In a world where tales of resilience and survival often defy belief, the story of Tsutomu Yamaguchi stands as one of the most extraordinary. This Japanese man not only survived the catastrophic atomic bombing of Hiroshima but also endured the second bombing in Nagasaki just three days later. His life, marked by tragedy and unimaginable perseverance, is a testament to the strength of the human spirit.

A Business Trip That Changed Everything

On the morning of August 6, 1945, Tsutomu Yamaguchi, a 29-year-old naval engineer, was preparing to leave Hiroshima after a three-month business trip. As he made his way to the docks to catch a ferry home, the world changed forever. At 8:15 a.m., the American B-29 bomber Enola Gay dropped “Little Boy,” the first atomic bomb ever used in warfare.

The explosion levelled the city, killing tens of thousands instantly. Yamaguchi, who was approximately three kilometres from the epicentre, was thrown into the air by the blast. He suffered severe burns on the left side of his body, burst eardrums, and temporary blindness. Disoriented and in immense pain, he managed to find shelter and survive the night in a city turned to ash.

Returning to Nagasaki

Despite his injuries, Yamaguchi was determined to return to his family in Nagasaki. On August 8, he boarded a train back to his hometown, where he reunited with his wife and infant son. The next day, despite his trauma, Yamaguchi reported to work at the Mitsubishi shipyard. He was describing the horrors he had witnessed in Hiroshima to his supervisor when, at 11:02 a.m., the second atomic bomb, “Fat Man,” detonated over Nagasaki.

Once again, Yamaguchi was about three kilometres from ground zero. This time, he was shielded by the office building, which absorbed much of the blast. However, the force of the explosion destroyed the structure, and Yamaguchi sustained further injuries. Miraculously, he survived.

A Life Marked by Resilience

In the days following the Nagasaki bombing, Yamaguchi and his family were exposed to dangerous levels of radiation. Despite the long-term health risks, including radiation sickness, he lived a relatively normal life. Yamaguchi went on to have two more children, both of whom were born healthy.

For decades, Yamaguchi rarely spoke of his experiences. However, as he grew older, he began sharing his story, driven by a desire to promote peace and disarmament. In 2009, he was officially recognised by the Japanese government as a nijū hibakusha—a double atomic bomb survivor.

A Legacy of Peace

Yamaguchi spent his later years advocating for the abolition of nuclear weapons, using his story as a powerful reminder of their devastating consequences. “The reason that I hate the atomic bomb is because of what it does to the dignity of human beings,” he once said.

Yamaguchi lived to the age of 93, passing away in 2010 from stomach cancer. His remarkable life is a testament to human endurance and a reminder of the need for peace in a world that still grapples with the legacy of nuclear weapons.

Why Yamaguchi’s Story Matters

Tsutomu Yamaguchi’s story is not just about survival—it is about resilience, hope, and the importance of remembering history to prevent its darkest chapters from repeating. As one of the few individuals to have experienced the horror of both atomic bombings, Yamaguchi’s life serves as a profound lesson on the fragility and strength of humanity.

His legacy endures, not just in Japan but around the world, as a symbol of peace and the enduring will to live—even in the face of unimaginable destruction.
