Fukui Prefecture will determine whether to restart two idled reactors at Kansai Electric Power Co.'s Oi power plant after consulting the prefectural assembly and the town's residents, Fukui Gov. Issei Nishikawa warned industry minister Yukio Edano on Saturday.

Edano, who together with Prime Minister Yoshihiko Noda and two other ministers agreed Friday that reactors 3 and 4 are safe enough to restart, traveled to the prefecture to drum up public support for the governor.

"It is necessary to use nuclear power as a major source of electricity," Edano told Nishikawa.
