Ippon

is the highest score a fighter can achieve in a Japanese martial arts ippon-wazari contest, usually kendo, judo, karate or jujitsu.

==In judo== In judo, an ippon may be scored for a throw, a pin, a choke or a jointlock. For throws, the four granting criteria are speed, force, landing on the back and skilful control until the end of the landing. For pinning techniques, the pin must be held continuously for 20 seconds. For chokes and locks, it is scored when the opponent gives up or is incapacitated.
