Does anyone know anything about the aforementioned Ninpo instructor? He used to have a studio in Mentor,Ohio. From my understanding he is a fairly high ranking black belt. He specialized in the tie up area, i.e. restraining techniques. I believe it was mentioned. That he was a long time instructor to the Tokyo Police. I had occasion to speak with him a couple of times, and he seemed very agreeable. I'am just asking out of curiosity. No agenda in mind.
