Dillman is just a showman of the true masters of the art. I have had the opportunity to train with S. Oyata and various other Masters in Okinawa. I can say that Kyushu Jutsu and tuite are for real. It takes a great amount of practice and study. We CAN NOT learn them from video, books, or any other form of literature. Only with a true Master of the Arts. I was told there are three plains of the Martial Way. First we kick and punch, then we advance to Kyushu Jutsu, lastly we attain tuite, the true underling study of Bushido. I am in no way downplaying any art, system or belief just expressing my 30 years of experience.
