Constitution Memorial Day

Constitution Memorial Day, or Kenpō Kinenbi, is observed on May 3 to mark the enactment of Japan's postwar constitution in 1947. After World War II, Japan adopted a new constitution to replace the Meiji Constitution. The new document emphasized democratic principles, the sovereignty of the people, and a strong commitment to peace. One of its most well-known features is Article 9, which renounces war and prohibits the maintenance of armed forces for warfare.

The holiday was established to give citizens an opportunity to reflect on the values of peace, democracy, and human rights. It is part of Golden Week, a series of national holidays in early May. Constitution Memorial Day does not include grand celebrations, but it holds deep meaning in the nation's political and social history. It marks a turning point when Japan shifted from imperial rule to a democratic system, shaping the country's postwar identity and commitment to peaceful governance.
