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!

19th Anniversary of my Karate-Dō Blog

Assisting my late teacher, Asai Tetsuhiko Shihan.

 Today marks the 19th Anniversary of this Blog. Three months after moving back to Japan, in 2007, I decided to create a free online resource for traditional Budo karateka.

Just over a year before (in February 2006) my dojo in New Zealand had its 10th Anniversary; I attained 六段  (Rokudan); and at the conclusion of the year, I married Mizuho.



Most sadly, on August 15th of 2006, my mentor Asai Tetsuhiko Sensei passed away. It just so happens that August 15th is an extremely significant day here in Japan. It is 終戦記念日 (Shūsen-kinebi), which is the Memorial Day marking the end of WW2. We must not forget history, and we must never forget those very special people in our lives who depart before us. Every training session, every day, I think of Asai Sensei. I’m deeply grateful for his personal mentorship.
Over the years I won a few championships, including here in Japan, but tournament success was never my main focus. They were merely 'Shiai' to pressure my training and test my skills.


Reflecting on the 19 years of this blog— ‘ABKD’ (André Bertel’s Karate-Dō)—it reminds me that ‘Karate-Dō, like other arts, it endless”. It is a journey, not a destination; however, to maximize our training we must constantly seek heightened skill”. As Asai Sensei always said to us: “Step-by-step”.



Indeed, this is physical, but ‘in the constant seeking of technical improvement’, it simultaneously fosters mental discipline and fortitude. Again, Sensei always stressed: “Never give up!”
Sharing Traditional Budo style Shotokan, here in Japan, and around the world.

Accordingly, we must never keep applying 押忍の精神 (OSU NO SEISHIN): ‘The Spirt of Perseverance’.


Lastly, I am very grateful to more than two-million people who have visited this niche site over these 19 years. Also, to the many karateka here in Japan, and around the world, who have supported my efforts as a professional karate instructor and practitioner.


My wish is that everyone is healthy, happy and improving through training.

よろしくお願いします、押忍!

Old school Shōtōkan: Linking present-day Karate to 'Bujutsu' via the Koten-gata


This week's training, since returning home to Japan from Europe, has been dedicated to the training of 古典型 (Koten-gata)—and their respective 分解 (Bunkai/Analysis)—especially from the vantage point of old school Shōtōkan 基本 (Kihon); hence, the title of this post.


Each day this week, so far,  has been a different kata...


Sunday: 明鏡三段 (MEIKYO SANDAN)
46 movements with kiai on actions 29 (右縦拳下段逆突き) and 42 (右足底三日月蹴り、左掌当て).


Monday: 安三 (ANSAN)
41 movements with kiai on action 40 (底掌合わせ突き).


Tuesday: 掌手小 (SHOTE SHO)
51 movements with kiai on actions 24 (横貫手上段諸手突き) and 49 (横貫手上段諸手突き).


Today (Wednesday):  舞鶴小 (MAIZURU SHO)
74 movements with kiai on actions 60 (左縦一本拳中段逆突き同時に右上段内受け) and 72 (右横貫手上段弓突き).


From next week I will return to my standard training regime of 基本 (Kihon), 型 (Kata) and 組手 (Kumite). However, as this post highlights, it is also important to mix up one’s training regime. This not only keeps things very interesting—and is ‘fun’—but, quite often, it also unveils (or elucidates) weaknesses.


Needless to say, from a traditional Budō Karate perspective, that why the Koten-gata greatly enhance standard contemporary Shōtōkan Karate-Dō. Moreover, strongly link our style and technical skill/knowledge to pre-WW2 武術空手 (Bujutsu Karate).

The difference between ‘control’ in 競技 (Kyōgi-karate) and 武道空手 (Budō-karate)


The concept of ‘control’ in traditional style karate 組手 (kumite) is by no means universally the same. On the contrast, there are two very approaches, which are completely incompatible.


This applies in all forms of dojo kumite, from yakusoku-kumite right through to jiyu-kumite; and accordingly, in tournaments as well.


Some may claim that it is possible to do ‘both forms of control’, and it is; however, one must understand that one method trains a bad habit in the ‘martial arts sense’ and the other is the correct ‘traditional way’.


It is here that I need to clarify the term 伝統的な (Dentōtekina) or ‘traditional’ as this term is sometimess hotly contested.


Rather than think of karate styles, one must think of the origins of karate, it’s objectives, it’s purpose. In the physical and technical sense, it was for real world self-defense. Therefore, controlled techniques in karate must not compromise maximum effectiveness.


Here is where Kyōgi-karate and Budō-karate become like oil and water.


In kyōgi-karate kumite to merely reach and touch opponent is enough to ‘score a point’; however, in budō-karate, without the potential to cause maximum damage to the respective target, the technique lacks the maai to have kime. Thus, it is non-technique, a “miss”.


The Budō/Traditional karate 技 (waza/technique) inherently requires the power of the entire body, especially from the legs and hips. In particular, in the case of the hips, they must be fully committed to the action.


Accordingly, the ‘control’ in budō-karate is arresting the extension of the attacking limb. If this is not done, the technique will impact with full-power. Thus, the ‘control’ is not tagging the opponent for arbitrary points but, rather, controlling oneself from following through.


In this regard, when we say hit the sandbag (or other impact apparatus) with full force, our technique does not change from when we engage in ‘Kumite’. This is because we simply do the same action but allow full extension of the limb: instead of adhering to the sun-dome methodology, which governs ‘control’ in the aforementioned manner.


This why we say: ‘Kihon, Kata and Kumite are one”.


So, is it possible to do both budo and kyögi/sports karate kumite? Well, yes, it is; nevertheless, they are vastly different.


A top-level traditionalist, if competing in an elite sports karate event “…will be unable to win if they utilize budō-karate technique”. This is because tagging is faster to ‘touch’ and also far easier to immediately retract out of range.


That being said, I’ve seen and coached karateka who have gone on to excell in both forms of kumite.


To conclude, in our organization the 国際空手道松濤館 (IKS — International Karate-Dō Shōtōkan) we practice ‘Traditional Budō Karate); that being said, we also have many karateka who enjoy Sports Karate. Of course, we respect and support each karateka’s individual paths.




The most important thing is training; moreover, understanding that how we train determines what our karate can do.

Consequently, irrespective of one’s objectives, I believe that all karateka (even if sports karate success is their aim) must have a strong base in TRUE KARATEDO, which is 伝統的な武道  (TRADITIONAL BUDO). Ironically, especially in 型  (Kata), this approach is far superior to the sport-centric approach.


Lastly, I must emphasize again that technical essence of Karate technique is Kime. To quote the late master, Nakayama Masatoshi Sensei: “Irrespective of how much something resembles Karatedō, without Kime, it is not”. A kimewaza, in kumite, can only be achieved “…if it possesses/has the potential to finish the opponent”. In sum, this is constant technical aim—in the traditional training/practice of 基本 (Kihon), 型 (Kata) and 組手 (Kumite): 一撃必殺 (ICHIGEKI HISATSU).

2026 International Seminar in BRAGA, PORTUGAL: Report and YouTube Video


PLEASE NOTE - THIS VIDEO IS SIMPLY TO GIVE 'THE SEMINAR PARTICIPANTS' SOME SUBTLE REMINDERS OF WHAT I TAUGHT.


 Over the weekend of June 6th and 7th (2026) I conducted a third Technical Seminar in BRAGA, Portugal. The first was seven years ago in 2019 and the second in 2023.

Hosted by KARATE BRAGA (https://www.karatebraga.com) the event marked the 25th Anniversary of the dojo and 25 years of club founder Francisco Pinto Sensei (5th Dan) teaching Shotokan.
Besides Francisco Sensei, Paulo Araujo Sensei (4th Dan) and Tiago Gomes Sensei (2nd Dan), I’d personally like to thank all the families and members of Karate Braga; furthermore, all of participants from other Portuguese clubs and from around Europe.
Likewise, there was support from the Municipality of Braga; the Union Junta de Freguesia de Real; Dume e Semelhe; as well as all the business partners who greatly contributed to the organization and success of this international traditional karate event.
While I won’t go into the specifics of the seminar (these are for those who trained), the overall themes were:
Relaxation smoothness, flexibility and maximum velocity: namely via 柔軟性 (Junansei). Optimal use of one’s body mass via 体の伸縮 (Tai no shinshuku) and 地面反力 (Jimenhanyoku), 重力 (Juryoku) and 腰の力 (Koshi no chikara). Traditional Budo Karate 基本技 (Kihon-Waza): Pre WW2 karate and post WW2 scientifically-based refinements. 古典型 (Koten-gata): 掌手大 ( SHOTE-DAI) via request from dojo chief instructor, Francisco Sensei. 武術空手における組手の間合い (The ‘Maai’ for Kumite in Bujutsu Karate); that is, the constant aim of ‘seeking to finish the opponent with a single action’.
To conclude, I was very happy to hear so many people hoping for another seminar in the future, which is a great honor for me. It is indeed a great opportunity to share Shotokan directly from Japan with those who seek the TRUE WAY OF TRADITIONAL BUDO KARATE.


In these regards I can only say to everyone involved ありがとうございます (Arigatou Gozaimasu —thank you very much) and 押忍 (OSU)!

The quality of the methodologies which 'generate and apply' the various waza of Karate-Do

Daily self-training training - May 25th, 2026.     
常行五 勢 (JOKO GOSEI) KATA.



While the foundational forms of power in classical Shotokan Karate are 腰の回転 (Koshi no kaiten) and 運足 (Unsoku), what underpins these ‘basics’ is 地面反力 (Jimenhanryoku) which is ‘reactive ground force’ or ‘ground power’. It goes without saying that “…to use the hips fully with ground power” requires 体の伸縮 (Tai no shinshuku). This is especially in regard to the stretch of the rear leg.

Of course, the rotation of the hips is merely the base form. In actuality, 腰の力 (Koshi no chikara) is the ‘overarching term’ which includes rotation, but also encompases the horizontal ‘tilting of the hips’, the dropping and rising of the hips, and diangular usages.

This reminds me of training sessions with Isaka Akihito Sensei during the period of the Matsuno (Asai Sensei) JKA period. He summed this up by stating ‘… the hips must be used like a ball”.

When looking at 運足 (Unsoku) we must obviously consider it from both a defensive and offensive perspective.

Defensively: so we can evade an opponent and/or positions ourselves ideally for a counterattack. Examples of this are 足切り替え (Ashi kirikae), 体捌き (Tai sabaki), 出合い (Deai), etcetera.

Offensively: the prime objective is the maximum transfer of one’s mass into the respective target for as much impact power as possible. In this case, we must again reference Newton’s second law. This is typical Shotokan ‘Big hit’.

However—what is often overlooked—is “..the speedy delivery of light waza”, which can also be effective (and sometimes moreso, and more appropriate). For example, very light tsuki, such as rapid kizami-tsukiwaza. Such techniques are rarely ‘finishing blows’ but cause surface damage to an opponent (especially the eyes and nose). Needless to say, these waza can cut up the opponents face disturbing their vision, and set up a power shot, if required. From personal exeperience, as a doorman and later a bodyguard, I found that sometimes these light hits could dissuade continued fighting.

That being said, the training of power techniques is the priority, as they are the ‘finishing waza’; hence, their priority in Shotokan-Ryu.

Another aspect I must mention here in both the use of Koshi and Unsoku is found in Goju-Ryu. Here in Oita, Sato Shigenori Shihan (8th Dan JKF Goju Kai) has guided me in aspects of traditional Naha-Te.

His use of power utilizes internal energy, connectivity, the dropping center of gravity, naturalness, relaxation and wave power. Furthermore, as you will know, rotation in Goju  is far less than in Shotokan. Taken as a whole, tremendous power is generated from very subtle actions. Needless to say Master Sato’s Karate is magnificent.

Ironically, his karate teaching perfectly ties in with the 白鶴拳 (Hakutsuruken) aspects of Asai Tetsuhiko Senseii’s Shotokan.

To conclude, all of the aforementioned points highlight an important aspect of Budo/Bujutsu Karate (irrespective of kaiha/ryuha): “One must learn various ways to optimally harness and apply maximum power when required; moreover, that highest level is relaxed, smooth and natural actions”. Furthermore, the application of techniques must be adaptable in the real world. As Asai Sensei used to say: “Most people only have a facsimile of karate”. That is, only the external performance. This is merely ‘karate movement’ or ‘sports’. Thus, the most important aspect of Kihon is “the quality of the methodologies which generate and apply the various waza”.

Consequently, this is why seeking the very best mentors is so important in the art of Karate-Dō.
