He survived Hiroshima, returned home to Nagasaki and was hit by a second atomic bomb three days later: The story of Tsutomu Yamaguchi

On August 6, 1945, Tsutomu Yamaguchi was preparing to leave Hiroshima and return to his family in Nagasaki when a blinding flash lit up the sky. The 29-year-old engineer was on a business assignment for Mitsubishi Heavy Industries, working on the design of oil tankers. Within seconds, the city was devastated by the world's first atomic bomb used in warfare.

Yamaguchi was thrown into the air, temporarily lost his sight and hearing, and suffered severe burns across his upper body.He managed to reach a railway station and spent the night in Hiroshima before making the journey back to Nagasaki. He had survived an atomic bombing and was finally home with his wife, Hisako, and their infant son. But the ordeal was far from over.

Three days later, on August 9, as he reported for work and attempted to explain to his colleagues what he had witnessed, a second atomic bomb exploded over his hometown.Yamaguchi was among the people caught in both attacks.
