Judo developed from jiu-jitsu, an art of self-defense that was popular during the Tokugawa period.
Judo has three basic strategies–attacking the opponent’s vital points, throwing the opponent, and grappling. One referee and two assistants preside at a judo match.
Judo, (literally the “way of gentleness”), is the gentle art of grappling and throwing and was conceived and developed by Japanese master of swordsmanship and hand-to-hand combat, Jigoro Kano. The techniques used in Judo are taken from Jiu-Jitsu and are designed to use mental and physical energy efficiently. Judo is therefore ideal for developing fitness, stamina and mental discipline, and is well suited to both juniors and adults regardless of their age or ability. Techniques include rolls, grappling, throwing, holds and free practice.
The winner is the first man to throw his opponent to the floor, to lift his opponent over his shoulders, to pin him down until he gives up, or to pin him for at least 30 seconds. If neither contestant accomplishes any of these goals, the match is awarded to the more aggressive of the two. Colored belts are worn to indicate degrees of mastery in judo.
