Children's Peace Monument Research Questions

This monument is dedicated to Sadako, a young child who died of leukemia from the radiation of the A-Bomb. The monument was based on her story; she believed that if she folded 1000 cranes that she would be healed. I was wondering if there were any other reasons for her being chosen for the monument other than her 1000 crane story. Also, the number 1000 itself seems very specific as well and I wanted to research what the number's significance to Japan's culture was. The way the monument is set up is architecturally innovative and I wanted to analyze how the structure reflected Sadako or the message she was giving. This moneument is very different than the other monuments in Hiroshima's peace park, and I wanted to discover why they made is so interactive and if that affects its fame.
