The Judo competition at the 1972 Summer Olympics was the return of the sport following its absence at the 1968 Summer Olympics in Mexico City. Medals were awarded in 6 classes, and competition was restricted to men only.
Judo competition takes place on a mat that ranges in size from 14 to 16 m (45.9 to 52.5 ft) square and is divided into two zones.
A judo match is won when one contestant scores an ippon, which is awarded for several reasons: a clean, forceful throw; holding an opponent down for 30 seconds; or applying a successful choke hold or elbow lock.
Judo was not an event at the 1968 Summer Games in Mexico City, but it returned to the Olympics at the 1972Summer Games in Munich, West Germany.
