Tachi-ai (Initial Explosive Charge)

Crouch down behind the starting lines (Shikiri-sen), lowering the hips deeply into a broad squat.

Place both fists firmly on the clay surface, looking directly at the opponent.

Uncoil the legs explosively the microsecond the opponent touches down, launching the head, chest, and shoulders forward.

Drive forward using maximal leg extension, keeping the chin tucked and arms framed to strike or grab the opponent's belt.

Maintain forward momentum to push the opponent backward across the ring.
