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. The
course was a Japanese-designed mix of Judo, Karate, Aikido and Taiho-jutsu. Kodokan officials contacted the JKA to manage the karate instruction. The JKA responded by sending Nishiyama,
Obata, Okazaki, and Terada. Judo instruction was provided by Kodokan greats Kotani, Otaki, Takagake, Sato, Shinojima, and Yamaguchi. Aikido instruction was led by Tomiki, along with
Yamada and Inuzuka, while the instruction in Taiho-jutsu was given by Hosokawa and Kikuchi.
