Hiroshima Day History

On August 9, 1945, the United States detonated atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively, during World War II. The aerial bombings killed over 2 lakh people, most of whom were civilians, and remain the only uses of nuclear weapons in an armed conflict. Japan announced its surrender to the Allies on August 15, six days after the bombing of Nagasaki and the Soviet Union's declaration of war against Japan and invasion of Manchuria. The Japanese government signed an instrument of surrender on September 2, ending the war.

Hiroshima Day urges the world to reflect on the devastating impact of nuclear weapons and the urgent need to prevent such horrors from repeating.
