One of the great secrets of Judo is why this book is still in print, while so many better books cannot be found anymore. This book attempts to explain Judo techniques in terms of physics. Momentum, friction, coefficients, composition of forces, and moment of force are some of the subjects you'll run into in this book. What you won't find, unfortunately, is any good Judo. I can't honestly recommend this book.

Foreword
It is a great pleasure for me to know that The Secrets of Judo is to be published under the joint authorship of Jiichi Watanabe, sixth dan, and Lindy Avakian, third dan.
Mr. Watanabe has been deeply interested in the scientific study of the various techniques of judo, especially from the viewpoint of dynamics. Mr. Avakian came to the Kodokan from the United States and earnestly studied the principles and techniques of judo here in Japan. He is now in his native country, where he has become known as an expert teacher of judo.
The Kodokan judo was born from the old jujitsu of Japan. Now, having been reorganized from the viewpoint of physical education, it has become an excellent sport, much favored in many nations of the world.
I believe that this book of the two judomen will be welcomed as a good guide for foreign students.
