Standard O Uchi Gari
Genus大内刈り(O Uchi Gari)
TraditionalTranslation: major inner reap
Overview
Standard O Uchi Gari executes the classical major inner reap where the thrower steps between the opponent's legs, hooks the far leg's inner ankle or calf with the sole of the foot, and reaps it backward while driving the opponent's upper body rearward with the hands. [1] The opponent, losing their far support, falls backward diagonally over the reaped leg. [1],[2] The throw requires the thrower to commit their weight forward into the space between the opponent's legs while maintaining balance on the support foot. [2],[3]
History & Origin
Effectiveness
O uchi gari is one of the most effective combination-starter throws in judo, frequently used to drive the opponent backward and create openings for forward-attacking techniques like seoi nage and uchi mata. [1] As a standalone throw, it produces ippon when the reaping action catches the opponent's full weight on the targeted leg. [2] Its effectiveness is amplified by its low risk — failed attempts rarely result in counter-throws because the attacker maintains an upright posture. [3]
Lineage
Competition Record
O uchi gari ranks consistently among the most frequently attempted throws at IJF World Championships, though its ippon rate is lower than forward throws because it is more commonly used as a combination setup. [1] Toshihiko Koga (JPN, 1991 World Champion, 1992 Olympic gold) was noted for using o uchi gari as a primary setup for his devastating ippon seoi nage combinations. [2]

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 judo grip — Drive the opponent's weight onto their near foot, hook or reap the inside of the leg while pulling the upper body in the opposite direction
From clinch — Push the opponent to load the front leg, then hook the ankle or calf from inside while twisting the upper body
Variants
Standing reap — full commitment reap with maximum body weight behind the throw
Hopping reap — hopping forward while reaping for deeper penetration
Combination reap — chaining inside and outside reaps to catch the opponent adjusting
Counter reap — reaping as the opponent steps forward or attacks

FIAS Combat Sambo RulesPDFTraining Notes
✓From standard grips, push the opponent slightly to break their balance backward
✓Step your lead foot between the opponent's feet
✓Reap the opponent's far leg from inside to outside with the back of your calf, catching their ankle
✓Push the opponent's upper body backward and slightly sideways with both hands while the reap removes their base
✓The opponent falls backward over the reaped leg
✓Follow the opponent to the ground, maintaining grip for transition to ground work
✓Drill the stepping pattern — step between, reap, push — until the three-beat rhythm becomes automatic
Common Mistakes
!Not stepping between the opponent's feet first — reaping from outside range results in a weak, glancing reap
!Reaping upward instead of backward — the calf sweeps the ankle backward, not upward
!Not pushing the opponent's shoulders backward in coordination with the reap
!Reaping too high on the leg — the ankle is the target for maximum mechanical advantage
!Losing your own balance forward during the push
!Leaving your head down during the throw — keep the posture upright
!Not controlling the fall — maintain grip to follow the opponent to the mat safely

Frequently Asked Questions
How do I control my opponent's posture before attempting o uchi gari?
Shintaro Higashi emphasizes keeping your hand higher to control your opponent's posture better than they can control yours. Position comes first—establish this control before you attack the technique.
Should I pull my opponent toward me when setting up o uchi gari?
No. Shintaro Higashi explains that pulling your opponent toward you breaks their posture forward, which doesn't help you throw them. Instead, drive their weight back, close the distance, and lock your chest up.
What should I do if my opponent resists my first o uchi gari angle?
Shintaro Higashi teaches that if your opponent shifts away to defend one direction, you can pivot and punch the hand to the chin, push their head to the outside of their foot, and drive them toward you from a different angle.
Why do beginners struggle against o uchi gari counters?
Shintaro Higashi notes that beginners often lack good off-balance (kuzushi) when setting up o uchi gari, making them vulnerable to the opponent's natural counter—the leg sweep defense is an intuitive, soccer-like movement that's easy to execute without proper technique from the attacker.
