The primary color of the flag of Japan is white, featuring a bold red circle in the center that represents the sun. This simple yet striking design is known as the "Nisshoki" or "Hinomaru." The red circle symbolizes Japan's position as the "Land of the Rising Sun," referencing the country's name in Japanese, which translates to "sun origin." The flag has deep historical and cultural significance, with its design evolving over centuries before being officially adopted in 1854. It is a source of national pride, often displayed during public events and international representations.
