The Japanese Instrument of Surrender was the written agreement that formalized the surrender of the Empire of Japan, marking the end of World War II. It was signed by representatives from the Empire of Japan, the United States of America, the Republic of China, the United Kingdom of Great Britain and Northern Ireland, the Union of Soviet Socialist Republics, the Commonwealth of Australia, the Dominion of Canada, the Provisional Government of the French Republic, the Kingdom of the Netherlands, and the Dominion of New Zealand. The signing took place on the deck of USS Missouri in Tokyo Bay on September 2, 1945.

The date is sometimes known as Victory over Japan Day, although that designation more frequently refers to the date of Emperor Hirohito's Gyokuon-hōsō (Imperial Rescript of Surrender), the radio broadcast announcement of the acceptance of the terms of the Potsdam Declaration at noon Japan Standard Time on August 15.

We, acting by command of and in behalf of the Emperor of Japan, the Japanese Government and the Japanese Imperial General Headquarters, hereby accept the provisions set forth in the declaration issued by the heads of the Governments of the United States, China, and Great Britain on 26 July 1945 at Potsdam, and subsequently adhered to by the Union of Soviet Socialist Republics, which four powers are hereafter referred to as the Allied Powers.

We hereby proclaim the unconditional surrender to the Allied Powers of the Japanese Imperial General Headquarters and of all Japanese Armed Forces and all Armed Forces under Japanese control wherever situated.

We hereby command all Japanese forces wherever situated and the Japanese people to cease hostilities forthwith, to preserve and save from damage all ships, aircraft, and military and civil property, and to comply with all requirements which may be imposed by the Supreme Commander for the Allied Powers or by agencies of the Japanese Government at his direction.

We hereby command the Japanese Imperial General Headquarters to issue at once orders to the commanders of all Japanese forces and all forces under Japanese control wherever situated to surrender unconditionally themselves and all forces under their control.

We hereby command all civil, military, and naval officials to obey and enforce all proclamations, orders, and directives deemed by the Supreme Commander for the Allied Powers to be proper to effectuate this surrender and issued by him or under his authority; and we direct all such officials to remain at their posts and to continue to perform their non-combatant duties unless specifically relieved by him or under his authority.

We hereby undertake for the Emperor, the Japanese Government, and their successors to carry out the provisions of the Potsdam Declaration in good faith, and to issue whatever orders and take whatever action may be required by the Supreme Commander for the Allied Powers or by any other designated representative of the Allied Powers for the purpose of giving effect to that declaration.

We hereby command the Japanese Imperial Government and the Japanese Imperial General Headquarters at once to liberate all Allied Prisoners of War and civilian internees now under Japanese control and to provide for their protection, care, maintenance, and immediate transportation to places as directed.

The authority of the Emperor and the Japanese Government to rule the State shall be subject to the Supreme Commander for the Allied Powers, who will take such steps as he deems proper to effectuate these terms of surrender.
