Jūken Dōri – Irimi Nage – 90° Palm on Chin Variation

Uke thrusts with a Jūken (bayonet). Tori enters to the outside and makes contact with the weapon using his rear hand, redirecting it downward. At the same time, he steps in with his lead foot at a perpendicular 90° angle to the line of attack, delivering a palm strike to Uke’s chin as he steps. This tilts Uke’s head backward, breaking his spinal alignment and posture, and causes him to fall.
