Обзор
Standard Sumi Otoshi executes the classical corner drop where the thrower steps to the side, pulls the opponent diagonally to the rear corner with both hands, and drops the opponent to the mat through the spiralling hand action alone. [1] No hip, leg, or body contact is used — the throw is accomplished entirely by the directional force of the gripping hands pulling the opponent into a void where no support exists. [1],[2] The technique requires the thrower to move off-line and create the corner angle while maintaining powerful pulling action. [2],[3]

Эффективность
Sumi otoshi (corner drop) is a pure hand technique that requires no leg or hip contact with the opponent, relying entirely on hand action to direct the opponent down to the corner. [1] Its effectiveness depends on precise timing and powerful kuzushi to the rear corner, making it challenging to execute but devastating when successful. [2]

Биомеханический механизм
Primary Action — Loading the opponent onto the hip and rotating them over it — the hip acts as the fulcrum
Joints Involved — Attacker's hip (fulcrum point), knees (deep bend for loading), core (rotation), opponent's centre of gravity (elevated)
Force Vector — Rotational — pulling and turning motion loads the opponent, then hip extension and rotation drives them over
Kuzushi (Off-balancing) — Forward and upward — breaking opponent's posture forward lifts their centre of gravity onto the attacker's hip
Позиция и вход
From judo grip — Break the opponent's balance forward (kuzushi), turn in with hip below their centre of gravity, and rotate to throw
From clinch (overhook or underhook) — Secure inside position, turn the hips across the opponent's body, load and throw
Варианты
Standard hip throw — full turn-in with hip below the opponent's centre of gravity
No-gi hip throw — adapted without gi grips, using overhook and collar tie
Drop hip throw — dropping to one knee to lower the fulcrum point
Combination hip throw — chaining from a failed foot technique or hand technique

✓From grips, move to one side of the opponent by stepping diagonally
✓Pull the opponent toward their rear diagonal corner — the corner behind and to one side of them
✓The pulling direction is approximately 45 degrees behind the opponent, to one side
✓Use both hands in coordination: the sleeve hand pulls sideways and back, the collar hand drives the opponent's shoulder toward the rear corner
✓Drop your own centre of gravity as you pull — step back and down to generate the direction
✓The opponent falls to their rear corner because their feet cannot reach back to support
✓Control the fall with the grips — guide them to the mat smoothly
Типичные ошибки
!Pulling in the wrong direction — the specific rear corner angle is what the throw depends on
!Not moving laterally before pulling — you must create the angle first
!Pulling upward instead of diagonally downward to the rear
!Using only one hand — sumi otoshi requires both hands working in coordination
!Standing upright during the pull — your centre must drop to generate the downward component
!Attempting from directly in front of the opponent — the corner angle requires a lateral position
!Not training the specific diagonal pulling pattern — the direction must be precise
