Three students at a university in Hiroshima are making a 20-minute documentary about residents in the city who were exposed to radioactive “black rain” after the 1945 atomic bombing.

The trio from Hiroshima University of Economics, who at the start of making the film didn't know much about victims of the black rain, listen to the hardships residents in Saeki Ward have endured over the years, with the victims complaining of health problems caused by internal radiation exposure and being denied financial support by the government.

The students' hope, as they put it, is to "create a film that will inspire the younger generation, who feel that the war and the atomic bombing are something unrelated to them."
