SAFETY: Kimura from Shoulder of Justice targets the Shoulder joint (glenohumeral) and elbow. Risk: Shoulder dislocation or subluxation from forced internal rotation beyond anatomical limits of the glenohumeral joint. Release immediately upon tap.
From the Shoulder of Justice, the Kimura becomes available when your intense jaw pressure forces the opponent to extend their near arm for relief. This reactive arm extension creates the opening for a figure-four grip that attacks the shoulder through forced internal rotation. The key offensive principle is maintaining positional pressure throughout the submission attempt—your shoulder pressure, hip connection, and base must remain intact even as you transition to the kimura grip. The position naturally creates the submission opportunity through a pressure dilemma: the opponent must either endure the unbearable jaw pressure or extend their arm and face immediate kimura attack. Your role is to recognize the arm extension instantly, secure the figure-four before they retract, and finish with controlled rotational pressure using your entire body rather than arm strength alone.

Key Attacking Principles
What are the key principles for executing Kimura from Shoulder of Justice?
- Maintain shoulder pressure throughout the kimura setup to prevent the opponent from recovering defensive posture or retracting their arm
- Secure the figure-four grip with hands clasped tightly at the wrist before attempting any rotational pressure on the shoulder
- Keep hips low and connected to the opponent’s hip line during the grip transition to prevent shrimping escapes
- Drive the rotation using your entire upper body as a single unit rather than muscling the finish with your arms alone
- Control the opponent’s elbow tight against your chest to create maximum rotational leverage on the glenohumeral joint
- Recognize when to switch between traditional and belly-down finishing positions based on the direction and strength of the opponent’s resistance
Prerequisites
What do you need before attempting Kimura from Shoulder of Justice?
- Established Shoulder of Justice with shoulder driven into opponent’s jaw at approximately 45-degree angle toward their far shoulder
- Hips connected to opponent’s near hip line with low base preventing shrimping movements
- Opponent’s near arm accessible—either extended for pressure relief, framing against your chest, or controllable at the wrist
- Stable base with far knee posted wide to maintain balance during the grip transition phase
- Opponent flat on their back with limited hip mobility from sustained shoulder and chest pressure
Execution Steps
How do you execute Kimura from Shoulder of Justice step by step?
- Identify the trigger arm extension: When the opponent extends their near arm to push away your shoulder pressure or creates a frame against your chest, recognize this immediately as the kimura trigger. Your sustained jaw pressure should have forced this reaction—the arm extension is the instinctive response to relieve discomfort. Maintain your shoulder drive while shifting your focus to securing the exposed wrist before they retract. (Timing: Immediate recognition required—window lasts 1-2 seconds before opponent retracts arm)
- Secure the wrist with crossface hand: With your crossface hand (nearest their head), slide down and grip their exposed wrist firmly using a C-grip with your thumb on the inside of their wrist. Maintain shoulder pressure into their jaw throughout this transition—do not lift your shoulder to reach for the grip, as this releases the pressure that created the opportunity and gives them time to retract the arm defensively. (Timing: 0.5-1 second transition from crossface to wrist control)
- Pin the captured arm to the mat: Drive their captured wrist toward the mat beside their hip to flatten and isolate their arm against the ground. This pins the shoulder joint in a vulnerable position and prevents them from bending the elbow to create defensive angles. Your far hand now begins threading under their upper arm, passing between their elbow and their body to establish the figure-four lock foundation. (Timing: 1-2 seconds to flatten arm and begin threading)
- Establish the figure-four kimura grip: Thread your far arm under their tricep and grip your own wrist firmly to create the complete figure-four kimura lock. Your grip must be tight with zero slack—their elbow must be pinned close to your chest for maximum mechanical control. Squeeze your elbows together to compress their arm tightly against your torso, eliminating any space they could exploit to rotate free or regrip defensively. (Timing: 1-2 seconds to complete grip—speed matters to prevent clasped-hands defense)
- Transition weight for rotational clearance: Release your shoulder pressure from their jaw and sit your hips back slightly to create the rotational space needed to finish the submission. Keep their elbow pinned tightly against your chest throughout this weight shift. Begin rotating their forearm toward their back in a controlled paint-brush arc, using your entire upper body as a single rotating unit rather than muscling with your hands alone. (Timing: 1-2 seconds to transition weight and begin rotation)
- Apply controlled finishing rotation: Drive their hand in a slow, controlled arc toward their opposite hip. The rotation forces internal rotation of the glenohumeral joint beyond its natural anatomical limits, creating intense pressure on the shoulder capsule and rotator cuff. Apply pressure progressively and steadily—never jerk or spike the submission, as catastrophic shoulder injury can occur faster than the opponent can signal a tap. (Timing: 2-4 seconds of progressive rotational pressure)
- Counter clasped-hands defense or secure the tap: If the opponent clasps their hands together to resist the rotation, step your far leg over their head and transition to a belly-down finishing position. Drop your hips flat to the mat and extend your body to generate significantly greater breaking leverage against their clasped grip. If no grip defense, maintain steady rotational pressure until you receive a clear tap signal and release immediately. (Timing: 2-3 seconds for belly-down transition if needed)

Opponent Defenses
How might your opponent defend against Kimura from Shoulder of Justice?
- Opponent clasps hands together to prevent arm isolation and rotation (Effectiveness: High) - Your Response: Step far leg over their head and transition to belly-down kimura finish for dramatically increased leverage to break the grip. Alternatively, release one hand to peel their gripping fingers apart before re-securing the figure-four. → Leads to Shoulder of Justice
- Opponent bridges and rolls toward you during the grip transition to disrupt your base (Effectiveness: Medium) - Your Response: Follow the roll while maintaining the figure-four grip and finish the kimura from the new top position after the roll completes. The grip remains effective regardless of which side you end up on. → Leads to Half Guard
- Opponent shrimps hips away explosively to create distance and recover guard during setup (Effectiveness: Medium) - Your Response: Follow their hips maintaining the grip and transition to a mounted kimura or abandon the submission attempt and re-establish Shoulder of Justice pressure before they complete guard recovery. → Leads to Half Guard
- Opponent straightens their arm fully to prevent the figure-four from closing (Effectiveness: Medium) - Your Response: Transition to an armbar by swinging your leg over their face while maintaining wrist control on the straightened arm. Their straight-arm defense against the kimura creates a direct armbar opportunity. → Leads to Shoulder of Justice
