Yoshinkan

Aikido Yoshinkan (合気道養神館 Aikidō Yōshinkan lit. "Aikido Cultivating the Spirit School") is a style of aikido founded by Gozo Shioda (1915–1994) after World War II. Yoshinkan Aikido is often called the "hard" style of aikido because the training methods are a product of the gruelling period that Shioda spent as a student of Morihei Ueshiba before the war. The Yoshinkan style is currently the second largest aikido organization worldwide.
