Ouchi Gari (major inner reaping throw) is a fundamental judo technique that has become an essential tool in Brazilian Jiu-Jitsu’s standing game. The technique involves reaping the opponent’s lead leg from the inside while simultaneously breaking their posture and balance to the rear corner. Unlike pure throwing arts where the goal is a clean ippon, BJJ practitioners use Ouchi Gari both as a takedown to achieve dominant top position and as a setup for other attacks when the opponent defends. The technique’s effectiveness lies in its ability to capitalize on natural standing posture—most grapplers stand with weight distributed between both legs, making them vulnerable to this inside leg attack. When executed properly, Ouchi Gari creates a powerful combination of off-balancing, sweeping action, and forward pressure that makes it extremely difficult for the opponent to maintain their base. The technique integrates seamlessly with BJJ’s ground game, as a successful Ouchi Gari typically lands the practitioner in side control or a transitional position from which mount or back control can be achieved. Its versatility makes it valuable across all rulesets, from IBJJF competition to no-gi grappling and MMA applications.

Playing as Attacker
Key Principles
-
Control opponent’s posture through collar and sleeve grips before initiating throw
-
Break opponent’s balance to their rear corner (backward and slightly to their supporting leg side)
-
Reap the inside of opponent’s lead leg with your corresponding leg in a sweeping motion
-
Drive forward and down with your upper body while reaping to prevent recovery
-
Keep your base leg strong and stable throughout the execution
-
Maintain tight connection to opponent’s body to control their fall and landing position
-
Time the attack when opponent steps or shifts weight onto their lead leg

Establish dominant grips: Secure a high collar grip with your right hand (on opponent’s left lapel or behind their neck in no-…

Common Mistakes
-
Attempting the throw from too far away without proper entry step
- Consequence: Reaping leg cannot reach opponent’s leg effectively, making the technique weak and easily defended. You end up off-balance without achieving the throw.
- Correction: Always take a committed step in with your left foot, closing the distance until your hips are near theirs before attempting the reap. The throw requires close-range execution.
-
Reaping with the wrong leg (outside leg instead of inside)
- Consequence: This creates an Osoto Gari (major outer reap) instead, which may work but requires different mechanics and setup. Using the wrong leg reduces effectiveness significantly.
- Correction: Remember that Ouchi Gari uses the inside leg—your right leg attacks their right leg from the inside position. Drill the proper leg selection pattern until it becomes automatic.
-
Failing to break opponent’s posture before attempting the throw
- Consequence: Opponent maintains upright balance and can easily step out of the technique or counter with their own attack. The throw lacks the necessary off-balancing component.
- Correction: Always pull down and back with your grips first, creating the postural break. Wait to feel their weight shift backward before initiating the leg reap. Timing is crucial.
Playing as Defender
Key Principles
-
Maintain strong upright posture with knees slightly bent and weight on the balls of your feet to resist the backward off-balancing that precedes the reap
-
Deny the attacker’s grip establishment through active hand fighting, particularly preventing the high collar grip that provides leverage for kuzushi
-
Keep your lead leg light and mobile so you can retract it quickly when you feel the inside reaping attempt begin
-
Control distance to prevent the attacker from stepping close enough to execute the reap—the technique requires close proximity to work
-
Recognize the entry pattern early (grip tightening, forward step, posture break attempt) and respond before the reap begins rather than after
-
Maintain circular movement rather than standing static, as Ouchi Gari is most effective against stationary opponents with predictable weight distribution
Recognition Cues
-
Opponent tightens their collar grip and pulls downward while simultaneously stepping their lead foot forward and to the outside of your foot, closing distance rapidly
-
You feel a distinct backward and downward pull through the grips combined with opponent’s chest pressing into yours, indicating they are attempting to break your posture to the rear corner
-
Opponent’s leg begins moving between your legs from the inside, with their calf or shin making contact against the back of your lead leg in a sweeping arc motion
-
Opponent shifts their weight onto one leg (their base leg) while their other leg lifts and drives inward, and their upper body leans into you with increased forward pressure
-
A sudden change in grip intensity—the collar grip gets sharply pulled while the sleeve grip either pushes or pulls your arm to prevent posting—signals the throw is being initiated
Defensive Options
-
Step back and retract the attacked leg before the reap makes contact, pulling your lead foot behind your base foot while maintaining grip control and posture - When: As soon as you feel the initial kuzushi (backward pull) and sense the opponent’s leg beginning to move toward your inside leg. This must be done early—before the reaping leg hooks behind your calf.
-
Sprawl your hips back and down while posting your hands on opponent’s shoulders or head, creating distance that prevents the reaping leg from reaching your leg effectively - When: When the opponent has already stepped in close and you cannot retract your leg in time. The sprawl removes your hips from their reach and puts your weight on their upper body, collapsing their throwing structure.
-
Circle laterally away from the direction of the reap while breaking the collar grip, denying both the angle and the grip control needed to complete the throw - When: When you recognize the setup early during the grip-fighting phase before the opponent has fully closed distance. Circling works best as a preemptive defense when you sense the opponent loading up for the attack.
Position Integration
Ouchi Gari serves as a fundamental bridge between BJJ’s standing game and ground game, fitting into the broader takedown system as a reliable offensive technique from clinch positions. In the context of positional hierarchy, successful execution of Ouchi Gari typically results in side control top or transitional positions that lead to mount or back control—all highly advantageous positions worth 3-4 points in IBJJF competition. The technique integrates particularly well with BJJ’s grip fighting game, as it requires the same collar and sleeve controls that set up other attacks like guard pulls, single legs, and various judo throws. Strategically, Ouchi Gari functions as both a primary attack and a combination technique—when opponents defend against your other standing attacks (such as Osoto Gari or single leg takedowns), their defensive positioning often creates openings for Ouchi Gari. From a systems perspective, this technique is essential for any BJJ practitioner developing a well-rounded takedown game because it works across all rule sets (gi, no-gi, and submission-only), requires no exceptional physical attributes, and creates opportunities for immediate ground control. Many high-level BJJ competitors use Ouchi Gari as their primary takedown specifically because it lands them in positions they want to be in (top side control) rather than neutral positions like double guard pull scenarios. The technique also chains effectively with ground entries—if the throw is partially successful but doesn’t result in a full takedown, the reaping position often provides access to single leg attacks or front headlock positions that transition smoothly into submission-oriented ground control.
