Constitution Memorial Day (Japanese: 憲法記念日, Kenpō Kinen-bi) is a national holiday in Japan. It takes place on May 3 in celebration of the promulgation of the 1947 Constitution of Japan. It is a part of the collection of holidays known as Golden Week.[1]\n\nA holiday since the current Japanese constitution came into effect on May 3, 1947, this is the only day of the year that the National Diet Building (国会議事堂, kokkai-gijidō) is open to the public.[2] Being a day that draws its significance from the Japanese constitution, Constitution Memorial Day is often chosen as a day to reflect on the meaning of democracy and Japanese government. For instance, in 2003, a number of newspapers featured editorials regarding the constitution's embattled Article 9.[3]
