André Bertel's Karate-Do
This site is based on my daily practice of Shotokan Karate-Do here in Oita City, Japan. More than anything else, unlike the majority of other karate websites, this page is primarily dedicated to Budo Karate training itself; that is, Karate-Do as a vehicle for holistic development.

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

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).

Szczecin , Poland Seminar 2026: PART TWO — (YOUTUBE VIDEO)

Szczecin , Poland Seminar 2026: PART ONE — (Brief Overview)
Besides Karateka from Poland, practitioners from Italy, Turkey, Germany, Czech Republic, France and England attended.
基本 (KIHON): My focus was on improving the participants “…natural energy via柔軟性 (Junansei) ‘softness’; 地面飯力 (Jimenhanryoku) ‘ground reaction force’; and 重力 (Juryoku) ‘gravity’”.
This, as always incorporated 転身技 (Tenshin-Waza), which were largely introduced into mainstream Shotokan by my teacher, Tetsuhiko Asai Sensei. Needless to say, these techniques and exercises enhance skill in balance, 腰の回転 (Koshi no kaiten) and so on. What’s more, they are particularly effective for defenses/attacks to the side and rear.
型 (KATA): By special request from Paweł Sensei, I taught 鶴翼二段 (Kakuyoku Nidan) kata, which he already practices, but wished to investigate more deeply. Accordingly, besides the solo kata itself, 分解 (Bunkai) and 応用 (Oyo) we’re well covered.
In all three Kakuyoku kata it is essential to maximize the ‘cranes wings’ actions, especially in regards to the use of the shoulders and elbows. Also, repeating myself from past articles here, but the “Kakuyoku” was a samurai battlefield strategy.
Insofar as 組手 (KUMITE) is concerned, I’m continuing on my mission to teach “…the Ma’ai of Jissen-Kumite”; that is, “to always execute techniques from the distance to cause maximum damage. Aspects of the trained kata and Kihon were seamlessly incorporated here.

姿勢と柔軟性
姿勢と柔軟性 (SHISEI TO JUNANSEI) literally translates as ‘Posture and softness/flexibility’.
While I could cover any number of karate-waza, 前蹴り蹴上げ (Mae-geri keage) vividly highlights the harmony between one’s ‘shisei’ and ‘junansei’. This is simply because the posture is very easy to analyze.
Before that I’d like to, in layman’s terms, establish what is meant by 'Shisei' (Posture) and 'Junansei' (Softness/Flexibility).
姿勢 (SHISEI)
The baseline or reference point for all postures in Karate-Dō is the vertical and horizontal alignment of: (1) the pelvis/hips; (2) back; and (3) head/neck. Please note, this is imperative in ‘foundational karate’; however, as insinuated before, is merely the main point of reference, which means deviations are natural and critical for the optimal instinctive responses in self-defense.
柔軟性 (JUNANSEI)
This is being in a state of muscular relaxation, to remain flexible, light, speedy and adaptable. In particular, this requires avoiding conscious use of the muscles and, instead, primarily focusing on using the joints (thereby, only utilizing the muscles required to make any given movement). This requires that one maximally employs 締め (Shime) to make "...the loading of techniques as compact as possible".
So, how do these two aspects harmonize or, for that matter, negativity influence each other? This was well investigated by Nakayama Masatoshi Sensei and expanded on by mentor, Asai Tetsuhiko Sensei.
Let’s return to Mae-geri keage as a case study.
The usual stationary practice in classical Shōtōkan-Ryu is to stand in heisoku-dachi and zenkutsu-dachi (both with gedan kakiwake-gamae).
However, today please consider standing in renoji-dachi, but still with with gedan kakiwake-gamae.
Firstly, Try a ‘strong kick’ from this position with the rear leg. The application of conscious muscular force will firstly result in a comparatively slow and stiff kick, also a shorter kicking action. But that’s not all.
Next, try to concentrate on maintaining perfect posture. Play special attention to face/head/neck not moving. As the picture shows this is not easy, when the kick is executed at high speed, and especially when fatigue sets in: after many repetitions.
Raise the kicking knee as high and tightly as possible, and lightly/speedily whip the leg out, back and back to the floor.
If you: (a) remain deeply relaxed; (b) have kakato-chushin with your weight on the heel of the sasae-ashi; and (c), your posture is not influenced, your kick will be very effective, as it will be faster, smoother, more flexible, be more adaptable, have more impact, have a bigger scale, be 100% harder to be read by your opponent, and will not waste energy.
What’s interesting about this, if you concentrate on relaxation and just keeping your face set, you will immediately feel the connection. It’s as if facia also comes into play.
Conclusive remarks
High level budo karate preserves 古流武術技 (koryu bujutsu-waza)—old school bujutsu techniques. This is underpinned by harmoniously utilizing “…softness, natural energy and postural awareness” to generate explosive impact power.
Asai Sensei always taught me, this is like the Chinese seven jointed, the nunchaku and his favorite weapon, the kusarigama.
Brute muscular force is therefore not only inferior and unsophisticated, but also a barrier stopping high-level development.
I’d like to briefly mention about the 'psychology of precise posture and being in a state of relaxation'. It also greatly increases one's situational awareness and, therefore, 'reactivity'. Thus, muscular tension not only results in a physical fight against oneself, but it also results in the mental state of what is loosely termed ‘tunnel vision’.
To conclude, as we get older ‘hard karate’ is not only bad for the body, but also unsustainable for on-going improvement. In fact, it will result in regression. However, even for young people in their physical prime, ‘hard karate’ will greatly limit their skill development. This is because the term ‘hard karate’ is misleading. The real term for hard karate is actually ‘incorrect karate’.

Renshusei from Vlijmen, Netherlands: Alex Hermans
Oita.
Training over ten days (for two hours each day).
By Alex’s request I covered the key aspects of Budo Karate Kihon, primarily the use of relaxation and snap, ground power, various ways of using the hip, the contaction and expansion of the body, and so forth.
Many kata were practiced, but most deeply worked on were:
順路 (Junro) for improving kihon;
半月 (Hangetsu) his tokuigata for Dan Examination;
水手 (Suishu), 波手 (Roshu) and 火手 (Roushu) for utilizing/applying ‘natural energy’; and
舞鶴大 (Maizuru Dai) by Alex’s request, via my Technical Seminar in Freital, Germany earlier this year.
For kumite, I focused on Budo Karate ‘maai’ and hitting from angles which blindside the opponent. This ‘unpredictability’ was at the heart of Asai Tetsuhiko Sensei’s karate.
In sum, I’d like to congratulate Alex on his efforts. He has immensely improved from last year, and during this Renshusei, I saw him improve much more again!
Looking forward to seeing you again Alex!
押忍!!!
