The 100-Man Kumite (Japanese: hyakunin 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 an opponent a few times in the course of the test (depending on the number of opponents available to participate).
The challenge was devised by Masutatsu Oyama, the founder of Kyokushin and the first person to complete the test. The second man to complete the test was Steve Arneil in 1965. In July 2004, a woman named Naomi Ali completed the 100-man kumite
