Kata gatame escape

Kata gatame escape is the judo-derived name for the bottom-position defence against the arm triangle — the strangulation in which the attacker’s shoulder and the opponent’s own arm close on the same side of the neck.

Etymology. Kata (肩) means “shoulder”; gatame (固め) means “hold” or “lock.” The term refers to both the strangulation configuration and, by extension, the position the defending player must escape. Japanese judo’s shime-waza (strangulation techniques) catalogue records the strangle under this name; in no-gi grappling the same configuration appears across MMA and submission-only rulesets. The escape’s name carries the parent technique forward, in the same pattern as juji gatame escape (armbar escape) and kesa gatame escape (scarf hold escape).

Mechanics. The escape’s priority is creating space between the attacker’s shoulder and the opponent’s neck before the bilateral compression closes. The defending player must either reposition the trapped arm to disrupt the figure-four closure or rotate their head toward the attacker’s chest to reduce the cervical compression angle — both require creating frame space before retrieving the threatened structure.

Cross-reference. English-speaking no-gi uses “arm triangle escape” or “head-and-arm escape.” Full mechanical coverage on Arm Triangle Escape.
