There are two national badges of Japan. One is chrysanthemum emblem, which is the emblem of the emperor and the royal family of Japan; The other is the Tonghua badge, which is the badge of the Japanese government. The Japanese royal chrysanthemum badge is a yellow or orange chrysanthemum pattern, with the edges outlined by black or red lines. The chrysanthemums in the pattern are divided into two layers, with 16 petals at the top and bottom. The two petals are staggered with each other, and the lower petals are exposed from the gap between the upper and lower petals.

    In the Meiji era, except for the king of Japan, others were forbidden to use 16 petal chrysanthemum badges; Therefore, the badges of other members of the royal family have been modified on this basis. For example, in 1333, Emperor Houmin tried to get rid of the shogunate and was exiled after failure. He later chose a 17 petal chrysanthemum badge to distinguish the 16 petal chrysanthemum badge used by Emperor houguang of the Northern Dynasty. Other members of the royal family generally choose a heavy 14 petal chrysanthemum badge; A 16 petal chrysanthemum badge is used in the brooch, medal, passport and other objects showing the rule of the emperor.

    In addition, the Royal chrysanthemum emblem logo will appear on the shrines of Shintoism in Japan, and the chrysanthemum pattern in these signs is usually combined with some elements of Shintoism. In fact, the Japanese royal badge was not a chrysanthemum badge at the beginning; Before that, as early as the 12th century, the Japanese royal family used another pattern as its badge, that is, the Paulownia badge. The lower part of the badge pattern is the root of paulownia tree, and there are three paulownia trees on the upper part. There are 5, 7 and 5 Paulownia flowers on the tree respectively. Therefore, it is also called 5 ‐ 7 Paulownia badge.

    The Paulownia badge was first used by Chen Chen's family as the overhead feather of the clan; After the Meiji Restoration, the Paulownia emblem, as a symbol of the Japanese government, appeared in official documents such as the government and cabinet. I don't know that there is only one style of Paulownia emblem in Japan; In fact, there are 140 different versions of Paulownia badges, 70% of which are 5-3 Paulownia badges, that is, there are 3, 5 and 3 Paulownia flowers on the three paulownia trees respectively.
