Yoshinkan (養神館 Yōshinkan lit. "Hall of Spirit Cultivation") Aikido is a style of aikido that developed after World War II in the Yoshinkan Dojo of Gozo Shioda (1915–1994). Yoshinkan Aikido is often called the "hard" style of aikido because the training methods are a product of Shioda's grueling life before the war. Shioda named his dojo "Yoshinkan" after a dojo of the same name that was built by his father, a physician, who wanted to improve both physical and spiritual health. The Yoshinkan style is currently the second largest aikido organization worldwide.
