Hiroshima Day 2022: History, importance and significance of the day

Hiroshima Day is observed on August 6 to commemorate the atomic bombing of Hiroshima, Japan, in 1945, at the end of World War II. The bombings killed over 200,000 people in just seconds and injured thousands more.

It was 70 years ago this week that the United States dropped an atomic bomb on the city of Hiroshima, Japan, killing more than 140,000 people—more than anyone else during World War II. The bombing annihilated a large swath of the city, including a school where more than 80% of the children who died were between 6 and 11 years old.

One year after the bombing, on Aug. 6, 1945, Japanese executive Nagasaki was also hit with an atomic bomb. That day killed about 35,000 people, making it the second deadliest attack in history after Hiroshima.


On Aug. 6, 1945, during World War II, the U.S. B-29 Superfortress Enola Gay dropped an atomic bomb code-named "Little Boy" on Hiroshima, Japan, resulting in an estimated 140,000 deaths. (Three days later, the United States exploded a nuclear device over Nagasaki; five days after that, Imperial Japan surrendered.)

On August 6th, the Hiroshima Day Memorial Service is held to commemorate the victims of the atomic bombing of Hiroshima. The service is celebrated in many countries around the world, and it is an important event in the history of Hiroshima.

Hiroshima city was a major hub of industrial and military activities in Japan, a part of the Axis coalition, including Nazi Germany and the Kingdom of Italy. The Axis stood against the Allies, which included Britain, the United States, the Soviet Union and China.
