In randori, one must search out the opponent's weaknesses and be ready to attack with all the resources at his disposal the moment the opportunity presents itself, without violating the rules of judo.

Judo is the way to the most effective use of both physical and spiritual strength.

Judo is a study of techniques with which you may kill if you wish to kill, injure if you wish to injure, subdue if you wish to subdue, and, when attacked, defend yourself

Carefully observe oneself and one's situation, carefully observe others, and carefully observe one's environment. Consider fully, act decisively.

There are people who are excitable by nature and allow themselves to become angry for the most trivial of reasons. Judo can help such people learn to control themselves. Through training, they quickly realize that anger is a waste of energy, that it has only negative effects on the self and others.

The purpose of the study of judo is to perfect yourself and to contribute to society.

Paradoxically, the man who has failed and one who is at the peak of success are in exactly the same position. Each must decide what he will do next, choose the course that will lead him to the future.
