"I wonder if I can ever have children in the future?"

These words were written in a note from a Fukushima high school girl to 83-year-old Masahito Hirose in the fall of 2011, outlining her worries about the health effects from radiation. The girl and her classmates had visited Nagasaki on a school field trip and listened to Hirose speak about his experiences as a survivor of the 1945 U.S. atomic bombings.

This prompted Hirose to decide to use his own experience of living with the impact of radiation to support young people in Fukushima Prefecture in the long term.
