I.K.O.N.
ABOUT I.K.O.N.
International Karate Organization Nakamura (I.K.O.N.) is a worldwide Karate organization with a deep-rooted tradition of excellence. After the untimely death of Sosai Mas Oyama, the original Kyokushin organization split into many groups that created their own Kyokushin organizations. Subsequently, under their leadership, a wide range of technical components, including kumite rules, have been changed.
​
Our logic is simple; Bring back Sosai's Kyokushin. We strive to bring back the techniques, philosophy, and spirit that Sosai Mas Oyama directly taught our chair, Sosui Makoto Nakamura.
