The Utsuri-goshi (Hip shift) Waza is used as a counter to an attempted Koshi waza (Hip techniques).
When the opponent attempts a Koshi waza (Hip techniques), Tori (Player executing technique) must release his Hiki-te (Pulling hand) grip, wrap his arm all the way around the opponent’s waist, and grasp the opposite side.
Tori also lowers his hips and bends his knees, positioning them in the hollows behind the opponent's knees has spun around to bring the opponent against his back), thereby preventing the opponent from effectively using his knees' spring force.
Then, in the instant that the opponent attempts to move into a better posture, Tori destabilizes the opponent's balance toward the front, and, with an arm wrapped around the opponent's waist, shifts him onto the hip and throws him in the forward direction.
While lifting the opponent in a hug-like grasp, the opponent's knees are bent and his stance is low. Then, while executing the throw, Tori straightens his knees, using their spring force to complete the throw.
