Nihon Hidankyo, the Japanese organization of survivors of the U.S. atomic bombings on Hiroshima and Nagasaki, was awarded for its decadeslong activism against nuclear weapons. The survivors, known as hibakusha, see the prize and the international attention as their last chance to get their message out to younger generations.

Now, with their average age at 85.6, the hibakusha are increasingly frustrated that their fear of a growing nuclear threat and push to eliminate nuclear weapons are not fully understood by younger generations.
