Tori and Uke have taken hold of each other.  Tori changes his grip to a high collar grip with his fingers inside Uke's jacket.  Tori rapidly changes his position so he is behind Uke.  Tori has his right foot behind Uke's left ankle.

Tori keeps pressure on Uke all the time by pulling Uke's right arm with Tori sleeve grip across his body so as to have very close body contact between him and Uke.  Tori pins Uke's arm to his side between both there bodies.  Tori keeps a strong grip with his other hand on the collar grip so has to keep Uke's from changing his supporting leg. Tori swings his right leg up using his knee against the back of Uke's knee thus lifting Uke's leg of the ground.  Tori is still keeping a very tight grip on Uke's collar all the time.  Tori's hips should at the same time push Uke up as he is thrown.  Tori turns as they go backwards so as to try and finish of on top of Uke.
