This man claims a Ninjutsu lineage, but also Bujutsu including Jujutsu/Yawara (hence I posted here). Not many know of him still as he is reclusive. His name is Jinichi Kawakami and he was just appointed as a professor at Mie University in Japan to teach his expertise in espionage, relating it to business. Here's the article from Japan's leading News Network, Kyodo News: http://english.kyodonews.jp/photos/2012/02/139408.html Here's a video of his very "intense" training: [ame="http://www.youtube.com/watch?v=iGOGl1JsJW8"]Endureciendo Nudillos - YouTube[/ame]
I think you'll find Mr Kawakami is rather well known online. Just do a search of MAP and you'll not only see mention of him but also whole threads about him.

LOL Around 4:30 they say in their opinion Ron Duncan was much more reliable source of ninjutsu. That says lots about the makers of the video. And the people they are talking about.
He came and did a seminar in the states a while back. There was some weird weapon stuff with these giant rings. The video is still up on youtube somewheres.
