Judo Judo has it's roots in the Japanese Martial Arts, especially in a series of Ju-Jitsu schools. In 1882 it was Dr. Jigoro Kano in Shitaya who combined different forms under the name 'Kodokan Judo'. There's a ranking system in Judo which states one's level. There are student grades (kyu) and master grades (dan). Next to a fully-featured martial art, judo has developed as a sport, even a well established Olympic sport.
