Peter Seisenbacher is one of the great judo champions. George Kerr was his coach and a judoka (judo student) trained in the old, traditional style of judo. Both present their ideas and views about judo in this well written text. Judo students will gain a deeper understanding of the philosophy and principles of judo from two different perspectives. The book begins with George Kerr telling about judo and his training. Peter Seisenbacher then writes about his ideas and understanding of judo. The contrasting views provide the reader with insight and a better understanding of judo philosophy. In addition, Peter Seisenbacher presents invaluable commentary on the techniques and tactics that made him so successful in sport judo. This book will be an invaluable addition to any judo students library.
Of the Judo books I've read, all but this one describe the history, principles, and some of the techniques. This is the only book that addresses the sport of Judo. It does focus on the SPORT aspect and as long as you're looking for that (and not the samurai aspect) this is a great book. I think it's the only one to address the competitive, sport version of Judo.
