masya89 [10]

Answer:

Sadako and the Thousand Paper Cranes is based on the true story of a girl named Sadako Sasaki. It begins nine years after the United States dropped an atom bomb on the city of Hiroshima, Japan in an attempt to end World War II. When the bomb fell, Sadako was only two years old, and she survived the explosion with seemingly no injuries.
