To offset the post-war catastrophic context in Japan, Yamaguchi chose to transmit and pass on the new generation this art of life that is the way of karate (karate do), to inspire in them the will and courage to rebuild. Thus, he creates the “All Japan Karate-do Goju kai” (JKF), in the early Fifties… Among his best students: Shuji Tasaki.
In 1971, with the approbation of Gogen Yamaguchi, Master Tasaki starts his own karate association, the Seiwakai, to regroup a large number of karateka from all over the world.
After Gogen Yamaguchiʼs death in 1989, Master Tasaki is the leading Goju karate instructor in Japan. Until his death in 2011, he will continue to give seminars on all five continents, together with Seiichi Fujiwara, his best student and future successor.
Today, Master Tasaki stands in the mind of most as the ultimate model of the karate master, both grounded in tradition (from the time karate was strictly Japanese and closed to women) and open to modernity (open to the rest of the world and to women).
