The nuclear crisis in Fukushima continues to extend its reach months after the March 11 disaster, with the latest repercussion hitting working parents across Japan who will be forced to work on weekends to save electricity but when day care centers are normally closed.

Prompted by urgent requests from those parents, major manufacturers nationwide planning to operate on weekends are scrambling for solutions so their employees can work without worrying about their children.

"We are in a rush to make it on time . . . but we'll probably need to make adjustments as we proceed," Takeshi Kawakami, a Hitachi Ltd. spokesman, told The Japan Times.
