Kyan learned Chintō from Matsumora Kōsaku 松茂良 興作. The Matsumora version has an embusen (the line that the body follows) at a 45° angle, while Matsumura's embusen was straight, and the angled version fit Kyan's slightness and agility well. This Chintō is another Tomari-te kata. Kyan incorporated that 45° angle into many of his fighting techniques.
