The judo history makes a fascinating study and can provide valuable insight into judo techniques. Soon after the end of the Tokugawa period in Japan, the Restoration period was in progress, and the old forms of hand-to-hand combat were replaced by weapons of steel.

About this time, an eighteen-year-old student, soon to become famous among Japanese educators, began his practice of jujitsu under the instruction of Professor Hachinosuke Fukuda, the eminent master of the Tenj in Shinyo-ryu school. The student, who was to become the founder of judo, was Jigoro Kano. After the death of Professor Fukuda, Dr. Kano trained under the new master of that school, Professor Masatomo Iso. Death soon took Professor Iso, however, and Dr. Kano transferred to the Kito-ryu school to study under Professor Tsunetoshi Iikubo.

Dr. Kano began to study jujitsu because of his respect for the prowess of his masters, but he soon began to thirst for a mental knowledge that was lacking in their teachings. He began to look for the secrets behind the superior expert control that the professors had mastered. He theorized that there would be greater value in combining the various schools and their techniques into one standard system: one that could be adopted as a physical education program for schools and would at the same time embody mental culture as well as physical skill.

In addition, jujitsu could be practiced as a competitive sport if the more dangerous techniques were omitted. This mastery of mental culture could thus produce a pattern of subconscious behavior that would be useful in achieving “mutual welfare and benefit.” He wanted a system that would be rational and logical and would develop the potential of the student’s real personality. The ‘do’ of the word judo symbolizes this philosophy.

In 1882 Dr. Kano formed his system and called it “judo,” the word which has now superseded the term “jujitsu.” The final step in the history of judo came when he founded the Kodo-kan in Tokyo, the institution that was to become the mecca of judo. The name Kodokan is made up of three words: ko, meaning “to preach,” do, meaning “way,” and kan, meaning “hall.”

Dr. Kano explained the new art of judo by pointing out that “gentleness means giving way until the right moment arrives”; that is, not to oppose the brute force of your opponent and thus to be defeated, but to utilize this force to your own advantage.

Suppose that your opponent has a total force of ten units, while yours is equal to three. If he pushes toward you with a force of seven units and your force equals only three, it is futile for you to try to oppose his force, for it will overcome you. But if you give way and harmonize your force of three units with his attacking force of seven, you automatically acquire a force of ten units.

Now you can defeat him because you can overcome his force of seven units with yours of ten. It can thus be appreciated that judo is a highly valuable science as well as an art, and this can be applied to judo technique.
