A popular fictional version of the tale is that Sadako folded 644 cranes before she died; her classmates then continued folding cranes in honor of their friend. This version of her story has been refuted by the Hiroshima Peace Museum and her family. She was buried with many cranes, folded both by Sadako herself and her classmates. While her effort could not extend her life, it moved her friends to make a statue of Sadako in the Hiroshima Peace Park. Every year 10,000,000 cranes are sent to Hiroshima and placed near the statue. A group of one thousand paper cranes is called "senbazuru" in Japanese (千羽鶴).
