Kudo (Daido Juku).
Kudo is a martial art created by Azuma Takashi in 1981. Azuma was a black belt in Kyokushin Karate and Judo, saw the potential for a hybrid martial art which was not limited by styles. He decided to merge the two martial arts he knew, and made Daido Juku, where striking and grappling was allowed. Slowly, various other martial arts like Muay Thai, Boxing, Jiu-Jitsu and various other martial arts were incorporated, and fine-tuned to work well in the style. The martial art was renamed as Kudo in 2001, and is accepted as a Budo sport in Japan.
