Increasing the knowledge base of Saitos

You will recall that Shihan Jan de Jong OAM 9th Dan commenced his training with the Saito brothers in Semarang Indonesia pre-WWII. Not much is known of the Saito brothers.

In the Jan de Jong Pre-War Years post, I referred to a possible/probable reference to the Saito brothers in 50 Years of Silence:

When De Jong returned to Indonesia after WWII, he tried to locate his instructors but no trace of them was ever found. This could be explained because they may have been Japanese spies. De Jong would suggest they may have been in the Japanese Army pre-WWII. This story is given a little more suk pport when Jan Ruff-O'Hearne (50 Years of Silence) writes about her time growing up in pre-WWII Semarang: 'Our friendly Japanese photographer turned out to be a spy too. He was the most popular photographer in Semarang.' Given the time the Saitos spent in Semarang, it may be they were former military and were called upon, as islikely of all nationals living in a country which is at war with their homeland, by the Japanese military prior to their invasion.

 One of the unintended and unexpected outcomes of creating this blog is that others who used to be associated with De Jong have contacted me to share relevant things with me. That brings me to the subject of this post; that a past student of Sensei Darryl Cook who contacted me with some references associated with the Saitos, in particular photographer-Saito.

Before we come to those references, de Jong shared with me a book he'd discovered that included a photograph of a street in Semarang taken by a photographer of the town/city named Saito. De Jong and myself visited that streets when we toured Java, Indonesia together. Apparently his brother used to ride his bike down the hill at full tilt and on one occasion ended up demolishing a flower stall.

'The photos in this report were shot by Saito, a famous Japanese photographer in Semarang at that time.'

'This is a brown and white photo made in the 20s. So it is about 85 years OLD . It shows a beautiful view of a Chinese Wedding Couple. This photo was probably taken by Saito & Co, Semarang , Java in Indonesia .'

Not much is known about De Jong's first jujutsu instructors, the Saito brothers. If anyone else comes across any other information, please contact me and I'll share with the readers of The School of Jan de Jong and add to the knowledge base thereof.

Shihan Jan de Jong's Legacy

It's 15 years to the day that Shihan Jan de Jong OAM 9th Dan pasted away. Many tributes are being posted on Facebook in honour of de Jong and his impact on people. This gave me pause to reflect on de Jong's legacy.

I have studied de Jong's jujutsu grading system. Not just engaged in it but really studied it. I used 'the core of all learning' to study his grading system. The core of all learning, as I explain in my The Science Behind Fighting Techniques manuscript that I have just submitted to a publisher, is the identification of similarities and differences. It was by comparing what we do with what others do that I gained enormous insights. I learnt more about what we teach by studying what others teach than I could have simply by studying what we teach.

His grading system is a remarkable achievement. It is one of the most comprehensive grading systems in the world. It is all the more remarkable in that he developed it from what I believe to be scratch.

In Jan de Jong's Unique Grading System, I explain how he uniquely included gradings in his grading system that examine a candidates knowledge of why a technique works and their teaching abilities. His grading system uniquely develops black belts who are qualified teachers who know why a technique works in addition to knowing how to perform the technique (a la Gracie and Gracie, Brazilian Jiu-Jitsu: Theory and Technique).

The grading system is unique in using the shinken shobu no kata method to examine student's technical abilities. The term was taken from judo, however, the shinken shobu no kata used by de Jong is different to that taught by judo. Judo's shinken shobu no kata is a true kata in terms of choreographed attacks and defences. De Jong's is a kata in the sense that there are prescribed attacks and defences, however, those attacks are delivered in a random order thus simulating a fighting environment.

This method is used at the end of each class with various variations. Attacks are initiated based on the instructor's signalling which the defender cannot see. The defender can defend with any technique or they can defend using only the technique prescribed by the instructor which the attacks vary.

This method is in between true kata and free fighting. It instills a 'one punch, one kill' mindset; a committed defence that is designed to finish the fight there and then which free fighting often does not. The closest I've seen to it is Kyokushin karate's one-step sparring.

What is de Jong's legacy? Kaizen - continuous improvement. Those who are teaching can teach what de Jong taught, but, is that living up to de Jong's legacy? De Jong's grading system was a first effort, a remarkable achievement but still a first effort. There are errors in both technique and theory inherent in that grading system, which are the result of the lack of information that existed at the time he was developing it. In the spirit of kaizen we can address those errors. We can refine his grading system; grading system 2.0. I think this is what he would have wanted. For us to adopt the spirit of kaizen which was how he lived his budo life.

I think that to honour de Jong is to 'see further than he did.' As Newton said, 'If I can see further it is only by standing on the shoulders of giants.' He was a giant; we need to study and learn what he built, and then build upon that.

Jan de Jong's Unique Why Gradings

I'm finalising my first book on the science behind fighting techniques and am working on the front end (preface and introduction) and the back end (conclusion). I've found that a citation from Gracie and Gracie's Brazilian Jiu-Jitsu: Theory and Practice expresses the mission of the book:



In virtually all the martial arts, black belt denotes the highest level of achievement. ... By the time the student attains a black belt his knowledge and skill are of the highest class. In addition, his depth of knowledge makes him a fully qualified teacher. Rather than merely knowing how to perform the moves, the black belt is expected to know why a given move works. That is, he understands the biomechanical principles that underlie the move. The principles of leverage, of body control and mechanics. This deeper knowledge makes him a far better teacher than someone who merely recounts a series of moves. Moreover, such knowledge allows him to invent new moves and combination and so develop a more personalised jiu-jitsu. (Gracie and Gracie 2001, 17) (emphasis in original)


While the expectation that black belts are fully qualified teachers that know why a technique works in addition to knowing how to perform it is laudable, it is definitely not realised in practice or the martial arts literature.

This is another unique feature of the teachings of Shihan Jan de Jong OAM 9th Dan. He uniquely attempted to operationalise Gracie and Gracie's expectations of black belts by including gradings in Ikkyu (1st Kyu; assistant instructor) and yudansha (black belt) gradings that examine the candidates knowledge of why a technique works. This included theory grades where candidates are quizzed on the theory of techniques. There are grades where candidates are required to demonstrate specified techniques and answer theory questions pertaining to those techniques and their variations; thus fulfilling both of Gracie and Gracie's requirements of a black belt. There is also teaching examinations where the candidate is assessed on, among other things, their knowledge of the theory of techniques.

The problem with these gradings, and why de Jong's goal is not realised in these gradings, is that the body of knowledge associated with why techniques work does not currently exist. My book sets out to start to fill the void that is that body of knowledge.

Having said that, it takes nothing away from de Jong's unique fledgling efforts in realising Gracie and Gracie's expectations of black belts.

Tsutsumi Hozan Ryu International



The jujutsu taught by Shihan Jan de Jong OAM 9th Dan was referred to as Tsutsumi Hozan Ryu (THR) jujutsu. De Jong began the internationalisation of his teachings in the early 1980s when he started conducting seminars throughout Western Europe and Australia.

De Jong’s jujutsu grading syllabus is one of, if not the most extensive martial arts grading syllabuses I have ever seen. The aim of the yudansha (black belt) portion of his jujutsu grading syllabus is not only to develop proficient (world-class) practitioners but also to produce proficient (world-class) instructors. To this end, the yudansha grades contain numerous parts that are specifically aimed at producing said proficient (world-class) jujutsu instructors.

Towards the end of his life, De Jong often discussed his ideas of developing two yudansha streams with me. He was never impulsive when it came to developing or changing his grading systems (he also developed aikido and pencak silat grading systems) and he used me as a sounding board for the development of his ideas about a dual-streamed yudansha grading syllabus. De Jong passed away (April 2003) before he could realise his ideas in this regard.

The impetus for De Jong’s dual-stream syllabus was the fact that certain individuals would never teach nor want to teach the jujutsu that they were so proficient in. Why subject those jujutsuka to the instructor-oriented gradings when they would never teach jujutsu? Why deny them the opportunity of grading shodan (1st Dan) if they did not have the opportunity to assist instructing classes (one of the grading requirements)?

Sensei Daniel Newcombe 5th Dan Tsustumi Hozan Ryu Jujutsu and 1st Dan Shotokan Karate (see right) is the driving force behind Tsutsumi Hozan Ryu International (THRI). Newcombe was introduced to De Jong’s jujutsu in 1986 and has been teaching THR jujutsu since 1996 and continues to train under De Jong’s son, Shihan Hans de Jong 8th Dan. Following Jan De Jong’s passing, Newcombe established Colosseum Martial Arts, of which he is the principal, and then THRI.

THRI was established in 2015 by Newcombe and Sensei Wim Mallens (see below), Principal Tadashii-do Karate ne Jiu Jitsu based in Rotterdam, The Netherlands, with Hans de Jong being appointed Patron of the organisation. Mallens has a long association with the De Jong family being the first to host a De Jong seminar in Holland when De Jong was denied that opportunity because he did not belong to any Dutch judo or jujutsu organisation. Mallens continued to host De Jong seminars annually for two decades.

THRI is a non-profit organisation formed to provide a forum and framework for the preservation of the original THR jujutsu system, techniques, method of instruction and standard of Jan de Jong and Hans de Jong. Other goals of THRI are to restructure and modernise the original THR gradings, standardise teaching practices for greater consistency in practitioner and instructor standards, provide pathways for clubs and Instructions to affiliate with THRI and introduce the grading and assessment framework within their own teachings.

In this way, Newcombe and Mallens are realising De Jong’s vision and are extending it further.

Another initiative introduced by Newcombe within the THRI syllabus is the separation of the weapons grades in the yudansha grades into a separate stream. In this way, those not engaged in the THRI jujutsu grading stream can obtain training and qualifications in the use of various weapons.

Newcombe has also tackled a dilemma that De Jong grappled with without coming to a resolution before he passed away. That dilemma was the transitioning of jujutsu yudansha in other systems into the THR (now THRI) system without compromising the high standards associated with THR/THRI. Newcombe has developed a bridging course that culminates in the awarding of a THRI shodan grade. Higher THRI yudansha grades are contingent on completing the instructor-stream grades which ensures that the candidate is familiar with the rest of the THRI syllabus.

The Science Behind All Fighting Techniques
Gracie and Gracie in Brazilian Jiu-Jitsu: Theory and Technique (2001) suggest that by the time a student attains a black belt their knowledge and skill are of the highest class and that their depth of knowledge makes them a fully qualified teacher. Further, they suggest that ‘rather than merely knowing how to perform the moves, the black belt is expected to know why a given move works. That is, he [or she] understands the biomechanical principles that underlie the move’ (emphasis in the original). While the expectation that black belts are expected to know why a given move works in addition to how to perform the move is laudable, it is definitely not realised if the martial arts literature is anything to go by.

De Jong’s original instructor-oriented gradings which THRI has isolated in a separate stream of gradings is a greater step towards realising Gracie and Gracie’s expectations that yudansha are qualified teachers, however, they can still be improved upon in order to realise Gracie and Gracie’s expectation that yudansha know the why in addition to the how of jujutsu techniques.

I am very excited by Newcombe’s THRI grading syllabus approach as it demonstrates the utility of the science that I have developed for a book that I have tentatively titled, The Science Behind All Fighting Techniques. The theory that I have developed provides the biomechanical (and other) understanding of all techniques taught by all fighting activities and relates it to practice in a meaningful way.

Classifying Uke Waza - He Was Onto Something





I am currently finalising a book on the science behind fighting techniques. After attempting to edit the chapter on blocking techniques I found I had to research, reflect, and re-write the chapter because it wasn't up to standard with the rest of the chapters in terms of technical content and challenging the orthodoxy of martial arts theory.

Blocking techniques - simple enough subject you would think, but not so as it turns out. When you review the martial arts literature and listen to various instruction, you see the conceptualisation of blocking techniques is riddled with inconsistencies if not down-right inaccuracies. I won't go through them all here as it takes an entire chapter in my book to explore them, however, I will focus on Shihan Jan de Jong OAM 9th Dan's classification of blocking techniques.

Before that, we need to establish the basis of any exploration of the concept of blocking techniques. Here I turn to Wikipedia:

In martial arts, blocking is the act of stopping or deflecting an opponent's attack for the purpose of preventing injurious contact with the body.

Anyone familiar with my work might be wondering why I am starting off any exploration of blocking techniques with a reference to the relatively unauthoritative Wikipedia. The answer is because it is the only definition or explanation of martial arts blocking techniques that I can find that refers to the purpose of preventing injurious contact with the body from an attack.

The question becomes, are blocking techniques being used to prevent injurious contact with the body? An evasive body movement (Japanese: taisabaki) moves a person's body off the line of attack. If a blocking technique is used in conjunction with an EBM, the question always has to be asked as to the purpose of the blocking technique. After all, it's not to prevent injurious contact with the body from an attack because the EBM takes care of that problem.

This is a question that is particularly relevant to the teachings of De Jong (his jujutsu, aikido, and pencak silat) as his methods extensively emphasise EBMs. But it's also relevant to all martial arts. For instance, I refer to an instruction from a book by the karate master, Hirokazu Kanazawa, where he describes the use of a low block and taisabaki against chudan zuki (middle punch). What is the purpose of the low block because the taisabaki takes care of preventing injurious contact to the body from the chudan zuki?

There are answers to that question, however, it should always be asked nonetheless. Unfortunately it may reveal a lack of real understanding of the methods being taught and that they are simply taught rote fashion.

Blocking techniques in the martial arts are often distinguished between hard and soft, direct and indirect, arresting and deflection, etc. ... Are deflections blocks? Not according to the common place meaning of the term block, but as is so often the case, the martial arts appears to have extended the common place meaning of the term to include deflections as blocking techniques, although some still do distinguish between blocks and deflections.

A common distinction is between hard and soft blocks with hard blocks being described as meeting force with force and soft blocks being deflections. This delineation is often used to support an argument of the superiority of soft blocks over hard blocks, however, the concept of hard blocks is often erroneous. More often then not the classic high, middle, and low blocks of karate are used as examples of hard blocks. However, they do not oppose force with force directly. They are in fact deflections albeit using more force than is normally associated with the deflection classification. There are very few 'stopping blocks' taught in karate or most martial arts. Gracie and Danaher in Mastering Jujitsu demostrate true stopping blocks (and interestingly do not include any deflections at all).

However, there is a trick in understanding how Gracie and Danaher's 'absorption blocks' meet force with force. A trick that  is clarified in my chapter.

De Jong provided six classes of blocks in his classification: pushing, pulling, hard, brushing, grabbing, and empty.

When I was being taught jujutsu, I was told by my instructors that this classification refers to the unbalancing methods used against moving attacks. For the most part they were not being used to prevent injurious contact with the body from an attack because the extensive use of taisabaki in our jujutsu takes care of that problem. While I could see pushing, pulling, hard, and grabbing blocks as being unbalancing methods against moving attacks, I couldn't see how brushing blocks and empty blocks were unbalancing methods.

A brushing block refers to light contact with the opponent's attacking body part in the same direction as the attack. It is not a deflection which applies force at an angle to an opponent's attacking body part in order to cause it to move off its trajectory (when a taisabaki is being used it's not moving the attacking body part off the line of attack because the taisabaki moved the body off that line). How does that unbalance an opponent?

An empty block is no block at all. Taisabaki is used exclusively to move the body off the line of attack to prevent injurious contact with the body. How does no block at all unbalance an opponent?

I won't go into detail, however, if I received an answer to my questions at all it was 'shoehorned.' At attempt at using flawed theory to fit valid practice.

As it turns out, De Jong never intended his blocking techniques classification to be a system of unbalancing methods against moving attacks. He'd developed the classification to describe all the methods of dealing with an attack in his pencak silat. The jujutsu instructors' had appropriated the classification and misapplied it. The misapplication has to do with the unique classification of unbalancing methods from hand and body grabs that are included in De Jong's jujutsu grading system.

But De Jong was definitely onto something, which I now only fully appreciate given my work on blocking techniques for my chapter. Blocking techniques block but most blocking techniques taught in karate don't block. Deflections are technically not blocks. How can empty blocks be blocks? The answer lies in uke waza.

Uke waza is a Japanese term used to refer to blocking techniques, however, uke doesn't mean blocking. It means 'to receive.' What method is being used to receive an attack? Is it an uke waza with or without an EBM? If a technique is used in conjunction with an EBM, what is the purpose of that technique because it is not to prevent injurious contact with the body from the attack because the EBM takes care of that problem? This then returns us to the possibility that these uke waza being used without an EBM are being used for two purposes; to prevent injurious contact with the body from the attack and for some other purpose.

Uke waza refers to 'receiving techniques.'

Nakayama explores the purposes of blocking techniques in the classic Dynamic Karate (none of which refer to preventing injurious contact with the body from an attack). It is enlightening to use the above theory when analysing Nakayama's 'six possibilities in blocking.'

De Jong's six blocking techniques classification is in fact an example of a systematic approach to uke waza, which extends beyond blocking techniques. The insights this approach affords then needs to be used to cast an eye over the De Jong jujtsu grading system. This would be applying and extending the work started by De Jong.

Two Sisters In The Resistance

I published previous posts about Hannie Schaft (the 'girl with the red hair') and the Oversteegen sisters and their involvement in the Dutch Resistance. Vice Netherlands published an interview with Freddie Oversteegen (right in 1945), the younger of the sisters, and refer to a new documentary on these extraordinary women who were only young girls when they fought during WWII: 'Two Sisters In The Resistance.' Let's hope we get to see it.

The Way of Kaizen

The Way of Kaizen is the title of my article published in this month's Blitz magazine. It is what I consider to be Shihan Jan de Jong OAM 9th Dan's legacy. Would love to hear some feedback on the article.
