In 1957, Masutatsu Oyama, a Korean born Japanese, whose original name was Choi Yeong-Eui founded the Kyoukushin Kai Kan, rightfully. As per different authentic sources, it is said that Oyama started learning Martial Arts at the age of 9. His teacher was a farmer.
His second most outstanding achievement was his book titled “What is Karate?” which got the title of “Karate Bible” in the martial arts world. Its importance is as same as it was at the time of Oyama.
Oyama started his trainer career in 1953 by opening a Karate Dojo named as Oyama Dojo in Tokyo. His act of killing live bulls with bare hands got fame and Kyoukushin gained heights.
He supervised his senior instructors, named as; T. Nakamura, K. Mizushima, E. Yasuda, M. ishibashi, and T. Minamimoto, to train the newly enrolled students
In 1957, Oyama’s own syllabus developed an enough reputation as a tough, intense, hard-hitting but practical style which was finally named Kyokushinkai (Japan Karate-Do Kyokushinkai), which means ‘the ultimate truth,’. He believed in the practical application of karate and declared that ignoring ‘breaking practice is no more useful than a fruit tree that bears no fruit.
In 1964 Oyama moved the dojo into the building that would from then on serve as the Kyokushin home dojo and world headquarters. In connection with this he also formally founded the ‘International Karate Organization Kyokushin kaikan’ (commonly abbreviated to IKO or IKOK) to organise the many schools that were by then teaching the kyokushin style.
