JAPAN - Hiroshima

Hiroshima was the first city targeted by a nuclear weapon, when the United States Army Air Forces dropped an atomic bomb on the city.
On Monday, August 6, 1945, at 8:15 a.m., the nuclear weapon "Little Boy" was dropped on Hiroshima from an American Boeing B-29 Superfortress, directly killing an estimated 70,000 people, including 20,000 Japanese combatants and 2,000 Korean slave laborers. By the end of the year, injury and radiation brought the total number of deaths to 90,000–166,000. The population before the bombing was around 340,000 to 350,000. About 70% of the city's buildings were destroyed, and another 7% severely damaged.
Hiroshima Peace Memorial Park is located in the center of the city. It is dedicated to the legacy of Hiroshima as the first city in the world to suffer a nuclear attack, and to the memories of the bomb's direct and indirect victims (of whom there may have been as many as 140,000). The Hiroshima Peace Memorial Park is visited by more than one million people each year.
