Sadako and the Thousand Paper Cranes is a non-fiction children's book written by American author Eleanor Coerr and published in 1977.
This true story is of a girl, Sadako Sasaki, who lived in Hiroshima at the time of the atomic bombing by the United States. She developed leukemia from the radiation and spent her time in a nursing home creating origami (folded paper) cranes in hope of making a thousand of them. She was inspired to do so by the Japanese legend that one who created a thousand origami cranes would then be granted a wish. Her wish was simply to live. However, she managed to fold only 644 cranes before she became too weak to fold any more, and died shortly after. Her friends and family helped finish her dream by folding the rest of the cranes, which were buried with Sadako. They also built a statue of Sadako holding a giant golden origami crane in Hiroshima Peace Park.
Now every year on Obon Day, which is a holiday in Japan to remember the departed spirits of one's ancestors, thousands of people leave paper cranes near the statue. On the statue is a plaque: "This is our cry. This is our prayer. Peace on Earth."
The book has been translated to many languages and published
