TOKYO Sony Corp said on Friday that two of its plants in northern Japan were halted by a power cut in the region following a powerful earthquake late the previous evening.
The Miyagi prefecture plants, which make optical devices and IC cards, had resumed partial production at the end of last month after being halted by the March 11 earthquake and tsunami.
Sony said production had resumed at a semiconductor laser factory also in the northern prefecture of Miyagi, after being suspended briefly for inspections.
Thursday night's magnitude 7.4 quake shook the devastated coast of northeast Japan and Jiji news agency said two people were killed.
Rival electronics firm Panasonic Corp said it was still confirming the status of its northern Japan plants, all but one of which had resumed operations following the March disaster.
