In Randori we teach the pupil to act on the fundamental principles of Judo, no matter how physically inferior his opponent may seem to him, and even if by sheer strength he can easily overcome him; because if he acts contrary to principle his opponent will never be convinced of defeat, no matter what brute strength he may have used.

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

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

Judo helps us to understand that worry is a waste of energy.

If there is effort, there is always accomplishment.

Before and after practicing Judo or engaging in a match, opponents bow to each other. Bowing is an expression of gratitude and respect. In effect, you are thanking your opponent for giving you the opportunity to improve your technique.

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