Instrument of Surrender (1945) was the formal document that effected the capitulation of the Empire of Japan to the Allies of World War II on 2 September 1945 aboard the USS Missouri (BB-63) in Tokyo Bay. The surrender followed the Atomic bombings of Hiroshima and Nagasaki, the Soviet–Japanese War, and protracted diplomatic and military consultations at venues including the Potsdam Conference, Cairo Conference, and Yalta Conference. The document established the legal framework for occupation under leaders such as General Douglas MacArthur and shaped postwar arrangements involving entities like the United Nations and the International Military Tribunal for the Far East.

Background

The surrender emerged from campaigns and conferences that linked events such as the Battle of Okinawa, Battle of Iwo Jima, and the Battle of Leyte Gulf with strategic decisions made by figures including Franklin D. Roosevelt, Harry S. Truman, Winston Churchill, Joseph Stalin, and Chiang Kai-shek. The Declaration on the surrender of Japan at Potsdam Conference (the Potsdam Declaration) called for unconditional surrender, a principle debated in forums involving delegations from United Kingdom, United States, China, and later referenced by representatives of the Soviet Union. The Manhattan Project developments that produced Little Boy and Fat Man and the August 1945 Soviet invasion of Manchuria influenced Emperor Shōwa (Hirohito) and cabinets led by politicians such as Kantarō Suzuki, Prince Higashikuni, and Suzuki Kantarō toward acceptance. Legal and diplomatic contexts involved prior instruments like the Treaty of Versailles and institutions such as the League of Nations that shaped concepts used by the United Nations.

Drafting drew on precedents from instruments signed after conflicts like the Treaty of San Francisco (1951) and protocols used at the Capitulation of Japan discussions. Delegations included military legal advisers and representatives from the Supreme Commander for the Allied Powers (SCAP), the Combined Chiefs of Staff, and national delegations from United States Navy, Royal Navy, Soviet Navy, Royal Australian Navy, and Royal Canadian Navy. Key negotiators and military officers provided input, including Douglas MacArthur, Chester W. Nimitz, Arthur Percival, Arthur Tedder, Bernard Montgomery, Georgy Zhukov, and legal minds familiar with documents like the Instrument of Surrender (Germany) and the Instrument of Surrender (Italy). Drafts referenced the Yalta Conference terms, Allied statements by Harry S. Truman and Winston Churchill, and consultations with diplomats from Republic of China led by Chiang Kai-shek. Language was settled to address issues raised by commanders such as Isoroku Yamamoto (posthumously referenced) and planners from Pacific Fleet and the 26th Bomber Command.

The ceremony was held on the deck of USS Missouri (BB-63), anchored in Tokyo Bay, with representatives from major Allied powers including delegations from United States, United Kingdom, Soviet Union, China, Australia, Canada, France, Netherlands, New Zealand, India, and Philippines. Presiding officer Douglas MacArthur accepted the surrender on behalf of the Allies of World War II, with signatures made by Chester W. Nimitz for the United States Navy, Arthur Percival for the British Commonwealth, Yevgeny Ukhtomsky and Soviet representatives for the Soviet Union, and representatives from Chiang Kai-shek for China. The Japanese delegation included Foreign Minister Mamoru Shigemitsu and General Yoshijirō Umezu, who signed under orders from Emperor Shōwa (Hirohito). The assembled naval and air units, including vessels from the Royal Navy and aircraft from the United States Army Air Forces, formed a visible tableau behind dignitaries.

The instrument required cessation of hostilities, disarmament, and the placement of Japanese authority under the control of the Supreme Commander for the Allied Powers (SCAP) led by Douglas MacArthur. It authorized landing of occupation forces from units such as the Eighth United States Army, British Commonwealth Occupation Force, and contingents from Soviet Red Army in specified zones. The document facilitated legal processes including war crimes prosecutions by the International Military Tribunal for the Far East and revocation of treaties like the Tripartite Pact; it set the stage for subsequent treaties including the Treaty of San Francisco (1951) and arrangements affecting territories such as Korea, Taiwan, Ryukyu Islands, and Karafuto. The legal framework touched administrative matters overseen by institutions like the Allied Council for Japan, and guided reforms influenced by advisers linked to United States Department of State and legal scholars associated with the Harvard Law School and Yale Law School.

Major Allied signatories included Douglas MacArthur, Chester W. Nimitz, representatives of United Kingdom such as Arthur Tedder or his delegates, Soviet signatories acting under directives from Joseph Stalin, Chinese representatives reporting to Chiang Kai-shek, and delegates from Australia and New Zealand. Japanese signatories represented the Imperial Japanese Government, the Imperial Japanese Army under leaders like Yoshijirō Umezu, and the Imperial Japanese Navy through officials designated by Prime Minister Kantarō Suzuki and Emperor Shōwa.

Occupation implementation involved demobilization overseen by Supreme Commander for the Allied Powers (SCAP), economic reforms guided by advisers influenced by John R. Barton and economists tied to United States Department of the Treasury, land reform initiatives comparable to measures in Germany and Italy, and social changes with input from scholars connected to University of Tokyo and Kyoto University. The surrender precipitated political transitions including the promulgation of the Constitution of Japan (1947), trials at the International Military Tribunal for the Far East, repatriation of displaced persons under programs like those administered by the International Red Cross, and eventual restoration of sovereignty culminating in the San Francisco Peace Treaty.
