How Many People Died in Hiroshima and Nagasaki?
A total of about 185,000 people died in the Hiroshima and Nagasaki bombings and their immediate aftermath. Of these, around 110,000 died instantly, and the rest died within days of trauma and radiation sustained in the bombing.
On Aug. 6, 1945, days after the Japanese leadership refused to discuss terms of surrender, the American bomber plane Enola Gay dropped a uranium-based atomic bomb nicknamed “Little Boy” on Hiroshima, an important military base. About 6 square miles of the city were destroyed in the blast, and an intense fire lasted for three days. Three days later, a larger plutonium-based bomb, “Fat Man,” was dropped on Nagasaki, a port city. A third of the city was destroyed. On Aug. 14, Emperor Hirohito agreed to the Allies’ terms for surrender.
