The national flag of Japan is officially named the Nisshoki, which means the sun-mark flag. This name refers to its appearance, which is a crimson circle set on a white background. A proper Japanese flag must have a height to length ratio of 2 to 3. Additionally, the circle must be placed precisely in the center of the white field and measure three-fifths of the length of the flag.
The largest Japanese flag on record is located in the Shimane Prefecture, where it flies outside of the Izumo Shrine. Its measurements are 44.6 feet by 29.5 feet and is hung at an elevation of 154 feet.
