Committee to Celebrate Japan's National Foundation
Nippon no Kenkoku o Iwau Kai
Founded in 1987, the Committee to Celebrate Japan's National Foundation (日本の建国を祝う会) has urged the government to sponsor ceremonies to celebrate National Foundation Day, February 11th.
During the Meiji period, it was recognized that, according to the Nihon Shoki (日本書紀), the first Japanese emperor, Jimmu, ascended to the throne on February 11th (converted from the original calendar system). They have organized ceremonies to mark the day throughout Japan every year.
In 2017, they published a resolution to call for constitutional revision at the ceremony at Meiji Jingū Hall. The resolution is reachable on the website of Nippon Kaigi/the Japan Conference, which has regularly worked with the committee.
