What are the odds of surviving an atomic bomb? Infinitesimal. What about surviving two? Meet Tsutomu Yamaguchi, the incredible man who defied those odds, becoming the only officially recognized survivor of both the Hiroshima and Nagasaki atomic bombings.

On August 6, 1945, Yamaguchi, a shipbuilding engineer, was in Hiroshima for a business trip. Just 3 kilometers from ground zero, the “Little Boy” bomb detonated, throwing him to the ground, severely burning him, and rupturing his eardrums. He spent a night in an air-raid shelter amidst the devastation.

Despite his injuries, he was determined to get home to Nagasaki. He arrived on August 8th and, the very next morning, was at work recounting the horrific events in Hiroshima to his supervisor. Suddenly, a blinding flash filled the room – the “Fat Man” had just exploded over Nagasaki, his hometown.

Miraculously, Yamaguchi was relatively unharmed this second time, shielded by a sturdy building. He lived to be 93, eventually campaigning for nuclear disarmament. His story isn’t just one of incredible luck, but a powerful, living testament to the sheer will to survive against the unthinkable.
