Japan was placed under the nominal international control of the Allies, and in actuality was ruled by one person, through the Supreme Commander, Gen. [[Douglas MacArthur]]. U.S. objectives were to ensure that Japan would become a peaceful nation and to establish democratic self-government supported by the freely expressed will of the people. Political, economic, and social reforms were introduced, such as a freely elected Japanese Diet (legislature) and universal adult suffrage. The country's new constitution took effect in May 1947. The United States and 45 other Allied nations signed the Treaty of Peace with Japan in September 1951 and Japan regained full sovereignty in April 1952. The 1972 reversion of Okinawa completed the U.S. return of control of these islands to Japan. | Japan was placed under the nominal international control of the Allies, and in actuality was ruled by one person, through the Supreme Commander, Gen.
