The Japan Karatedo Federation was established in 1964 to organize and oversee all styles of traditional Japanese Karate. This organization is part of Japan’s Ministry of Education, Culture, Sports, Science and Technology (文部科学省 Monbu-kagaku-shō). It is led by a member of Japan's Cabinet who is selected by Japan’s Prime Minister.
The vast majority of traditional Goju Ryu organizations are members of the JKF Goju Kai. This organization seeks to preserve and perpetuate the style of karate that was developed in Okinawa, Japan by Mr. Chojun Miyagi. Seiwa Kai USA is a member of the JKF Goju Kai.
Seiwa Kai International was founded in 1972 by Mr. Shuji Tasaki, Hanshi (1933 - 2011). He began training in Goju Ryu in 1952 under the tutelage of Gogen Yamaguchi. Tasaki Hanshi was a 9th Dan in both the JKF Goju Kai and the Seiwa Kai.
Seiwa Kai International has member organizations in more than 30 countries on all six inhabited continents and is one of the 13 member organizations of the JKF Goju Kai. Seiwa Kai USA is the national representative of the international organization.
