judo

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 Samurai throws and self-defense competed internationally. Judo was created in 1882 by Kanō Jigorō () 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" (, lit. 'free sparring') instead of 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 , and the judo uniform is called .

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.
