Hiroshima after the atomic bombing in 1945

During World War II, Hiroshima was a center for both industrial and military activities. It was the headquarters of Field Marshal Shunroku Hata’s Second General Army, commanding the defense of southern Japan, and was located in Hiroshima Castle. Hata’s army consisted of about 400,000 men, most of whom were on Kyushu where an Allied invasion was correctly anticipated.

Hiroshima was a beehive of war industry, manufacturing planes, boats, bombs, rifles, and handguns, and large stockpiles of military supplies. The city was also a communications center, a key port for shipping and an assembly area for troops. At the time of the atomic bombing, the population of Hiroshima was approximately 340,000–350,000.

Looking upstream on the Motoyasugawa, toward the Product Exhibition Hall building (dome) in Hiroshima, before the bombing. The domed building was almost directly below the detonation, which occurred in mid-air, about 2,000 feet (600 meters) above this spot. Today, much of the building remains standing, and is known as the Atomic Bomb Dome, or the Hiroshima Peace Memorial.

Looking north from the vicinity of the Aioi Bridge (the central T-shaped bridge targeted by the bomb). Wooden houses line the bank of the Otagawa, with traditional Japanese river boats in the foreground.

On August 6, 1945, a mushroom cloud billows into the sky about one hour after an atomic bomb was dropped by American B-29 bomber, the Enola Gay, detonating above Hiroshima, Japan. Nearly 80,000 people are believed to have been killed immediately, with possibly another 60,000 survivors dying of injuries and radiation exposure by 1950.

“Direction of blast” chalk marks and outlines of the feet of a victim caught in the explosion. The intense heat of the initial flash of the detonation seared every nearby surface, leaving inverted “shadows,” like those seen on this bridge left by the railings and by a person who had been standing in this place.
