In 1952, Oyama was invited by a famous a “Ni Sei” a second generation Japanese / American wrestler named “Great Togo” to the United States with another fellow Japanese judo fighter Kokichi Endo. The three formed a unit and adopted their wrestling alias - “The Togo's Brothers”. As Oyama became “Mas Togo", he toured with other “Togo Brothers” and participated in the wrestling matches around the Midwest and South Atlantic to show Americans the power of Karate. He showed his strength by breaking wooden boards, crushing stones, and sometimes inviting challengers such as wrestlers and huge guys from spectators. People marveled at his lightning quick moves (some people named him "Thunderbolt Togo"), praised them as magical, and eventually called him the “God Hand” or “Hand of God.”
In 1954, Oyama challenged himself to break the horns of a Japanese bull with his bare hands, each bulls weighed over 900 lbs and filmed for a documentary at the beach in Tateyama, Chiba Prefecture. Oyama had successfully broke the horns of 47 bulls in the previous six months of the training period, the bull that was chosen for the film was a size of another level. It was his first time to fight a bull of that size, he was very nervous. After a fierce battle, he broke the horns with a shuto (knife-hand strike) blow and finally ripped them off. Although he may be criticized today, he was undoubtedly the result of his dedicated training of “Oyama Karate”.
