Tokyo , Japan ( CNN ) -- The only man recognized as a survivor of both atom bombs dropped in Japan at the end of World War II has died . Tsutomu Yamaguchi died Monday after a battle with stomach cancer . He was 93 . He had long been a certified `` hibakusha , '' or radiation survivor , of the August 9 , 1945 , atomic bombing in Nagasaki . In March 2009 , the Japanese government confirmed that he had also survived Hiroshima three days earlier . On that day , the U.S. B-29 bomber Enola Gay dropped an atomic bomb nicknamed `` Little Boy , '' which exploded over Hiroshima at 8:15 in the morning . Yamaguchi happened to be in the city on a business trip for his employer , Mitsubishi Shipyard . Many years later , he recalled the bombing in a story that appeared in the British newspaper The Times . `` It was very clear , a really fine day , nothing unusual about it at all . I was in good spirits , '' he said . `` As I was walking along , I heard the sound of a plane , just one . I looked up into they sky and saw the B-29 , and it dropped two parachutes . I was looking up into the sky at them , and suddenly ... it was like a flash of magnesium , a great flash in the sky , and I was blown over . '' Badly burned , Yamaguchi returned home to Nagasaki only to experience horror again . `` My double radiation exposure is now an official government record , '' Yamaguchi told reporters last year after his official recognition . `` It can tell the younger generation the horrifying history of the atomic bombings even after I die . '' About 140,000 people perished in Hiroshima and an additional 70,000 in Nagasaki . Many of those who survived suffered a lifetime of radiation-related health problems , including cancers . Yamaguchi lost his hearing in his left ear in the blasts , and suffered from acute leukemia , cataracts and other bomb-related illnesses in subsequent years . Yamaguchi spoke publicly about his experiences and appealed for the abolition of nuclear weapons at venues such as the United Nations . He was visited in his hospital room in Nagasaki last month by filmmaker James Cameron , who wanted to discuss ideas for a film about nuclear weapons , the Japanese newspaper Mainichi reported .
