Sode tsuri komi goshi
Toshihiko koga

(sleeve lifting pulling hip throw)

Againast a leading left hand koga takes an underside sleeve grip with his right hand and takes a massive step through with his right leg  
 
now he starts to drive his hand downwards and underneath his body. His left arm starts to scoop backwards increasing his momentum into the turn.
To turn his opponent onto his back Koga fully commits his weight into the throw, whipping his right arm across his body and throwing his left arm back against his opponents legs. even though his opponent gets his free hand to the mat the momentum of the turn is sufficient to take him over.  
He keeps driving his shoulder down, launching off his toes to put his opponent onto his back.  
  Koga has spun through a full 360 degrees during the course of the technique.
