What was the name of the document signed aboard USS Missouri that formally ended Japan’s war?

The Japanese Instrument of Surrender was the document signed aboard USS Missouri that formally ended Japan’s war.

The document was signed in Tokyo Bay on September 2, 1945. Japanese representatives signed first, followed by General Douglas MacArthur for the Allied powers and representatives of the United States, China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand.

The instrument stated that Japan accepted the provisions of the Potsdam Declaration and ordered Japanese forces to cease hostilities and surrender. It was not a peace treaty in the usual sense; it was a capitulation document that established the immediate conditions for ending the conflict and beginning the Allied occupation.

The Japanese and Allied copies differed in a famous clerical detail. Canadian representative Lawrence Moore Cosgrave signed on the wrong line, so later titles were corrected by hand on the Japanese copy. The instrument took effect at 9:25 a.m. Japan Standard Time, completing the formal process that had been publicly announced by Hirohito on August 15.
