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!

2026 South African Renshusei: PART ONE (Overview and Images)



Wesley Dyssel Sensei (5th Dan) and his students from his dojo in Pretoria (www.kimekarate.co.za) came for IKS RENSHUSEI TRAINING here with me in Oita City.


Students from his dojo were:


Lesego Mabe (2nd Dan)

Sherilee Knox (3rd Dan)

John Kuhn (4th Dan)


Also, it was absolutely fantastic to have Jody Young Sensei (6th Dan) again, who is presently based in Canada. Needless to say, it was Jody Sensei and Wesley Sensei's second time here as Renshusei.


Overall, it was a wonderful time of high-level technical training and fabulous camaraderie.


The focus was on IKS Budo Karate in Kihon and Kamite; furthermore, the kata 舞鶴大 (Maizuru Dai) was trained in-depth. However, I will leave it there!

 

Accordingly, a brief video—subtlety reviewing the key points of the trainings—will be released on YouTube soon.


Lastly, I'd again like to thank and congratulate Wesley Sensei, Jody Sensei, John, Sherilee and Lesego for their studiousness, and wonderful spirit. Also, my deepest thanks to Jody Sensei. I deeply value all of your friendships and your Karate-Do.

OSU! – AB

Renshusei from Loxstedt (Niedersachsen), Germany (PART 1): Written Overview

Joshua Block (2nd Dan), Stefan Kurkowski (2nd Dan), Niklas Rudolph (1st Kyu) and Fabian Wolf (1st Kyu) came for two days as a 練習生 (Renshusei/Trainees). Their hometown of Loxstedt is located near Bremerhaven and Bremen.


It was the second time for Joshua to be a Renshusei here in Oita, but the first time for Stefan, Fabian and Niklas.


Based on their technical requests, I establised that 地面反力 (Jimenhanryoku), 腰の回転 (Koshi no kaiten) and 体の伸縮 (Tai no shinshuku) were the focal points they were seeking to better understand and improve.


Accordingly, I decided to primarily utilize 基本一本組手 (Kihon Ippon Kumite) as “Kihon training” to address the aforementioned three aspects; furthermore, practice basic 間合い (Maai). To expand on this, and to bridge to freestyle, 自由一本組手 (Jiyu Ippon Kumite) was also practiced.


Kata covered included 慈恩 (Jion), 壯鎭 (Sochin), and a requested  review of both 波手 (Roushu) and 舞鶴大 (Maizuru Dai), which they’ve learned at my seminars in Europe.


Like for other Renshusei participants, the focus was not on hard physical training, but on traditional ‘Budo Shotokan’ technical development; that is, boosted karate skill development and knowledge.


Our Renshusei Training Program here is now recognized all over Japan as extremely high level for instructors, elite athletes and any karateka seeking to really improve their karate technique. Applications to be a Renshusei must be made via email to: iksjapanhq@gmail.com


To conclude, I’d like to thank Joshua, Stefan, Fabian and Niklas for their efforts whilst here in the dojo. We also had many fun times outside of training as well. I wish all four of you the very best and hope to meet you again in the future.

Kihon Ippon Kumite as 'Kihon Training'

Today's training was focused primarily on KIHON IPPON KUMITE with attacks with (and defense/counterattacks against): JOUDAN (Jodan jun-zuki), CHUUDAN (Chudan jun-zuki), MAEGERI (Chudan mae-geri keage), YOKOKEKOMI (Chudan yoko-geri kekomi) and MAWASHI-GERI (Jodan mawashi-geri).

My focus was simply on precise Kihon coupled with a vast array of Unsoku and Tachikata for various transitions. Accordingly, this was my fundamental practice in this session.

To conclude, I went through several kata as depicted below. Three of each Sochin, Unsu, Maizuru Dai (also Jitte and Maizuru Sho).

Current events... Besides Japanese Renshusei, soon there will IKS International Renshusei here from South Africa, Canada and the Netherlands. After that, I will be heading to Poland to conduct a Traditional Budo Karate Seminar there.

Freital, Germany Seminar 2026: PART THREE - YouTube VIDEO ONE

 IKS (International Karate Shotokan) Technical Director, André Bertel (7th Dan Japan), conducted the 4th Budo Karate Seminar in Freital, Germany on March 14th and 15th, 2026.

It was once again hosted by the Shotokan-Karate-Club Freital e.V. (Kaminari-Arashi Dojo). Shotokan karate as Bujutsu was the main focus in both Kihon and Kumite; furthermore, the advanced Asai-Ha Shotokan-Ryu Kata 舞鶴大 (Maizuru Dai) was taught. This kata brought the Kihon and Kamite--technique, principles and applications-- seamlessly together. Emphasis on impacting vital points with 'old-school karate' weapons of the body such as Ippon Ken, Nakayama Ippon Ken, Kakushiken, Kakuto and various forms of Nukite were high on the agenda. Also, use of Teisho and the Tate Ken. In sum, this video is to provide the Seminar Participants with some subtle reminders of the key points taught.
Any inquiries about hosting Seminars or Booking Training (as a Renshusei in Japan) should be made to IKS Japan Sohonbu Dojo: iksjapanhq@gmail.com
