A brilliant young educator, Jigoro Kano learned  jujutsu for self defense in the often violently abusive Japanese university dorms of the late 1800s.

Kano mastered three styles of jujutsu, then analyzed each technique by reason and physics to improve it or reject it.

Techniques included in judo must be simultaneously effective for self defense, physical education and mental development.

Each technique is both an athletic performance and the execution of a high level physics equation.

This makes judo an excellent tool for human development.

It allows full-power application of techniques in training because all the dangerous and unreasonable techniques were removed and the existing techniques have all been optimized to the laws of physics.

Kano taught “maximum efficient use of effort” and “prosper together with the opponent.”

The depth of his wisdom is reflected in the abilities of some of his great students, such as Kyuzo Mifune and Sampo Toku.

It was Jigoro Kano who recognized the young Minoru Mochizuki as an emerging leader in Japanese martial arts and culture.




Minoru Mochizuki was born in Shizuoka City, Japan, in 1907.

Called Sunpu in samurai days, Shizuoka was the shogun’s summer home and an important seat of power in Japan.

Until the end of the samurai era, in 1868, Mochizuki’s grandfather was a samurai in the shogun’s Sunpu castle.

This former samurai was Minoru Mochizuki’s first teacher in judo/jujutsu and sword.

Mochizuki went on to train under Sampo Toku and was uchi deshi to Kyuzo Mifune before officially joining the kodokan in 1926.

With such a background, Mochizuki caught the attention of Jigoro Kano, who enrolled him in a Classical Budo Research Group to study various Japanese martial arts and teach them at kodokan. It was through this group that Mochizuki trained in karate, classical swordsmanship and aiki-jujutsu.

Of all his many teachers, Minoru Mochizuki maintained a lifelong gratitude and respect for both Jigoro Kano and Morihei Ueshiba but it was Kano’s emphasis on rational thinking and development of ji ta kyo ei (prosper together with the opponent) that Mochizuki most wanted to propagate.
