Olympic judo rules

The objective of judo is to subdue your opponent without striking them, using a variety of throws, pins or joint locks.

Competitors face each other on a 10x10 padded mat and begin by making grabs at each other in an attempt to unbalance their opponent or achieve a firm hold with which to throw.

The sport allows 68 different throwing techniques, known as nagewaza, and 32 grappling techniques, called katamewaza.

Competitors are awarded a half-point called a waza-ari for successful moves, but a perfectly executed throw will receive ippon, a full point, which automatically wins the match.

Ippon can also be awarded for holds that keep the opponent pinned for 20 seconds, or choke holds that force the opponent to submit.

Since 2016, judo rules have been revised to make men's and women's matches of equal length at four minutes, and the judging time for waza-ari was reduced from 15 seconds to ten, in order to make matches faster and more aggressive.

Competitors who achieve ippon outright or through two waza-ari will win the match, and tied scores are resolved by a "golden score" system which awards the match to the next scoring player.

The new mixed team event will use competitors drawn from the individual competition, with each team composed of an under 73kg, under 90kg and over 90kg male competitor, and an under 57kg, under 70kg and over 70kg female competitor.
