Standard O Goshi
Genus大腰(O Goshi)
TraditionalTranslation: major hip throw
Overview
Standard O Goshi executes the classical major hip throw where the thrower turns in with the back to the opponent, wraps the throwing arm around the opponent's waist, loads the opponent onto the hip by pulling them forward, and rotates the hip to wheel the opponent over and onto the mat. [1] The arm around the waist provides a secure connection that prevents the opponent from separating during the throw. [1],[2] The throw is completed by a combination of hip rotation, pulling arm action, and forward bending that projects the opponent over the hip. [2],[3]
History & Origin
Effectiveness
O goshi is one of the most straightforward and reliable throws in judo, effective for beginners and experts alike due to its simple mechanics — the arm around the waist provides a secure connection that makes it difficult for the opponent to escape once loaded onto the hip. [1] While experienced competitors can defend against it more easily than some other hip throws, its mechanical simplicity makes it one of the most consistently executable techniques. [2]
Lineage
O goshi was included in the original 1895 Kodokan gokyo no waza as a first-set technique and has been taught as one of the foundational throws in the Kodokan curriculum since. [1] Jigoro Kano personally demonstrated o goshi in his teaching, considering it the fundamental hip throw from which all others derive. [2]
Competition Record
The standard o goshi is scored at all levels of judo competition. [1]

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 standard judo grip (collar and sleeve) — Pull opponent forward and off-balance (kuzushi), turn in with back to opponent, load their weight onto your hip, extend legs and rotate to throw
From overhook (no-gi) — Secure an overhook and collar tie, turn in placing hip across opponent's centreline, and execute the hip throw
Variants
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

FIAS Combat Sambo RulesPDFTraining Notes
✓Step deep across uke's centre with the lead foot, placing it between or just past uke's feet
✓Pull uke's sleeve hand sharply forward-and-down to break their balance (kuzushi) before turning in
✓Wrap the throwing arm tightly around uke's waist — your forearm should press firmly against their lower back
✓Bend both knees so your hip makes contact below uke's belt line
✓Lift by straightening the legs while simultaneously pulling the sleeve hand in a circular arc over your shoulder
✓Follow through by continuing the rotation — your chest should face the mat at completion
✓Drill against a crash pad first to build confidence in committing to the full rotation
Common Mistakes
!Entering with the feet too close together, reducing your base and making you unstable
!Not pulling uke forward before turning in — if they're upright, the throw requires excessive force
!Wrapping the arm loosely so uke can create space and block the hip
!Lifting with the back instead of the legs — this is the primary cause of lower-back injury in hip throws
!Stopping the rotation at 90° instead of completing to 180°
!Not keeping the chin tucked during execution — looking up destabilises your posture
!Forgetting to maintain sleeve tension throughout the entire throw

Frequently Asked Questions
Should I try to lift my opponent up and over in o goshi, or is there a better approach?
Rather than lifting them up and over, focus on turning their body instead. Riki Judo Dojo emphasizes that this rotational approach reduces strain on your shoulder and is far more effective than pure lifting mechanics.
What's the correct body positioning when entering o goshi?
You must always position yourself below your opponent's center of gravity, below the komamusubi. Riki Judo Dojo stresses that you should turn your head to make a circular movement rather than looking at your partner, and step across their big toe line as you turn in.
How should I grip and position my hands for o goshi?
Keep your hand open rather than closed, using your fingertips to bend in and secure a tight grip around your opponent's waist. Riki Judo Dojo explains that you should lean in the direction you want to throw and bring your elbow in as you use your turn to complete the technique.
How important is shoulder rotation in executing o goshi?
Shoulder rotation is critical—Riki Judo Dojo describes the shoulder strike (katazuki) as a powerful turning motion that allows you to get your hips over for the throw. Without proper shoulder turn, you won't generate the necessary power to complete the technique successfully.
