This category focuses on Japan's national flag, widely known as the Hinomaru ("circle of the sun") and officially called the Nisshōki ("flag of the sun"). Its design places a red disc at the center of a white field, referring to Japan's association with the rising sun. The stark contrast and uncomplicated geometry make the emblem distinctive. Under Japan's 1999 flag law, the flag's proportions are 2:3, and the disc's diameter is three-fifths of the flag's height. The design has a much longer history of use than its formal legal designation, and remains the clearest visual symbol of Japan among national flags.
