The Nagasaki Atomic Bomb Museum is exhibiting 26 recently discovered photographs taken a year and four months after the bomb was dropped on Aug. 9, 1945.
Nagasaki Municipal Government officials found the pictures, including one showing ground zero, at the U.S. National Archives.
Notes written on the back of the pictures indicate they were taken on Dec. 6, 1946, by one of the American researchers who visited Nagasaki to investigate the damage caused by the bomb.
