Lee Sil Gun, a 77-year-old Korean living in Hiroshima, has struggled for the past 30 years to help North Korean atomic bomb survivors yet to receive any government support due to the lack of diplomatic ties with Pyongyang.
Lee has never given up, even during the time when North Korea had yet to admit the existence of atomic bomb victims.
But recently his efforts have hit a snag amid heightened tensions over North Korea's recent missile launches.
