Arm Throw
Family手技(Te-waza)
TraditionalTranslation: hand/arm technique
Overview
The Arm Throw family encompasses te-waza techniques in which the thrower uses the arms to scoop, lift, or pull the opponent into a throw without turning the back or using hip contact as the primary fulcrum. [1] Arm throws are characterised by the direct application of hand and arm force to destabilise and project the opponent, often through scooping under the body, pulling on a corner, or creating a void into which the opponent falls. [1],[2] The three classical arm throws — sukui-nage (scoop throw), sumi-otoshi (corner drop), and uki-otoshi (floating drop) — represent different applications of arm-driven throwing mechanics. [2],[3]
History & Origin
Arm throwing techniques were recognised in the Kodokan system from its early days, with uki-otoshi included in the original gokyo as a first-set technique. [1] These techniques demonstrate judo's principle that throws can be accomplished through skilled hand control and timing without relying on body contact or leg action. [2],[3]

Biomechanical Mechanism
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
Position & Entry
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

✓Arm throws use the hands and arms to throw the opponent without major hip or shoulder contact
✓These throws lift, pull, or redirect the opponent using arm action combined with body rotation
✓Uki otoshi, sumi otoshi, and sukui nage are the primary arm throws in the Kodokan classification
✓Arm throws often use the opponent's own momentum — pulling them in the direction they are already moving
✓They require excellent timing and kuzushi rather than strength — the pull must be perfectly timed to the opponent's step or shift
✓Arm throws are valuable at longer range where hip and shoulder throws cannot reach
✓Many arm throws are performed from unusual angles, catching opponents who defend against standard hip and shoulder entries
Common Mistakes
!Trying to muscle arm throws with strength instead of timing — these are sensitivity and timing techniques
!Not creating enough kuzushi before attempting the throw — arm throws require the opponent to be off-balance
!Using arm throws at close range where hip throws would be more effective
!Not maintaining grip control throughout — arm throws depend entirely on the connection through the grips
!Pulling in the wrong direction relative to the opponent's balance — the pull must match their movement
!Attempting arm throws without sufficient randori experience to read the opponent's weight shifts
!Over-relying on arm throws, which tend to score waza-ari rather than ippon

Counter Techniques
Lower Centre of Gravity — bend knees and drop hips to make the throw harder to executeBlock the Hip — post hand on the thrower's hip to prevent loadingStep Around — circle away from the throw direction to avoid being loadedGrip Break — deny the thrower their preferred gripping configurationStiff-Arm — maintain distance with straight arms to prevent the entry
Setup Chain
1Grip Setup (Kumi-kata) — establish the controlling grips needed for the throw
2Off-Balance (Kuzushi) — break the opponent's balance in the throwing direction
3Entry (Tsukuri) — position the body for the throw by turning, stepping, or loading
4Execution (Kake) — complete the throwing action with full commitment and follow-through

Sub-techniques
Obi Otoshi
SubFamilyObi Otoshi is a judo hand technique where the attacker grabs the opponent's belt, lifts them, and drops them to the ground. [1] The attacker secures a deep grip on the opponent's belt with both hands, pulls them close, lifts them off the mat, and drops or throws them to the side. [1] It requires significant upper body strength and is classified in the Gokyo no Waza under te-waza. [1]

Sukui Nage
SubFamilySukui Nage (scoop throw) is a te-waza technique in which the thrower scoops the opponent's body upward with the arms, typically by reaching between or around the opponent's legs to lift and turn them over. [1] The scooping action can be performed from the front, side, or rear, with the thrower's arms gathering the opponent's lower body and elevating it while driving the upper body downward. [1,2] In modern judo competition since the 2010 IJF rule changes restricting direct leg grabs, sukui-nage in its traditional form is less commonly seen in shiai, but it remains an important technique in the Kodokan curriculum and in other grappling arts.

Sumi Otoshi
SubFamilySumi Otoshi (corner drop) is a te-waza technique in which the thrower pulls the opponent diagonally to the rear corner, creating a spiral off-balancing action that causes the opponent to fall toward the corner without any body contact or leg action from the thrower. [1] The throw is accomplished entirely through hand control — the tsurite lifts and turns while the hikite pulls downward toward the rear corner, creating a spiralling force that overwhelms the opponent's ability to step and recover. [1,2] Sumi-otoshi is one of judo's purest hand throws, requiring no hip, leg, or body contact to execute, making it a demonstration of the principle that skilled kuzushi alone can produce a throw. [2,3]

Uki Otoshi
SubFamilyUki Otoshi (floating drop) is a te-waza technique in which the thrower drops to one knee while pulling the opponent forward and downward, using the sudden level change and pulling action to project the opponent over and past the thrower's lowered body. [1] The throw is generated entirely by the hand action combined with the thrower's body drop — as the thrower drops, the pulling hands create a forward-and-downward force that floats the opponent over. [1,2] Uki-otoshi is the first technique in the Nage no Kata (Forms of Throwing), representing the fundamental principle of using hand control and body movement to create a throw without relying on hip or leg contact.

Morote-seoi-nage (two-arm shoulder throw) is the most common competitive variant. Toshihiko Koga's ippon-seoi-nage is considered one of the most iconic throws in judo history. (IJF records)
