Kan-on Bridge
Kengo Nikawa (then, 59) was exposed to the bomb crossing the Kan-on
Bridge by bike going from his home to his assigned building demolition site in
the center of the city. He suffered major burns on his right shoulder, back,
and head and took refuge in Kochi-mura Saiki-gun. He died on August 22.
Kengo was never without this precious watch given him by his son, Kazuo.

Sixty eight years ago today, on August 6, 1945, at 8:15 in the morning, the American B-29 bomber Enola Gay
dropped an atomic bomb over the center of the city of Hiroshima, Japan. Hiroshima was the first target ever attacked with nuclear weapons in the history of the world.
The bomb exploded about 200 yards over the city, creating a 13 kiloton explosion, a fireball, a shock-wave, and a burst of radiation. On the day that the bomb was dropped, there were about 255,000 people living in Hiroshima.
The explosion completely incinerated everything within a one mile radius of the city center. The shock-wave and the fires ignited by the explosion damaged or completely destroyed about nine-tenths of the buildings in the city. Somewhere between 70,000 and 80,000 people–that is, about one third of the entire population of the city–died immediately. The heat of the explosion vaporized or burned alive many of those closest to ground zero. Others were killed by the force of the shock-wave or crushed under collapsing buildings. Many more died from acute radiation poisoning
–that is, from the effects of having their internal organs burned away in the intense radiation from the blast.
By December 1945, thousands more had died from their injuries, from radiation poisoning, or from cancers related to the radioactive burst or the fallout. It is estimated that the atomic bombing killed about 140,000 people, and left thousands more with permanent disabilities.
Almost all of the people maimed and killed were civilians. Although there were some minor military bases near Hiroshima, the bomb was dropped on the city center, several miles away from the military bases on the edge of town. Hiroshima was chosen as a target, even though it had little military importance, because It is a good radar target and it is such a size that a large part of the city could be extensively damaged. There are adjacent hills which are likely to produce a focussing effect which would considerably increase the blast damage.
1. Hiroshima was also one of the largest Japanese cities not yet damaged by the American firebombing campaign. Military planners believed it strategically important to demonstrate as much destruction as possible from the blast.
Thomas Ferebee, a bombadier for the United States Army, was the man who dropped the atomic bomb on Hiroshima. His commanding officer was the pilot of the Enola Gay, Paul Tibbets. Tibbets and Ferebee were part of the XXI Bomber Command, directed by Curtis LeMay. LeMay planned and executed the atomic bombings at the behest of Secretary of War Henry L. Stimson and President Harry Truman.
Kengo Nikawa died on August 22nd, 1945 because of the bombing. This is his pocket watch.
We will never know the names of many of the 140,000 other residents of Hiroshima who were killed by the bombing. We have only estimates because the Japanese government was in a shambles by this point in the war, and countless records, of those that were successfully kept, were consumed by the flames, along with the people whose lives they recorded.
Three days later, on August 9, 1945, CBS broadcast a recorded address by President Harry S. Truman about the atomic bombing. It was broadcast on the same day that the U.S. government sent bombers to incinerate a second city, Nagasaki, with atomic weapons. Here is what Truman said:
In his radio address on August 9, Truman described Hiroshima, a port city of some 255,000 people, as a military base,
and then said, That was because we wished in this first attack to avoid, insofar as possible, the killing of civilians.
The bomb was dropped on the city center, far away from military installations.
On that bright morning in August, with a sudden flash, brighter than the sun, the downtown of an industrial city was converted into a scene of hell. The sky went dark, buildings were thrown into the ground, and everything began to burn. People staggered through the ruins, with their eyes blinded, with their clothing burned off their bodies, with their own skin and faces burned off in the heat. Everyone was desperate for water, because they were burning, because everything was unbearably hot. They begged soldiers for water from their canteens; they drowned themselves in cisterns. Later, black rain began to fall from the darkened sky. The people thought it was a deliverance. They tried to catch the black rain on their tongues, or they caught it and drank it out of cups. But they didn’t know that the rain was fallout. They didn’t know that it was full of radiation and as they drank it it was burning them away from the inside. There was no refuge, no sanctuary; there was nobody to help. The city was burning, medical workers were almost all downtown, and so over 90% of the doctors, and over 90% of the nurses, were killed or injured in the bombing. Because of the targeting of the city center, about 85% of the people killed in Hiroshima were civilians — about 120,000 of the 140,000 men, women and children killed — vaporized or carbonized by the heat, crushed to death in the shockwave, burned to death, killed quickly or slowly by radiation poisoning and infections and cancers eating their bodies alive.
It is worth remembering that the atomic bombing of the Hiroshima city center — the first ever use of atomic weapons against human targets — a bombing in which the United States government’s forces deliberately targeted a civilian center — a bombing that the United States government carried out with the explicit intention of obliterating an entire city in seconds, in order to break enemy morale
— an attack in which that government’s forces turned weapons on civilians that destroyed 90% of an industrial metropolis, and killed over half of all the people living in it — remains the deadliest act of terrorism in the history of the world.
