Hi
Do many of the Judokas here cross-train with Japanese Jiu jitsu? and how effective do you view the self-defence applications of its techniques and training methods?
Not so many, I reckon, but I do.
For background, note that there are surprisingly few active schools of 'jujutsu' in Japan; the ‘jujutsu’ term is more widely used overseas for some interesting (to martial arts historians) and not so interesting (e.g., homegrown ‘goshinjutsu’ styles) reasons. In fact, AFAIK most Japanese who don't practice martial arts don't even know the word jujutsu, while even those that do practice might explain it as ‘old style judo’. But that’s not necessarily unique to Japan; in Europe, AFAIK, most judoka don’t crosstrain in jujutsu or other styles.
In the earl 1900’s, before judo spread overseas and before it was fully established and ascendant in Japan, several Japanese traveled overseas and taught a number of jujutsu styles. A handful of Westerners in Meiji Japan and overseas studied jujutsu from Japanese and took portions of their training to the West; one of the more interesting examples was the English engineer E.W. Barton-Wright, who traveled around Japan working in the effort to establish the first Japanese rail systems. He probably studied at least a couple of different styles of jujutsu in different cities around Japan, and upon his return to London recruited a couple of young Japanese to come as instructors, and established a dojo to teach his 'Bartitsu' style synthesized from his experience. (It is the famous 'Baritsu' mentioned by Sherlock Holmes.) See
http://www.geocities.com/lone_wolf_92001/Index.html and the Bartitsu Forum at
http://groups.yahoo.com/group/Bartitsu_Forum/ for some of the details unearthed by the Bartitsu Society, a group of enthusiasts and researchers.
For me the notable jujutsu schools in Japan (outside of BJJ, of which I know nothing except there are some dojo in Tokyo) are koryu styles, of which CK mentions several. I know Japanese and Western judoka who now explore koryu jujutsu styles, drawn for a variety of reasons, including interest in the history, heritage, self defense techniques, the search for novelty, whatever. Some of these judoka studied judo only in high school and college, stopped afterwards, and now are interested non-competitive, more traditional martial arts, but often have a solid foundation in judo. (There are untold numbers of aikido offshoots that incorporate tons of jujutsu technique, but they call themselves something else, and typically draw their lineage from one of more of the aikido legacies.)
There are also at least a handful of modern jujutsu styles in Japan. Some draw lineages from various koryu or are based on the pre-war, pre-aikido aikibudo of Ueshiba sensei (I’ve studied one of these for years). Others such as Sato Kinbei sensei’s Daiwado ryu jujutsu are modern styles drawn from a number of older styles. I’m not sure but might try to put that Mochizuki sensei’s Seibukan jujutsu in that category, since he studied prewar aikibudo under Ueshiba and prewar judo. Others attempted this; witness Rokugo ryu jujutsu (based in Tokyo, it collected techniques from six different koryu jujutsu schools) and Higo ryu taijutsu (also a synthesis of techniques from 6 schools from the city of Kumamoto, previously known as Higo), styles seemingly developed as counters to the growing popularity and central government recognition and support of Kodokan judo; most failed and seem defunct.
CK notes some koryu styles, while there are others still active around Japan with some number of active dojos: these include Daito ryu, Takeuchi ryu, Araki ryu, Yagyu Shingan ryu, etc. Others are essentially seem to be limited to a single active dojo with only a very small numbers of practitioners, such as Shosho ryu, Shibukawa ryu, Ishiguro ryu, and others.
I'm sure there are some individuals that cross train judo, but don't know if they're on the forum; I don’t know many of them that hang out on English websites. You might find more that cross train in judo and aikido, a much more common art in Japan.
Almost without exception those koryu jujutsu I’ve named (the exception I don't know anything about personally is Kito ryu, reportedly one of the more esoteric schools, but have seen most of the others, practiced a couple briefly and informally w/ qualified friends, and practice one regularly myself) even if called 'jujutsu', can generally be classified as sogo bujutsu, or ‘general martial arts’ if you would. That is, they use a range of weapons and techniques, including bo, jo, hanbo, bokken, naginata, spear, iaito, etc., in addition to unarmed grappling and techniques for use in situations against an opponent armed with a range of weapons, along dissimilar weapons kata (e.g., jo against sword, sword against naginata or spear). And even some koryu kenjutsu styles still maintain grappling techniques, too, although many seem lost to time.
Focusing on the grappling portions (which go by a variety of traditional names), I am in no way an expert in of the ancient arts, but my impressions, clearly generalizations, and without violating various traditional confidentialities, are as follows:
- Some jujutsu styles have tremendous self defense techniques and kata (bearing in mind that the training style almost invariably kata).
- With the variety of weapons of a variety of lengths, my sense of ma-ai (interval) has perhaps been stressed (enhanced?) more than it would be otherwise. A large range of weapons, from empty hand to long spear, made me, at least, more me aware of intervals.
- Some of the throws could be lethal, and many joint locks or throws could easily break or dislocate joints. These can be hard or impossible to practice realistically at full speed / force without damaging uke. So how do you know they’d really work, or how well? Some seem hard to tell.
- Some kata such as strikes to eyes or throat can’t be practiced (at least not in most traditional styles; some guys will don karate protective gear and go at it, but they’re really different gents, not your normal practitioners).
- Some of the assumptions behind certain kata are not pertinent to the modern world (e.g., you’re wearing armor, two swords stuck in your obi, the hilts of which can be deadly obstacles to you or impromptu weapons themselves, you’ve lost the blade of your spear, now you’re carrying a long bo, maybe in a narrow alley, you’re in a space with a very low ceiling and have to draw a sword or defend against one) but make sense in the context of pre-Meiji Japan (which is the definition of koryu, a pre-1867 style). But that’s the kata, it’s not meant to be updated for the modern world. A friend calls them the ‘Model A’s of martial arts techniques’; some people like to collect old, barely functional cars, while others think it’s a waste of time. But since these, too, are part of the syllabus, you don’t get to pick and choose, so a significant amount of your time can be spent on techniques that seem less than useful in self defense.
- Many moves seem unenlightened by kuzushi, or the kuzushi that is introduced comes from a preliminary strike or shove before the throw or joint lock. This can be very hard to practice realistically.
- The movements can be very strong, but often use power and leverage to overcome an opponent rather than kuzushi.
- Many of the kata seem very linear to me. To perform correctly some per certain kata, you have to move a significant distance back or forward, which may be fine if you’re in one-on-one combat and someone is guarding your back. But if your back is to a wall, perhaps you can’t move back. What then?
- Some of the koryu kata are simply nasty, direct. Slashes to the femoral artery to bleed out an opponent, slowing them down for the kill. Hand to gland. Leg hocks (osoto gake) with the opponent’s head forced back so that the skull impacts first, no chance for ukemi. Offbalancing forward then a knee to the face / elbow to the base of the skull. A big overhead throw with a kick to the base of the skull on the way down. Not nice. Of course, you’ve got to get your opponent in that bad position first, and judo is superb at training that.
None of this is surprising from a judo standpoint, I’d guess, given the effort to weed out the most dangerous techniques and make the modern jujutsu that became judo safe for practice.
There is plenty of raw material for the study of jujtsu in the judo kata; many major techniques are there, they just need to be pulled out and practiced safely. Viola’ – instant jujutsu syllabus.
