yudo

Yudo, also known as judo, is a modern Japanese martial art, combat and Olympic sport created in 1882 by Japanese polymath and educator Jigoro Kano. Kano created judo based on his studies of various jujutsu schools, particularly Tenjin Shinyo-ryu and Kito-ryu. The fundamental principle of judo is "maximum efficiency, minimum effort" (Seiryoku Zenyo) and "mutual welfare and benefit" (Jita Kyoei).

Judo emphasizes throws, grappling, and pins. Striking techniques such as punches and kicks are generally not permitted in judo competition, though they are part of the kata (prearranged forms). The goal of a judoka (a practitioner of judo) is to throw their opponent to the mat, control them with a pin, or force them to submit through joint locks or chokeholds. Judo was the first Japanese martial art to become an Olympic sport, debuting at the 1964 Summer Olympics in Tokyo. It is practiced worldwide by millions of people, with a strong emphasis on physical fitness, discipline, and respect. The governing body for judo is the International Judo Federation (IJF).
