The Japanese flag is called the sun flag, and the red circle represents the sun. In ancient times, it was used as the flag of the shrine, and it was used as the flag of Japanese ships from16th century and as the national flag from 1870. The standard length-width ratio of the national flag is 2:3, the diameter of the Japanese national emblem is 3/5 of the width, and the Japanese national emblem is in the middle of the flag. Because Japan has not determined the national emblem, it sometimes uses the chrysanthemum or phoenix tree pattern with petals of 16, that is, the royal national emblem, instead of the national emblem. The lyrics of the Japanese national anthem "King's Landing" were originally included in the Collection of Ancient and Modern Harmony Songs, and the author is unknown. This song was written by Lin Guangshou, a musician from Miyagi Province in the Meiji era, and was confirmed as the national anthem in 1893. The main idea of the lyrics is: the monarch reigns in the world and lasts forever, just like a small stone forming a rock with moss on it.

National flower and bird

The Japanese have considered cherry blossoms as the national flower of Japan since ancient times. Cherry blossoms have also appeared in Japanese mythology. When withered, it is crisp and neat, and people associate it with the samurai's outlook on life. Cherry blossoms are widely planted all over Japan, and it is a great pleasure for the Japanese to hold a banquet under the blooming cherry trees. In addition, because there are chrysanthemums on the royal family emblem, chrysanthemums are also regarded as the national flowers of Japan. The pheasant, which is often mentioned in Japanese myths and legends, was designated as the national bird in 1947. Pheasant is a unique bird in Japan, and there are obvious differences in size and color between male and female. The face of the male pheasant is red, the neck, chest and abdomen are dark green, the back is purplish, the tail is long and there are many black ribbon feathers. The female pheasant is light brown with black stripes and a short tail.
