The Osaka District Court on Thursday revoked the 2011 Osaka Prefectural Government's decision not to cover the medical costs of a South Korean who survived the Hiroshima atomic bombing and received treatment in South Korea, and two other Koreans.

Under the 1994 atomic bomb survivors' relief law, the government covers all the medical expenses for people who suffered due to the atomic bombing and received treatment in Japan. Thursday's ruling could pave the way for atomic bomb survivors living outside Japan to receive full coverage as provided to residents in the country.

The plaintiffs include the 67-year-old survivor and two relatives of two now-deceased people whose health was damaged by the atomic bombing of Hiroshima. Details pertaining to their identity, gender or place of residence after the bombing were not provided.
