Uchi Mata
SubFamily内股(Uchi Mata)
TraditionalTranslation: inner thigh throw
Overview
Uchi 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. [2],[3]
History & Origin
Uchi-mata has been a core Kodokan technique since the original gokyo, listed in the third set as an advanced throw requiring coordination of turning, lifting, and sweeping. [1] It rose to prominence in the mid-20th century as judo competition evolved, and by the 1970s had become the single most commonly scored throw at the highest levels of international competition.

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

✓Enter as if performing a hip throw — turn your back to the opponent with grips secured
✓Swing your dominant leg between the opponent's legs, sweeping upward against the inner thigh of their far leg
✓Pull the opponent forward and over your body with strong hand action while the leg sweeps them off the ground
✓The leg action and the hand pull must be simultaneous and explosive
✓Uchi mata is the most successful throw in Olympic judo history by competition statistics
✓It can be performed with a hopping entry (ken ken uchi mata), a leg-style entry (ashi uchi mata), or the standard hip-style entry
✓Set up uchi mata with forward pressure and gripping patterns that pull the opponent onto their toes
Common Mistakes
!Not entering deeply enough — your hip must be past the centre line of the opponent's body
!Sweeping the near leg instead of the far leg (inner thigh of the far leg is the target)
!Not pulling the opponent's weight forward onto their toes before sweeping — they sit back and resist
!Sweeping with a straight leg from too low — the sweep must arc upward between the legs with the back of your thigh
!Letting the standing leg drift — it must stay firmly planted under your centre of gravity
!Over-rotating the entry so the opponent falls beside you rather than over you
!Not maintaining the pull with the hands throughout — the hands drive the rotation while the leg provides the lift

Ashi Uchi Mata
GenusAshi Uchi Mata (leg-style inner thigh throw) is a variation in which the sweeping action is performed primarily with the lower leg rather than the thigh, with the thrower's foot or shin contacting the opponent's inner thigh to create a scooping, upward sweep. [1] This version emphasises the leg action over the hip rotation, making it particularly effective for taller judoka who can generate lifting force with a longer lever arm. [1,2] Ashi uchi-mata typically involves less turning than the standard version, with the thrower facing more sideways and relying on the extended leg reach to generate the throw. [2,3]

Ken Ken Uchi Mata
GenusKen Ken Uchi Mata (hopping inner thigh throw) is a dynamic variation in which the thrower hops forward on the supporting leg while driving the sweeping leg upward between the opponent's thighs, using the forward hopping momentum to generate additional throwing force. [1] The 'ken-ken' refers to the characteristic hopping motion on one foot that propels the thrower and opponent forward while the attacking leg sweeps. [1,2] This version is used when the initial uchi-mata entry does not fully break the opponent's balance, allowing the thrower to continue driving forward with hopping steps until the throw is completed. [2,3]

Standard Uchi Mata
GenusStandard Uchi Mata is the classical execution where the thrower grips the opponent's lapel and sleeve, turns in with the back to the opponent, and drives the sweeping leg upward between the opponent's thighs while pulling strongly with both hands to rotate the opponent over the hip and attacking leg. [1] The entry requires the thrower to pivot on the support foot, loading the opponent onto the hip and sweeping leg simultaneously. [1,2] The throw is completed when the sweeping leg lifts the opponent's centre of gravity past the point of no return, and the hand action wheels them over into a full rotation. [2,3]

Frequently Asked Questions
How do I throw someone much taller or bigger with uchi mata?
According to Fluid Judo Japan, the key is to tilt your opponent on their axis to shift their balance and lower the target in the thigh, since a tall opponent's center of gravity is high and harder to reach with a standard entry. Use a circular stepping pattern instead of a straight entry, point your supporting foot's toes outward, and use both hands to twist the opponent out of shape while pulling forward to break their posture.
What should I do if my opponent counters my uchi mata by bracing with their arm?
Fluid Judo Japan teaches that when your opponent stretches their elbow to brace against your uchi mata, swing your supporting elbow up to remove their hikite (sleeve hand) grip and block their counter. You can also try a pulling or dragging uchi mata with a top grip, bouncing the opponent's head up and down to make them brace forward instead of backward.
How can I chain uchi mata into other techniques?
Fluid Judo Japan emphasizes identifying your opponent's reaction to uchi mata and using it to transition into different techniques based on how they defend. For example, if they defend by bringing their knee in, you can use the same stepping pattern to switch to harigoshi and attack the outside of the knee instead of the inner thigh.
How does the Uchi Mata work?
