Kata (martial arts) in the context of "Judo"

Karate was an event held in the 2020 Summer Olympics in Tokyo, Japan. It was the debut appearance of karate at the Summer Olympics. Karate was one of four optional sports added to the Olympic program specifically for 2020, rather than as a permanent sport. After it was announced it would not be included in 2024, in August 2022 it was announced that karate had made the shortlist for inclusion in the 2028 Games, although it was ultimately not selected.

The karate competitions at the 2020 Olympics featured eight events. Two karate disciplines were featured: kumite was the sparring discipline and had three weight classes each for men and women; kata was the solo form discipline, and had one event each for men and women. Competitors chose the kata to demonstrate from 102 kata that were recognized by the World Karate Federation. Competitors were not allowed to demonstrate the same kata twice during the tournament. Each event had 10 competitors.

Kumite (Japanese: 組手, literally "grappling hands") is one of the three main sections of karate training, along with kata and kihon. Kumite is the part of karate in which a person trains against an adversary.

Kumite can be used to develop a particular technique or a skill (e.g. effectively judging and adjusting one's distance from one's opponent) or it can be done in competition.

Judo (Japanese: 柔道, Hepburn: Jūdō; lit. 'gentle way') is an unarmed modern Japanese martial art, combat sport, Olympic sport (since 1964), Paralympic sport (since 1988) and Commonwealth Games sport (since 1990). Judo is the most prominent form of jacket wrestling competed internationally. Judo was created in 1882 by Kanō Jigorō (嘉納 治五郎) as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on "randori" (乱取り, lit. 'free sparring') instead of kata (形, kata; pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, Keishicho Bujutsu Taikai), resulting in its adoption as the department's primary martial art. A judo practitioner is called a "judoka" (柔道家, jūdōka), and the judo uniform is called "judogi" (柔道着, jūdōgi; lit. 'judo attire').

The objective of competitive judo is to throw an opponent forcefully onto their backs, immobilize them with a pin, or force an opponent to submit with a joint lock or a choke. While strikes and use of weapons are included in some pre-arranged forms (kata), they are not frequently trained and are illegal in judo competition or free practice. Judo's international governing body is the International Judo Federation, and competitors compete in the international IJF professional circuit.
