hadakajime

Hadaka-jime, sometimes romanized as hadakajime, is a term used in Japanese martial arts, most notably judo and Brazilian Jiu-Jitsu, to describe a naked or bare-neck choke. The name comes from hadaka meaning naked and jime meaning choke or strangle. It is classified as a shime-waza, a group of choking techniques, in the Kodokan system.

Description: Hadaka-jime is performed by encircling the opponent's neck with the arms and applying pressure to impede the flow of blood to the brain via the carotid arteries. Unlike chokes that rely on clothing, it does not use the opponent's gi or belt. The choke is capable of stopping the opponent if held, which is why training emphasizes tapping to indicate submission and safety breaks according to sport rules.

Usage and history: The technique is part of the traditional judo curriculum and has been adopted widely in Brazilian Jiu-Jitsu and other grappling arts. It is valued for its effectiveness from multiple positions, but it carries significant risk of injury and must be practiced under qualified supervision with proper safety protocols.

Variations and terminology: The term has several spellings, including hadaka-jime and hadakajime, and it appears in various grappling rule sets. It belongs to the broader family of front-strangle techniques alongside other shime-waza.
