"In our society today, when we teach the righteous way of life based upon the Theory of judo which embodies the principles of continuous improvement of society, then this righteous life provides a basis of definite proof of this principle and unifies the peoples' way of thinking. Various religious and learned points of view are then made abundantly clear."

“Walk a single path, becoming neither cocky with victory nor broken with defeat, without forgetting caution when all is quiet or becoming frightened when danger threatens.”

“Judo is the way to the most effective use of both physical and spiritual strength. By training you in attacks and defenses it refines your body and your soul and helps you make the spiritual essence of Judo a part of your very being. In this way you are able to perfect yourself and contribute something of value to the world. This is the final goal of Judo discipline.”

“Generally speaking, if we look at sports we find that their strong point is that because they are competitive they are interesting, and young people are likely to be attracted to them. No matter how valuable the method of physical education, if it is not put into practice, it will serve no purpose — therein lies the advantage of sports. But, in this regard there are matters to which we must also give a great deal of consideration. First, so-called sports were not created for the purpose of physical education; one competes for another purpose, namely, to win. Accordingly, the muscles are not necessarily developed in a balanced way, and in some cases the body is pushed too far or even injured. For that reason, while there is no doubt that sports are a good thing, serious consideration must be given to the selection of the sport and the training method. Sports must not be undertaken carelessly, over-zealously, or without restraint. However, it is safe to say that competitive sports are a form of physical education that should be promoted with this advice in mind. The reason I have worked to popularize sports for more than twenty years and that I have strived to bring the Olympic Games to Japan is entirely because I recognize these merits. However, in times like these, when many people are enthusiastic about sports, I would like to remind them of the adverse effects of sports as well. I also urge them to keep in mind the goals of physical education—to develop a sound body that is useful to you in your daily life — and be sure to consider whether or not the method of training is in keeping with the concept of seiryoku zenyo.”

“Another tenet of randori is to apply just the right amount of force — never too much, never too little. All of us know of people who have failed to accomplish what they set out to do because of not properly gauging the amount of effort required. At one extreme, they fall short of the mark; at the other, they do not know when to stop.”

“Another point is the meaning of professionalism. With Judo, we have no professionals in the same sense as other sports. No one is allowed to take part in public entertainment for personal gain. Teachers certainly receive remuneration for their services, but that is in no way degrading. The professional is held in high regard like the officers of a religious organization or a professor in the educational world. Judo itself is held by us all in a position at the high altar. To reconcile this point of view with the Western idea is difficult. Success or a satisfactory result of joining the Olympic Games would much depend on the degree of understanding of Judo by the other participating countries.”

“Judo should be free as art and science from any external influences, political, national, racial, and financial or any other organized interest. And all things connected with it should be directed to its ultimate object, the "Benefit of Humanity". Human sacrifice is a matter of ancient history.”
