Tsutomu Yamaguchi

Tsutomu Yamaguchi (山口 彊, Yamaguchi Tsutomu?) (March 16, 1916 – January 4, 2010) was a Japanese national who survived both the Hiroshima and Nagasaki atomic bombings during World War II. Although at least 160 people are known to have been affected by both bombings, he is the only person to have been officially recognized by the government of Japan as surviving both explosions.

A resident of Nagasaki, Yamaguchi was in Hiroshima on business for his employer Mitsubishi Heavy Industries when the city was bombed at 8:15 am, on August 6, 1945. The following day, he returned to Nagasaki and, despite his wounds, also returned to work on August 9, the day of the second atomic bombing. In 1957, he was recognized as a hibakusha (explosion-affected person) of the Nagasaki bombing, but it was not until March 24, 2009 that the government of Japan officially recognized his presence in Hiroshima three days earlier. He died of stomach cancer on January 4, 2010 at the age of 93.
