The dominant color of the flag of Japan is white, featuring a red circle in the center. The white background symbolizes purity and honesty, while the red circle represents the sun, which holds deep cultural and historical significance in Japan. Often referred to as the "Nisshoki" or "Hinomaru," the flag was officially adopted in 1854, although its designs have been used since the 7th century. This simple yet striking combination of colors is recognized worldwide and epitomizes Japan's identity, linking back to its nickname, "The Land of the Rising Sun."
