Tsutomu Yamaguchi radiation ground zero Nagasaki Yamaguchi Hiroshima hibakusha
Perhaps as many as 200 people from Hiroshima sought refuge in Nagasaki. The 2006 documentary Twice Survived: The Doubly Atomic Bombed of Hiroshima and Nagasaki documented 165 nijū hibakusha (lit. double explosion-affected people), nine of whom claimed to be in the blast zone in both cities. On 24 March 2009, the Japanese government officially recognized Tsutomu Yamaguchi as a double hibakusha. He was confirmed to be 3 km (1.9 mi) from ground zero in Hiroshima on a business trip when the bomb was detonated. He was seriously burnt on his left side and spent the night in Hiroshima. He arrived at his home city of Nagasaki on 8 August, the day before the bombing, and he was exposed to residual radiation while searching for his relatives. He was the first officially recognized survivor of both bombings. He died in 2010 of stomach cancer.
