[edit] Tsuki Jodan Gaeshi

Jo technique: Two combination movement (mid). Commence in hidari Tsuki No Kamae. Swing back with your right hand to perform Choku Tsuki (first Jo suburi), sliding your feet forwards. Move backwards and to the right, still in hidari hanmi, bringing the Jo up to protect your head. Slide your right hand up to your left and rotate the Jo over your head, in your right hand, to a striking position in preparation for Shomen Uchi strike (right wrist twists, left hand grasps base of Jo). The strike is performed by swinging the Jo in an arc over your head and down onto your opponent as you step forwards with your right foot.
