Styles

Jigoro Kano's Kodokan Judo is the only style of judo. A sub-style of Kodokan Judo that developed in Japanese inter-scholastic competition is known as Kosen judo, with the same range of techniques but greater latitude permitted for Ne-waza (ground techniques).

Teaching in France, Mikonosuke Kawaishi developed an alternative approach to instruction that continued to teach many techniques banned in modern competition. In Austria, Julius Fleck and others developed a system of throwing intended to extend Judo that they called Judo-do.
