About Seishinkai
Seishinkai grew out of the Seishinkan Okubo Dojo, founded in 1986 after the passing of the first Soke (originally the Seishin-ryu Karate Sapporo Branch, established in 1976 under Branch Chief Katsumi Okubo). In February 2004 it was incorporated with the approval of the Governor of Hokkaido, becoming Hokkaido's first registered non-profit (NPO) karate organization.
Official registered name: Specified Nonprofit Corporation "All Japan Seishinkai". Activities include karate classes, international exchange, and support for karate exchange students.
※ We also host long- and short-term international karate students, and offer karate and iaido experiences for visitors from overseas.
