An exhibition featuring the U.S. atomic bombings of Hiroshima and Nagasaki opened Saturday in Los Angeles, telling the stories of Japanese Americans who were in the two cities when the bombs were dropped in August 1945.

Marking the 75th anniversary of the bombings, the Japanese American National Museum will run the event through next June 7 in partnership with the cities of Hiroshima and Nagasaki.

During an opening event, Junji Sarashina, 90, a second-generation Japanese American who was in Hiroshima at the time of the bombing, said he hopes all future generations will learn about the horrors of atomic bombs through the exhibition.
