Final answer:
Admiral Chester Nimitz accepted the Japanese surrender aboard the battleship USS Missouri on September 2, 1945, marking the end of World War II.
Step-by-step explanation:
Fleet Admiral Chester Nimitz, the commander of the US Pacific fleet during World War II, was promoted to the highest-ranking officer in the navy and went on to accept the surrender of Japanese forces aboard a historic US Navy ship. On September 2, 1945, following the Japanese acceptance of the Potsdam Declaration after the atomic bombings and Soviet invasion of Manchukuo, a formal ceremony took place on the battleship USS Missouri.
This event, held in Tokyo Bay, marked the end of World War II with General Yoshijirō Umezu, the army's chief of staff, signing the surrender documents while representatives of the Allied Powers stood behind General Douglas MacArthur.
