Katame-no-kata

Katame no Kata (固の形) is one of the two Randori-no-kata (乱取りの形) of Kodokan Judo. It is intended as an illustration of the various concepts of katame-waza (固技) that exist in judo, and is used both as a training method and as a demonstration of understanding.

History
The katame-no-kata was developed by Jigoro Kano as a method of illustrating principles of grappling to allow students to more effectively apply them in randori. Initially, the kata consisted of ten techniques. These were subsequently appended, bringing the number to fifteen.

The Katame no Kata was developed at the Kodokan between 1884 and 1887 following the development of the Nage no Kata. It is composed of three groups of grappling techniques each with five representative techniques. Your goal is to acquire the methods of controlling your opponent in your practice of Katame No Kata.
