Masutatsu Oyama – Sosai’s History
An early start
Masutatsu (Mas) Oyama was born Yong I-Choi on the 27th of July, 1923, in a village not far from Gunsan in Southern Korea. At a relatively young age he was sent to Manchuria, in Southern China, to live on his sister’s farm. At the age of nine, he started studying the Southern Chinese form of Kempo called Eighteen hands from a Mr. Yi who was at the time working on the farm. When Oyama returned to Korea at the the age of 12, he continued his training in Korean Kempo.
In 1938, at the age of 15, he travelled to Japan to train as an aviator, to be like his hero of the time, Korea’s first fighter pilot. Survival on his own at that age proved to be more difficult than he thought, especially as a Korean in Japan, and the aviator training fell by the wayside.
He did however continue martial arts training, by participating in judo and boxing, and one day he noticed some students training in Okinawan Karate. This interested him very much and he went to train at the dojo of Gichin Funakoshi at Takushoku University, where he learned what is today known as CyberDojo home pages.
His training progress was such that by the age of seventeen he was already a 2nd dan, and by the time he entered the Japanese Imperial Army at 20, he was a fourth dan. At this point he also took a serious interest in judo, and his progress there was no less amazing. By the time he had quit training in Judo.
