counter
Uchi-mata countered by Uchi-mata-sukashi
The slip: instead of blocking the throw you remove yourself from it, and your partner's own committed turn puts them on the mat. Nothing is added but timing.

Step by step
The whole sequence in words. Described in the standard right-handed form.
- Feel their leg swing between yours as they turn in for Uchi-mata.
- Do not brace against it. Turn your hips out of the way and let their lifting leg pass through empty space.
- Keep both grips and stay tall as they rotate past you.
- Guide their sleeve arm down and across in the direction they are already turning.
- Their own momentum carries them over their supporting leg with nothing to lift.
- They fall forwards onto their side; keep the sleeve so their head is supported. The whole counter is timing, not strength.
Receiving it
You are the attacker, and nothing resists you at all, which is the strange part: your lifting leg passes through empty space and your own turn keeps going with nothing to lift. You go forward, over your own supporting leg, and the fall arrives sooner than you expect because you supplied all of the power. Keep your chin tucked, stay long, and slap with your free arm as your side meets the mat.
VI judo notes
The slip is timing rather than strength, which makes it a fine counter to own without sight: their leg swinging between yours is the cue, and the answer is to turn your hips out of the way rather than to brace. Keep both grips throughout, because the grips are the only thing telling you where they are once your bodies stop touching. Guide the sleeve along the line they are already turning.
