Masutatsu Oyama (大山 倍達 Ōyama Masutatsu)
July 27, 1923 – April 26, 1994) who founded Kyokushin Karate,
considered the first and most influential style of full contact karate
In 1953 Oyama opened his own karate dojo, named Oyama Dojo, in Tokyo but continued to travel around Japan and the world giving martial arts demonstrations, including the fighting and killing of live bulls with his bare hands (sometimes grabbing them by the horn, and snapping the horn off). His dojo was first located outside in an empty lot but eventually moved into a ballet school in 1956. The senior instructors under him were K. Mizushima, E. Yasuda, M. ishibashi, and T. Minamimoto. Oyama’s own curriculum soon developed a reputation as a tough, intense, hard-hitting but practical style which was finally named Kyokushin, which means ‘the ultimate truth,’ in a ceremony in 1957. He also developed a reputation for being ‘rough’ with his students, as the training sessions were grueling and students injuring themselves in practice fighting (kumite) was quite common.
Along with practice fighting that distinguished Oyama’s teaching style from other karate schools, emphasis on breaking objects such as boards, tiles, or bricks to measure one’s offensive ability became Kyokushin’s trademark. Oyama believed in the practical application of karate and declared that ignoring ‘breaking practice is no more useful than a fruit tree that bears no fruit. As the reputation of the dojo grew students were attracted to come to train there from inside and outside Japan and the number of students grew. Many of the eventual senior leaders of today’s various Kyokushin based organisations began training in the style during this time.
