The International Shudokan Association was founded by karate-ka who can prove direct decent from a Shudokan Shihan personally designated as such by the founding master, Toyama Kanken. The association has grown to nearly twenty thousand members since its founding in 1975.
Membership is open to all practitioners of Shudokan world wide who want to reaffirm their style.
It has become clear in recent years that the many karateka descended from Kanken Toyama have been overshadowed by the contemporary organizations because of the lack of organizational unity. We invite all Shudokan practitioners to add their name to our membership and to once again show the martial art world that their are more than the four styles promulgated by the sports governing bodies.
