Sensu to Tsukimaru Postcard

[Ogimaru] Senmon. It is also called Satake-ogi. This name was written by Yorisuke NUMATA in "Nihon Monshogaku" . By the way, in "Nihon no Monsho" edited by Kosaku ITO, it is called 'Tsuki no Maru Sensu.' In addition, "Heian Monkan" and "Monten" are referred to as 'Hinomaru Ogi.' It is believed that the way to 'Hinomaru' was established by Satake's 'Ogi' was to represent the moon with five bones and a round shape. At that time, it was legal to make a moon with gold on the ground of Omotebeni and silver on the back...This indicated a red 'day' on the black ground in later years. What the Satake family used was, in other words, a white circle was used on a red background with a flag crest on the back, and even a circle was used on a family crest, but it was called 'Tsukinomaru' (The Moon Circle) (by Kenichi TAKAHASHI, "Daimyo-ke no Kamon" [Family Crest])
