腰車(Koshi Guruma)

Traditional

Translation: hip wheel

Overview

Koshi Guruma (hip wheel) is a koshi-waza technique in which the thrower turns in, wraps one arm around the opponent's neck or head, and uses the hip as a fulcrum to wheel the opponent over in a forward rotation. ^[1] The arm around the neck distinguishes koshi-guruma from o-goshi (arm around the waist), and this higher control point gives the thrower leverage over the opponent's head and posture. ^[1],[2] The neck control forces the opponent to bend forward and over the hip, creating a powerful wheeling action that is difficult to resist once the entry is secured. ^[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

Training Notes

✓Koshi guruma (hip wheel) wraps the arm around uke's neck/head rather than the waist — this creates a longer lever for rotation (Daigo, Kodokan Judo Throwing Techniques, 2005)

✓Enter deeply as with o goshi but wrap your arm over uke's far shoulder and around the back of their neck

✓The neck wrap prevents uke from posturing up or pulling away during the throw

✓Drive the throw with hip rotation and leg straightening — the headlock grip is for control, not choking

✓Koshi guruma is effective against taller opponents because the neck wrap brings their upper body down

✓In no-gi grappling, this throw translates directly as a headlock hip throw

✓Practise with controlled neck pressure — excessive cranking is dangerous and will injure training partners

Common Mistakes

!Cranking the neck aggressively — koshi guruma is a throw, not a neck crank; the arm guides, it doesn't squeeze

!Entering too shallowly so the arm reaches the neck but the hip isn't loaded — uke won't go over

!Not bending the knees enough during entry — koshi guruma requires getting very low because you're controlling the head

!Pulling uke's head down without rotating the hips — this just bends them over without throwing

!Wrapping the arm around the throat instead of the back of the neck — this becomes a choke and is illegal in judo competition

!Standing on tiptoes during the throw — stay grounded through the feet for power

!Not drilling breakfalls — koshi guruma drops uke fast and hard

Related Techniques

Major Hip Throw — shares hip-loading mechanics and similar kuzushi principles Breakfall (Ukemi) — essential receiving skill for safe practice of this throw

Counter Techniques

Lower Centre of Gravity — bend knees and drop hips to make the throw harder to execute Block the Hip — post hand on the thrower's hip to prevent loading Step Around — circle away from the throw direction to avoid being loaded Grip Break — deny the thrower their preferred gripping configuration Stiff-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

Standard Koshi Guruma

Genus

Standard Koshi Guruma executes the classical hip wheel where the thrower turns in, wraps the throwing arm around the opponent's neck, loads the opponent onto the hip, and rotates forward to wheel the opponent over the hip and to the mat. [1] The neck grip controls the opponent's head throughout the throw, preventing them from posturing up and escaping. [1,2] The throwing motion combines hip rotation with the arm pulling the opponent's head and upper body forward and over the fulcrum point of the hip. [2,3]

Notes

Koshi guruma (hip wheel) appears in 6 books in our corpus. It wraps the arm around the opponent's neck rather than under the arm — distinguishing it from o-goshi. One of the original forty throws of the Kodokan gokyo. (Kano, Kodokan Judo; KyokushinBudoKai Beginners Guide)

Frequently Asked Questions

How is Koshi Guruma different from O Goshi?

Koshi Guruma is very similar to O Goshi, but instead of grabbing around the waist, you grab around the neck and shoulder area. Like O Goshi, you're lifting your opponent up and over your hip rather than pulling them down into you.

Which hand is more important in Koshi Guruma—the hand around the neck or the other hand?

According to Welcome Mat Steve Scott, most people focus too much on the hand around the neck, but the pulling hand (hiki te) is actually the most important. The pulling hand lifts and traps your opponent, while the hand around the neck mainly locks them to your body.

Should I pull my opponent down into me when executing Koshi Guruma?

No—avoid pulling your opponent down into you, as this is a common mistake. Instead, focus on lifting them up and over your hip, just as you would with O Goshi.
