Japan's Emperor Hirohito announced the country's surrender on August 15, 1945, formally ending World War II in the Pacific. After atomic bombings of Hiroshima and Nagasaki and the Soviet Union's declaration of war, Japan's military leadership accepted the Allied demand for unconditional surrender, which was officially signed aboard the USS Missouri on September 2. ## Summary The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, ending the war. By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of Japan in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". ## Key facts - **Announcement date**: August 15, 1945 - **Formal surrender date**: September 2, 1945 - **Surrender location**: USS Missouri, Tokyo Bay - **Days between atomic bombings and surrender**: 9 days (Hiroshima August 6, Nagasaki August 9) - **Soviet entry into Pacific War**: August 8, 1945 (two days before announcement) - **Japanese casualties in WWII**: Approximately 2-3 million (military and civilian) - **U.S. occupation duration**: 1945-1952 (7 years) - **Supreme Allied Commander**: General Douglas MacArthur ## Timeline - **1945-07-26** - Potsdam Declaration issued Allied leaders (U.S., U.K., China) issue ultimatum demanding Japanese unconditional surrender; Japan initially ignores it. - **1945-08-06** - Hiroshima atomic bombing United States drops atomic bomb on Hiroshima, killing approximately 70,000 people instantly. - **1945-08-08** - Soviet Union declares war Soviet Union enters the Pacific War against Japan, invading Manchuria and violating the Soviet-Japanese neutrality pact. - **1945-08-09** - Nagasaki atomic bombing United States drops atomic bomb on Nagasaki, killing approximately 40,000 people. - **1945-08-10** - Japanese government seeks surrender terms Japan's Supreme War Council meets; government begins exploring conditional surrender through Swiss intermediaries. - **1945-08-14** - Cabinet approves unconditional surrender Japanese government, urged by Emperor Hirohito, formally decides to accept Potsdam Declaration terms. - **1945-08-15** - Hirohito announces surrender on radio Emperor Hirohito's recorded voice broadcast nationally in Japan (Gyokuon Hōsō).
