Masaaki Satake
When Ashihara left the IKO a few years later, Ishii followed, but then left Ashihara's organization after only a few months. He founded his own organization, Seidokaikan Karate, in 1980. Ishii's organization had "dojo" in the Kansai region. Within the next two years, he was promoting televised full-contact karate tournaments. In 1983, Ishii became the first Chairman of the newly formed All Japan Budo Promotion Association. Seidokaikan's reputation grew as Ishii's students, such as Masaaki Satake, Toshiyuki Yanagisawa, and Toshiyuki Atokawa, earned tournament victories.
