The 100-man kumite is an extreme test of physical and mental endurance in Kyokushin karate. Kumite is a form of sparring, one of the three main sections of karate training, and involves simulated combat against an opponent. The 100-man kumite consists of 100 rounds of kumite, each between one-and-a-half and two minutes in length. Normally, the karate practitioner undergoing the test will have to face similarly or higher-ranked opponents, and may face the same opponent more than once in the course of the test. Each opponent faced will be fresh and not fatigued or injured. Each of the rounds are done under test conditions, where either of the fighters are allowed to deliver knock out blows.
