A. "Origami" paper cranes can be seen throughout the city. They became a symbol of peace because of a 12-year-old bomb survivor, Sadako Sasaki, who, while battling leukemia, folded paper cranes using medicine wrappers after hearing an old Japanese story that those who fold a thousand cranes are granted one wish. Sadako developed leukemia 10 years after her exposure to radiation at age 2, and died three months after she started the project. Former U.S. President Barack Obama brought four paper cranes that he folded himself when he visited Hiroshima in May 2016, becoming the first serving American leader to visit. Obama's cranes are now displayed at the Hiroshima Peace Memorial Museum.
