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.
Sliding-Collar-Choke (Group 1)
Okuri-Eri-Jime uses the opponent's own collar to strangle. Frequently used in Randori and competition, there are many variations.
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.
Normal-Cross/Reverse-Cross/Half-Cross Choke (Group 1 - if done properly!)
This series of strangles are similar to each other in principle and differ mainly in the placement of the hands (palms up or down).
Trunk Constriction (Group 3)
Although one of the original 12 Shime-Waza listed among the official techniques of Kano's Kodokan Judo, and therefore worthy of study, Do-Jime is dangerous, and a prohibited technique (Kinshi-Waza) in modern judo competition.
Single-Hand Choke (Group 1 or 2 (as shown above))
An effective strangle using just one hand (Kata-Te): its efficacy relies on the use of the legs and the other arm to restrict the opponent's freedom of movement.
