André Bertel's Karate-Do

Wednesday, 22 July 2026

Stefan Schulz (Shodan) from Northeast Germany visited Oita.

During his time here the focus was on the core 基本 (KIHON) of classical 松濤館流空手道 (Shōtōkan Karatedō), which is systematically covered in the IKS Shodan and Nidan grading syllabus.

型 (KATA) covered in detail included 鉄騎 (Tekki), 燕飛 (Enpi), 十手 (Jitte), and by Stefan’s request青柳 (Seiryu). As always both the 分解 (Bunkai) and 応用 (Oyo) were also clarified.

Insofar as 組手 (KUMITE) is concerned, the main focus was on applying kihon and kata techniques, principles and tactics.

It was a pleasure for me to see Stefan improve his Karate. Rather than detailing Stefan’s specific time here in the dojo, below are some images.

Lastly, I want to wish Stefan and his daughters a wonderful remaining time here in Japan. It was great to have you all here in Oita City.

今日で50歳になりました。

As a professional karate instructor, in addition to teaching Renshusei, I do my own self-training every day without compromise.

今日で50歳になりました (Today I turned 50 years old), which, of course—in the art of 空手道 (Karate-Dō)—is still a youngster.

On the subject of age Asai Tetsuhiko Sensei once said to me that: “competition peak is usually between your mid 20s and early 30s”. Whereas “…one’s actual Budō technical peak (for long-time practitioners) is from your 60s”.

This highlights that 'maturity of waza' can only attained through many years of technical refinement, and an experienced mindset. Yes, the old maximum is indeed true: 'Youth is wasted on the youth'.

With these points in mind, I remain inspired, just as ever, 'to challenge myself via daily training'. Again, to quote my late mentor, Asai Tetsuhiko Sensei: "Every day, the serious budoka must consistently seek improvement through the rigors of their personal keiko".

As I enter my "50's" on this day, I want to offer sincerest thanks to all of my seniors, peers and juniors (past and present): both here in Japan and around the world.
