The History of Foundation Day?

Foundation Day, known as Kenkoku Kinen no Hi (建国記念の日), is one of Japan's most historically symbolic holidays, celebrated each year on February 11. It commemorates the founding of the Japanese nation and the legendary ascension of Emperor Jimmu, Japan's first emperor, to the throne in 660 BCE, an event described in Japan's oldest chronicles, the Kojiki and Nihon Shoki.

The holiday's origins date back to 1872, during the Meiji era, when it was first established as Kigensetsu (紀元節), or "Empire Day". It was meant to promote national unity and respect for the emperor, reflecting Japan's efforts to modernize while emphasizing imperial traditions.

After World War II, Kigensetsu was abolished by the Allied occupation authorities in 1948 due to its association with militarism and nationalism. However, in 1966, the holiday was reinstated under the new name National Foundation Day, with a more neutral, reflective meaning, celebrating Japan's founding and fostering love for the country, rather than imperial power.

Today, Foundation Day is observed quietly across Japan. Citizens raise the national flag, attend commemorative ceremonies, and reflect on Japan's long history, cultural identity, and hopes for peace and prosperity.
