Training at the 沖縄空手会館 (Okinawa Karate Kaikan): PART ONE - Report

This week I’ve been back in Okinawa training.

While Shotokan is ‘mainland Japanese karate’ our IKS style is deeply respected due to our old-school approach: both technically and in attitude/spirit.

Here’s a brief outline from my days training at the Okinawa Karate Kaikan.

基本 (Kihon)

In Okinawa karate tradition this sessions “Kihon” centered around 補助運動 (Hojo-undo). While I regularly use the sandbag, makiwara and weights in my daily practice, the training here always includes some ‘old school’ tools.


① 巻藁 (Makiwara)
Impacts with Seiken and Shuto.


② サンドバッグ (Sand-bag)
Renzokuwaza.


③ 握り甕 (Nigiri-game)
Unsoku with both Sanchin-dachi and Fudo-dachi.


④ 鎚石 (Chi-ishi)
Exercises in both Kiba-dachi and Shiko-dachi.

⑤ 石差し (Ishi-sashi)
Exercises in both Kiba-dachi and Naifanchi-dachi.


型 (Kata)

平安初段 (Heian Shodan).

鉄騎二段 (Tekki Nidan).

半月 (Hangetsu).

征遠鎮 (Seienchin).

舞鶴小 (Maizuru Sho).
In sum the training was focused on strength and conditioning for impact power; furthermore, the 力の強弱 (Chikara no kyojaku) — the ‘use of power’— via the utilization of solo kata practice.


While kumite was not directly addressed today, the aspects covered are clearly related to actual self-defense, which is the technical essence of 伝統的な空手道 (Traditional Karate-Dō).

The IKS (International Karate-Dō Shōtōkan) is moving forward here in Japan and aroun

d the world. I am sure that Asai Tetsuhiko Sensei would greatly approve of our technical standards and efforts.

Daily training and research

Some images from my two training sessions, on this 1st Day of July 2026.

In addition to daily training in the dojo I'm continuing my technical research into Karate-Do, especially in regard to classical waza as 'bujtusu'. This follows in the tradition of Asai Tetsuhiko Sensei, who sought the origins of Shotokan-Ryu and greater understanding of optimal human movement.

Indeed, (and following Asai Sensei's example) only from physical training can such research have meaning in our art, so nearly 45 years on, daily training with specific (and measurable) goals is, and has always been, my top priority. 

There will be some upcoming announcements regarding 2027 as soon as possible.

I wish you all good health and the very best in your Karate-Do training.  

押忍 !

Renshusei from Lubeck, Germany

Movement eight of 落葉 (Rakuyo) Kata.

Jan Kohberg from Lubeck, Germany, came for four days of Renshusei training between June 22nd and June 25th.

Besides working on subtleties of the core fundamentals of Shōtōkan Karate-Dō on the first day, the sessions were primarily focused on themes requested by Jan.

Namely, he wanted to develop his 自由組手 (Jiyu-kumite) skills and properly learn the Asai-ha Shotokan-ryu kata 落葉 (Rakuyo).

'Bunkai' of movement one: 落葉 (Rakuyo).

After some analysis of his movement and skills, I decided to primarily utilize 順路初段 (Junro Shodan) and 自由一本組手 (Jiyu Ippon Kumite) to lift his technical level.

Focal points were primarily Jan's 立ち方 (Tachikata) and use of 力の強弱 (Chikara no kyojaku).

Jiyu Ippon Kumite.

Rakuyo kata was particularly useful in regard to stances due its extensive use of 転身 (Tenshin).

Furthermore—as the name of the kata suggests (‘Falling leaves’)—relaxation and fluidity are absolutely imperative. I joked with Jan that the kata must not be ‘falling coconuts’; thereby, emphasizing the need for lightness.

In the Jiyu Ippon Kumite and Jiyu Kumite practice I focused on applying the principles from Junro Shodan and Rakuyo. This included the traditional use of 出合い (Deai), 体捌き (Tai-sabaki), 技の緩急 (Waza no kankyu) and so forth.

In addition to all the aforementioned points we also worked on the classical Shotokan kata 岩鶴 (Gankaku) to further enhance core stability/balance and 姿勢 (Shisei).

To conclude, over the four days it was great to see Jan improve in technical skill. This was the result of his diligent practice each day.

頑張ってください Jan、押忍!
