What are the two national flags of Japan?

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 background of the Japanese flag

Japan's national flag is called "Rizhangqi", and its name comes from Japanese "Rimaru", which literally means "Sun Round Wheel". Since ancient times, the Japanese nation has had a soft spot for the glorious image of the sun, especially for the pattern of the "sun". They worship the mythical "God of the sky" (ぁまてらすぉぉみかみかみかみみかみ) as "Sun God" and call their country.
