Sumi Otoshi – Corner Drop Demo
From a right natural posture (migi shizentai), withdraw your right foot and draw out Uke’s left foot. While bending your knees and lowering your hips, advance your left foot outside his right foot. At the same time, with your right hand, push him strongly to migi ushiro sumi – supplement this movement by a pull with your left hand and “float” Uke towards migi ushiro sumi.
Now Uke is tilted towards migi ushiro sumi and his left leg should “float” up into the air. A strong PUSH with the right hand and PULL with the left hand will now be sufficient enough to throw him. The ‘steering wheel’ motion of your hands will be in a relatively small space, just in front of your right shoulder with your left hand at about your right elbow when executing the throw.
Drive strongly with your hips toward Uke’s migi ushiro sumi with your legs and your right hand. Your left hand should remain locked at your right side. Uke will fall onto his back in front of you with both of his legs in the air.
