The story of Tsutomu Yamaguchi, the only survivor of both Hiroshima and Nagasaki atomic bombings

Tsutomu Yamaguchi endured both atomic bombings in August 1945, surviving Hiroshima on Aug. 6 before finding himself in Nagasaki three days later, on Aug. 9.

His experience became a story of survival against unimaginable odds. After the war, Yamaguchi turned what he had lived through into activism, campaigning for nuclear disarmament at the United Nations.

Through that work, he sought to show the catastrophic effects of nuclear armament.
