⚠️ SAFETY: North-South to Kimura targets the Shoulder joint (rotator cuff and ligaments). Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis). Release immediately upon tap.
The North-South to Kimura represents a highly effective transitional submission that exploits the inherent control advantages of the north-south position. This technique capitalizes on the opponent’s natural defensive reactions when pinned in north-south, specifically their tendency to push or frame against the top player’s hips and torso. The submission works by isolating the defending arm, securing the double-wrist grip characteristic of the kimura lock, and applying rotational pressure to the shoulder joint through controlled hip movement and proper positioning. What makes this particular entry so effective is the angle of attack - from north-south, the attacker can generate tremendous leverage while the defender’s escape options are severely limited. The position naturally restricts the opponent’s ability to roll out or extract their trapped arm, creating a high-percentage finishing opportunity. This technique is particularly valuable in gi and no-gi competition, as it can be applied from various north-south control positions and chains effectively with other submissions like the north-south choke and various arm attacks.

- Always allow clear tap access for the defensive hand
- Stop immediately at any sign of discomfort or resistance
- Never practice on opponents with pre-existing shoulder injuries without explicit permission and modified technique
- White belts should only drill this technique with controlled movement and no finishing pressure
Key Principles
- Establish dominant north-south control before attempting the submission transition
- Isolate the near arm by controlling the wrist and preventing elbow retraction
- Secure the figure-four grip with maximum mechanical advantage before initiating rotation
- Use hip pressure and chest weight to prevent opponent’s rotation or escape
- Apply rotational pressure through controlled hip movement, not arm strength
- Maintain perpendicular body alignment to maximize leverage and control
- Keep the opponent’s elbow close to your body throughout the submission sequence
Prerequisites
- Established north-south position with chest-to-chest pressure on opponent
- Opponent’s near arm extended or framing against your hips/torso
- Control of opponent’s wrist with your near hand
- Ability to thread your far arm under opponent’s trapped arm for figure-four grip
- Hip pressure preventing opponent’s hip escape or shrimping movement
- Opponent’s far arm controlled or isolated to prevent counter-attacks
- Proper weight distribution to maintain top position throughout transition
Execution Steps
- Secure North-South Control: Establish dominant north-south position with your chest driving into opponent’s chest. Your hips should be low and heavy, preventing their bridging or hip escape. Control the near arm by gripping their wrist with your same-side hand. Apply steady chest pressure to restrict their breathing and movement while keeping your base wide and stable. (Timing: 2-3 seconds to establish solid control) [Pressure: Firm]
- Isolate the Near Arm: Pull the opponent’s near arm away from their body by lifting their wrist while maintaining wrist control. Their natural reaction will be to push or frame against your hips. Use this reaction to your advantage by allowing slight extension of their arm while preventing them from pulling the elbow back to their body. Your grip on their wrist should be firm but not squeezing excessively. (Timing: 1-2 seconds) [Pressure: Moderate]
- Thread for Figure-Four Grip: While maintaining wrist control with your near hand, thread your far arm under their trapped arm, reaching across to grab your own wrist. Form the characteristic kimura figure-four grip with your wrists connecting. Your controlling hand should grip your opposite wrist from above, creating maximum structural strength. Ensure your forearm is positioned against their elbow, creating the fulcrum point for the leverage. (Timing: 2-3 seconds to secure proper grip) [Pressure: Moderate]
- Adjust Body Position: Shift your hips slightly toward the trapped arm side while keeping chest pressure on opponent. Your body should form a perpendicular angle to their torso. Keep your near knee posted on the mat for base, and your far leg extended for stability. This positioning maximizes your leverage while preventing opponent’s rotation or escape. Maintain constant pressure to keep them flat on their back. (Timing: 1-2 seconds) [Pressure: Firm]
- Initiate Controlled Rotation: Begin rotating the opponent’s arm by lifting their wrist toward their head while simultaneously pushing their elbow away from their body. The motion should be smooth and progressive, not sudden or jerking. Drive your hips forward slightly to increase pressure while rotating. Their hand should move in an arc motion toward their own head and away from their body. Watch for the tap signal continuously during this phase. (Timing: 3-4 seconds of progressive pressure) [Pressure: Firm]
- Finish with Hip Pressure: Complete the submission by driving your hips forward and down while maintaining the rotational pressure on the shoulder. Your chest should remain heavy on their torso, preventing any escape movement. Continue the controlled rotation until opponent taps. The finishing pressure comes from hip drive and body positioning, not from pulling with your arms. Maintain awareness of their tap signals and release immediately upon submission. (Timing: 2-3 seconds to finish) [Pressure: Maximum]
Opponent Defenses
- Opponent attempts to pull elbow back to body (Effectiveness: Medium) - Your Adjustment: Increase chest pressure to flatten them and use your figure-four grip to maintain arm extension. Pull their wrist toward their head while preventing elbow retraction with your forearm pressure.
- Opponent tries to roll into the submission (Effectiveness: Low) - Your Adjustment: Use your hip pressure and wide base to prevent the roll. If they commit to rolling, follow the motion while maintaining the figure-four grip and finish the kimura from the modified position.
- Opponent grabs their own belt or gi pants (Effectiveness: High) - Your Adjustment: Break the defensive grip by increasing rotational pressure and using your body weight. Alternatively, transition to armbar or north-south choke if the kimura becomes unavailable due to the strong defensive grip.
- Opponent bridges explosively to create space (Effectiveness: Medium) - Your Adjustment: Ride the bridge by keeping your hips low and following their movement. Maintain the figure-four grip and use their energy against them by increasing pressure as they settle back down. Keep your weight distributed across their chest to limit bridge effectiveness.
- Opponent attempts to frame against your head with free arm (Effectiveness: Low) - Your Adjustment: Control or trap their free arm by adjusting your head position and using shoulder pressure. Alternatively, pin their free arm to the mat with your head weight while maintaining the kimura grip with your arms. This prevents counter-attacks while you finish the submission.
Test Your Knowledge
Q1: What is the minimum application time for the kimura rotation in training to ensure safety? [SAFETY-CRITICAL] A: The kimura rotation should be applied slowly and progressively over a minimum of 3-5 seconds in training. This allows the training partner adequate time to recognize the danger, feel the pressure building, and tap safely before injury occurs. Competition speed should never be used in training for shoulder locks due to the high risk of serious injury including rotator cuff tears and shoulder dislocation.
Q2: Why is perpendicular body positioning critical for the north-south kimura finish? A: Perpendicular body positioning maximizes leverage by creating the optimal angle for rotational pressure on the shoulder joint. When your body is perpendicular to the opponent’s torso with hips angled toward the trapped arm, you can use your entire body weight and hip drive to generate finishing pressure. This positioning also prevents the opponent from rolling or bridging effectively to escape. Parallel positioning reduces leverage significantly and allows easier defensive options for the opponent including rotation and hip escape movements.
Q3: What are the primary injury risks if the north-south kimura is applied too quickly or aggressively? [SAFETY-CRITICAL] A: Rapid or aggressive application of the north-south kimura can cause several serious shoulder injuries: rotator cuff tears (affecting the supraspinatus, infraspinatus, teres minor, or subscapularis muscles with 3-12 month recovery and potential surgery), shoulder dislocation requiring 6-12 weeks minimum recovery with risk of chronic instability, labrum tears including SLAP lesions requiring 4-6 months and often surgical repair, AC joint separation with 4-8 week recovery, and glenohumeral ligament damage requiring 6-12 weeks healing. These injuries can be career-ending and cause permanent damage if the submission is applied recklessly.
Q4: How should you generate finishing pressure for the north-south kimura - with arm strength or hip pressure? A: Finishing pressure should be generated primarily through forward hip drive and body positioning, not arm strength. Your arms maintain the structural integrity of the figure-four grip while your hips drive forward and down to create the rotational force on the shoulder. This method provides smoother, safer, and more effective pressure compared to muscling the submission with arm strength. Using arms alone leads to jerky movements that increase injury risk and reduce control. Hip-driven pressure allows for more precise control and progressive application of force.
Q5: What is the correct release protocol when your training partner taps to the north-south kimura? [SAFETY-CRITICAL] A: Upon receiving the tap signal, immediately stop all rotational pressure on the shoulder. Release the figure-four grip and wrist control smoothly without jerking or pulling away suddenly. Allow the arm to return naturally to neutral anatomical position. Do not pull or push the arm as you release - let it move freely to wherever is comfortable for your partner. After release, check verbally with your training partner to ensure they are okay. The release must be immediate and controlled to prevent injury even after the tap has occurred.
Q6: What defensive reaction from the opponent makes the north-south kimura particularly effective? A: The opponent’s natural tendency to push or frame against the top player’s hips and torso when pinned in north-south creates the ideal setup for the kimura. This defensive framing extends their arm away from their body, allowing you to isolate and control the wrist easily. The extended arm position provides excellent access for threading your far arm underneath to secure the figure-four grip. Essentially, their defensive reaction to create space and prevent chest pressure directly sets up the submission opportunity, making this a high-percentage technique against common north-south defenses.
From Which Positions?
Expert Insights
- Danaher System: The north-south kimura represents one of the highest percentage shoulder lock entries in Brazilian Jiu-Jitsu due to the geometric advantages created by the perpendicular body alignment. From north-south, your ability to generate rotational force on the shoulder joint through hip pressure is maximized while simultaneously the opponent’s escape options are minimized. The critical technical element that most practitioners overlook is the timing of the grip transition - you must establish absolute control of the wrist before threading your far arm underneath. Many failed attempts occur because the practitioner rushes to secure the figure-four grip before achieving proper wrist isolation. The opponent’s most dangerous escape window is during this grip transition, so methodical progression is essential. From a safety perspective, the north-south kimura must be practiced with extreme care because the angle of attack creates tremendous mechanical advantage. In training, apply rotational pressure progressively over 3-5 seconds minimum and be hyperaware of your partner’s tap signals. The shoulder joint has limited tolerance for rotation under load, and the injuries sustained from overzealous application can be career-ending.
- Gordon Ryan: In competition, the north-south kimura is one of my highest percentage submissions from top position because opponents simply cannot defend it effectively once I secure the grip. The key difference between training and competition application is the speed and commitment - in training I apply this over 4-5 seconds with progressive pressure, but in competition I can finish in under 2 seconds if the opponent doesn’t tap immediately. That said, I still never spike or jerk the submission even in competition because injury to your opponent ends the match unsatisfyingly and creates unnecessary risk. The setup I prefer is to bait the opponent into framing against my hips when I transition to north-south from side control. Their push gives me the extended arm I need. Once I have the figure-four grip locked, I immediately angle my body perpendicular and drive my hips forward while lifting their wrist toward their head. Most opponents tap within seconds. If they try to roll into it, I follow the roll and finish from the modified position. The combination of north-south choke and kimura creates a devastating dilemma - if they defend the choke by pushing, they give me the kimura; if they keep arms tight for kimura defense, the choke is available.
- Eddie Bravo: From the 10th Planet perspective, the north-south kimura fits perfectly into our control-based submission system because it chains beautifully with other attacks from that position. What I emphasize to my students is that the kimura isn’t just a finish - it’s a control position that opens up multiple paths. If they defend the kimura by grabbing their belt or pants, you can transition immediately to an armbar or even work toward taking the back if they start rolling. The no-gi application requires slightly different grips since you can’t rely on gi fabric for control, so I teach using a gable grip or S-grip for the figure-four instead of the traditional wrist-on-wrist grip. This provides more security when everything is sweaty. One variation we use heavily is the rolling kimura from north-south where you purposely allow them to roll into the submission, then finish from the top position with them face-down. It’s unexpected and uses their defensive energy against them. Safety-wise, this submission requires serious respect - I’ve seen too many shoulder injuries from people cranking kimuras in training. In our gym, we have a strict culture of slow application and early tapping on all shoulder locks. The kimura is one of the most dangerous submissions when applied recklessly.
