Gripping Techniques (Kumi kate)
The basic grips (Kumi kate) in judo are taken from shizentai (natural posture) and jigotai (defensive posture) by grasping the lapel of the opponent’s jacket with one hand and the sleeve with the other. Learn basics on gripping (PDF file), case study on grip domination, and how to develop grip strangth. Also watch this video.
Kuzushi, Tsukuri, and Applying a Throw (Kake)
Tsukuri is the entry and proper fitting of your body into the position taken just before the moment required for completion of your throwing technique.
Kake is the completing movement of your technique. Tsukuri and Kake can also be called technical principles of Judo.
Judo techniques work best when these three elements work together (Watch video).
