Judo is a modern Japanese martial art founded by Jigoro Kano. Kano established the Kodokan school of martial arts in 1882, incorporating several styles of traditional Japanese martial arts, such as jujitsu and yawara. Judo techniques are divided into 3 major categories: throwing, grappling, and striking. Karate-like striking techniques are considered dangerous and thus are not permitted in tournaments. After World War II judo gained popularity internationally, and is practiced as a competitive sport all over the world. 意訳:1882年嘉納治五郎が講道館を創立し,柔術・やわらなど古武道各流派を統合して作った格闘技.投げ技・固め技・当て身技の三つからなるが,当て身技は危険を伴うため試合では禁止されている.第2次世界大戦後には世界的に広まった
