On May 3, 1947, Japan's postwar constitution goes into effect. The progressive constitution granted universal suffrage, stripped Emperor Hirohito of all but symbolic power, stipulated a bill of rights, abolished peerage, and outlawed Japan's right to make war.The Constitution is best known for Article 9, by which Japan renounces its right to wage war; and to a lesser extent, the provision for de jure popular sovereignty in conjunction with the monarchy.
