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.

Szczecin , Poland Seminar 2026: PART ONE — (Brief Overview)


The 2nd Seminar in Szczecin, Poland, was held on May 16th and 17th, 2026.

Once again hosted by ‘Klub KaratePomerania Szczecin’:


I was graciously taken care of by Paweł Karpow Sensei, Arsenij Karpow Sensei and Olga Karpow; furthermore, the members and supporters of the dojo.


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.



Overall, the seminar was a great success and professionally organized. It was also great to see the karateka who’ve really improved since last year. This is a joy for me as an instructor. Outside of the trainings I was very well looked after by Paweł Sensei and Arsenij Sensei, so I’m very appreciative of their kind hospitality.


Stay tuned, I will post some video footage soon.

姿勢と柔軟性

姿勢と柔軟性 (SHISEI TO JUNANSEI) literally translates as ‘Posture and softness/flexibility’.


Asai Tetsuhiko Sensei always greatly stressed these two aspects to me; furthermore, that they influence each other. Consequently, they are of great importance in the IKS (International Karatedo Shotokan).


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.


It is also weaker, more telegraphed, less smooth, and here’s the one: disrupts your posture.


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’.


We must keep in mind Newton’s Second Law…

F = ma (Force = mass x acceleration)

Renshusei from Vlijmen, Netherlands: Alex Hermans

Alex Hermans (6th Dan) came for his second RENSHUSEI TRAINING here in
 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.


The key point here is that both BUNKAI (Analysis) and OYO (Applications) were intensively covered, which is a strong trait of the IKS.


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!
