Yoshinkan (養神館, Yoshinkan, lit. House for Cultivating the Spirit) is a style of Aikido founded by Gozo Shioda (1915-1994) after World War Two. It is occasionally called the hard style because the training methods are a product of the gruelling period Soke Shioda spent as a student of Morihei Ueshiba. Yoshinkan Aikido has some 150 basic techniques which are practiced repeatedly, these enable the student to master the remaining ones, which total some 3000 overall. Like many styles of Aikido, Yoshinkan eschews competition; instead, it emphasizes self defense applications. It is one of the martial arts taught to the Tokyo police.
