OSAKA -- A South Korean man filed a lawsuit Wednesday against the Japanese government, seeking compensation for the termination of his medical benefits as an atomic bomb survivor on the grounds that he left Japan to return home, his lawyers said.

Lee Chae Sok, 68, filed the suit with the Osaka District Court. The suit also targets the Osaka Prefectural Government.

In a similar case in June, the district court ordered the state to compensate another Korean atomic bomb survivor.
