Overview
The Inner Thigh Throw family centres on uchi-mata, one of the most celebrated and effective throws in all of judo, in which the thrower drives the back of the thigh or leg upward between the opponent's legs to lift and rotate them over. [1] Uchi-mata techniques combine elements of hip throws and leg techniques, with the sweeping inner thigh action acting as the primary lifting mechanism while the upper body rotation completes the throw. [1],[2] The family includes the classical uchi-mata and its variants — ashi (leg-style), ken-ken (hopping), and counter applications — each adapting the core inner-thigh sweeping principle to different tactical situations and body types. [2],[3] Uchi-mata has been statistically the single most scored throw in international judo competition across multiple decades, reflecting its effectiveness and versatility. [3],[4]
History & Origin
Uchi-mata was included in the Kodokan gokyo from its earliest iterations and has grown to become the signature throw of modern judo. [1] The technique was notably developed and popularised by many of judo's greatest competitors, including Yasuhiro Yamashita, who used uchi-mata as his primary technique en route to Olympic gold in 1984 and an undefeated record of 203 consecutive victories. [2],[3] Kosei Inoue further elevated uchi-mata's profile with his devastating execution at the 2000 Sydney Olympics. [3],[4]

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

✓Uchi mata (inner thigh throw) lifts the opponent's inner thigh with your leg while rotating them over your hip and leg
✓It is one of the highest-scoring throws in international judo competition and a favourite of many Olympic champions
✓The throw combines a hip throw entry with a sweeping leg action against the inner thigh
✓Turn into the opponent as if entering a hip throw, then swing your leg between their legs and upward against the inner thigh
✓The throwing leg sweeps upward against the inner thigh while the hands pull the opponent forward and over
✓Uchi mata requires full commitment — the body rotation and leg sweep must work together explosively
✓Practise the leg sweep motion separately (one-legged sweeping drill) before combining it with the full body entry
Common Mistakes
!Not turning the hips fully into the opponent — uchi mata requires a complete hip entry, similar to a hip throw
!Sweeping the outside of the leg instead of the inner thigh — the sweep must go between the legs
!Not pulling the opponent forward and over with the hands — the hands are as important as the leg sweep
!Attempting uchi mata from too far away — you must be at hip-throw distance with chest contact
!Sweeping too low (at the ankle) instead of targeting the inner thigh area
!Bending at the waist instead of rotating through the hips
!Losing balance on the standing leg — uchi mata is a one-legged throw, so the standing leg must be rock-solid

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
Uchi Mata
SubFamilyUchi Mata (inner thigh throw) is a judo technique classified as ashi-waza in which the thrower turns in, lifts the attacking leg between the opponent's thighs, and sweeps upward with the back of the thigh while rotating the upper body to throw the opponent over the hip. [1] The throw combines rotation, lifting, and sweeping into a single explosive action, with the thrower typically entering on one foot and driving the sweeping leg upward to lever the opponent off the ground. [1,2] Uchi-mata exists on a spectrum between a hip throw and a leg throw depending on the practitioner's body type and preferred entry, with taller fighters tending toward a leg-dominant (ashi) version and shorter fighters using more hip rotation.

Uchi Mata Counter
SubFamilyThe Uchi Mata Counter subfamily covers techniques specifically designed to defeat an incoming uchi-mata attack, using the opponent's turning and lifting momentum against them. [1] Because uchi-mata requires the thrower to turn their back and commit to a one-legged stance, it creates specific vulnerabilities that can be exploited by an alert defender. [1,2] Common counter methods include blocking the sweeping leg and redirecting the rotation, stepping over the attacking leg, or simply resisting and rolling the attacker over from their compromised position.

Notes
Uchi-mata is statistically the highest-scoring throw in Olympic judo history. It was the tokui-waza (favorite technique) of multiple Olympic champions including Kosei Inoue and Tadahiro Nomura. (IJF competition data; Kodokan records)
Frequently Asked Questions
Is the inner thigh throw more of a hip technique or a leg technique?
According to MRAKRON, it functions as a hip technique rather than purely a leg throw, with flexibility being particularly important for executing it effectively.
What's the key body positioning I should maintain during an inner thigh throw?
MRAKRON emphasizes keeping your head above your opponent's head at all times, following basic wrestling principles, and avoiding leaning away from your opponent during the technique.
How should I move into position for the inner thigh throw?
MRAKRON describes a three-part sequence: pop, circle, and pull—you turn away from your opponent while simultaneously getting closer to them, then hop and lift your leg like a pendulum motion to execute the throw.
