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

Apply just the right amount of force — never too much, never too little.

In randori we learn employ the principle of maximum efficiency even when we could easily overpower an opponent.

Nothing under the sun is greater than education. By educating one person and sending him into the society of his generation, we make a contribution extending a hundred generations to come.

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.

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.
