Sumi Gaeshi, the corner reversal throw, is a rear sacrifice technique in which tori drops underneath uke while hooking the inside of uke's thigh with one leg and rolling backward to sweep uke over. [1] The throw works by disrupting uke's balance to the rear corner (sumi) while tori's body acts as a fulcrum, creating a wheeling action that carries uke overhead. [1],[2] Sumi gaeshi is one of the original forty throws of the Kodokan gokyo and is classified as a ma sutemi waza (rear sacrifice technique). [2],[3] The technique is especially effective against opponents who adopt a defensive, bent-over posture, as their lowered centre of gravity can be exploited by the rolling action. [3]
История и происхождение
Sumi gaeshi was included in the Kodokan gokyo from its earliest formulations, reflecting its importance in classical judo training. [1] The technique derives from older jujutsu methods of using an opponent's forward pressure against them. [1],[2] Modern competitors frequently use butterfly guard entries from BJJ as adaptations of the sumi gaeshi principle. [2],[3]

Биомеханический механизм
Primary Action — Sweeping, reaping, or blocking the opponent's foot or leg to remove their base of support
Joints Involved — Attacker's sweeping leg (ankle or shin contact), opponent's supporting ankle or knee (swept)
Force Vector — Two opposing forces — the upper body is directed one way while the sweeping leg removes the support in the opposite direction
Timing Principle — Maximum effectiveness when the opponent's weight is committed to the targeted foot — timing supersedes strength
Позиция и вход
From judo grip — Use push-pull timing (kuzushi) to catch the opponent as they step, sweep the support foot in the direction of their movement
From clinch (collar tie) — Push or pull to make the opponent step, sweep the stepping foot at the exact moment it lifts off the mat

✓Sumi gaeshi (corner reversal) uses a butterfly hook (foot on uke's inner thigh) to throw them diagonally over your shoulder (Mifune, Canon of Judo, 1956)
✓Hook your instep inside uke's near thigh — this is the fulcrum that elevates their lower body
✓Pull uke forward and to the side as you fall back — the diagonal direction distinguishes sumi gaeshi from tomoe nage
✓The throw direction is over your shoulder, not directly overhead
✓In BJJ, sumi gaeshi is one of the most effective sweeps from butterfly guard — the mechanics are identical
✓Grip deep on uke's belt or around their back for maximum control during the roll
✓Sumi gaeshi is excellent when uke leans forward with a wide base — hook and roll
Типичные ошибки
!Hooking too deep (behind the knee) instead of on the inner thigh — reduces the lifting action
!Throwing directly overhead like tomoe nage instead of diagonally — different throw, different direction
!Not pulling uke's upper body to the side with the grips — the diagonal pull is what makes sumi gaeshi work
!Falling straight back instead of at an angle — the diagonal fall matches the diagonal throw
!Releasing the grips too early — maintain control through the landing
!Not elevating with the butterfly hook — the leg must actively lift, not just block
!Attempting without uke's weight committed forward — sumi gaeshi needs forward pressure to redirect

Часто задаваемые вопросы
What grip should I use when setting up sumi gaeshi?
According to Welcome Mat Steve Scott, you want to secure a solid back grip on your opponent's middle back between the shoulder blades. When reaching around, use your thumb position and apply tension with the inside of your elbow against the opponent's deltoid rather than just reaching over the top.
How should I position my feet when executing sumi gaeshi?
Welcome Mat Steve Scott emphasizes standing with your toes pointing in the direction you're moving—your left foot steps in while your right foot jams as you roll back. Standing sideways is weak positioning and won't give you a strong base for the throw.
Is sumi gaeshi a good throw for taller people?
Welcome Mat Steve Scott notes that sumi gaeshi is considered a tall person's sacrifice throw, making it a good alternative to circle throws for taller practitioners or those of similar height to their opponent.
What setup techniques work well before attempting sumi gaeshi?
Shintaro Higashi recommends attacking your opponent's front leg with an ochi grip first to force their leg away and adjust their stance, which sets up the conditions for a successful sumi gaeshi entry. He also emphasizes establishing good head position and a two-on-one grip before executing the throw.
