Fool Wolf: "I have recently become interested in the kihon happo. I believe Hatsumi soke took it from Gyokko ryu. The below link lists techniques called "kihon happo" to a Jujutsu school. The names for a lot of the moves are similar to the Bujinkan techniques. Is there a relationship between Gyokko ryu and the Jujutsu school mentioned? Which came first? In my current Jujutsu class I have been suprised at how many of the techniques are similar to what I have seen of Bujinkan budo taijutsu. I would be curious to hear any of your thoughts on this matter."
From what I've been able to piece together over the years, the following is what I've been able to conclude:
I don't know how many styles have a set of kata specifically called, "kihon happo," but the idea of having a group of fundamentals is common to many martial arts. The jujutsu school mentioned - after a quick glance - looks like someone took kata from Takagi Yoshin Ryu and modeled it to fit a kihon happo template, and with a few other minor tweaks, created a new style (or a new way of doing an old style).
I've only seen the kihon happo as a 'Hatsumi-ha' (Hatsumi-sensei's syle/method) of teaching basic techniques, most of which are from Gyokko Ryu. However, I don't think they were referred to as "kihon happo" within the Gyokko Ryu. The basic forms of Gyokko Ryu (before getting to the joryaku, churyaku, and geryaku no maki) consist of "ki kata" - 5 postures and their uses - likely a kind of sanshin or gogyo no kata; "moto kata" - the kihon kosshi sanpo / kosshijutsu san dan kamae kata / etc; "torite kihon kata" - the following five kata done 'sayu' (left and right) for a total of ten forms: omote kote gyaku dori, omote gyaku no tsuki ken sabaki, ura gyaku, musha dori (jigoku dori? see below *), muso dori - which were called "view one," "view two," ... "view ten;" the basics may have also included shinken taihenjutsu (muto dori).
Gary Aurther: "Today the Kihon Happo is practiced like it is laid in stone, ..."
Technopunk: "Is it?"
Yeah, I'd have to disagree too. I suppose it depends on where you train (is that how it is in Toshindo?), but the overall flavor of Bujinkan training is the exploration of many henka (variations) early on. I'm sure some/many dojo teach them as 'set in stone' for beginners to have a single fundamental form to work on before getting lost in henka land.
Gary Aurther: "...but originally it was really just an idea. When one talks for example of say Hicho Kata there is now a set way of doing this, but in the early days it simple meant 'How to use Hicho' and there were many examples. ..
I believe Kihon Happo can also be translated as something like 'Infinite ways of using the basics'"
The above is the feeling I get from watching Hatsumi (unfortunately only on video for now), and the shidoshi I train with. Each kata is an idea that leads to an infinite number of techniques.
I think that's why we see so many different outlines of the torite kihon.
The original 10 kata of the Gyokko Ryu has been modified into the Bujinkan kihon happo, and many variations exist.
r erman: "...etc, ad infinitum"
Yes, and if not to infinity, then at least to ten:
1. ura gyaku
2. hon gyaku (as ura gyaku henka)
3. omote gyaku
4. omote gyaku tsuki (as omote gyaku henka)
5. oni kudaki (omote)
6. ura oni kudaki (henka of omote oni kudaki)
7. musha dori (uchi maki dori ashi ori,
* [possibly a henka of jigoku dori, but the movements are so dissimilar, jigoku dori always seems like an 'ura' henka of the omote oni kudaki to me])
8. jigoku dori (a sort of omote henka to the 'ura' muso dori)
9. muso dori
10. ganseki nage (as muso dori henka)
Nimravus: "I guess the simplest way to summarize it all is that there is no one right way to do the kihon, but plenty of wrong ways..."
Damn that's beautiful!
Gary Aurther: "I think we are getting carried away a little bit by the names of the techniques."
Helps us to set things in stone, just the way we Westerners like it.
"The movement Musha Dori is common to lots of schools ..."
It sure is, and not just schools of the Bujinkan.
"... and is used in the Kata 'Kata Maki' from Koto Ryu, ..."
Nimravus: "The main damage point in musha dori by the way is of course the shoulder, in katamaki it's the elbow."
That's how I've seen it as well, but I have seen musha dori as a variant of katamaki.
Gary Aurther: "...in the Kata 'Oni Otoshi' from Kukishinden Ryu, and in several kata from the Takagi Yoshin Ryu. Oni Kudaki is also used in the Takagi Yoshin Ryu ..."
I'll have to check my notes to verify all that, but I believe you. I am pretty sure that oni kudaki is from TYR, but I've seen something similar in Kukishin & Shindenfudo.
"If we are saying that Mushadori comes from Gyokko Ryu, then where in the scroll is this techniques listed as being called Mushadori.
As far as I can remember there are no techniques that bear a resemblance to Musha Dori in Gyokko Ryu (although of course it depends how your insructor interprets the school)."
Interesting point. Again, I'll have to check my notes on that, but now that you mention it, I don't remember any mushadori-like movements in Gyokko Ryu kata either.
It may have been jigoku dori that was originally in Gyokko Ryu torite kihon kata, with musha dori being a variation. ??
This is all very intellectually stimulating, but of course being armed with this knowledge now, the important thing would be to practice all these variations.
