The Yoshinkan 'House for Cultivating the Spirit' was founded after World War Two. This style of aikido is occasionally called the hard style because the training methods are a product of the gruelling period Soke Shioda spent as a student of 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. Yoshinkan Aikido is not a sport. Aikido is the development and strengthening of the body and mind, and the practical side of Aikido must never be forgotten. However, Aikido is for all, irrespective of age, sex, race or culture.
