A review of Hiroshima, 8:15: The Lost Memoir by Kiyoshi Tanimoto, 224 Pages, Penguin Random House (August 2026)
The overwhelming sensation in Hiroshima’s Peace Memorial Park—the hypocentre of the atomic bomb’s detonation—is silence. In general, Japan is a quiet place. With the exceptions of karaoke bars, electronic jingles in subway cars, busy crosswalks, and Tokyo’s famous “Shibuya Scramble,” the country is remarkably decorous. But the silence in Hiroshima feels different—more profound and reverent than serene. The peace park spans thirty acres, in which visitors can find a symbolic arch memorialising the children who perished, an “A-bomb dome” that survived the blast and has been preserved in its ruined state, and an understated but deeply moving museum documenting the carnage that unfolded on 6 August 1945. We moved noiselessly from site to site as we paid our respects to the departed.
On that fateful day, however, this port city experienced an even eerier silence after the attack that claimed the lives of an estimated 140,000 residents (out of a total population of slightly more than 350,000). Evidence of the devastation can be found in the exhibits lining the park, and in Hiroshima, 8:15: The Lost Memoir, Kiyoshi Tanimoto’s extraordinary testimony of the bombing and its aftermath, published in August some forty years after his death after it was discovered in a Yale library among the papers of the New Yorker writer John Hersey. A Methodist minister who had studied theology in the US, Tanimoto documents the unimaginable horrors his countrymen suffered, but he still manages to present a surprisingly hopeful view of humanity’s future.
