Judo as a Sport

Judo has had competitions since its inception, the first all Japan completion was a major step for Judo, and happened in 1930. The first Judo world championships were in Tokyo in 1956 although exclusively for males, the first world Championships for females also was in 1980, eventually in 1987 the first joint event for male and female competitors happened.

Judo was first included in the Summer Olympic Games at the 1964 Games in Tokyo, Japan. After not being included in 1968, judo has been an Olympic sport in each Olympiad since then. Women judoka were first awarded medals at the 1992 Summer Olympics.


Competition Format

Judoka compete in weight classes. Gold and silver medals are awarded based on a single elimination bracket. Two bronze medals are awarded in each weight class; two judoka from a repechage (In a repechage, a competitor who loses to the pool winner drops into the repechage bracket. The theory is that a worthy competitor, who is paired with another worthy competitor, should not be unduly penalized by luck of the draw, but has an opportunity to at least fight for third place.) for those who are eliminated by one of the eventual semifinalists face the two semifinal losers for the bronze medals.
