In the year 1945, my great-great grandfather, serving in the army, wondered when he'd get to go home to his wife and the son he'd never seen. He got his wish when the US ended World War II by dropping atomic bombs on Hiroshima and Nagasaki.”— Nate, Fallout 4
Nagasaki was a city in Japan.
Nagasaki is mentioned in Fallout 4 during the intro, as the last nuclear detonation site to end World War II. The dropping of the bombs on Hiroshima and Nagasaki is the last, known event before the world in which the events of the Fallout series occur, diverges from our own.
- The bomb dropped on Nagasaki was called Fat Man and is likely where the Fat Man weapon derives its name from.
Nagasaki is mentioned only in Fallout 4.
