When photographer hibakusha—the Japanese word for those affected by the August 1945 attacks. “I sat at the Nagasaki Peace Park for hours trying to differentiate between tourists and locals who were visiting to pray for a loved one—they often wore juzu, or prayer beads,” says Sakaguchi, who immigrated to the U.S. from Japan as an infant in the 1990s. After five hours of people watching, she struck up a conversation with the daughter of a survivor, who agreed to introduce her to eight hibakusha. Survivors’ reluctance to discuss their experiences stems in large part from the The Last Survivors of Hiroshima have become increasingly common—a testament to both survivors’ willingness to defy the long-standing culture of silence and the pressing need to preserve these stories as hibakusha’s numbers dwindle. Aerial views of Hiroshima before (left) and after (right) the bombing When planning for the war in the Pacific's next phase, the U.S. invasion of mainland Japan, the Truman administration Throughout World War II, the Japanese code of bushido, or “way of the warrior,” guided much of Emperor Hirohito’s strategy. With its actions in bushido mindset led Japanese soldiers to view their lives as expendable in service of the emperor and consider suicide more honorable than yielding to the enemy. Later in the war, as American troops advanced on the Japanese mainland, civilians indoctrinated to believe that U.S. soldiers would torture and kill those who surrendered also started engaging...

Hiroshima: Before and After Aerial view of Hiroshima, Japan On August 6, 1945,at 8:15 a.m., the crew of the B-29 bomber Enola Gay dropped the first wartime atomic bomb over Hiroshima, Japan, a bustling regional hub that served as an important militarycommunications center, storage depot and troop gathering area. The bomb, code-named "Little Boy," detonated withan estimated 15,000 tonsof TNT, destroying five square miles of the city and directly killing some 70,000 people. Final casualty numbers remain unknown; by the end of 1945, injuries and radiation sickness had raised the death toll to more than 100,000. In subsequent years, cancer and other long-term radiation effects steadily drove the number higher. Aerial view of Nagasaki, Japan Three days after the destruction of Hiroshima, another American bomber dropped its payload over Nagasaki, some 185 miles southwest of Hiroshima, at 11:02 a.m. Not the original intended blast site, Nagasaki only became the target after the crew found that city, Kokura, obscured by clouds. The Nagasakiexplosive, a plutonium bombcode-named “Fat Man,”weighed nearly 10,000 pounds and was built to produce a 22-kiloton blast. Its destructive force wiped out about 30 percent of the city. Some 60,000 to 80,000 people died in Nagasaki, both from direct exposure and long-term side effects of radiation. The crew of the Enola Gay. Left to right kneeling; Staff Sergeant George R.

When word of the attack on Hiroshima, Japan, reached the scientists at Los Alamos National Laboratory in the United States on Aug. 6, 1945, physicist J. Robert Oppenheimer was greeted at the base theater by a roaring, foot-stomping crowd. The man who had done more than any other to create the atom bomb responded by clasping his hands over his head, like a boxing champion. Yet at a celebration party later that evening, a few couples danced, but others just quietly talked and drank, unsure what to feel. Off in one corner, Oppenheimer discussed a telex that had just arrived from Washington with the first damage report. The chief scientist grew depressed. As he left the party, he saw a young scientist throwing up in the bushes. He said to himself: “The reaction has begun.” This article is adapted from Road to Surrender by Evan Thomas (Random House, 336 pp., , May 2023) This article is adapted from Road to Surrender by Evan Thomas (Random House, 336 pp., $28, May 2023) But it had not—not yet. Most Americans approved of dropping two atomic bombs on Japan; some wished their countrymen had dropped more. Many people—millions of veterans returning home, their long-awaiting families—were grateful to have avoided an invasion. Their worries focused more on whether Russia would get the bomb, or about whether they could find a new car or a house, a job, or a spouse.

Source: In essence, a hydrogen bomb employs fission to fuel a fusion process, whereas an atomic bomb is solely a fission-based weapon. In other words, a hydrogen bomb is set off by an atomic bomb. To better understand this, it is probably worth giving a quick overview of each. An atomic bomb, or A-bomb for short, is a form of nuclear weapon that detonates as a result of the tremendous energy unleashed by nuclear fission. Because of this, this kind of bomb is also often referred to as a fission bomb. A material capable of fission (fissile material) is given supercritical mass, which is the point at which fission occurs — the nuclear breaks apart. This can be done by either firing one portion of a sub-critical mass into another or by compressing the sub-critical material with conventional explosives. This material usually consists of either enriched plutonium or enriched uranium. The fission reaction is incredibly powerful. Atomic bombs are measured in kilotons, with each unit equal to the explosive force of 1,000 tons of TNT. The atomic weapon which leveled Hiroshima in 1945 had a yield of around 15 kilotons; or the explosive power of 15,000 tons of TNT. A single atomic bomb can produce between around a ton and 500 kilotons of the explosive TNT. Additionally, radioactive fission fragments are released by the bomb as a result of the heavier nuclei splitting into smaller ones. When detonated, fission fragments make up the majority of nuclear fallout. Hydrogen bombs, or H-bomb...

“I'm mentally trying hard to pretend I’m OK,” Takano, 82, told NBC News by telephone from Japan in Japanese. For decades Takano quietly lived with his ailments. He was not recognized as a “hibakusha” — a survivor of the bombing — because he was not within the immediate radius of the blast that killed an estimated 140,000 people, vaporizing them instantly or poisoning them slowly. A correspondent stands in the rubble in Hiroshima on Sept. 8, 1945, a month after the first atomic bomb ever used in warfare was dropped by the U.S. Stanley Troutman / AP But last week, a Japanese court finally acknowledged that he and 83 other plaintiffs had been exposed to dangerous radiation from “black rain” — the nuclear fallout that poured from the skies in the aftermath of the explosion. “We are doing this because we want to deliver the truth,” Takano said of the suit filed in 2015. “It’s too late to stand up after everyone dies.” Although the case has renewed public consciousness of the bombing, and the technology that made it, some worry that the world hasn’t heeded the dangers of nuclear weapons. And today, the awesome and terrifying destructive power unleashed by “Little Boy,” as the Hiroshima bomb was known, still haunts the world in the form of vast stockpiles of nuclear weapons. And as the aging Hibakusha die, many fear ‘Bigger than lightning’ Takano was at school about 12 miles from the bomb's hypocenter, or detonation point, on Aug 6, 1945. He still recalls seeing a flash “bigger t...
