Hello, I'm interested in training in “real ninjutsu” – stealth, espionage, infiltration, making weapons and tools, urban and wilderness survival, tactics & strategy, combat and esotericism. I'm not interested in being around dudes in black gis practicing hand-to-hand combat – I'm convinced that this is a totally bogus modern distortion of ninjutsu. So...does any such thing exist? Do any existing “ninja schools” teach this stuff? What I've seen of Bujinkan doesn't look very interesting. I'm visualizing some kind of "Jason Bourne"/Violent Nomad training with a bit of Eastern philosophy and mysticism. I wonder if there is a market for such a thing? Do you really think ninjas practiced katas all day? Doesn't what I'm talking about sound more interesting?
