Manny, Ninjutsu and Taijutsu are one in the same. Taijutsu is simply "the art of using the body." Its the original Japanese warrior method of unarmed combat. Very practical. It employs all aspects of fighting under any given condition.
What type of Ninjutsu did you study Manny? I personally love Ninjutsu but have only spent a small amount of time studying under Bujinkan dojo. I did get to meet Steven Hayes a couple times. That was a good experience. I also had the opportunity to see Dr. Hatsumi once very briefly. That was probably one of the most intense moments of my life, just seeing that man.
