I get what you're saying, and in general agree with it. People see the word ninjutsu and think it's something it's not (and I would not be surprised if that's done intentionally, or even marketed that way). I just wanted to make sure OP knew that the style itself could still be legitimate, even if the name of the overall style is misleading.
That cool as I said what is being taught I do not know and as you say it could be quite effective and the teacher could and probably is very genuine.
It was and is a marketing style and that grew from the Ninja boom era of the TV and Movies and it was and still is to some extent a money maker. It just always makes me cringe when I here that word and then anything tagged onto it. There is no doubt that Ninjutsu existed but as a Martial Art alone it really did not and it was most certainly not a hand to hand combat art ... Yes some of the "Ninja" were from more humble backgrounds but then some again were Samurai and Ninjutsu was taught in the schools that the Samurai studied in ...yes all be it only to a select few but it was not some mystical underground all defeating art and there was no taijutsu at all lol
