The Development of the Jan de Jong Jujutsu Grading System 5.0: Sandan Part 1

The final technical grading in the Jan de Jong (JDJ) jujutsu grading system is sandan.

This fits with the narrative that the final technical grading in the Tsutsumi Hozan Ryu (THR) jujutsu grading system that JDJ was involved in with his original jujutsu instructors, the Saito brothers, was sandan.

There are only five people who have completed the technical grading system of the jujutsu taught by JDJ under JDJ, and which is apparently part of the THR tradition, are Peter Clarke, Robert Hymas, Paul Connolly, Greg Palmer, and myself. Me - their student. The only 'student' to complete the JDJ jujutsu grading system under JDJ.

Standing and not standing, Greg Palmer and me respectively.

There are some other 'students' that have been graded sandan, and higher, in the JDJ tradition through a JDJ ryuha, however, that grading system is compromised in relation to JDJ's grading system because the head of that ryuha did not grade above shodan under JDJ. Consequently, their nidan and sandan grades contain less and are different to that taught by JDJ. And even in that ryuha's shodan grading, there are mistakes.

You will recall from previous posts that Clarke, Hymas, and Connelly were the first through the nidan and sandan gradings because they were to be JDJ's legacy. Greg and I came through after the first trio. It is important to remember that fact because, among other things, it gave JDJ a chance to review the nidan and sandan gradings that he had developed and to change (improve) upon them. 

This post will be done in two parts because the sandan grading contains 12 parts, whereas shodan and nidan were long enough with nine parts.

You will recall from previous posts that the structure of the dan grades was set with JDJ's initial grading system, the kyu grades, with ikkyu being the instructor grade. 

Note: There is no shinken shobu no kata part in sandan. This is the only grading in JDJ's grading system that does not contain a reflex/shinken shobu no kata part to the grading.

The grading requirements and description of the different parts are taken from Jan de Jong: the man, his his school and his ju jitsu system (Jan de Jong Self Defence School, 1997 (p.52)).

Part 1 Kime no Kata

'Explain the theory and answer questions on demonstrated defences.'

You will recall from previous posts that kime no kata is generally considered to be a revision grading within the JDJ jujutsu grading system. According to the glossary in the abovementioned book, it means 'form of agreement (attack and defences are agreed upon and so form a demonstration)' (p.58).

This grading consists of 57 attack-defence combinations, none of which have been included in any other grading within the JDJ jujutsu grading system; they are all new attack-defence combinations.

When Greg and I did this grading, JDJ asked no questions. Greg was disappointed because he was prepared and wanted to discuss the theory behind the defences. He asked JDJ why he hadn't asked us any questions. JDJ said that he didn't have to because he knew that we know the theory.

I would have liked to have heard any questions that he asked of Clarke, Hymas, and Connolly, and their answers.

Part 2 Ju Jitsu no Jitsuen

'Arrange a 10 minute demonstration on a topic given by Shihan Jan de Jong using only yudansha. Twenty minutes preparation time will be allowed.'

This part follows on from the ju jitsu no jitsuen part in the nidan grading.

The way JDJ conducted this grading was, during the Friday night instructor's class, he'd simply inform the candidate (Clarke, Hymas, Connolly, Palmer, or myself) that they would be putting on a demonstration using yudansha that were attending the class that night. Literally, only 20 minutes to prepare on a subject of JDJ's choosing with the performers present that night.

It was an interesting grading for me as I was instructing my former instructors what to do. I was assessing their capabilities in terms of what they could perform adequately. That was a challenge in itself.

Part 3 Taisabaki no Kata

'Prepare a kata to show the different variations of the body movements.'

The five body-movements are the five main body-movements (taisabaki) taught by Yoseikan Budo (YB).

I did a bit of 'teach the teacher' in this grading. You will recall from a previous post:

The dodging body-movement was included in this grading due to Greg Palmer's lobbying. I argued that dodging was simply a variation of either flowing or sliding body-movements, which I went on to demonstrate in my taisabaki no kata grading in sandan. It was a 'teach the teacher' moment, however, even though they agreed with me, it is still retained in this grading.

Part 4 Sutemiwaza no Kata and Taoshiwaza no Kata

Sutemiwaza no Kata: 'Demonstration and full explanation of the theory of 20 different sacrifice throws and their variations.'

Taoshiwaza no Kata: 'Demonstration and full explanation of the theory of 20 different takedown techniques and their variation.'

This part of the grading is pure YB. 

You will recall from a previous post that I obtained a copy of Minoro Mochizuki's book, Nihonden Jujutsu, from Jan-Erik Karlsson while assisting JDJ teaching for him in Sweden. I gave a copy of that book to JDJ.

The book has many hand-drawn images of techniques. JDJ photocopied 20 of those techniques for each part of this part of the grading and handed them out in the instructors class on a Friday night. This was this part of the sandan grading - taken straight from Mochizuki's book.

The abovementioned JDJ ryuha does not include the taoshiwaza no kata section in their sandan grading. I would suggest that it is because the principal of that ryuha did not learn or grade this part of the grading. On the other hand, the YB sutemiwaza had been taught and trained ad nauseum within the Jan de Jong Self Defence School (JDJSDS).

A joint element of this grading is the theory behind the techniques. What is the first theory question that should be asked?

Given that the two parts are sacrifice throws and takedown techniques, the first question that should be asked is: what is the difference between a throw and a takedown?

As I discuss in my as yet unpublished book, The Science Behind All Fighting Techniques, there is no definitive distinction between throwing and takedown techniques in the martial arts literature or teachings, except the one that I provide based on biomechanics. Based on that definition and classification, about 25% of the takedown techniques in the takedown techniques section of this part of the grading are in fact throws.

There is one technique in the takedown section of this part of the grading: oshi otoshi. JDJ said that it meant 'aggressive push-down.' Every time JDJ taught it in the instructors class, he taught it differently. I was confused, not the least because none of what JDJ was teaching worked. I asked Clarke and Hymas separately, 'What are we supposed to be doing here?' They both replied that they didn't know.

At that time, the priority for JDJ and Clarke, Hymas, and Connolly was to get through the grading system so that JDJ could promote them with honorary grades. One technique that did not work - what does it matter.

Mea culpa: I too adopted the same approach as Clarke, Hymas, and Connolly, and did something in the grading, not knowing what I was supposed to be doing, knowing that it was one technique, and it would not affect my overall makes in the grading. I, like them, were going to pass this grading with or without this technique.

After JDJ passed away, and when YouTube came online, I finally saw oshi otoshi being performed by a YB school in Belgium. It is an amazing YB technique, and one which nobody in the JDJSDS has ever performed correctly, even though it is in the grading system.

JDJ did not know how to perform oshi otoshi. It looked similar to other techniques, but it wasn't that technique, and in this instance, it did not work. It was ineffective. 

A similar situation can be found in JDJ's shodan shinken shobu no kata grading with te nage. When I was taught this technique, way back when, I said even then that it did not make sense. Unbalance forward and down, and then up and back to the opposite rear corner, and then forward and down again, and then around the corner - there are so many changes in direction that you get dizzy. And why? It's because it looks like hand-set arm breaking, but that is not the takedown technique. 

When I was assisting two prospective yudansha for the abovementioned ryuha to prepare for their shinken shobu no kata grading, I again encountered JDJ's te nage and its teaching by the instructors of the ryuha. And after all these years, I still thought it was ridiculous, but this time, when searching for an answer, there are so many more resources available. JDJ's te nage should be aikido's ikkyo or nikyo. It is a great technique, when performed correctly, and one that I could perform even in my physical condition.

Part 5 Kodachi no Kata

'Demonstration of kodachi (wakizashi) techniques against katana.'

The kata is taken straight from Michael Finn's Kendo-no-Kata (1986). No deviations whatsoever, and the order is the same.







Part 6 Hojo Jutsu

'Demonstrate use of rope to tie up an opponent.'


This was an interesting grading, and an impractical grading. The techniques were taken from various sources and consisted of tying up a person in intricate ways. The impractical aspect was that the grading did not involve restraining uke before the tying up commenced. They just stood there. It was like a demonstration of wrapping a gift.

The next post will discuss the final six parts to the sandan grading.
