In Hiroshima 70 years after the atomic bomb, many survivors' belongings have been inherited: items they wore the day of the bomb, diaries and more. Some families are coming to terms with this legacy for the first time, and want to pass it on. This year Arei Shirakami, age 41, read the diary of her grandfather, who died 17 years ago, for the first time. It shows a side of him she never knew. Feeling regret that she long ignored his story, she makes an emotional journey into her family's past.
