Nearly 42 percent of atomic bomb survivors living abroad are not satisfied with the Japanese government's support measures, according to a Kyodo News survey conducted ahead of the 70th anniversary of the U.S. atomic bombings of Hiroshima and Nagasaki.

Some overseas survivors have taken legal action, hoping they would be granted full medical coverage that is given to survivors living in Japan.

The survey was conducted in June and July through questionnaires sent by mail or interviews, covering about 210 atomic bomb survivors residing overseas. A total of 117 people — 50 in South Korea, 29 in the United States and 38 in Brazil — responded.
