Also Recommended: Tachikawa Practice Sessions with Shihan Yui
Separate from the Hamai Group's own programs, Shihan Satoshi Yui hosts the Tachikawa Practice Sessions at his Jinshin Dojo in Tachikawa, Tokyo. They are his own sessions, open to practitioners beyond the dojo, and they are known for their depth.
- Original Kyokushin karate. The sessions pass on the training system practiced during Sosai Oyama's lifetime, taught by an instructor who trained as the Sosai's uchi-deshi (live-in student) and has taught in more than 30 countries.
- Substance over quantity. On September 27, 2026, with members of the Hamai Group among the large turnout, the session was extended by 30 minutes to run two and a half hours, to match the participants' enthusiasm.
- Held on Sundays. Upcoming dates: 2026: Oct 11, Oct 25, Nov 1, Nov 15, Nov 29, Dec 6, Dec 20, Dec 27 / 2027: Jan 17, Jan 24.
Dates are as announced by Jinshin Dojo on September 26, 2026. For start times, venue and how to take part, please check with the dojo: Jinshin Dojo website ／ About Shihan Yui and Jinshin Dojo.

What Is Authentic Kyokushin?
Practical, direct-contact striking in which bouts are decided by landing blows. And the bearing of a martial art that begins and ends with courtesy. More than flashy techniques, what we value above all is the unbroken repetition of the basics: punches, kicks, and blocks.
Training content and times vary by dojo. For details, please contact the individual branches and dojos.
