Why it matters: Origami Day, celebrated on November 11, honors the rich tradition of Japanese paper folding, reflecting both artistic expression and mathematical principles.

Ways to celebrate

The paper crane became a global peace symbol because of one sick child's determination. Sadako Sasaki, a Hiroshima girl who developed leukemia at age 12 from radiation exposure as a toddler, began folding paper cranes in her hospital bed after hearing a legend that folding 1,000 would grant a wish — she folded over 1,300 before her death in 1955, and children across Japan later raised money for the Children's Peace Monument built in her memory.

Fold a crane of your own

  • Learn the traditional crane fold, the same design Sadako used, from a diagram or video, and try folding several from small squares of paper.

Go beyond the crane

  • Try a second traditional fold — a box, a boat, or a simple flower — to see how the same handful of basic folds combine into very different shapes.

Did you know?

Hiroshima's Children's Peace Monument, topped with a statue of Sadako holding a golden crane, is still surrounded by donated paper cranes sent from people and school groups around the world as an ongoing tribute.
