To-Shin Do is a martial art founded by Black Belt Hall of Fame instructor Stephan Kayes Haes in 1997. It is a modernized version of ninjutsu and differs from the traditional form taught by Masaaki Hatsumi's Bujinkan organization. Instruction focuses on threats found in contemporary western society. In addition to hand-to-hand combat skills, students are exposed to methods for survival in hostile environments, security protection for dignitaries, how to instruct classes and run a school, classical Japanese weapons, meditation mind science, and health restoration yoga. The headquarters school (Hombu) is located in Dayton, Ohio, USA.
So, it is related to ninjutsu, but it is not ninjutsu.
