Ruler and Sovereign of Japan, The Dynastic Emperors were identified by The Chrysanthemum Flower. In 1274, this symbol was incorporated into their own Personal Standard. The Flower (in Gold), featuring 16 petals, was placed in the Center of a Red Field in entirety. It was flown whenever The Emperor was in Residence (present in his Palace). The Emperor seldom was (and still is seen in Public). The Flag was unofficially adopted as the "National Flag" of Japan - as well as a Standard to identify Imperial Troops (Royal Infantry assets). After 1870, "The Rising Sun" Flag was adopted as The National Standard. The Chrysanthemum Flag is still used as the "Private Flag" of The Emperor.
