Hadaka jime escape

Hadaka jime escape is the judo name for the defence against the rear naked choke — the strangulation applied from behind in which the attacker’s arm closes around the opponent’s neck without a clothing grip.

Etymology. Hadaka (裸) means “naked” or “bare” — referring to the absence of a clothing grip, not to the attacker’s state — and jime (絞) means “strangle.” The technique sits in Kodokan judo’s shime-waza (strangulation techniques) catalogue. Because the parent technique requires no clothing grip, hadaka jime translates one-to-one into no-gi grappling without modification; the escape term carries the same position-neutral specification. The judo name remains the primary search term in judo and judo-influenced submission curricula even where the BJJ “rear naked choke” terminology has otherwise predominated.

Mechanics. The escape’s priority is preventing the bilateral compression on the carotid arteries from closing before consciousness is compromised. The defending player must hand-fight the choking arm at the wrist or elbow before the closed-loop figure completes, while tucking the chin and rotating toward the open side of the attacker’s body to break the strangle before structural failure.

Cross-reference. Portuguese-language BJJ uses mata leão escape; English-speaking no-gi uses “rear naked choke escape” or “RNC escape.” Full mechanical coverage on Rear Naked Choke Escape.
