During the Edo period… some 300 years ago… at least…
