Tsuru Ashi Dachi is a stance in Kyokushin karate. It translates to 'Crane Leg Stance.' In this stance, one leg is raised and bent so that its foot touches the knee of the base leg, resembling the stance of a crane. The exact form of contact between the foot and the knee depends on the style or even on the particular version of the kata where this stance is used. It provides stability and balance while allowing for quick movement and agility.
