A black rainbow drawn by a 10-year-old boy who lost his father and sister in the Great Hanshin Earthquake four years ago has become a symbol of the psychological damage suffered by child survivors of the temblor.

The boy, who was buried in the rubble of his house for nine hours, drew the black rainbow several months after the quake, and it was published later that year in a book about young quake survivors.

Now the drawing has become the inspiration for Rainbow House, a facility completed earlier this month to provide a place for children to heal the scars that remain in their hearts.
