National Foundation Day (Kenkoku Kinen no Hi / 建国記念の日) is a Japanese national holiday celebrated annually on February 11th. This holiday commemorates the legendary founding of Japan and the ascension of its first emperor, Emperor Jimmu, in 660 BCE according to traditional mythology.
What is National Foundation Day?

National Foundation Day marks the establishment of the Japanese nation and celebrates the country’s founding. The holiday is based on the ancient chronicles Kojiki 和 Nihon Shoki, which describe Emperor Jimmu’s ascension to the throne on the first day of the first month of the traditional Japanese calendar, which corresponds to February 11th in the Gregorian calendar.
While the historical accuracy of this exact date is debated by scholars, the day serves as an important occasion for Japanese citizens to reflect on their nation’s history, culture, and identity.
History of the Holiday

The holiday has a complex history that reflects Japan’s political transformations:
National Foundation Day was originally established as Kigensetsu (Empire Day) in 1872 during the Meiji era. After World War II, the holiday was abolished in 1948 during the Allied occupation due to its association with Japanese militarism and nationalism. The holiday was reinstated in 1966 under its current name, National Foundation Day, as a more politically neutral celebration of Japan’s founding rather than imperial mythology.
