Perhaps the most unique challenge in all of Karate is Kyokushin Karate’s Hyakunin Kumite or 100-man Kumite Challenge. Devised by Kyokushin Karate founder, Mas Oyama, the challenge is the ultimate mental and physical challenge, designed to test one’s spirit. Kenji Yamaki described the challenge as a transformative experience. Howard Collins said it was the hardest three hours of his life.
The challenge involves having to fight 100 opponents, one after another. Fights are full-contact and typically last around two minutes. The only protection fighters are allowed are a mouthguard in the groin protector. If knocked down, a fighter must get up within five seconds, or fail the challenge. Fighters must win at least 50% of the fights to pass the challenge. Typically, opponents are the same grade or higher, although sometimes lower grades may be used. Fighters may have to fight the same opponent more than once, depending on the number of opponents available.
Mas Oyama was the first person to complete the challenge. He would not ask students to undergo something he could not do. He did the challenge three times, on three consecutive days. He wanted to do it on the fourth day. However, there were no opponents left. Originally Oyama wanted the challenge to be a requirement for 4th or 5th Dan grading. However, this idea was abandoned as not every fighter could handle the gruelling challenge.
The first man to complete the challenge after Oyama was South African, Steve Arneil. Others had attempted the challenge but failed. On 21 May 1965, Arneil took the challenge. He completed it in 2 hours 45 minutes. He knocked out his first opponent in around 15 seconds. He would go on to knock out around 30 of his opponents. He did lose some flights, but importantly he survived. He became the first non-Japanese to complete the challenge. Tadashi Nakamura became the second man to complete the challenge in 1965. He completed his challenge on 15 October.
Shigeru Oyama, no relation to the Kyokushin founder, took the challenge on 17 September 1966. A renowned fighter, he was undefeated in Japan. During his challenge, he had 122 fights. He is quoted as saying:
100 kumite is the hardest thing I ever did in my life. It is probably the hardest thing anyone can do in the Karate world. You don’t beat the 65th man with your body. That’s all gone by then. You beat him with your spirit.Shigeru Oyama
1967 saw two men complete the challenge. Dutchman Loek Hollander took the challenge on 5 August. According to John Jarvis who witnessed the challenge, the temperature in the dojo was 110°F (approximately 45°C). Hollander spent the next two weeks recovering from numerous minor injuries. New Zealander, Jarvis took the challenge on 10 November. He had been in Japan training with Mas Oyama when he was asked to take the challenge. He had previously spent two years in the UK training Steve Arneil.
On 1 December 1972 Welshman Howard Collins became the first person to compulsory complete the challenge in a single day. He had arrived in Japan in 1971. He eventually became an uchi-deshi (live-in student), at the main Kyokushin dojo in Tokyo. He had seen other students attempt the challenge, so knew what to expect. He completed the challenge in 3 hours 30 minutes. He said:
I thought they were going to kill me, but everything went. These are the three hardest hours of my life that I will remember forever.Howard Collins

A tough endeavour, the 100–man challenge has seen many failures. As previously mentioned, Keiji Sanpei, a former head of the IKO–2, failed on his first attempt at the challenge. Makoto Nakamura, a former two-time World Champion also failed in his attempt.
Over the years there have been a number of variations to the 100–man Kumite format. This includes 20–man, 40–man, and 50–man, challenges.
There is no doubt that the 100-man challenge will be attempted again. The Hyakunin Kumite Challenge still remains one of the ultimate tests of a karateka’s mental and physical strength. It is an expression of Budo in its purest form.
