Why everyone forgets Jigoro Kano's own work "Kodokan Judo" I'll never understand. In it he clearly lays out that uchi-mata is a technique that is applied as weight is transferred to the leg that is being reaped. The "modern" hane-uchi goshi mata throw is, in my view, a result of the way people train nowadays; death by static uchikomi. This made it difficult to apply uchi-mata properly. Because there is no movement in static uchikomi, whenever people entered for uchi-mata they unweighted the leg they were trying to attack making the technique ineffective. This is exacerbated by the use of the collar grip; tori shoves their elbow into uke's armpit to get them to turn more. The only solution to this problem is to attack the leg that is now weighted. Thus you get this mangled hane-goshi uchi-mata hybrid. It's a technique born of a misunderstanding of what uchi-mata is, compounded by the mistaken belief that tory is trying to turn uke as they lift. Kano's own work clearly states that uchi-mata happens in two stages; first the reaping leg lifts uke and then the arms rotate uke over. All of this is laid out in the Nage no Kata, which preserves the ideal situation to apply the various techniques found within it.

Great analysis. I've seen way too many "uchi-mata tutorials" teaching heavy hip involvement in lifting. It's classified as an ashi-waza for a reason.

As I have not practiced Judo for many years (I am past eighty) it is interesting to see the developments that have accumulated since the 1960's. I numbered uchimata among my useful throws and we concentrated on timing the entry for the attack for right side uchi mata with a side ways /leftward step of the opponent. I like the idea of the outward step. This is using bodyweight like the "drop step" taught by some for atemi and will surely add to the kinetic energy in the kake portion of the throw. I really enjoy your videos!

[haffoc]

one of your better videos. thanks for the analysis.

[caud]

Love your detail explanation. Best Judo channel

[solagratia]

This is very stimulating and in-depth exploration of uchi mata, thank-you Chadi for your enthusiasm and keen interest in sharing this

[mojidoza]

Great analysis! It helps me to understand the detail of Uchi Mata.

I believe that this combinatorial explosion of subtle variation is what happens when we concentrate on the possible mechanics of tori, rather than the minimum required mechanics/or manipulation tori's body by uke - and here of course there are many different ways to achieve (and even overshoot) the minimum required manipulation of tori's body.

As a judoka I have watched many judo instructional videos in the past... but made my biggest and fastest jump after watching and studying John Danaher's standing instructional videos... his style was completely different from what was taught in my dojos and what I had seen in other instructional videos. He opened my eyes to how to understand throws (even other throws that he did not discuss), he puts a lot of emphasis on understanding the minimum required mechanics that tori has to put in (and high percentage variations instead of holding on to tradition)... once I understood that, I found myself throwing people even with moves that I was creatively coming up with on the spot... because I had a clear sense of direction.

awesome thanks for pointing out this detail

[furiousfellow]

been watching maruyama videos for years, now I see them with different perspective, thanks for the beakdown!!

[Ramboldt]

I never understood why it was like that in the kata, so this video was quite helpful!

[joatanpereira]

It's just like tai-otoshi and tani-otoshi: in tai-otoshi people use their hips and legs, instead of their arms, it's a te-waza; in tani-otoshi, they use their leg, when there should be no involvement.

[davidwallace]

very eye opening, I never saw it like this, thanks!

[TonyPacenski]

In the fluid Judo example, this is a type of balance breaking and hand presentation I have more success with against either left or right Judokas in randori in the Dojo. I like to have more momentum and ideally have uke on one leg.

[BigUriel]

I have to correct you there, uchi mata is not loved by everyone. It is my nemesis.

[BlEAKIN]

Just like every other throw, Uchimata has evolved in a way so that it works in practice against a resisting opponent. I don't understand why multiple channels continue to analyze techniques in a vacuum and looking at demonstrations from Kodokan. Even Japanese competitors don't do that.
What makes Uchimata happen is pretty much what makes every other forward throw happen - using YOUR BODYWEIGHT and MOVEMENT to get your opponent out of balance. To create instability in your opponent and break their balance, you must first create momentary instability in yourself as well.
For Uchimata, you attach your opponent to yourself by pulling them in, then lean back and down while reaping their leg up, which spreads their hips and makes their supporting leg lose contact with the ground, unless:
1. They are very flexible and you did not actually properly attach them to you.
2. They are taller than you (usually)
You see these fundamental concepts in any variation of Uchimata you can find. Whether uke lands a bit higher on the hip, or you reap their leg really low, is not of too much importance - if you have not broken their balance using your bodyweight, the throw is not gonna happen.
Chadi, please just watch Korean judokas tutorials and learn how to actually perform throws. After all this time you still do not understand the fundamental concepts of balance, movement and judo in general. For some reason you are also very unathletic, your legs are straight and stiff as sticks. You need to bend your knees in all movements if you want to have any sort of impact. I don't even know how to formulate this, you just move extremely awkwardly and stiff.

Every time I see a new video on this channel, I think “oh! What goodies does he surprise us with today!!?”

[sushinfudoshin]

Any involvement of the hip during the throw would make the throw to be considered as Hane goshi ?
I beg to defer, solely on the etymology of "hane goshi", coming from the root word "hane", indicating a whiplash of the (entire) leg.
In his book, Hitoshi Sugai gave a very detailed list of the different variations.

I agree that this throw has evolved tremendously over time, and we mostly see the same types on the IJF circuit.

Bonne vidéo, tu t'entraînes à Brétigny ?
