Mas Oyama and the origins of Kyokushin
Sosai Masutatsu Oyama, known as Mas Oyama, developed Kyokushin Karate in Japan. He opened Oyama Dojo in Tokyo in 1954 and founded the International Karate Organization Kyokushinkaikan in 1964.
Oyama helped establish full-contact knockdown competition through the first All Japan Open in 1969 and the first World Open in 1975. Kyokushin, often translated as “ultimate truth,” combines technical practice with discipline, perseverance and respect.
