Glossary of Judo terminology
Blue Judo uniforms and white Judo uniforms
Although Olympic and world competitions have always been conducted in accordance with the IJF rules (International Judo Federation Rules), these rules have recently begun to be used for many competitions within Japan as well. Although the IJF rules differ from the Kodokan rules on several points, one of the most prominent differences concerns the blue uniform color. The blue uniform idea was evidently proposed by the Dutchman, Anton Geesink, winner of the gold medal at the Tokyo Olympiad, and was formally adopted by at the IJF general meeting held in October of 1997. The blue uniform made its first appearance at the Sydney Olympiad, and since then, all international competitions have paired the contestants as white uniform versus blue uniform. Although some were opposed to this idea, it was adopted in the end in order to help spectators distinguish between the combatants and identify the winner and loser more clearly. Although the All Japan Judo Federation resisted this change to the end, claiming that "the heart of Judo is white", the majority world opinion was in favor of colored uniforms. Domestic competitions within Japan still use only the white uniform.
