Hou Raku or Horaku (Cave-In)
The name of this technique means a mountain that crumbles and falls. It is important that when avoiding the Ukes thrust, pull your left foot slightly back to close in the distance, and hug the Ukes arm tight into your armpit.
Both clasp both hands in Futen Goshin Gassho and bow to each other. Then both you and the Uke stand in Ichimonji no Kamae.
Stand in Hira no Kamae (Shizen no Kamae). The Uke draws the short sword and prepares to thrust into your back from behind.
As the Uke thrusts, shift to the left to evade and hug the Ukes arm under your right arm. Smash down to the Ukes hand with your left palm in a manner similar to Take-Ori to make the Uke drop the short sword.
Take hold of the Ukes wrist with the left hand and turn by pivoting clockwise on the right foot until you are parallel to the Uke to prepare for a Shuto.
Strike with Ura Shuto to the Ukes Kasumi (temple). This will put the Uke off-balance. Stamp onto the Ukes right foot with your right foot and grab the right shoulder with the right hand all at the same time.
Drop back to the left knee and pull the shoulder to throw the Uke face-down to the floor. This is done with a twisting motion. (Keep the Ukes hand raised).
Finish by standing up, still controlling the Ukes hand, and stamp on the Ukes head with your right foot.
Then return to Ichimonji no Kamae and Zanshin.
No one is useless in this world who lightens the burdens of another.
