Standard Uchi Mata
Genus内股(Uchi Mata)
TraditionalTranslation: inner thigh throw
Overview
Standard 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]
History & Origin
Effectiveness
Uchi mata is widely regarded as the single most effective throw in judo competition, consistently ranking as the highest-scoring technique at World Championships and Olympic Games across multiple decades. [1] Daigo notes that uchi mata's versatility — adaptable to virtually any grip configuration and effective against opponents of all body types — makes it the most universally applicable throwing technique. [2] The throw generates exceptionally high impact force due to the combination of hip rotation and the upward lever action of the sweeping leg, producing clean ippon scores at a higher rate than most other techniques. [3]
Lineage
Uchi mata was codified by Jigoro Kano as part of the original Kodokan nage-waza curriculum and is classified as an ashi-waza technique in the Kodokan gokyo. [1] The technique was refined into a dominant competition weapon by successive generations of Kodokan and university judo practitioners, with notable contributions from Kyuzo Mifune (10th dan), who demonstrated its application with extraordinary timing. [2] In the modern era, the technique has been carried forward through virtually every Kodokan-lineage school worldwide. [3]
Competition Record
Uchi mata has produced more ippon victories at the Olympic Games and World Judo Championships than any other single technique. [1] Notably, Kosei Inoue (JPN) used uchi mata as his primary technique to win the 2000 Sydney Olympics gold medal at 100 kg and three consecutive World Championship titles (1999, 2001, 2003). [2] Shohei Ono (JPN) won the 2016 Rio Olympics gold at 73 kg with uchi mata as a core weapon. [3] Statistical analyses of IJF World Tour events consistently place uchi mata among the top three scoring techniques across all weight categories. [1]

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
Variants
Standard hip throw — full turn-in with hip below the opponent's centre of gravity
No-gi hip throw — adapted without gi grips, using overhook and collar tie
Drop hip throw — dropping to one knee to lower the fulcrum point
Combination hip throw — chaining from a failed foot technique or hand technique

FIAS Combat Sambo RulesPDFTraining Notes
✓From standard grips, pull the opponent forward to break their posture
✓Step across with your lead foot, placing it between the opponent's feet
✓Turn your back to the opponent, pivoting on the lead foot while swinging the rear leg between their legs
✓The back of your thigh contacts the inner thigh of the opponent's far leg and sweeps upward explosively
✓Simultaneously pull the opponent's upper body forward and down with both hands — rotating them over your leg and hip
✓The throw finishes with a full rotation — the opponent goes over your body to the mat
✓Your head stays up and your chest stays open throughout — do not duck or bend forward
Common Mistakes
!Stepping too far to the side instead of between the opponent's feet — the entry must be central
!Not sweeping upward with enough force — the thigh must drive up with explosive leg extension
!Bending at the waist during the entry, which lowers your head and weakens the throw
!Not turning the back fully to the opponent — incomplete rotation results in a weak, off-angle throw
!Sweeping the near leg instead of reaching between for the far leg
!Releasing the grip during the throw and losing control
!Landing on top of the opponent without control — maintain the grip to land in a dominant position

Frequently Asked Questions
Should I grip the lapel or the back when setting up an uchi mata?
Sampson Judo recommends holding onto the traditional lapel grip because it gives you better control—when you break your opponent's balance, your hand can come underneath to elevate and control them more effectively.
How do I prevent my opponent from sliding away after I break their balance?
Once you break someone's balance to their toes, it's critical to keep them there and not let them slide backwards. Maintain that position while you execute the foot work for the throw.
What's the correct foot placement for the sweeping leg in uchi mata?
Your left foot should come inward and step roughly inside your opponent's thigh of the leg you're sweeping—this leg action guides the throw as a sweeping motion, even though the power comes from the hips.
Where should my elbow be positioned to maximize leverage?
Keep your elbow nice and low—this position creates extra leverage for elevating and controlling your opponent during the throw.
