The Rising Sun Flag is a military flag used by the Imperial Japanese Army and Navy from the late 19th century until the end of World War II. It features a red sun with 16 rays extending outward on a white background. The flag symbolizes Japan's imperial ambitions and is often associated with Japan's militaristic past. Today, the Rising Sun Flag is a controversial symbol, particularly in countries that suffered under Japanese occupation during the war. It is viewed by some as a symbol of nationalism and militarism, while others see it as a representation of Japan's cultural heritage.
