In 1989 Taiji Kase together with Hiroshi Shirai founded the World Karate Shotokan Academy (WKSA), in order to educate people in karate as a martial art and way. During the past 12 years Kase sensei has taught in many countries the Shotokan Ryu Kase ha, the way of karate he has developed through his diligent practice of the art, for more than 60 years. In 2001 senior instructors, who followed Kase sensei all those years, have decided to proceed, under his direction and guidance, with the foundation of the Shotokan Ryu Kase Ha Instructors Academy (SRKHIA), with the aim to preserve and further develop the Shotokan Ryu Kase Ha Karate-Do. Unfortunately Taiji Kase Sensei died in 24th of November 2004.
In case of this idea the group of close students from Taiji Kase Sensei build up at 13th October 2007 an international organization which is recognized by the family of him as the original representation of his karate. Kase Ha Shotokan Ryu Karate Do Academy (KSKA) is now the frame in which we keep and develop the ideas of our Master.
