Kosoto Gari (Minor Outer Reap) is a fundamental judo-derived foot sweep that has become essential in modern BJJ’s standing game. Unlike explosive forward throws, Kosoto Gari capitalizes on subtle weight distribution, timing, and off-balancing to sweep the opponent’s weight-bearing leg from beneath them. The technique combines a pulling motion with upper body control while simultaneously reaping the opponent’s heel backward and upward. This creates a powerful rotation that deposits the opponent on their back, allowing immediate transition to dominant positions like side control or knee on belly. The beauty of Kosoto Gari lies in its mechanical efficiency - it requires minimal strength when executed with proper timing, making it accessible to practitioners of all sizes. The technique is particularly effective against opponents who resist forward throws by posting their weight backward, as this natural defensive reaction places them perfectly into Kosoto Gari’s zone of vulnerability. In competition, Kosoto Gari scores as a throw and frequently results in immediate positional dominance, making it a high-percentage technique for gi and no-gi contexts alike.

Playing as Attacker
Key Principles
-
Break opponent’s balance to rear corner (45-degree angle)
-
Control opponent’s upper body with strong collar and sleeve grips
-
Attack the weight-bearing leg at precisely the right moment
-
Combine pulling action with foot sweep in coordinated motion
-
Maintain forward pressure while sweeping backward
-
Follow opponent to ground for immediate top position
-
Use opponent’s resistance as fuel for the throw
Execution Steps
-
Establish grips: Secure deep collar grip with your right hand, fingers inside opponent’s collar at neck level. Left h…
-
Create initial off-balance: Pull opponent forward and slightly to their right front corner using both grips. This creates initia…
-
Step to optimal angle: Step your left foot forward and outside opponent’s right foot, positioning yourself at approximately…
-
Execute simultaneous pull and sweep: Explosively pull opponent’s upper body down and toward their right rear corner with both hands while…
-
Maintain forward pressure: As opponent falls backward, maintain constant forward pressure with your upper body, driving through…
-
Follow to top position: As opponent hits the mat, immediately step over or around their legs to establish side control or kn…
-
Consolidate position: Settle your weight into side control, cross-facing with your right arm while establishing underhook …
Common Mistakes
-
Attempting sweep before opponent’s weight is committed to rear leg
- Consequence: Opponent easily steps out of technique and may counter with their own throw. You expend energy with zero result and telegraph future attempts.
- Correction: Develop patience and sensitivity to weight distribution. Feel for the moment when opponent’s heel is weighted. Practice static drilling where partner indicates when their weight is back.
-
Sweeping too high on opponent’s leg (mid-calf or knee instead of heel)
- Consequence: Technique loses mechanical advantage and becomes strength-based. Opponent can simply resist with leg strength, nullifying the sweep.
- Correction: Focus sweep motion at heel specifically. Your foot should make contact with opponent’s heel and Achilles area. Think of fishing hook catching low on the leg.
-
Pulling with arms only, without full body commitment
- Consequence: Insufficient power generation leads to incomplete throw. Opponent may land in turtle or scramble position instead of flat on back.
- Correction: Pull with entire body - chest drives forward, hips rotate, arms extend fully. Imagine trying to pull opponent through yourself rather than just yanking with biceps.
Playing as Defender
Key Principles
-
Maintain dynamic weight distribution across both feet, never allowing weight to settle statically on the rear leg where it becomes vulnerable to the reap
-
Actively fight opponent’s collar grip establishment since deep collar control is the primary driver of the pulling force that creates the off-balance
-
Keep knees slightly bent with an athletic base that allows rapid weight transfers and foot repositioning in response to push-pull kuzushi patterns
-
Recognize the 45-degree angle step as the critical attack signal and respond before the coordinated pull-sweep begins executing
-
Prepare counter-attacks that exploit opponent’s base compromise during the sweep attempt, turning their offensive commitment into your advantage
-
Control distance through footwork to prevent opponent from establishing the close range needed for effective reaping contact with your heel
Recognition Cues
-
Opponent establishes deep collar grip at neck level and begins push-pull kuzushi sequence, first driving you forward then redirecting pressure toward your rear corner
-
Opponent steps their lead foot forward and outside your foot to approximately 45-degree angle, positioning their base alongside your weighted leg
-
You feel your weight shifting predominantly to one heel as opponent’s pulling action draws your upper body downward and toward your rear corner
-
Opponent’s sweeping leg begins moving toward your heel in a low arcing motion while their upper body drives forward with increasing pressure
-
Opponent’s sleeve grip tightens to prevent you from posting or adjusting while their collar grip pulls sharply downward and to the side
Defensive Options
-
Step back with the attacked leg before the sweep makes contact, removing the target and forcing opponent to reset - When: When you recognize the angle step and feel the initial pull toward your rear corner before the sweep reaches your heel
-
Drive forward aggressively into opponent’s chest, stuffing the backward pull and compromising their base for the sweep - When: When opponent begins the pulling action but has not yet initiated the foot sweep, timing the forward drive to beat the coordinated attack
-
Circle away from the sweep direction while breaking the collar grip with a two-on-one peel, removing both the pulling power and the angle needed for the reap - When: Early in the sequence when opponent is establishing grips and beginning the kuzushi pattern but before full commitment to the throw
Position Integration
Kosoto Gari serves as a critical bridge between standing engagement and ground-based BJJ, functioning as both an offensive weapon and a defensive counter in the standing phase. In modern BJJ competition, where many matches begin standing, having reliable takedown skills prevents being forced into disadvantageous guard pulls. Kosoto Gari integrates seamlessly with guard-pulling strategies - if opponent defends the throw effectively, you can transition to seated guard, De La Riva Guard, or X-Guard entries. From the defensive perspective, Kosoto Gari is an excellent counter when opponent attempts forward throws, allowing you to redirect their aggression while maintaining top position priority. The technique creates immediate path to Side Control, which is a cornerstone position in positional hierarchy, leading to mount, back control, or submission attacks. For competitors focused on points-based strategy, Kosoto Gari offers takedown points plus immediate positional dominance. The throw also has significant psychological impact, as landing hard on the back from a throw can demoralize opponents and affect their willingness to engage standing in subsequent exchanges.
