A newly unearthed memoir by Kiyoshi Tanimoto offers a detailed first-person account of the immediate aftermath of the atomic bombing of Hiroshima. The document, titled "Hiroshima, 8:15," describes the Methodist minister's harrowing journey through the devastated city on Aug. 6, 1945.
Tanimoto, 36, had risen early that day after overnight air-raid warnings disrupted sleep across the city. He had traveled across Hiroshima to a house and arrived at precisely 8:15 a.m.—the exact moment the "Little Boy" atomic bomb detonated. The explosion instantly killed more than 60,000 people, according to historical estimates of immediate fatalities.
Immediately after the blast, Tanimoto ran out of the Matsui estate where he had been seeking shelter. He observed "bloody soldiers" at the mouth of a dugout they had been digging. The landscape around him had been transformed into a scene of widespread destruction and human suffering.
His memoir recounts devastation across the entire city center of Hiroshima. Structures were leveled for miles in every direction, reduced to splintered wood, twisted metal and pulverized concrete. Fires erupted from the intense heat of the blast and spread rapidly, consuming what little remained standing.
Tanimoto encountered countless injured people during his desperate journey, many disoriented, severely burned and suffering from grievous wounds. He described scenes of "pitifully injured people" struggling to move or find help during the ruins. The air filled with the cries of the wounded and the acrid smell of burning flesh.
His urgent priority was to locate his wife and infant daughter, whose safety was unknown during the chaos. He also sought out members of his church community, driven by his pastoral duties and deep personal concern for his congregation.
During his search, Tanimoto witnessed suffering caused by radiation exposure, a then-unfamiliar consequence of the atomic weapon. He described people exhibiting severe burns, rapid hair loss and other ailments that defied immediate medical understanding.
He recounted attaching himself to an old woman who walked along in a daze, clutching her head with her left hand. She supported a small boy, aged three or four, on her back with her right hand, struggling through the debris-strewn streets. The woman cried, "I'm hurt!"
This interaction is one of several personal encounters Tanimoto documented in his account. His memoir illustrates the immediate impact of the bombing, capturing the struggle for survival, the search for loved ones and the psychological shock experienced by survivors.
The rediscovery of Tanimoto's memoir adds a direct testimony to the historical record of the Hiroshima bombing, nearly eight decades after the event. His perspective as a survivor searching for loved ones provides insight into the human cost beyond casualty figures and strategic considerations.
The memoir will be published as a book under the title "Hiroshima, 8:15." Plans are also underway for its adaptation into a film.
