In this book, G. Koizumi, internationally known authority and the "father" of Judo in the West, draws upon his lifelong experience to present the principles and technical fundamentals of this exciting sport. The various schools of Ju Jutsu including all their techniques, traditional methods and secrets of the art, are explained. Each position and throw is illustrated with a clear, easy-to-follow photograph. The real value of Judo lies in the effects which the training produces on the state of the body and mind. The emphasis on both technique and philosophic rationale is what distinguishes My Study of Judo from other books on the subject.
