SAFETY: Kimura from Kimura Trap targets the Shoulder joint (glenohumeral) and elbow. Risk: Shoulder dislocation (glenohumeral subluxation or full anterior dislocation). Release immediately upon tap.
The Kimura from Kimura Trap is the primary finishing technique within the Kimura Trap system, converting established figure-four grip control into a devastating shoulder lock. This submission uses rotational force against the glenohumeral joint by driving the opponent’s hand behind their back in a controlled arc motion. Unlike isolated Kimura attempts from side control or guard, this finish benefits from the systematic control infrastructure already established through the Kimura Trap position—the opponent’s arm is deeply compromised, their base disrupted, and defensive options severely constrained by the preceding positional control and grip depth.
The finishing mechanics demand precise angle creation through walking the feet toward the opponent’s head, progressive rotational pressure coordinated with hip positioning rather than arm strength, and unwavering chest pressure that prevents the opponent from creating escape space. The figure-four grip structure multiplies mechanical advantage at the shoulder joint, making the finish achievable even against significantly stronger opponents when proper technique and angle are applied consistently.
Strategically, the Kimura from Kimura Trap creates compounding dilemmas: defending the finish typically forces the opponent to compromise positional integrity, opening sweeps, back takes, or transitions to alternative submissions like the Americana or armbar. Even when the finish itself does not produce the tap, the constant rotational threat creates defensive reactions that advance the attacker’s position, embodying modern BJJ’s emphasis on interconnected attacking systems rather than isolated techniques.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Shoulder dislocation (glenohumeral subluxation or full anterior dislocation) | CRITICAL | 3-12 months, may require surgical repair of labrum and ligaments |
| Rotator cuff tear (supraspinatus, infraspinatus, or subscapularis tendon damage) | High | 4-8 months with possible surgical intervention |
| Medial collateral ligament strain of the elbow from combined rotation and extension force | Medium | 2-6 weeks with rest and progressive rehabilitation |
Application Speed: SLOW and progressive. The Kimura generates enormous torque on the shoulder joint through the figure-four lever. Apply rotational pressure gradually in a smooth arc, allowing the opponent adequate time to recognize the threat and tap. Never jerk, spike, or explosively wrench the arm behind the back.
Tap Signals:
- Verbal tap (saying ‘tap’ or any distress vocalization)
- Physical hand tap on partner, mat, or own body with free hand
- Physical foot tap on mat with either leg
- Any unusual screaming, grunting, or visible facial distress indicating pain
Release Protocol:
- Release all rotational pressure immediately upon any tap signal without hesitation
- Return opponent’s arm gently to a neutral anatomical position after releasing the grip
- If in doubt about whether a signal was a tap, release immediately—the position can always be re-established
- Check on training partner’s shoulder condition and range of motion after release before continuing
Training Restrictions:
- White belts should drill at controlled speed without full rotational pressure until they demonstrate consistent grip mechanics and tap recognition
- Never apply the Kimura with explosive or jerking force in training—always use slow progressive pressure that allows the partner to tap safely
- Avoid applying this technique to training partners with known shoulder injuries, prior dislocations, or hypermobility conditions
- In competition, release immediately upon tap regardless of perceived submission legitimacy or referee response time

Playing as Attacker
Key Principles
-
Verify deep figure-four grip positioning near the opponent’s elbow before committing to the finish—shallow grips near the wrist lack sufficient leverage
-
Create the finishing angle by walking feet in an arc toward the opponent’s head rather than attempting to finish from a squared-up position
-
Generate rotational force through hip positioning, body weight transfer, and chest pressure rather than relying on arm strength to crank the submission
-
Maintain heavy chest pressure throughout the entire finishing sequence to prevent the opponent from posturing, bridging, or creating escape space
-
Break defensive grips systematically before applying final rotational pressure rather than trying to power through clasped hands
-
Apply the finish with slow progressive pressure in a smooth arc motion, never jerking or spiking the arm behind the opponent’s back

Common Mistakes
-
Attempting to finish the Kimura using arm strength alone without creating proper body angle
- Consequence: Rapid energy depletion with low finishing percentage, especially against strong opponents who can resist arm-only pressure indefinitely
- Correction: Walk feet in arc toward opponent’s head to create perpendicular finishing angle, then use hip rotation and body weight to drive the finish rather than arm muscles
-
Releasing chest pressure during the finishing sequence to focus entirely on arm manipulation
- Consequence: Opponent creates escape space through bridging or hip movement, may roll out of submission or recover guard position entirely
- Correction: Maintain heavy chest pressure throughout the entire finishing sequence—the chest pin and the arm rotation must work simultaneously as a coordinated system
-
Attempting to power through the opponent’s clasped-hand defense rather than breaking grips systematically
- Consequence: Wasted energy and failed submission attempt, often resulting in loss of the Kimura grip entirely as fatigue sets in from fighting the defensive connection
- Correction: Use technique-based grip breaks including knee insertion, hand peeling, and stepover methods before applying rotational pressure to the freed arm
Playing as Defender
Key Principles
-
Defend early by recognizing angle creation and grip tightening before the attacker achieves the finishing position
-
Keep the trapped elbow pinned to your ribcage as your primary structural defense—the finish requires the elbow to be separated from the body
-
Use strong clasping grips (gable grip or S-grip) as your first defensive layer to prevent arm rotation behind your back
-
Create counter-movement through bridging toward the Kimura side to disrupt the attacker’s angle and pressure
-
Tap immediately when you feel sharp shoulder pain or when your hand has been driven past your hip line and you cannot stop the rotation
-
Never sacrifice neck exposure or back position while defending the Kimura—compound problems are worse than a single submission threat
Recognition Cues
-
Opponent’s figure-four grip tightens and their hands begin actively rotating your wrist away from your body rather than simply holding position
-
Opponent walks their feet in an arc toward your head while maintaining or increasing chest pressure, creating a perpendicular finishing angle
-
Opponent shifts weight forward and begins driving your trapped arm toward the mat behind your back with progressive force
-
Opponent’s hips lower and create downward rotational pressure on your shoulder that was not present during the control phase
Escape Paths
-
Straighten the trapped arm to break the figure-four grip configuration, then immediately pull the arm to your chest and recover half guard by inserting a knee shield between your body and the attacker
-
Bridge and roll toward the Kimura side while the attacker is focused on the finishing angle, using the momentum to create a scramble and recover to a neutral or guard position
-
Use your free arm to push the attacker’s hip away while shrimping in the opposite direction, creating enough space to extract your trapped arm or insert your legs for guard recovery
