Kanō Jigorō in the context of "Japanese martial arts"

Judo (Japanese: 柔道, Hepburn: Jūdō; lit. 'gentle way') is an unarmed modern Japanese martial art, combat sport, Olympic sport (since 1964), and 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.

The Kodokan Judo Institute (公益財団法人講道館), or Kōdōkan (講道館), is the headquarters of the worldwide judo community. The kōdōkan was founded in 1882 by Kanō Jigorō, the founder of judo, and is now an eight-story building in Tokyo.

Tenjin Shinyo-ryu (天神真楊流, Tenjin Shin'yō-ryū), meaning "Divine True Willow School", can be classified as a traditional school (koryū) of jūjutsu. It was founded by Iso Mataemon Ryūkansai Minamoto no Masatari (磯又右衛門柳関斎源正足) in the 1830s. Its syllabus comprises atemi-waza (striking techniques), nage-waza (throwing techniques), torae-waza (immobilization methods), and shime-waza (choking techniques). Once a very popular jujutsu system in Japan, among the famous students who studied the art were Kanō Jigorō and Morihei Ueshiba. Kanō founded the modern art of judo, and Ueshiba founded aikido.
