Get inside the mind of a champion. These 13 quotes from Ronda Rousey’s autobiography show what it really takes to fight—and win—at the highest level.
Masutatsu Oyama (大山 倍達), commonly known as Mas Oyama, was a Korean-born martial artist who founded Kyokushin Karate, a full-contact style renowned for its emphasis on physical toughness and discipline. Born Choi Yeong-eui (최영의) on July 27, 1923, in North Jeolla Province, Korea, he later adopted the Japanese name Masutatsu Oyama upon moving to Japan in 1938.
At the age of nine, Oyama began studying Southern Chinese Kempo, known as "Eighteen Hands," under a Chinese instructor named Yi while living on his sister's farm in Manchuria. Upon returning to Korea at age 12, he continued his martial arts training in Korean Kempo.
In 1938, Oyama moved to Japan and enrolled in Takushoku University, where he studied judo and began training in Shotokan Karate under Gichin Funakoshi, the founder of Shotokan Karate. He achieved his black belt in 1940 and later studied kosen judo.
Dissatisfied with the limitations of traditional martial arts, Oyama sought a more practical and effective system. In 1964, he founded Kyokushin Karate, emphasizing full-contact sparring, rigorous physical conditioning, and a philosophy of "maximum efficiency, minimum effort." The style gained international recognition for its intensity and discipline.
