What is the meaning of paper crane?

The paper crane is a symbol of peace, hope, and healing, particularly in Japanese culture. It is often associated with the legend that folding a thousand origami cranes grants a wish or brings good fortune. The crane's significance was further popularized by the story of Sadako Sasaki, a young girl who folded cranes while battling leukemia from radiation exposure after the Hiroshima bombing. In this context, the paper crane embodies the desire for peace and a world free from suffering.
