Korean-Japanese full-contact karate master, the founder of Kyokushin (1922-1994)
He turned karate into something you could test by breaking bones — your opponent's or your own. Mas Oyama built Kyokushin around full contact, no pulled punches, and made it the template every hard style since has measured itself against.
Born Choi Yeong-eui on 27 July 1923, he carried a Korean name into a Japanese art and remade both. He founded Kyokushin Karate, stripping away the ceremonial distance and insisting students hit for real. It became the first full-contact style that mattered, the one every other hard school had to reckon with. He died 26 April 1994, but the bruises are still standard issue.
