Today marks 64 years since a nuclear bomb was dropped on the city of Hiroshima killing an estimated 140,000 people. Three days later, another bomb dropped on Nagasaki would kill thousands more.
Pilgrims travel to a monument to Sadako Sasaki near the hypocenter in Hiroshima and decorate it with strands of origami cranes. Sasaki, diagnosed with leukemia, was two when the bomb was dropped on Hiroshima. She folded the cranes in hopes of completing 1,000 cranes (senbazuru) and being granted a wish. She died before she could complete her task, but the cranes folded in her memory carry messages of world peace and nuclear nonproliferation.
