Senshusei Course
In 1990, Gozo Shioda founded the International Yoshinkai Aikido Federation (IYAF) to facilitate the learning of Yoshinkan aikido outside of Japan. Today, both the All Japan Yoshinkan Aikido Federation and the IYAF are now led by the current head of the style Yasuhisa Shioda, the founder's son. Under him, the Yoshinkan Honbu dojo, located in Shinjuku Tokyo, runs an annual 11-month intensive course called the Senshusei course derived from the course used to train the Tokyo Metropolitan Riot Police. The book Angry White Pyjamas by Robert Twigger is based on the author's experiences during the course.
