Glossary of Judo terminology
"Belt front" refers to the front part of the belt. Although Judo rules impose a penalty for grasping the belt for 6 seconds or longer, the belt grasp is permitted when executing a Waza such as the Obi-otoshi (Belt drop), etc., to throw the opponent. In these Waza, Tori (Player executing technique) grasps the front part of Uke (Player receiving opponent's attack) belt and pulls him forward until Uke (Player receiving opponent's attack) body is snugly against him. In this posture, Tori (Player executing technique) can maintain his balance while effectively using his force to perform the throw.
The belt front may also be grasped in preparation for a Katame-waza (Grappling techniques).
