~Letters from Hibakusha~ On August the 6th, 1945, an Atomic Bomb was dropped on Hiroshima. NHK Hiroshima Broadcasting Corporation sent out an appeal for accounts from Atomic Bomb survivors. 2,200 letters arrived. It is now 76 years since the bomb was dropped and the survivors are growing older and older. In order to communicate their stories to the younger generations, these letters have been used to make animations.
