SAFETY: Kimura from High Mount targets the Shoulder joint, rotator cuff, and shoulder capsule. Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis). Release immediately upon tap.
The Kimura from High Mount exploits the elevated knee positioning to trap and isolate the defender’s arm with a figure-four grip, then rotate the shoulder joint past its natural range of motion. High mount provides distinct advantages over standard mount or side control Kimura attacks: the top player’s weight compresses the defender’s upper chest, severely limiting their ability to straighten the trapped arm or roll to escape. The defender’s elbows are naturally pushed higher by the attacker’s knees, making wrist capture significantly easier than from lower mount variations.
The mechanics differ from other Kimura positions because the attacker works from directly above rather than beside the opponent. This top-down angle allows gravity to assist the finishing rotation and makes the common arm-straightening defense far less effective. The defender cannot generate sufficient leverage to extend their elbow when pinned beneath the attacker’s elevated hips. The attacker can also switch seamlessly between Kimura and Americana based on how the defender positions their hand, creating a two-way shoulder lock dilemma.
In competition, the Kimura from High Mount frequently appears as part of submission chains from the mount. When the defender protects their neck from collar chokes or hides their arms from armbar setups, their bent-arm defensive posture exposes the wrist for Kimura grip capture. The Kimura threat forces arm extension, which opens armbar and triangle opportunities, making it a cornerstone technique in systematic mount attack sequences.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis) | High | 3-9 months with potential surgery requirement |
| Shoulder capsule damage and dislocation | CRITICAL | 6-12 months, may require surgical repair |
| Labral tear (glenoid labrum) | High | 4-8 months, often requires arthroscopic surgery |
| Bicep tendon strain or rupture | Medium | 6-12 weeks for strain, 3-6 months for rupture |
Application Speed: SLOW and progressive - 3-5 seconds minimum in training, allowing partner time to recognize danger and tap
Tap Signals:
- Verbal tap (saying ‘tap’ or making any verbal distress sound)
- Physical hand tap (multiple taps with free hand)
- Physical foot tap (multiple taps with either foot)
- Any distress signal including screaming or unusual sounds
Release Protocol:
- Immediately stop all rotational pressure the instant tap is felt or heard
- Return the arm toward neutral position (externally rotate back to starting position)
- Release the figure-four grip completely
- Allow partner to self-assess shoulder mobility before continuing
- Never release suddenly or allow arm to spring back forcefully
Training Restrictions:
- Never spike or jerk the submission - rotation must be smooth and controlled
- Never use competition speed or surprise attacks in training
- Always ensure partner has at least one hand free to tap
- Do not apply while partner is in awkward body position that prevents tapping
- Never combine with weight pressure that restricts breathing while finishing
- Respect immediate taps without testing partner’s pain tolerance

Playing as Attacker
Key Principles
-
Maintain forward hip pressure on the defender’s upper chest throughout the entire attack sequence to prevent bridging escapes
-
Isolate the target arm before committing to the figure-four grip to avoid losing mount position during the transition
-
Keep elbows squeezed tight together after securing the figure-four to eliminate slack and prevent arm extraction
-
Use your entire body structure to drive the rotation rather than relying on arm strength alone
-
Pin the defender’s elbow to the mat as the fulcrum point before initiating rotational pressure
-
Stay prepared to switch between Kimura and Americana based on the direction the defender moves their forearm
-
Apply finishing pressure progressively to allow training partners time to tap safely
Execution Steps
-
Identify and isolate the target arm: From high mount, select the arm that is most exposed or least protected. Swim your near-side hand un…
-
Capture the wrist with a C-grip: Secure a firm C-grip on the defender’s wrist with your same-side hand, pulling their hand away from …
-
Thread the figure-four grip: Slide your opposite hand under the defender’s trapped arm at the tricep level and grip your own wris…
-
Pin the elbow to the mat as the fulcrum: Drive the defender’s elbow toward the mat beside their head using steady downward pressure through y…
-
Adjust hip position for optimal leverage angle: Shift your hips slightly toward the trapped arm side, angling your body to maximize rotational lever…
-
Apply controlled rotational pressure toward the mat: Begin rotating the defender’s wrist toward the mat behind their back using a smooth, progressive arc…

Complete the finish with structural pressure: Continue the controlled rotation until the opponent taps or you reach the natural endpoint of should…
Common Mistakes
-
Sitting upright to attack the Kimura instead of maintaining forward chest pressure
- Consequence: Allows the defender to bridge effectively and escape mount entirely, losing the dominant position
- Correction: Keep your chest driving forward into the defender’s upper body throughout the entire Kimura sequence, only shifting your weight laterally for finishing angle, never backward
-
Attempting the figure-four grip before properly isolating the arm from the body
- Consequence: The defender clasps their hands together or grabs their own gi, creating a strong defensive connection that is difficult to break once established
- Correction: Fully separate the target arm from the defender’s body using swim moves, frame breaks, or knee wedges before committing to the figure-four grip
-
Leaving elbows loose in the figure-four grip with excessive slack
- Consequence: The defender extracts their arm through the gap between your elbows, escaping the submission entirely and potentially recovering defensive position
- Correction: Squeeze your elbows together tightly after completing the figure-four, maintaining constant inward pressure to eliminate any space for arm withdrawal
Playing as Defender
Key Principles
-
Keep elbows glued to your ribs and hands near your chin to prevent arm isolation and wrist capture from the start
-
Recognize the Kimura setup before the figure-four grip is completed, when defensive options are still available
-
Connect your hands by clasping or gripping your own clothing the instant you feel wrist control being established
-
Use the attacker’s weight shift during the Kimura attempt as a window for bridge and roll escapes
-
Prioritize preventing the elbow from being pinned to the mat, as this is the critical fulcrum point for the finish
-
Stay calm and breathe steadily under pressure rather than panicking and making explosive but poorly timed movements
Recognition Cues
-
Attacker’s near-side hand begins swimming under your elbow or reaching for your wrist while in high mount
-
Attacker shifts their weight laterally toward one side while maintaining chest pressure, indicating they are angling for the figure-four
-
You feel your elbow being lifted or pried away from your ribs by the attacker’s knee or hand
-
Attacker abandons a choke attempt and immediately reaches for your arm, signaling a transition to shoulder lock attack
Escape Paths
-
Bridge and roll toward the Kimura side when the attacker shifts weight laterally for the finish, using their commitment against them to escape mount
-
Hip escape when the attacker’s knee lifts away from your armpit during the Kimura setup, inserting your knee to recover half guard before the figure-four is completed
