Kyokushin Karate was founded by Masutatsu Oyama who studied various martial arts from the age of 9. He learned the Chinese Kempo form "Eighteen Hands", judo, boxing, Okinawan Karate and Goju Ryu karate. He was famous for his battles with 52 bulls in 1950, where he instantly killed 3 and chopped off the horns 49 with knife-hand blows. A year later, he opened his first dojo in Mejiro, Tokyo and was known for severe training. He also learned from his students who were members of other styles, wherein he infused what he felt were the best techniques from those martial arts with his training. However, at this time, his art had no name yet and his school was known as the "School of Oyama". It was only in 1964 did Masuatatsu Oyama adopt the name "Kyokushin" or "The Ultimate Truth".
Kyokushin's Hyaku Nin Kumite
Kyokushin is known for its unique ultimate test known as the Hyaku Nin Kumite or the one Hundred-Man Kumite only for practitioners of the art. The main goal is for a practitioner to fight 100 opponents in full-contact knockdown fighting for about two minutes. If one surrenders, loses consciousness or be knocked down for more the five seconds then one would automatically fail the test regardless of how far in the test you've gone. Should the bout come into decision, winning the fight depends on ippon or full points so techniques such as blocking or evading to keep on your feet won't necessarily be a great strategy. In order to prove that this can be accomplished, Masutatsu Oyama, founder of Kyokushin, fought 100 opponents a day for three consecutive days and would have continued for a fourth day but there were no more opponents left for him to fight. There have been only 13 other people in the world who have successfully completed the Hyaku Nin Kumite.
When the Hyaku Nin Kumite exam started, the hundred fights were completed in two days with 50 fights each day. Masutatsu Oyama then decided that it should be completed in one day. On December 1, 1972, Shin Howard Collins, a 7th Dan from Britain, was able to complete 100 fights in less than four hours in one day. Since then, all of the others who were able to complete the test have also done so in less than four hours.
