Overview
The Shoulder Throw family encompasses the seoi-nage (back-carrying throw) techniques and kata-guruma (shoulder wheel), which are among the most popular and effective throws in judo and grappling. [1] Shoulder throws are characterised by the thrower turning their back to the opponent and loading them onto the shoulders or upper back, then throwing them forward by pulling with the arms and bending or dropping the body. [1],[2] The seoi-nage variants — ippon seoi-nage, morote seoi-nage, eri seoi-nage, and seoi-otoshi — differ in grip configuration and body mechanics but share the fundamental principle of loading the opponent onto the back and projecting them forward. [2],[3] Kata-guruma, the shoulder wheel or fireman's carry, uses a different loading mechanism, placing the opponent across the shoulders, but shares the family's defining characteristic of using the shoulder as the primary fulcrum. [3],[4]
History & Origin
Shoulder throws have been central to judo since Jigoro Kano's founding of the Kodokan, with seoi-nage included in the original 1895 gokyo as a core technique. [1] The seoi-nage family has produced more competition victories than arguably any other group of techniques in judo history, with Olympic and World Championship data consistently showing seoi-nage variants among the top three most scored throws. [2],[3] Kata-guruma was one of the most spectacular throws in judo before the IJF's 2010 rule changes restricting leg grabs, which significantly altered its competitive application. [3],[4]

Biomechanical Mechanism
Primary Action — Pulling and lifting with the arms to load the opponent over the shoulder or upper back
Joints Involved — Attacker's shoulders (loading point), elbows (pulling action), hips (turning under the opponent)
Force Vector — Forward and downward rotation — the pulling arm creates circular momentum while the body turns underneath
Kuzushi (Off-balancing) — Forward — breaking the opponent's balance forward over their toes allows the turning entry
Position & Entry
From collar and sleeve grip — Pull the opponent forward and up, turn in while dropping below their centre of gravity, load them onto the back/shoulder and rotate forward to throw
From sleeve grip (ippon seoi) — Secure the sleeve, step across, load the arm over the shoulder while turning, pull and throw
From underhook — Turn in with the underhook side, load the opponent over the shoulder and drive forward

FIAS Combat Sambo RulesPDFTraining Notes
✓Shoulder throws (seoi nage family) are the most commonly used te waza — the opponent is loaded onto the shoulders or upper back and rotated over
✓Turn completely into the opponent so your back faces their chest — the entry must be a full 180-degree turn
✓Drop your hips well below the opponent's centre of gravity during the entry — the deeper you sit, the easier the lift
✓Pull the opponent forward and onto your back using the grips — they should feel like they are being pulled over your shoulders
✓The lifting action comes from straightening the legs after the deep entry — drive upward through the thighs and hips
✓Shoulder throws require thousands of uchikomi (fitting drills) to automate the entry
✓Seoi nage is the single most successful technique in Olympic judo history
Common Mistakes
!Not turning the hips fully — a partial turn means the opponent is beside you, not on your back
!Entry too high — your hips must be below the opponent's belt level for the throw to work
!Bending at the waist instead of sitting the hips down — this raises your centre rather than lowering it
!Not pulling the opponent onto your back with the hands — the grip pull loads them onto your frame
!Leaving space between your back and the opponent's chest — chest-to-back contact is essential
!Entering too slowly, allowing the opponent to sprawl or circle to the side
!Attempting shoulder throws without adequate grip — you need at least a collar and sleeve, or an underhook

Sub-techniques
Kata Guruma
SubFamilyKata Guruma (shoulder wheel) is a te-waza technique in which the thrower lifts the opponent across the shoulders in a fireman's carry position and then wheels them over to the mat. [1] The classical execution involves the thrower ducking under the opponent's arm, reaching between the legs to grip the inner thigh, and lifting the opponent onto the shoulders before rotating them over. [1,2] Since the IJF's 2010 rule changes prohibiting direct leg grabs in judo competition, kata-guruma has been adapted to versions that do not involve gripping the legs, using the gi or body contact to achieve the loading position.

Seoi Nage
SubFamilySeoi Nage (back-carrying throw) is one of judo's most iconic and frequently used techniques, in which the thrower turns their back to the opponent, loads them onto the upper back or shoulder, and projects them forward over the shoulder. [1] The seoi-nage family includes multiple variants distinguished by their grip configuration: ippon seoi-nage (single-arm), morote seoi-nage (two-handed lapel), eri seoi-nage (collar grip), and seoi-otoshi (the dropping version). [1,2] All variants share the fundamental mechanic of turning in, loading, and projecting, with the differences lying in how the throwing arm controls the opponent. [2,3] Statistical analyses of judo competition data consistently place seoi-nage variants among the two or three most commonly scored throws at World Championships and Olympic Games. [3]
