The automaker said it still remained unclear when the company can return to full production in Japan. Toyota spokeswoman Shiori Hashimoto said the company will decide later on production plans after June 6.

Toyota is currently shutting down Japanese output except at three plants, which are running at limited capacity.

It will resume production at all its Japanese plants at half capacity from April 18 to 27, and then halt output from April 28 to May 9, a period that includes Golden Week holidays when factories would normally close.
