Jo technique: Thrust against an opponent who is behind.
Commence in basic left posture as for the first Jo suburi. Grasp the top of the Jo with your right hand (thumb pointing upwards). Lift the Jo placing it along the underside of your left forearm while sliding your left foot back beside your right. Step back with your left foot, thrusting the Jo straight to your rear and turning your body to your left as you do this.
