Sumi Gaeshi (Standing)

What This Is

Sumi gaeshi — the corner throw — is a standing sacrifice throw in which the attacker deliberately falls backward to the mat while hooking and elevating the opponent’s near leg. The opponent’s loaded weight, deprived of its base, rotates forward over the attacker’s elevating leg and lands on their back as the attacker arrives in mount, rear control, or top scarf adjacent. It is one of the highest-percentage no-gi sacrifice throws because the entry is invisible until commitment and the failure mode lands in a usable bottom position rather than a back exposure.

This page covers the standing-context throw — the sacrifice throw initiated from a clinch in which both players are upright. The same name and similar mechanics also describe the seated guard sweep used to elevate a passing opponent, but the entry conditions and finish geometry differ from the standing version.

The Invariant in Action

Throw Mechanics

The Forward Kuzushi

The throw begins with a sharp forward-and-up pull on the upper body. From a body lock or over-under, the attacker pulls the opponent’s chest forward across their own centreline, loading the opponent’s weight onto the near foot. The pull direction is across-and-up, not just up — the opponent must be drawn over the line of their lead toe before the sit begins.

The Sit-Back and Hook

As the kuzushi lands, the attacker steps the entry-side foot in front of and slightly outside the opponent’s near foot, sits the hips backward, and threads the same-side shin behind the opponent’s near thigh. The shin is the elevator — it slips between the opponent’s legs at the inner-thigh height, with the foot hooking the back of the thigh just above the knee. The seat lands on the mat as the shin loads.

The Elevation

With the seat on the mat and the shin under the thigh, the attacker drives the elevating leg upward — extending at the hip and knee — while pulling down with the upper body grip. The combination of leg up and arms down rotates the opponent over the attacker. The grip must remain locked: a released grip allows the opponent’s arms to post and stop the rotation.

The Roll-Through

As the opponent rotates over, the attacker continues the motion — completing the roll so the attacker arrives on top. The roll-through is what converts the sacrifice into a dominant position; without it the attacker lands underneath the opponent and gives up the throw’s benefit. Drill the roll-through as a single continuous motion from sit to top.

No-Gi Grip Entries

Front Body Lock — Primary No-Gi Entry

The most reliable no-gi setup. From a closed front body lock, the attacker has hands clamped low on the opponent’s hips or back — the locked structure provides the upper-body pull tension that the throw needs and travels with the attacker through the sit. The locked hands cannot be shed during the elevation, which is why the body lock is the strongest configuration for the throw. See: Front Body Lock.

Over-Under Clinch

The underhook on the entry side; the overhook on the far side. The underhook lifts and pulls forward; the overhook prevents the opponent from rotating away from the throw. Less locked than the body lock but available from open clinch exchanges where the body lock has not been established. See: Over-Under Clinch.

Double Underhooks

Bilateral inside control. Both hands lifting and pulling forward provides strong forward kuzushi. The trade-off: the double underhook configuration is slightly less control than the body lock for the sit-back moment because the attacker’s hands are not joined, allowing the opponent more posture options during the elevation. See: Double Underhooks.

Post-Throw Position

The roll-through finish lands the attacker on top with several possible controls available depending on how the opponent rotated. The most common outcomes:

• Mount: When the elevation produced full rotation and the attacker’s hips ride the rotation, the finish lands in mount with the opponent flat and the attacker’s body lock or grip still engaged. The most direct conversion.
• Back control: When the opponent turns away during the rotation to avoid landing flat, the attacker arrives behind them with the body lock converting to a seatbelt. From here the back take is usually one hook insertion away.
• Top control adjacent to side control: When the rotation is partial, the attacker lands top with the opponent on their side. A short pass or knee insertion converts to side control.

The throw’s value as a no-gi entry is that all three outcomes are dominant — the failure-to-mount lands in back; the failure-to-back lands in top control. There is no failure mode that returns to neutral, which is the structural reason high-level no-gi competitors use sumi gaeshi as a primary clinch finish.

Common Errors

Drilling Notes

• Pull-and-sit timing. Cooperative partner stands in body lock posture. Attacker drills the pull-then-sit-then-elevate sequence at slow tempo, confirming each rep that the pull lands before the sit. 20 reps per side.
• Shin placement. Static elevation drill — partner standing, attacker seated with the shin already threaded under the inner thigh. Elevate without the throw motion, just to confirm the contact line. Repeat until the shin finds the correct spot automatically.
• Roll-through to mount. Drill the full sit-elevate-roll-finish to mount sequence with a cooperative partner. The roll-through is a single continuous motion — pause-points create stuck positions. 10 reps per side.
• Failure-mode drill. Practise the throw with the opponent rotating away (to back) and rotating with (to mount) so both finish lines are familiar. The body adjusts during the roll based on where the opponent goes.
