Hip Technique Throw — Koshi Waza

Group

腰技(Koshi-waza)

Traditional

Translation: hip technique

Overview

The Hip Technique Throw group, known in Japanese as koshi-waza, comprises all throwing techniques in which the thrower's hip serves as the primary fulcrum or lifting mechanism, rotating or wheeling the opponent over the hip to project them to the mat. [1] Koshi-waza techniques are among the most intuitive and powerful throws in grappling, using the hip as a lever point placed beneath the opponent's centre of gravity to generate mechanical advantage. [1],[2] The group includes major hip throws (o-goshi, uki-goshi, koshi-guruma), sweeping hip throws (harai-goshi, hane-goshi), spring hip throws (tsuri-goshi), and hip wheel techniques (ushiro-goshi), each employing the hip fulcrum in different ways. [2],[3] Hip throws are often the first techniques taught to judo beginners because they clearly demonstrate the fundamental principle of getting underneath the opponent's centre of gravity and using the body as a lever. [3],[4] In competition, koshi-waza techniques — particularly harai-goshi — rank among the highest-scoring throws and are effective across all weight categories. [4],[5]

History & Origin

Hip throwing techniques are among the oldest documented grappling methods, with hip throws depicted in ancient wrestling art from Egypt, Greece, and throughout Asia. [1] In judo, koshi-waza was one of the original three groups in Jigoro Kano's nage-waza classification, and several hip throws were included in the first gokyo no waza of 1895. [1],[2] O-goshi and uki-goshi were among the foundational techniques of early Kodokan judo, with Kano reportedly developing uki-goshi as one of his personal favourite throws during the formative years of judo. [2],[3] The hip throw family has remained central to judo pedagogy for over 140 years, and hip throwing principles are shared across wrestling, sambo, aikido, and virtually every grappling tradition worldwide. [3],[4]

Effectiveness

Koshi-waza (hip techniques) use the attacker's hips as a fulcrum to load and rotate the opponent over. [1] Hip throws are among the most powerful throwing techniques due to the large muscle groups involved. [1],[2]

Lineage

Jigoro Kano classified koshi-waza as one of the five categories of nage-waza in the Kodokan judo syllabus. [1] Hip throws also feature prominently in Greco-Roman wrestling, sambo, and traditional folk wrestling. [2]

Competition Record

Hip throws, particularly harai goshi, are among the highest-scoring techniques in IJF competition. [1]

Biomechanical Mechanism

Primary ActionLoading the opponent onto the hip and rotating them over it — the hip acts as the fulcrum
Joints InvolvedAttacker's hip (fulcrum point), knees (deep bend for loading), core (rotation), opponent's centre of gravity (elevated)
Force VectorRotational — 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 gripBreak 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 waza use the hip as a fulcrum — the opponent is loaded onto your hip and rotated over it
The key principle: your hip must be lower than the opponent's centre of gravity and turned into their body
Pull the opponent onto your hip with the upper body while your hip acts as the pivot point
Entry requires a deep step and full hip rotation — turn your back completely to the opponent and load them onto your hip
Hip throws work best against forward-pressing opponents — use their momentum to pull them over your hip
O goshi is the fundamental koshi waza — master it before progressing to more complex hip variations
Mifune in Canon of Judo described the hip throw as the epitome of using the opponent's force against them

Common Mistakes

!Not getting the hip low enough — if your hip is at the same height or higher than theirs, you cannot load them over it
!Failing to turn completely into the opponent — partial turns leave you exposed to counters
!Bending forward at the waist instead of sitting the hips down and back — you pull yourself down rather than throwing them
!Not maintaining chest-to-chest contact during the loading phase — any gap lets the opponent posture up and resist
!Trying to lift with the arms instead of using the hip as the fulcrum — hip throws are leverage techniques, not strength techniques
!Entering from too far away so the hip never makes contact with the opponent's body
!Stopping mid-rotation instead of completing the full turning motion through the throw

Sub-techniques

Hip Wheel

Family

The Hip Wheel family covers koshi-waza techniques in which the thrower uses the hip as a pivot point to wheel the opponent over in a reverse direction, countering the opponent's forward attack by redirecting them over the thrower's hip from behind. [1] Hip wheel techniques differ from standard hip throws in that they often involve the thrower intercepting the opponent mid-throw and redirecting the momentum over the hip in a counter-throwing action. [1,2] Ushiro-goshi, the primary technique in this family, is a powerful counter-throw that lifts the opponent from behind and wheels them over the hip. [2,3]

Major Hip Throw

Family

The Major Hip Throw family covers the foundational koshi-waza techniques in which the thrower turns in, places the hip beneath the opponent's centre of gravity, and wheels the opponent over the hip using arm action and hip rotation. [1] This family includes judo's most fundamental hip throws: o-goshi (major hip throw), uki-goshi (floating hip throw), and koshi-guruma (hip wheel), each representing a different variation of the core hip-loading-and-wheeling principle. [1,2] These techniques are typically the first koshi-waza taught to beginners because they demonstrate the essential mechanics of hip throwing — turning, loading, and projecting — in their clearest form. [2,3]

3 subfamilies·6 techniquesExplore

Spring Hip Throw

Family

The Spring Hip Throw family covers koshi-waza techniques in which the thrower uses a lifting or springing hip action to elevate the opponent off the ground before throwing them, rather than simply wheeling them over the hip. [1] Spring hip throws are characterised by an upward lifting component generated by the hip and legs, which elevates the opponent's centre of gravity before the rotational throwing action. [1,2] Tsuri-goshi, the principal technique in this family, uses a belt or back grip to lift the opponent onto the hip before projecting them forward. [2,3]

1 subfamilies·2 techniquesExplore

Sweeping Hip Throw

Family

The Sweeping Hip Throw family covers koshi-waza techniques that combine the hip fulcrum with an active sweeping action of the leg, creating throws that merge hip-throwing and leg-sweeping mechanics into a single powerful action. [1] Sweeping hip throws use the hip as a fulcrum while the attacking leg sweeps, springs, or drives against the opponent's leg, adding rotational or lifting force that amplifies the throwing action beyond what the hip alone would produce. [1,2] The two principal sweeping hip throws — harai-goshi (sweeping hip) and hane-goshi (spring hip) — are among the most powerful and frequently scored throws in judo competition. [2,3]

Notes

Koshi waza (hip techniques) use the hip as a fulcrum to throw the opponent — o-goshi, harai-goshi, uchi-mata. Jigoro Kano's personal favorites were hip throws. Uchi-mata is statistically the highest-scoring throw in Olympic judo history. (Kano, Kodokan Judo; IJF competition data; Watson, Judo Memoirs of Jigoro Kano)

Frequently Asked Questions

What's the key hand motion when executing a hip throw?

According to The Judo Way of Life, you punch through with your grip as you come around, then pull down with your other hand to create a reaction, and catch your opponent's head as they come up to complete the throw.

When should I time my hip throw entry?

The Judo Way of Life emphasizes that the hip throw works effectively either when your opponent reacts to your initial pull and comes up, or after you've created tension—timing your step through as they move is very important.

What's the most important thing to do if someone is already throwing me with a hip throw?

Seiryoku Zenyo notes that if you're already in the air during a hip throw, Yoko Garuma (the side wheel) is the throw of last resort—you want to lift your hip off the ground at the end while maintaining your grip with one hand pulling in and the other lifting up.

How do I defend against a hip throw attempt?

Seiryoku Zenyo teaches that as your opponent comes in, move your hips out to the side, drop your level, pull them in, and get them up on your hip, then turn and lift to bring them in front of you—this counter is called Utsuri Goshi (shifting hip throw).
