 Judo is a Japanese martial art that was established in 1882 by Jaguro Kano. It is derived from several traditional jujitsu styles such as Tengen Shiryu and Kitoryu. Kano had learned extensive free sparring or randori early in his training and he began to develop a Jujitsu style that focused less on strikes and weapons and instead placed an emphasis on throwing techniques, joint manipulations and takedowns. He wanted to make his style distinct from other jujitsu systems so he named his art Judo which means gentle way or gentle method. He also founded the Kodokon, the governing organization that oversaw the teaching of Judo. Judo became one of the widest spreading arts in Japan and stands as one of the most popular combat sports in the world. In addition to establishing such a prolific art, Kano also created the colored belt system, the Kyudan rankings and implemented the use of dogi as a traditional uniform. Talk about being on the roll.
