Physical and mental training

Regardless of age, we support those who try to become physically and mentally strong. Instead of focusing merely on the never-give-up spirit, our practice is reasonable and safe. Students learn basics first, while those who are interested join light sparring wearing protective gear.

Self reflection

In our modern society with excessive information, we have to cultivate decisiveness for making many decisions. What do I really need? With meditation without using any mobile devices or PCs, why don't you carve out time for your self reflection?

Enjoy life more than now

Having another stage in your life different from that of business can double your joy in life.

Many members have started learning karate as a new hobby after retirement. Never too late to start something new.

Legend Mas Oyama

Kyokushin karate became popular with a comic series called "Karate Baka Ichidai" (Karate for Life). Many people who used to want to practice karate but had no opportunity to do so or those who used to have a scary image in karate have started coming to our dojos to practice karate.

Features of Shinjuku dojo(Nakano-sakaue station)

1. 95% had no experience 

Beginners can practice at ease with our detailed instructions, which are given by our richly experienced instructors who can teach those who are beginners to those who are karate athletes reaching the national level in Japan. Our dojos are filled with an active and open atmosphere.

2. Work out happily 

Though necessary for body, some training menus are too tough to continue alone. But such menus can turn to fun when worked out together. You can enjoy karate practice continuously with our balanced course based on serious training and light training.

3. A clear goal to continue your training

Passing the grading session that is conducted once every four months changes your belt color.

The new color of your belt proves what you have achieved.

Wearing a new belt refreshes your mind.

Those who are interested can also take on more advanced challenges including participation to a match or a championship tournament.
