Tai sabaki refers to the complete movement of the body while wielding a naginata. And it is through ashi-sabaki, footwork, in which this movement is initiated. Below are the primary methods of moving one's feet, with brief descriptions and diagrams of the movements. There are also small video clips showing beginners (ikkyu and under) using the footwork. Apple Quicktime required.
Okuri-ashi: The footwork used when striking, and for moving in all directions.
Ayumi-ashi: Footwork used for going frontward and backward. When moving forward start with the right foot first and move four steps forward. When moving backward, start with the left foot first and take four steps back.
Tsugi-ashi: Footwork used when striking from distance or when you want to reduce the ma ai quickly.
Hiraki-ashi: Footwork used when avoiding a strike or responding. When moving to the left, step with the left foot and follow with your right. It can also be used for moving to the right with opposite stepping order and for changing directions.
Fumikae-ashi: Footwork used for changing the direction that the body is facing on the spot when striking or counter-attacking.
