In August 1955, she was moved into a room with a girl named Kiyo, a junior high school student who was two years older than her. Shortly after, cranes were brought to her room from a local high school club. Sasaki's friend, Chizuko Hamamoto, told her the legend of the cranes and she set herself a goal of folding 1,000 of them, which was believed to grant the folder a wish. Although she had plenty of free time during her days in the hospital, Sasaki lacked paper, so she used medicine wrappings and whatever else she could scrounge; including going to other patients' rooms to ask for the paper from their get-well presents. Her best friend, Chizuko, also brought paper from school for Sasaki to use.
