why you don't want to miss this...


it's the ultimate deep dive

You've seen it all — Knife defense like competion karate, dramatised and overdone tanto demonstrations... and even the so-called realistic knife training: not what you're looking for.

How does fundamental principles sound?

With fundamentals, you'll GET IT: no more headaches when instructor A does it this way, and B that way. All you'll see is principles being applied. You can master your Tanto Dori execution, even when your opponent "attacks you wrong".

You discover intricate details of Wado's Tanto Dori at Budo Masters #2 — beyond form 🚀 

kote NAGE DORI for example...

Not only do you learn how to execute Kote Nage Dori and the wrist throw correctly...

...you also discover how to adjust if your opponent has a change of plans. 

Plus: how do you apply Kote Gaeshi when someone takes hold of you? After Budo Masters #2 you can SHOW answers like that — easily.

You walk away with a plethora of techniques and deep understanding. Plus: a precious memory of an intriguing and fun seminar too 👌

why we think budo masters #2 is gonna be absolutely awesome?


Wado is Jujutsu but...

Granted. There's loads of overlap when it comes to unbalancing the opponent, setups, positioning. And Wado's official paired Kata includes quite a number of Jujutsu techniques.

This one for example, from Hiki Tate Dori 👇

The truth is: Ishikawa sensei teamed up with a top Jujutsu instructor. They trained together to exchange techniques.

Ishikawa taught him better punching and kicking, while he learned sophisticated and intricate details you likely only know if you're practising these techniques like we repeat Junzuki.

This resulted in Ishikawa sensei knowing a number of variations on the techniques. It's why he could deal with a taller opponent, or one with animal-like strength.


❌ You can figure stuff out by yourself.

❌ You can go on Youtube and copy-paste what you see...

...or learn it directly from instructors with clear lineages to the founders:

✅  Ueshiba >> Mochizuki >> Kruyning

✅  Ohtsuka >> Suzuki / Jiro Ohtsuka / Kazutaka Ohtsuka >> Gertjan

✅ Ohtsuka >> Sakagami / Ishikawa >> AJ

here's what people say about our seminars

—every single time

Andreas Boger Wadokai Germany

I want to join again

I really liked you don’t just do techniques on AJ sensei’s count and get general phrases like “better your hip movement” or so (which I see at other seminars).

AJ teaches key points, watches your techniques and then he advances on those key points interactive.

I would like to join again a seminar with AJ and his crew, not only for the results, but also to just talk again with all of them. They didn´t play a role, they were authentic.

Neil Bennett 1st Dan

The Aston Martin of Karate teaching.....

I really enjoyed myself by receiving quality instruction balanced with patients and belief.

At no time I felt criticised. In fact, I always felt confident that every element was improving my standards as a student of Wado.

There was so much content to take away from the seminar, especially because their words hit home fast encouraging progression, confidence and self belief.

Even if they teach a form different than you're used to, the way how they explain just makes sense. It's logic, and easy to understand and execute.

Maarten Wadokai Holland

their teaching was harmonised so we could connect the dots instead of getting confused

I’ve been training with AJ sensei for a few years now, so I’ve seen my fair share of instructors. Budo Masters stood out as well prepared and thoroughly executed. The sensei’s taught principles and applications seamlessly, flowing from one exercise into the other. They lead the seminar together instead of taking turns just doing their type of Karate. That way, even lower grades could connect the dots and practise on their own level. Instead of being overwhelmed with many techniques, you could start seeing how the principles worked in different situations.

During the seminar I have learned a lot. And thanks to the support and personalized advise from the sensei I could emphasize on the parts I wanted and needed to focus on. I enjoyed the seminar and am looking forward to Budo Masters #2.

Mark Noorman 2nd Dan - Wadoka Holland

How A True Budo Event Should Be

I loved to experience how and where Wado and Jiu Jitsu strengthen each other, as I practice both. But above all: the atmosphere at Budo Masters was great. Everyone worked hard, had fun and helped each other. Instead of Edgar, Gertjan and AJ sensei saying their way is correct, they added insights and details to each other’s techniques.

To summarize: how a true BUDO event should be. We covered so many techniques and details, which are impossible to remember all. That’s why I’m happy to get access to the recordings as well.

Chris Whittam 3rd Dan

I take away specific tasks that I now include in my practice

It is clear AJ knows what he is talking about!

I was highly impressed with the technical content of both the techniques and his way of teaching. AJ guides and explaines in general as well as on a personal level - looking specifically for what I need.

That allows me to focus on how and what to move so that I can work on my own abilities.

His seminars give me loads of ideas and suggestions and I take away specific tasks that I now include in my practice.

All in all I have to say that AJ’s seminar is time well spent.

Dave Shephard 5th Dan - Spain

The Perfect Seminar

Great teaching! Not only does AJ know his subject, his passion shines through and his teaching ability is obvious for all to see. Put the knowledge, passion and teaching together and you have the perfect Wado seminar.

Fabio Luisa 1st Kyū, Italy

Informational, awakening and highly motivating

AJ and Sakagami sensei’s teaching is really involving, encouraging you to ask questions and the atmosphere is really nice.

Both instructors are extremely competent and skilled. They give clear explanations and plenty of valuable insights, providing me with the tools to improve.

I’m excited to share what I learned with my Sensei and Kohai and because of this seminar, I set my goals higher.

From now on for example, I'm working on the shoulder blade movement and the awareness of Seichusen following the advices and methods taught by AJ.

Albert Bouma 2nd Dan

You get cues and clues that make the difference

What you learn here will really take your Wado to a higher level.

I get deeper insights that I have never heard anywhere else.

Time is not just filled with exercises... Instead, you get clues that make the difference.

Every time they explain a number of other fascinating facets of the Wado.

Andy Ardelean 4th Dan

After AJ's seminars I always feel like I have taken my skill up a notch

AJ sensei always knows exactly what I need to focus on to take my karate to the next level.

He is the only instructor I know who focuses on key points rather than just form. That’s why you gain a lot of practical insights as well as theoretical knowledge, making each of his seminars a unique experience.

AJ sensei’s teaching method and demonstrations are also clear and logical.

After his seminars I always feel like I have taken my skill up a notch.

Jessica Lyhagen Wadokai Sweden

I'm Coming Back For More!

I travelled to Holland, hoping to learn a ”cleaner” technique of my Junzuki and get aware of my bad habits. AJ sensei without doubt exceeded my expectations be explaining and demonstrating in a straight and clear way. It gave me a lot of aha-moments. Splitting up Junzuki in parts was something I not been aware of before. The seminar gave me more tools to work with and enriched my foundation. There were a lots of tips and tricks, and the hip exercise we did is very useful for me. I would have missed it if I did not attend the seminar and it would be hard to get on my own. I already saw results at the seminar, so I'm confident I will gain even more taking the methods on board now that I'm back home. I highly recommend this If you want to improve your technique of your Junzuki. I`m definately going back for more, fact is that I have already asked when then next event is. In my opinion if you want to enrich your foundation this is a very good way of doing it.

Eco Kleefstra 3rd Dan

I discover something new every time

With Sakagami, May & AJ sensei you really dig into the core of Wado.

For some course you have to make time and this is one of them: I discover something new every time.

What makes it even better is the particularly accessible atmosphere.

He explains reasoning behind the execution and delivery as well
AJ not only gives step by step instructions to Wado, but also the reasoning behind the execution and delivery as well as the correct mental attitude required for the techniques of Wado Ryu.
Peter May
- 7th Dan

AJ is always probing into the deeper learnings of Wado

A.J.’s thirst for knowledge was apparent even in his younger years, always questioning, always probing into the deeper learnings of Wado. He has painlessly researched and cross referenced differences within the three main styles of Wado.
Nukina Nobuyuki

do you still have questions? 

Contact AJ at [info @ the-digi-dojo . com] if your answer is not here 👇

Q — I don't have a black belt, can I join?
A — Considering the topic it's advised to have some experience. But on the other hand joining seminars like Budo Masters is what creates your experience. What matters is that you're interested, and you are since you're reading this. So why not join 👊.

Q — What Martial Arts do you need to practise?
A — Any. Although the Knife defense format is Wado Karate and loads of Jujutsu techniques will be covered, it's about how you use your body and control the opponent.

Q — I don't practise Tanto Dori much, can I still join?
A — Many top instructors agree that Tanto Dori is an extension of Kihon Kumite. It embodies Wado's principles and makes it good training regardless of your experience. Even without any prior knife defense training, you can join. The format is taught so you can learn the skills, even if you're from another style.

Q — We have Tanto Dori, but what if our Kata is different?
A — You don't want to get confused, we get that. It's why we emphasise the why and how. And especially the applications, so you can take home what you discover and implement it to your Tanto Dori. Instead of convincing you our kata is "the right way", we show you the numerous variations of the techniques so you get deep insights. 

Q — I'm not clear on the format of the seminar...
A — You can expect this: For example, AJ teaches Ude Garami Dori, explaining the principles and key points that matter. But what if your opponent is taller, what if he attacks in a different angle by mistake, what if he resists, WHAT IF? And how can you apply variations Ude Garami Dori when your opponent takes hold of you? Those questions are answerd by Kruyning by sharing a plethora of techniques from Aiki and Jujutsu perspective.

Q — Is the same thing taught Friday and Saturday?
A — There may be small overlap, but the short answer is no. On Friday, AJ sensei shows other Tanto Dori than the ones he'll cover Saturday. Friday will be Kata geared to knife free fighting, where you utilise simple, easy to remember yet effective grip controls with your everyday Karate techniques. On Saturday, focus lies on sophisticated, effective and doable Aiki & Jujutsu techniques in official pairwork training fashion (no Krav Maga type all out rage training — it's clean and controlled).

Q — I don't have a Tanto, can I buy one?
A — We will have a few rubber and wooden Tanto in storage and for sale at The Budo Masters Event. We have several that you can borrow as well. Hit reply when you get email about your Ticket and ebook + video access in the member area.

Q — How do I get the bonuses?
A — You automatically get access after your get your ticket. The system unlocks your access in The Vault inside The Digi Dojo at the-digi-dojo . com. You can download the eBook from there and watch the videos.
