In 1990, Gozo Shioda founded the International Yoshinkan Aikido Federation (IYAF) to facilitate the learning of Yoshinkan aikido outside Japan. Under current dojo director Susumu Chino, the Yoshinkan hombu dojo, located in Shinjuku Tokyo, runs an annual 11-month intensive course called the Senshusei course, in which students from Japan and foreign nations train with the Tokyo Metropolitan Riot Police. The book "Angry White Pyjamas" by Robert Twigger is based on the author's experiences during the course.
