Summary
Today marks the detonation of the atomic bomb over the Japanese city of Hiroshima in 1945.

Also known as World Day for the Prohibition of Nuclear Weapons, Hiroshima Day is observed on August 6th every year.

The day is a solemn commemoration of the atomic bombing of the Japanese city of Hiroshima during World War ll. It serves as a reminder of the devastating impact of nuclear weapons and advocates for peace and the abolition of nuclear armaments. 

On August 6th 1945, during World War II, the United States dropped an atomic bomb on the Japanese city of Hiroshima. The bomb, codenamed "Little Boy," was the first ever used in warfare and was dropped by a U.S. B-29 bomber named Enola Gay. The devastating attack had a profound impact on the course of history and the use of nuclear weapons.

The bombing of Hiroshima resulted in immense destruction and loss of life. The immediate aftermath saw the city engulfed in a massive firestorm, with a large area reduced to ruins. The estimated death toll from the initial blast, fires, and radiation exposure in the months and years that followed was approximately 140,000 people by the end of 1945.
