After Sasaki Sadako's death (12 years old), a campaign started, commemorating the spirits of children victims of the A-bomb and raising funds to build a memorial for Sadako and all of the children who died from the effects of the atomic bomb. Later, the news spread over the world, and people from all over the world visit the "Children's Peace Monument" to lay down folded-paper crane around the monument. The number of paper crane put down is over 10 million annually. A bronze girl who holds a gold crane is standing on the top of the tripodal domed statue, and located next to the domed statue, there are the statues of boys and girls symbolizing bright future and hope.
