Kanō Jigorō (嘉納 治五郎 28 October 1860 – 4 May 1938) was the founder of judo. Judo was the first Japanese martial art to gain widespread international recognition and the first to become an official Olympic sport. Pedagogical innovations attributed to Kanō include the use of black and white belts and the introduction of dan ranking to show the relative ranking between members of a martial art style.
