Competition format

Judoka compete in weight classes. Each country may qualify a maximum of one athlete per weight class.^[3] Gold and silver medals are awarded based on a single elimination bracket. Two bronze medals are awarded in each weight class; quarter-finalists losers fight against each other in the same half of bracket. Losers finish in seventh place, winners advance to the bronze medal contest against losing semifinalist of the opposite half of the bracket. Winners of these contests receive bronze medal and losers finish in fifth place.

There have been between 4 and 8 Olympic weight classes over the years (currently 7), and the definition of each class has changed several times, as shown in the following table.
