This video was brought to the attention by a friend of mine who wanted to know if this was legitimate ninjutsu, because he felt it had a lot of Kali-feel to it. I've had the opportunity to train in a bit of Jinenkan and Bujinkan tantojutsu and tantodori, as well as teaching JKD Kali and trained in Inayan, Pekiti Tersia, & Serrada Escrima. Here's the video he sent me. http://youtu.be/zvn3Zgctc2A For comparison, here is what the Takamatsuden kata that Bujinkan tantojutsu is based on look like: http://youtu.be/7XVVsN6GEkI Evidently, the instructor in this video, Shihan Dean Rostohar, is stating that all this material is Bujinkan, and doesn't have any Kali or FMA influence. Here is another video of Shihan Rostohar teaching knife. http://youtu.be/7ElC1eKlJcI And here is another video of orthodox Takamatsuden tantojutsu kata. http://youtu.be/fEtz6nFHkGk What are your thoughts on this? Is there a clear FMA influence?
