Judo technique

Sumi-gaeshi

Recognize instep-to-thigh contact in a rear sacrifice.

Sumi-gaeshi: Observe the instep inside the thigh and the backward roll.
Technique image: Observe the defining contact and direction in Sumi-gaeshi. The text describes a right-sided example; the opposite side mirrors it.

Understand the technique

The connection in comes from sitting close enough that the lifting instep and backward roll stay coordinated.

How it works

Establish the thigh contact

In the right example, step the left foot between Uke’s feet and connect the right instep inside Uke’s left thigh as Uke moves forward.

Roll from a close seat

Sit close to the left heel and guide Uke over the corner with the hands and lifting foot. Mirror the sides on the left; guide a roll without driving the head into the mat.

Common mistakes

Sitting too far away

A distant seat disconnects the foot from the thigh and makes the hands drag rather than guide.

First learning focus

Notice the distance between the seat and supporting heel before the backward roll.
