Our Organization

RSKKR is an international organization created on October 1, 2008, with the approval of Shian Toma Sensei. It is modeled after Master Toma's original organization, the Zen Okinawa Seidokan Karate Kobudo Renmei (ZOSKKR). At the request of Master Toma's family, ZOSKKR was officially retired on September 26, 2013. We are the headquarters, here in Okinawa, in the service to all of Shian Toma's karate descendants who actively train, preserve, and propagate the art of Okinawa Seidokan Karate worldwide. Through the efforts of many RSKKR (former ZOSKKR) Senior Leaders, Okinawa Seidokan is practiced in many countries. As of October 2025, RSKKR is a standalone organization.

The goal of this federation is to maintain high standards throughout all RSKKR dojos, propagate Okinawa Seidokan internationally, and improve individual lives and communities through our martial arts way.

The Honbu manages the administrative recognition and certification of RSKKR members and sponsors international Okinawa Seidokan karate events. Stay strong,
