History
Constitution Memorial Day marks the day Japan’s new constitution came into effect on May 3, 1947. After World War II and Japan’s surrender in 1945, U.S. General Douglas MacArthur collaborated with Japanese officials to draft a new constitution. This “Peace Constitution” replaced the Meiji Constitution, establishing democratic governance and renouncing war. Initially, November 3rd was proposed for the holiday (the date of its promulgation), but May 3rd was chosen instead to avoid overlap with war crime trials that began on the same day.
