Koryu Uchinadi Shime-waza

Chokes and strangulations (締め技, shime-waza) enable the one applying the choke to force the adversary into unconsciousness and even death. Strangulation cuts off the blood supply to the brain via compression on the sides of the neck, while a choke blocks the airway from the front of the neck. The terms are frequently interchangeable in common usage, and a formal differentiation is not made by most jūdōka. In competition, the jūdōka wins if the opponent submits or becomes unconscious. A strangle, once properly locked in, can render an opponent unconscious in only a few seconds, but normally causes no injury.
