 The flag was especially used by samurai in the Kyushu region.Examples include the "Twelve-day legs" (変わり十二日足) of the Ryūzōji clan (1186-1607 CE) in Hizen Province and the Kusano clan (草野氏) in Chikugo Province and the "eight-day legs" (八つ日足紋) of the Kikuchi clan (1070-1554 CE) in Higo Province.There is a theory that in many parts of the Kyushu region, Hizen and Higo are related to what was called "the country of Japan (Hi)".
