There were 2, 'Little Boy', dropped on Hiroshima on August 6, 1945 and 'Fat Man' dropped on Nagasaki on August 9, 1945. Six days later, on August 16, Japan announced surrender and on September 2, 1956 Japan signed an Instrument of Surrender.

In the six months preceding dropping the atomic bombs, the US fire bombed 67 Japanese cities, followed by issuing the Potsdam Declaration on July 26, 1945 calling for Japan to surrender. Japan ignored the request.
