TORI and UKE stand in front of each other, Tori grips with both hands on the reverse of UKE.
UKE pushes TORI strongly backwards; TORI puts his right leg behind the right leg of UKE (see Judo throw O soto otoshi), so that both knees are in contact, accepts the pressure to the rear to and is falling backwards, here he pulls UKE with his right arm, while his left arm pushes UKE to the right; TORI's right shoulder is always in front of the right shoulder of UKE. At the same time TORI hooked his left foot before the instep and the side of the back of the right ankle (Achilles tendon) of UKE.
The moment while TORI reaches the ground; a little before UKE (Sutemi principle), he turns toward its right side. With his left leg as a fulcrum TORI interspersed with a turn to the right before UKE, which lies on the abdomen; TORI draws with his right arm to the back, with his right lower leg still, as in the state, in the right knee of UKE. TORI attacks with his left hand UKE's right instep and prevents the lower leg in the direction of UKE's thigh. The lever has an immediate effect on UKE's knee.
COMMENT: The final position and the lever is in line with the leg lever Hiza hisigi. Important in this technique is that TORI ensures that UKE "flat" on his stomach comes to rest.
