Sosai
Mas Oyama 10TH Dan
Founder of Kyokushinkai
Masutatsu Oyama was born in South Korea in 1923, and completed middle school in Seoul. When he was 12 years old he moved to Japan to live. Sosai Oyama had mastered the Eighteen Techniques of Chinese Kempo while he was still in his homeland. When he came to Japan, he became a student of Gichin Funakoshi, the man who introduced karate into Japan, and soon achieved the status of a second-grade (Dan) karate master.
He interrupted his college education when he was drafted into the military in 1943, but he continued his karate studies with Sodeiju, then karate instructor at the Goju school. By the time the war was over, he had become a fourth-grade karate master. In 1947, after he had won the All-Japan Karate Tournament, he resolved to live his life in the way of karate and determined to follow the doctrines of its way. After 1948, for a full three years, he secluded himself from human society, devoting himself completely to a life according to the precept of Zen. He lived in the mountains and subjected himself to the disciplines of the martial arts both night and day. Through such rigorous training as seated meditation under waterfalls, struggles with wild animals, and smashing trees and stones with his bare hands, Oyama refined not only his doctrine of karate, but also his own mind and body.
The renown of Oyama karate flashed abroad with such speed that a training hall soon became necessary for the many students wanting to be trained in the Oyama way. In Japan, the first Oyama training hall, the Kyokushin Kaikan, opened in 1955, and in 1964 a new five-story hall.
In 1994 Sosai Oyama passed away and left behind millions of kyokushin karateka spread all over the world . Today we have many major world organizations , each claiming to be the real continuation of Sosai Oyama's Kyokushin Karate.
