For Hiroshima survivor, 70th anniversary rekindles memories of terror, taboos
It was a warm summer morning, and five-year-old Yukiko Nakabushi was the first to arrive at nursery school. She sat playing quietly as she waited for her friends to come through the door. Except they never arrived.
Instead, at precisely 8.15am, she saw a sudden flash accompanied by a deafeningly loud bang - and in an instant, the world's first atomic bombing transformed the Japanese city of Hiroshima into a living hell.
Mrs Nakabushi (76) is one of the nation's remaining 183,519 survivors of the 1945 bombing - known as hibakusha - for whom the events of that exact moment are etched in their memories with haunting clarity.
