Defending Kosoto Gake requires early recognition and immediate action because the throw’s simplicity means it executes quickly once committed. The defender’s primary objective is to deny the two essential conditions for the throw: rearward weight loading on the target leg and close upper body control by the attacker. Because Kosoto Gake relies on a force couple between the upper body pull and leg reap, disrupting either component neutralizes the entire technique. The most effective defensive window is during the setup phase before the attacker positions their reaping leg. Once the reap begins, defensive options narrow significantly but recovery is still possible through proper base adjustment and counter-pressure. Understanding Kosoto Gake defense is essential for any practitioner who engages in standup exchanges, as it is one of the most commonly attempted throws in BJJ competition due to its accessibility and reliability.
Opponent’s Starting Position: Standing Position (Top)
How to Recognize This Attack
- Attacker establishes collar grip and begins pulling your upper body backward while stepping to a 45-degree angle relative to your stance
- Attacker’s rear leg lifts and moves behind your rear leg, with their calf seeking contact with the back of your lower leg
- You feel a distinct backward pulling force through your collar or neck combined with the attacker closing distance to chest-to-chest range
- Attacker’s weight shifts entirely to their front supporting leg as they prepare to commit their rear leg to the reaping motion
- Attacker breaks your posture with a sudden downward-backward jerk on your collar while simultaneously stepping to the outside of your rear leg
Key Defensive Principles
- Maintain dynamic weight distribution across both legs to deny the attacker a heavily loaded target leg
- Deny close distance by using frames and grip fighting to prevent chest-to-chest contact
- Recognize the setup early through grip patterns and angle changes rather than reacting to the reap itself
- Counter the backward pull by driving hips forward and maintaining upright posture
- Keep feet active with small adjustments rather than planting in a static wide stance that creates easy targets
- Disrupt the attacker’s grip configuration before they can establish the pull-and-reap coordination
Defensive Options
1. Step your rear leg backward and away from the reap, shifting weight to your front leg
- When to use: When you feel the attacker positioning their leg behind yours but before the reap is fully committed
- Targets: Standing Position
- If successful: Attacker’s reap contacts empty space, you return to neutral standing with grip fighting advantage as they recover balance
- Risk: Attacker chains to Kosoto Gari or Osoto Gari targeting the leg you stepped onto
2. Drive hips forward aggressively and circle toward the attacker’s reaping leg side to kill the angle
- When to use: When you feel the backward pull on your upper body beginning and recognize the throw setup in its early phase
- Targets: Standing Position
- If successful: Your forward pressure neutralizes the backward pull and eliminates the angle needed for the reap, returning to neutral clinch engagement
- Risk: If attacker reads your forward drive, they may redirect into a different throw using your forward momentum against you
3. Strip the attacker’s collar grip with a two-on-one grip break while posting your free hand on their hip to create distance
- When to use: Early in the setup phase when attacker is establishing the grip configuration but has not yet committed to the throw
- Targets: Standing Position
- If successful: Without the collar grip, the attacker cannot generate the backward pulling force needed for the throw, resetting to neutral grip fighting
- Risk: If grip break is slow, attacker may complete the throw during your grip fighting attempt
4. Turn into the attacker and attack with your own underhook or guillotine threat to counter their forward commitment
- When to use: When the attacker has committed to the throw but you have maintained enough posture to counter-attack
- Targets: Clinch
- If successful: Your counter-rotation disrupts the throw mechanics and establishes your own offensive position in the clinch or secures a submission grip
- Risk: If your counter-attack timing is late, you may still be thrown while turning, landing in a worse position
Best-Case Outcomes for Defender
→ Standing Position
Deny the throw by stepping your rear leg away from the reap, stripping the collar grip with a two-on-one break, or driving your hips forward to neutralize the backward pull. Return to neutral standing and re-engage grip fighting from an advantageous position since the attacker has expended energy on a failed attempt.
→ Clinch
Turn into the attacker during their throw attempt to establish your own clinch grips. Use an underhook or collar tie on the side they are attacking to redirect their momentum. Even if you end up in a slightly disadvantageous clinch position, you have prevented the takedown to side control which is a far worse outcome.
Test Your Knowledge
Q1: What is the earliest recognition cue that your opponent is setting up Kosoto Gake? A: The earliest cue is feeling a distinct backward pulling force through your collar combined with the attacker stepping to a 45-degree angle relative to your stance and closing distance to chest-to-chest range. This combination of collar pull, angle change, and distance closing precedes the actual leg positioning and gives you the maximum defensive window to respond before the reap is committed.
Q2: Why is driving your hips forward more effective than leaning your shoulders backward when defending the throw? A: Driving hips forward shifts your center of gravity over your base of support (your feet), which is the opposite of what the attacker needs. Leaning your shoulders backward actually helps the attacker because it loads more weight onto your rear leg while moving your center of gravity behind your base. The hip-forward drive also creates forward pressure that disrupts the attacker’s pulling mechanics and can off-balance them in return.
Q3: Your opponent has already positioned their calf behind your rear leg and is beginning the reap - what is your best remaining option? A: At this late stage, your best option is to turn sharply into the attacker’s body while simultaneously posting your near hand on their hip to create a frame. This turning motion redirects the force of the reap along a different axis than the attacker intended, potentially fouling their throw mechanics. If the throw still partially succeeds, the turn means you land in a scramble position rather than flat on your back in side control, giving you a chance to recover guard or establish your own grips.
Q4: How should you adjust your defensive strategy when you recognize your opponent is chaining Kosoto Gake with Osoto Gari? A: When facing a Kosoto Gake to Osoto Gari chain, avoid the instinct to simply step your rear leg backward repeatedly, as this plays directly into the chain system. Instead, address the root cause by stripping the collar grip that powers both throws. If grip stripping is not immediately possible, circle laterally rather than stepping linearly backward, which denies the straight-line angle both throws require. You can also consider pulling guard strategically to deny the standing exchange entirely rather than defending an escalating chain.
Q5: What specific footwork pattern should you maintain to minimize vulnerability to Kosoto Gake? A: Maintain a slightly staggered stance with active small shuffling movements that keep weight distributed dynamically between both feet rather than committing heavily to either leg. Avoid standing square to your opponent with equal weight on both feet, as this creates a clear rear-leg target. Instead, use constant micro-adjustments where your weight shifts rhythmically so the attacker cannot predict which leg is loaded at any given moment. When you feel the opponent establishing collar control, immediately begin circling toward their reaping-side hip to deny the angle.
