'Hibakusha' is the word used by the Japanese to mean anyone who was effected by either of the atomic bombing of Hiroshima or Nagasaki. However, one unfortunate man (or incredibly lucky, depending on how you look at it), survived BOTH attacks. Tsutomu Yamaguchi worked in Hiroshima, where he was when the bomb was dropped. He survived it, then returned to his home city: Nagasaki, which was then bombed. He survived that bomb too, although he died in 2010 of cancer, undoubtedly caused by the nuclear fallout.
