Japan's two national flags

One is the national flag of Japan, also called the Japanese flag and the sun flag, as shown in the figure below. It is rectangular, and its length-width ratio is 3:2. The gap between the top and bottom of the circle is the same. The diameter of the circle is three-fifths of the length of the flag, and the center of the circle coincides with the center of the flag surface.

One is the rising sun flag, also called the Japanese flag, as shown in the figure below. It is a flag with red sun and rising light patterns, and it is a military flag adopted by the former Japanese army and the Japanese Self-Defense Force now.

The national flag of Japan is called Hinomaru, which comes from Japanese "Sun Maru" and literally means "Sun Circle". It is uncertain when the symbol of the sun circle was first used on flags and slogans. However, in the12nd century, samurai appeared. In the power struggle between Minamoto and Taira, samurai like to draw the sun circle on the folding fan (called Gunsen in Japanese). 15 and 16 During the Warring States Period in Japan, many military figures fought for spheres of influence, and the symbol of the sun flag was widely used as a military emblem.
