Judo

Judo is generally categorized as a modern Japanese martial art, which has since evolved into a combat  and Olympic sport.  With its origins coming from jujitsu, judo's most prominent feature is its competitive element, where the objective is to either throw or take down an opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke.  Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in pre-arranged forms and are not allowed in judo competition or free practice.
