SAFETY: Kimura from North-South targets the Shoulder joint, rotator cuff, and surrounding ligaments. Tap early and often. Your safety is more important than any training round.
Defending the Kimura from north-south requires early recognition and immediate preventive action, as the deceptive leverage angle of this position can generate dangerous shoulder torque with minimal warning. The defender’s primary challenge is that north-south chest pressure restricts breathing and mobility, limiting the defensive tools available compared to defending Kimuras from side control or guard. Your arms are the primary targets, and the attacker’s perpendicular hip alignment gives them a significant mechanical advantage once the figure-four grip is secured. Successful defense depends on a layered approach: first, preventing arm isolation by keeping elbows tight and hands fighting for inside position; second, disrupting the figure-four grip before it consolidates; and third, using explosive hip movement and rolling mechanics to escape if the grip is established. The north-south Kimura defense is time-sensitive—once the attacker has a secure figure-four with proper hip angle and begins rotational pressure, your defensive options narrow rapidly to tapping. Understanding the specific windows where each defensive layer is most effective separates experienced defenders from those who are caught repeatedly.
Opponent’s Starting Position: North-South (Top)
How to Recognize This Submission
How do you know when someone is attempting Kimura from North-South?
- Attacker’s hand slides underneath your forearm or reaches for your wrist while maintaining north-south chest pressure
- You feel the attacker shift their weight to one side while one of their arms threads over the top of your arm toward their own wrist
- Attacker adjusts their hips to a more perpendicular angle relative to your body while maintaining chest contact
- You feel a figure-four grip configuration locking around your arm with increasing tightness at the elbow and wrist
Key Defensive Principles
What are the key principles for defending Kimura from North-South?
- Keep elbows pinned tight to your ribcage at all times to prevent arm isolation and deny the attacker wrist control
- Fight hands immediately when you feel wrist control being established—grip fighting before the figure-four locks is your highest-percentage window
- Use hip movement to create angles that reduce the attacker’s chest pressure and disrupt their perpendicular alignment
- Roll toward the submission (into the attacker) rather than away when the figure-four is locked—rolling away increases shoulder torque
- Tap early and decisively—the north-south angle creates deceptive leverage that can cause injury faster than you expect
Defensive Options
What can you do to defend against Kimura from North-South?
1. Pull elbow tight to ribs and turn arm inward to deny wrist control
- When to use: At the earliest recognition cue—when you feel the attacker reaching for your wrist before the figure-four grip is established
- Targets: North-South
- If successful: Attacker cannot establish the figure-four grip and must abandon the Kimura attempt, returning to standard north-south control
- Risk: Low risk. Keeping elbows tight is always a safe defensive posture from north-south bottom
2. Bridge explosively and hip escape toward the attacked arm side to disrupt attacker’s base and perpendicular alignment
- When to use: When the figure-four grip is partially established but rotational pressure has not yet begun—this is your last high-percentage window
- Targets: Half Guard
- If successful: Creates enough disruption to break the figure-four or force the attacker to abandon the submission to maintain position, allowing guard recovery
- Risk: Medium risk. A poorly timed bridge wastes energy and may actually improve the attacker’s grip if they absorb the movement
3. Roll toward the attacker (into the Kimura) to relieve rotational pressure and expose their back
- When to use: When the figure-four is fully locked and rotational pressure has begun—this is your emergency escape when prevention has failed
- Targets: Half Guard
- If successful: Relieves shoulder torque by following the rotation direction, and may expose attacker’s back for a reversal or force them to release the grip to maintain position
- Risk: Medium-high risk. If the attacker follows your roll while maintaining the grip, they can continue the submission from the new angle
4. Grab your own wrist or grip your gi/shorts to create a defensive anchor against rotation
- When to use: When the figure-four is established but you need to buy time to set up a bridge or roll escape
- Targets: North-South
- If successful: Temporarily stalls the rotational pressure and gives you time to set up a more complete escape sequence
- Risk: High risk as a standalone defense. The attacker can often overcome this grip with sustained pressure, and your arm remains trapped in a vulnerable position while you hold
Escape Paths
How do you escape Kimura from North-South?
- Bridge and hip escape toward the attacked side to break the figure-four grip and recover to half guard or closed guard
- Roll into the attacker (toward the Kimura side) to relieve shoulder pressure, potentially reaching turtle or exposing their back for a reversal
- Straighten the trapped arm explosively before the figure-four consolidates, then retract the elbow tight to your body to reset to north-south defense
Best-Case Outcomes for Defender
What is the best outcome when defending Kimura from North-South?
→ North-South
Deny the figure-four grip entirely by keeping elbows tight and fighting wrist control. The attacker abandons the Kimura attempt and returns to standard north-south pressure, allowing you to work standard north-south escapes.
→ Half Guard
Time an explosive bridge during the attacker’s grip transition to disrupt their base and perpendicular alignment. As they lose chest pressure, insert your knee to recover half guard and begin working standard guard retention.
