James Mitose, a Japanese American martial artist, is credited with bringing the art of kenpo to the United States in 1936. Brilliant but controversial, he left an incredible mark on the art’s development in America.


His legacy was marred by a criminal conviction — one his family continued to dispute. In 1974, he was found guilty of murder and extortion, sentenced to life in prison, and died there in 1981 from complications related to diabetes.

During his time in prison he was visited by kenpo master Bruce Juchnik who chronicled his teachings.
Mitose's son Thomas Barrow Mitose said in a 1992 interview with Black Belt, that his father got a "bum deal from the American legal system and from some of his disciples."
