STRANGLES/CHOKES (SHIME-WAZA)
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:
GROUP 1
-Compression of the veins in the neck which restricts the flow of blood and oxygen to the brain
GROUP 2
-Compression of the trachea
GROUP 3
-Compression of the chest and the lungs which prevents breathing.

HADAKA-JIME
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.
OKURI-ERI-JIME
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.
SANKAKU-JIME
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.
NAMI/GYAKU/KATA JUJI-JIME
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).
DO-JIME
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.
KATA TE-JIME
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.
