The National Anthem of Japan, known as "Kimigayo," is one of the world's oldest anthems, with lyrics dating back to the Heian period (794-1185). The music was composed in 1880, and the anthem is characterized by its short and simple melody. The lyrics express wishes for the longevity and prosperity of the emperor, symbolizing the unity and strength of the nation. "Kimigayo" is officially recognized as the national anthem of Japan, although it does not have a formal law governing its use. The anthem is often played at national events, including sports competitions and ceremonies, reflecting Japan's cultural heritage and national pride.
