Mazda is to extend production suspension at its Hiroshima and Hofu plants until 20 March following the huge earthquake that continues to cause extensive disruption across the country.
Previously, operations were scheduled to be stopped from the night shift on 14 March through to the night shift on 16 March.
The Japanese automaker said it would announce any further production changes for 21 March onward as soon as a decision is made.
A statement from the manufacturer said: “Mazda wishes to convey its heartfelt sympathy and concern for all people affected by the major earthquake in eastern Japan.
“Mazda places the highest priority on ensuring the safety and well-being of its suppliers, their employees and their families, in the affected region.”
