Shigeru Ōyama

Shigeru Oyama was a karate practitioner and instructor who operated a dojo in New York for half a century. He taught Kyokushin karate for many years before forming his own organization World Oyama Karate in 1985. He was hand-picked by Mas Oyama, karate master and founder of Kyokushin karate, to spread his contact style of karate in the United States and was sent to New York City to teach in 1966. S. Oyama is acknowledged as one of the first Kyokushin stylists to successfully complete the 100-man kumite. Oyama has taught many students, including Willie Williams and Frank Clark. Of the many Japanese Kyokushin karateka who sought training under S. Oyama, Joko Ninomiya chose to stay in America to also teach, and he became branch chief for Kyokushin in Denver, CO in 1976.
