Hiroshima Day 2025: What’s the history and significance of the ‘catastrophic moment’ in World War II
Hiroshima Day is observed every year on August 6 to remember the atomic bombing of Hiroshima in Japan, 1945. The attack led to many deaths and left many survivors (Hibakusha) suffering from the lasting effects of radiation.
Date and Importance
Hiroshima Day is observed every year on August 6. In 2025, the day will mark 80 years since the atomic bombing of Hiroshima, Japan, in 1945. It is a time to remember the tragedy, its impact and renew the call for peace.
History
According to the National Museum of Nuclear Science & History, the United States dropped the first atomic bomb on Hiroshima in Japan on 6 August, 1945, during World War II. The atomic bomb, called "Little Boy", used uranium and exploded with the full power of about 13,000 tonnes of TNT.
At that time, Hiroshima had a population of about 280,000 to 290,000 civilians and 43,000 soldiers. It is estimated that 90,000 to 166,000 people died within four months after the bombing.
Significance
This year marks the 80th anniversary of the Hiroshima bombing. Many hibakusha (atomic bomb survivors) are now in their late 80s or older, and their numbers are rapidly decreasing. Sharing their stories is important so that future generations understand what happened.
Why this day still matters
Hiroshima Day sends a strong message about the dangers of nuclear weapons. Even today, there are more than 12,000 nuclear weapons in the world, and the rising global tensions show that the message of peace is still important.
