Japan #5 – Hiroshima – December 2014
At 8:15 AM, August 6, 1945, an American B-29 bomber carried out the World’s first atomic bombing. The bomb was about 3 m, (9.8 ft.), long and weighed about 4 tons. It was called “Thin Man” at first because of its long thin design. When the actual bomb turned out to be shorter than expected, the name was changed to “Little Boy”.
“Little Boy” that changed the World
The bomb exploded approximately 600 m, (2,000 ft), above and 160 m, (525 ft), southeast of the Hiroshima Prefectural Industrial Promotion Hall, ripping through and igniting the building, instantly killing everyone in it.
Because the blast struck from almost directly above, some of the center walls remained standing. Even the building’s iron frame could be recognized as a dome. After the war these dramatic remains came to be known as the A-Bomb Dome.
The bomb was delivered by a total of three B-29 bombers. One carried devices for scientific observation, another carried photographic equipment, and the third called Enola Gay, named after Col. Paul Tibbits’ (the pilot) mother, actually carried the bomb.
On the streets of Hiroshima it was just another Monday. It dawned clear and sunny. The yellow air raid alarm was cleared and the hot summer’s day began as usual.
A Fireball blazed like a small Sun
The detonation of the “Little Boy” created a fireball that blazed like a small sun. More than 1,000,000°C, (1,800,032 F°), at its center, the fireball reached a maximum diameter of 280 m, (918 ft.), in two seconds. Surface temperatures near the hypocenter rose up to 4,000°C, (7,232F°). Fierce heat rays and radiation burst out in every direction, expanding the air around the fireball and creating a super high-pressure blast. These factors interacted in complex ways to inflict tremendous damage.
Although the casualties are not precisely known, approximately 140,000 people are believed to have died by the end of 1945. Among them were many school children and South Korean prisoners of war, mobilized to demolish buildings near the city center for fire lanes. Buildings within a 2 km, (1.5 mi), radius of the hypocenter crumbled and burnt to the ground. Death was often presumed from personal effects left behind. Many bodies were never found or identified.
People close to the hypocenter said the atomic explosion looked yellowish red. Those further away reported a bright bluish white light resembling burning magnesium. The intense thermal rays from the fireball caused burns within a radius of up to 3.5 km, (2mi). Those within 1.2 km, (1,312 yd.), of the hypocenter sustained severe injuries to their internal organs and most died within a few days.
As we walked past the shocking photos of the results of this horrific act of war, as an American, I could not help but feel sad, and I could only wonder how many American lives had been saved and the thousands of other soldiers and civilians who would have perished had the war not been stopped in its tracks. And then again, remembering what the Japanese did at Pearl Harbor, I could not repress the smugness of thinking, “Well, did we get your attention?”
“Fat Man” drops on Nagasaki
In fact, the devastation brought to Hiroshima had not been sufficient to convince the Japanese War Council to accept the Potsdam Conference’s demand for unconditional surrender. On August 9 at 1:56 a.m., a specially adapted B-29 bomber, called “Bock’s Car,” after its commander, Frederick Bock, took off from Tinian Island under the command of Major Charles W. Sweeney. Nagasaki was a shipbuilding center, the very industry intended for destruction. The bomb was dropped at 11:02 a.m., 503 m, (1,650 ft.), above the city. The explosion unleashed the equivalent force of 22,000 tons of TNT. The hills that surrounded the city did a better job of containing the destructive force, but the number killed is estimated at anywhere between 60,000 and 80,000 (exact figures are impossible, the blast having obliterated bodies and disintegrated records).
The Emperor of Japan gave his permission for unconditional surrender.
Even though the Japanese War Council still remained divided, Emperor Hirohito, by request of two War Council members eager to end the war, met with the Council and declared, “continuing the war can only result in the annihilation of the Japanese people…” The Emperor of Japan gave his permission for unconditional surrender.
Hiroshima, the City of Peace
The beautiful Memorial Monument for Hiroshima, City of Peace, erected on August 6, 1952, embodies the hope that Hiroshima, will stand forever as a City of Peace. The stone chamber in the center contains the register of Deceased A-bomb Victims. The inscription on the front panel offers a prayer for the peaceful repose of the victims and a pledge on behalf of all humanity never to repeat the evil of war. It expresses the spirit of Hiroshima – enduring grief, transcending hatred, pursuing harmony and prosperity for all, and yearning to genuine, lasting world peace.
