National Foundation Day (建国記念の日): A Patriotic Holiday for Japan

What is Japan’s 建国記念の日 (National Foundation Day)?

National Foundation Day (Kenkoku Kinen no Hi, 建国記念の日) is a public holiday which occurs annually on February 11th. If there is a day to be patriotic in Japan, it is National Foundation Day. As the name implies, National Foundation Day celebrates the foundation of Japan, and the ascension of Japan’s first emperor: Emperor Jimmu.

“Kenkoku Kinen no Hi” Explained

  • “Kenkoku” (建国) means “founding of a nation”
  • “Kinen” (記念) means “commemoration”
  • “no” (の) is the possessive particle (similar to “of”)
  • And “Hi”(日) means “day”.

Putting those together, we have the direct – albeit fairly messy – translation “founding of a nation, commemoration day”!

The Beginnings of the Holiday

The origins of National Foundation Day are bound tightly to the Meiji Restoration (Meiji Ishin, 明治維新) – a pivotal period in Japan’s history. Though this fact alone doesn’t make the holiday contentious, rather, it was the government’s intent for the holiday at that time…
Joys of modernization came with the Meiji Ishin, but so did massive political, social and economic changes – including the government’s attempt to connect Shintoism to the State. The national holiday “Empire Day” (Kigensetsu, 紀元節) was a direct product of these efforts, and from 1873 until 1945, Kigensetsu was used to commemorate the Emperor as the “one true ruler of Japan”. This holiday was deemed to be nationalistic in nature, so it was abolished in Japan’s Post-war Constitution. However, after numerous complaints, it was reinstated as National Foundation Day in 1966.

Why on the 11th of February?

The legend states that Emperor Jimmu ascended to the throne on the first day of the new year, but until 1873, Japan used the lunisolar calendar. It was during the modernization of Japan that the Meiji Emperor deemed it necessary to switch from the Lunisolar Calendar to the Gregorian Calendar which is used in Japan today. Hence, the first day of the Lunisolar Calendar corresponds to the 11th February in the Gregorian Calendar.

How is National Foundation Day Celebrated?

The original holiday, Kigensetsu, was once a big occasion in Japan. It was considered to be one of the four most famous holidays, and so the day was marked with celebrations and large parades. These days, however, the day is much more understated. During this time, many businesses and government buildings are closed. Although you will probably see more Japanese flags, there aren’t many overt displays of patriotism.
