Basic or classic uchi mata?

I know a few people here have trained with Mr. Inoue. Perhaps he addressed some of these issues.

And I didn't say that things got lost in translation in his book, just that that is something to consider in your further study of his book. If you read German, I've read here that that version is the way to go.

The only other thing that interests me now is the principle of the 'hip spring'.
Like I've said in my reply to jkw I've heard and read so many different takes on this. The explanations vary from the springing motion should be in the supporting leg, in the hip, in the core, in the 'sweeping' leg, or in a combination of the aforementioned.
Any insights on what would be the correct technique?

I don't think there is any "sweeping leg" in Hane Goshi, so you can cross that one off of your list...it's not an ashi waza.

That explanation said the spring was in the leg you lift during hane goshi. Supposedly you make it 'spring' by extending that leg.

Every time I think of this throw I would recall the advice from two of our sensei here, which I paraphrase below:

1. Regarding (assuming a right-sided uchimata) where does tori's leg sweep, the inner thigh of uke's right leg? Or the left?

Hanon-sensei's answer: Neither! The leg should go right up the middle. Uchimata is not some "inside" version of harai-goshi.

2. CK-sensei's input: Tori's leg when performing uchimata does a figure-8 motion. This is something not known even by some uchimata specialists.

Hope I've contributed to the discussion.

Of course, it depends on why you mean by "understand the mechanics" of the throw too.

No, Uchi Mata is an inside forward or sideways version of Osoto Gari.

Sort of...

I can do the Nage-no-kata version of uchi-mata, but that's pretty much it. I think part of the reason I'm not good with the throw is that I don't fully understand mechanics.

I know there are people who can execute a technique effectively without understanding the principles behind it. Not me.

I'm curious - what do you mean by "inside forward or sideways version of Osoto Gari"? Where is the gari action in uchi-mata?

Kaji wrote:Yes, I do think I can manage a normal uchi-mata but not as good as I'd like to be, especially in randori.

Would you please share with me a link to that paper? Thanks.
