The Birth of Shinkyokushinkai: From Mas Oyama to Kenji Midori

What is Shinkyokushinkai? The short answer is that it is a full-contact karate organization that inherits its training principles from Kyokushin Karate while keeping the core of basic training, real use of the body, respect for training partners, and refining the mind under the pressure of practice.

If you ask what Shinkyokushinkai is from a practitioner's point of view, the word means more than the name of an organization: it means a training culture that values the heart as much as technique. Students must train Kihon, Ido Geiko, Kata, Bunkai, and Kumite in order, rather than jumping into contact without a foundation.

At IMAC Dojo Bangkok, we explain this history to students from the start, because once they understand that the hardness of karate is meant to build discipline and self-control, they train with a safer and more sustainable attitude. Anyone looking for adult karate classes in Bangkok in particular should always start with the basics and a safe progression.

Who was Mas Oyama? That is the first question to ask before studying Shinkyokushinkai history. Oyama made Kyokushin famous as a karate system tested through full-contact sparring, conditioning, and the courage to face real impact, at a time when much karate emphasized form and stopped punches before real contact. Oyama set out to prove that a martial art must stand on the reality of impact.

The history of Mas Oyama, founder of Kyokushin Karate, is often told through mountain training, tests of endurance, and the building of Kyokushinkaikan into a worldwide organization. Sources like the Official Mas Oyama History record key moments, such as the expansion of its dojos and the opening of the headquarters in 1964, a milestone of its international growth.

More important than the legend is the lesson that remains: karate is not only about defeating other people but about defeating your own fear, laziness, and hesitation. That is why the history of Shinkyokushin karate must always start from understanding Kyokushin.

The history of Shinkyokushin Karate cannot be separated from the transition after 1994. After Mas Oyama died that year, the Kyokushin world did not stand still. It went through a major period of change, with questions of succession, executive authority, and organizational direction, and many groups had to choose how to preserve the core of the art while the world changed.

What is WKO Shinkyokushinkai? WKO stands for the World Karate Organization, which gave Shinkyokushinkai a more international structure and clearer management and communicates its ideals through the Kokoro symbol, the character 心, meaning heart and mind. Interviews and news on the World Karate Organization official site show that WKO talks about more than competition: it also stresses manners, budo, and raising disciplined young people, which matches the approach IMAC Dojo takes with children, adults, and families in Bangkok.

Who is Kenji Midori? He is one of the defining leaders of modern Shinkyokushinkai. Known as a small fighter who stood out on the open-weight stage, Midori led many practitioners to believe that technique, timing, courage, and heart can make up for a disadvantage in size.

Kenji Midori, the 1991 Kyokushin world champion (winner of the 5th Kyokushin World Tournament), matters for more than the trophy. The title became a symbol that a smaller karateka can stand on a big stage through meticulous training and a mind that refuses to give up.

For students who started late, are small, or lack confidence, Kenji Midori's story changes the question from 'Am I suited to karate?' to 'How can I train to get better step by step?', which is a far better question on the path of budo.

The difference between Kyokushin and Shinkyokushin is best understood as a difference in organization and identity rather than a rejection of the original training roots. In basic technique the two clearly share the same root, but in organization, symbols, and the way it speaks to the modern world, Shinkyokushinkai has a clearer identity, especially through Kokoro and the idea of Master Our Mind.

Kokoro (心) is at the heart of how Shinkyokushinkai communicates, because the word does not only mean the heart in an emotional sense. It also covers the mind, intention, courage, and knowing how to govern oneself. Hard training therefore is not meant to build aggression, but to let the student see themselves more clearly.

In the Shinkyokushin Karate classes at IMAC Dojo we translate this idea into real practice: stand firmly, breathe properly, understand distance, respect your training partner, and stop when it is right to stop. Children practice discipline, adults practice focus, and parents see progress they can point to.

Learning Shinkyokushin karate in Bangkok is rarely only about how to kick and punch. People who look for it want to know whether the course fits real life, whether it is safe for children, and whether adults can start. IMAC Dojo's answer is yes, you can start, provided the training goes step by step with an instructor overseeing the details.
