The way in which Kyudo is performed has remained almost unchanged since the 15th century. There have been many schools, among them Ogaswara and Heki Ryu. The main concern of the Ogasawara Ryu was how to dress and how to move. During the Tokugawa Period in the first part of the 17th century the 3rd Shogun ordered the Ogasawara Ryu to define their own ceremony. The style of this school was developed from Yabusame (shooting from horseback) and it has remained unchanged up to the present. The All Nippon Kyudo Federation (A.N.K.F.) combined elements of Ogasawara and Honda.
