Seishinryoku Jujitsu consists of "unarmed and armed" self-defense struggles developed by the Samurai warrior in the battlefields of Japan's feudalism


Seihinryoku Jitsu is not a competition martial arts sport – but, rather a martial arts system designed to provide highly effective techniques and training for real life self-defense needs.
