Toyota Motor Corp. said on Tuesday that it would suspend production at all of its domestic plants for 11 days between February and March in response to a slump in sales.
"We will suspend the operation of 12 Toyota factories in Japan for 11 more days," a Toyota spokesman said.
Japan's top automaker is already idling its domestic plants for three days in January to cope with rapidly worsening demand.
The latest output cuts came after the Japanese auto giant last month forecast its first-ever annual operating loss, blaming "an unprecedented crisis" in the global auto industry.
Toyota has already moved to reduce production at its domestic, US, Canadian and French factories, and plans to lay off 3,000 temporary workers in Japan.
The global slowdown has badly shaken Japan's automakers, which in recent years have cashed in on worldwide demand for their cars.
Toyota's troubles underscore the deepening woes plaguing the auto industry, which has forced the Big Three US automakers to seek financial lifelines from the US government to stave off bankruptcy.
