📅 What Is Hiroshima Day?
Hiroshima Day, observed annually on August 6, marks the anniversary of the atomic bombing of Hiroshima, Japan, in 1945—the first-ever use of a nuclear weapon in warfare.
In 2025, August 6 falls on a Wednesday, a day to pause and reflect.
💥 The Tragedy of August 6, 1945
At 8:15 AM JST on August 6, 1945, the U.S. B‑29 bomber Enola Gay dropped the atomic bomb Little Boy over Hiroshima. The city suffered immediate devastation—an estimated 70,000 people died instantly, and by the end of the year around 140,000 had perished from injuries and radiation illness. Around two-thirds of the city was destroyed.
Hiroshima was a major military and logistics hub with a population of about 340,000 to 350,000 at the time. The blast left lasting scars: “nuclear shadows” on structures, massive radiation effects, and long-term health crises.

- Emergence of Hibakusha: Survivors of the bombing faced lifelong illness and stigma—many now elderly are designated as memory keepers, preserving oral testimonies.
- Global Call for Peace & Disarmament: A solemn reminder of nuclear dangers and the moral imperative to pursue disarmament and diplomacy.
