Lots of quite interesting ideas packed into a small book. Very rare throws such as Dai-Sharin, Suso-Seoi, and various kansetsuwaza that are illegal in competition. (How many of you have ever learned Sekizui-Waza?) Plenty of B/W photos illustrating the text are included. This book is quite interesting reading from the founder of the Budokwai.

During recent years steps have been taken to organize and encourage sports and games on a national basis. Such a scheme may have been inspired by the Utopian concept of a welfare state, or may be due to the recognition that for the success of national efforts in war or peace, much depends on the physical fitness of the citizens. Whatever the root of the inspiration may have been on the trend of this physical awareness, Judo training as sport has attracted popular imagination, and in rapid succession Judo clubs have been brought into being all over the country, and the movement is now organized nationally and internationally, and has established itself prominently in the field of sports. Following on the trail of such development, a number of books on Judo have been published, with varying merits. Contribution of my own effort to this collection has been suggested more than once, but I have been reluctant to acquiesce, being conscious of the fact that the subtle touches and delicate technical variants on which the efficiency of this art depends cannot possibly be committed to paper. From the instructional point of view the value of books on Judo is limited to that of a finger pointing to an object.

However earnest approaches made by my old friend, E.J. Harrison (4th Dan) who has done much in introducing Judo to English-speaking countries by his personal example and voluminous literary activities, together with the Chairman of his publishers, persuaded me to take a view (perhaps influenced by the passing of the years) that the experiences and knowledge I have gained through a life-long association with the study of Judo may be of some service to the students and the cause of the Judo movement, even though my effort to describe them would also end in the nature of the pointing finger. Thus I was put on the spot to labor for the birth of this book, instead of enjoying the privileges due to the aged and retired. For the reasons I have stated, this book is not in the form of a textbook, but is in the nature of a discourse arranged in an order of successive stages. It is not a series of descriptions of specific techniques. The techniques are grouped according to their theoretical basis and studied under the light of the fundamental principle - maximum efficiency and minimum effort. The effects of the training on the physical, mental and emotional life I have expounded in this book are my personal experiences, not hypothetical assumptions.

However, I must say that the extent of the study I have made is far from exhaustive and my personal capacity has not been equal to the magnitude of the subject. I shall be content if my efforts are, in some way, found to be a serviceable contribution to the cause of the Judo movement. I should like to take this opportunity to express my sincere gratitude and indebtedness to the founder, the late Professor Jigoro Kano, for his immortal teaching, and pay homage to the memory of personal association, to which I was privileged; also my appreciation to those who have granted to me the benefit of their knowledge and wisdom, not excluding those who have unwittingly provided problematic material for my study with their questions and mistakes, lastly but not least to those who have assisted me in producing the illustrations, including W. Stepto, 3rd Dan, R. Bowen, 3rd Dan and Hilton Green with his camera, and to Miss K. White-Cooper, the first lady member of the Budokwai, for her help in editing the text.

G. Koizumi.



I was born on 8th July, 1885, in the province of Ibaraki, about twenty miles north of Tokyo. Japan was then going through the process of readjustment needed to adapt herself to the newly created political order and international relationships.

When I was twelve years of age I joined a Kenjutsu (Double-handed swordmanship) class, and enjoyed the training under the master of the school which I attended, for three years. Moving to Tokyo, and under the stress of the usual schoolboy feuds, I took up Tenshin-Shinyo-Ryu Ju Jutso under NOBUSHIGE TAGO, who was quite an impressive figure with a long grey beard, although the actual training was mostly left to his young assistant, N. TAKAGAKI. He was a good teacher, kind and gentle, but in RANDORI one day, soon after I had started training, he gave me some terrific kicks, wild pushes and pulls. Then abruptly stopping, he quietly asked me, "Do you know that is what you are doing to me?" Since then, how often have I been reminded of this episode by the zeal of eager beginners! At this TAGO Dojo much time was devoted to the practice of KATA, for which the participants wore black HAKAMA (divided skirt), a band of white cloth across the forehead with the ends knotted at the back of the head and, sometimes, a wooden sword and daggers.

In 1904, in Fusan, Korea, I attended the Kenjutsu and Ju JUTSU school conducted by an ex-samurai of the Owari clan, Sensei NOBUKATSU YAMADA and learned the techniques of SHIN-SHIN-RYU, JU JUTSU and KATSU. During a four months' stay in Singapore from November 1905 to February 1906, I helped Sensei T. Akishima in conduct of his Ju Jutsu school and was taught the 144 techniques of AKISHIMA-RYU and KATSU. His method of instruction was only in the form of KATA. The participators stood at each end of the Dojo and after an exchange of Kiai, they met in the center for action. The technique consisted of throws, locks and blows, many of which were of doubtful practical value. However, I owe Sensei Akishima much for his instruction in the technical essentials which were taught in the olden days only to those who were approved by the teacher. Arriving in England in May 1906, I stayed for twelve months, instructing at the KARA ASHIKAGA school of Ju Jutsu, Liverpool, the Piccadilly school of Ju Jutsu, the Polytechnic, the Royal Naval Volunteer Reserve, etc. At this time, Ju Jutsu was much in vogue, with YUKIO TANI, TARO MIYAKE, RAKU UYENISHI, AKITARO OHNO touring the music halls.

After a three years' sojourn in the U.S.A. studying electrical engineering, I returned to London in May 1910 and settled down, making it my permanent home. In January 1918, I opened the Badokwai Dojo for the practice of Ju Jutsu, Kenjutsu and other martial arts of Japan. This club was conducted on the lines of an Amateur Sports Club. The Budokwai since has served as the pioneer in developing and establishing the Judo movement on a national and international basis.

In 1920 on the occasion of the late Professor Jigoro Kano's visit with Mr. Hikoichi Aida, who was to be the first Judo instructor to the Budokwai, Mr. Tani and I joined the Kodokan and were graded to 2nd Dan. I was influenced to take this step by the fact that the Kodokan was founded as an educational institution, free from financial interests, with the object of facilitating the study and practice of Judo as a means of physical, mental and ethical training, elevating Judo as a scientific and ever progressive subject on the principle of maximum efficiency and minimum effort.

I was graded to 4th Dan in 1932, to 6th Dan in 1948 and to 7th Dan in 1951, for the number of throws I have taken as a subject experimental. Now, I am privileged to repose at the end of the Dojo and indulge in KUCHI-WAZA - mouth technique.
