Mas Oyama gained renown fame throughout Japan and then world wide for his championship win in the Japanese Martial Arts Championships, successful completion of the 100 Man Kumite three times in a row in three days and his public exploits such as wrestling a bull to the ground and then chopping off its horn with his bare hands. Through consistent exploits of human achievement, Mas Oyama demonstrated the power of the human body that anyone could achieve through dedication and rigorous training. Through founding his full contact style of Kyokushin Karate, dojos soon spread around the world.
