Prime Minister Shinzo Abe said Monday he has plans to unveil a road map this summer on promoting infrastructure-building to allow nuclear evacuees in Fukushima Prefecture to return as early as possible.

"There is a need to create an environment in which each disaster-affected person can visualize when and how the reconstruction will progress," Abe told a press conference on the second anniversary of the disaster that devastated the northeast coastline and triggered the worst nuclear crisis since Chernobyl.

The road map is intended to provide a time frame for when infrastructure, such as power lines and roads, will be restored and when medical and nursing facilities will be ready for resume operation in disaster-hit areas in Fukushima, Abe said.
