While many taiho-jutsu methods originated from the classical Japanese schools of kenjutsu (swordsmanship) and jūjutsu (unarmed fighting arts), the goal of the feudal police officers was to capture lawbreakers alive and without injury.
[1] Japanese law enforcement officers trained in self-defense and arresting techniques primarily based on the unarmed fighting styles of jūjutsu.
Japan was being demilitarized, the practice of the martial arts had been prohibited, and the Japanese police force was unable to cope with the outbreaks of violence during that period.
[5] Taiho-jutsu was introduced to the U.S. when the Strategic Air Command began sending combative measures instructors to the Kodokan in Japan for eight-week training programs.
To promote more effective arrest and control and defensive tactics training methods, Daniel Hect led a committee of law enforcement and military trainers as well as leading martial artist in reviewing the techniques from traditional taiho-jutsu, Goju karate, Japanese jujutsu, Brazilian jujutsu, and aikido to develop a comprehensive Arrest and Control curriculum that could be used in the field today.
All techniques taught in the Shudokan Ryu, Taiho Jutsu system are in compliance with the California POST, Use of Force Standard; and are the foundation for Arrest and Control/Defensive Tactics curricula.
Techniques not applicable to current law enforcement methods were omitted from the Shudokan Ryu, Taiho Jutsu curricula to limit the potential of excessive force liability.
