 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.
