Shime-Waza is possibly the most difficult branch of Judo to master. Because of the precision required in the execution of many of the techniques, few judoka will ever attain a complete mastery of the art of Shime-Waza.
The 12 standard Kodokan techniques of Shime-Waza can be categorised by one or more of three methods of application:
-Compression of the veins in the neck which restricts the flow of blood and oxygen to the brain
-Compression of the trachea
-Compression of the chest and the lungs which prevents breathing.

Naked-Choke (Group 1 (shown above) or 2)
A self-defence and military favourite, Hadaka-Jime features in one form or another in most martial arts. This choke does not require a Judo-Suit (Judogi) for it to be applied, and so is known as 'naked'. It can be performed as a straight attack to the trachea, or to the side where it becomes a strangle, between forearm and bicep/shoulder.
Triangle-Choke (Group 1)
A type of 'figure-four' chokehold which strangles the opponent by encircling the opponent's neck and one arm using either arms or (more commonly) the legs in a configuration similar to the shape of a triangle. The technique is a type of lateral vascular restraint that constricts the blood flow from the carotid arteries to the brain.
