TOYOTA CITY, Japan — Toyota Motor said Monday it will shut down all of its North American factories due to parts shortages caused by last month’s earthquake and tsunami in Japan, Business Insider reported.

The shutdown is temporary and will affect about 25,000 workers. Toyota gets about 15 percent of its parts from Japan.

The length of the shutdown is unknown and depends on how fast Japanese parts factories can get back in operation.

Last week, Toyota warned its US dealers that they face a shortage of some replacement parts after many of the company’s plants in Japan sustained significant damage from the March 11 earthquake and tsunami.

Honda Motor Co. and Subaru of America said they would curb US assembly operations to conserve parts as well.

Toyota said production of most replacement parts resumed in Japan on March 17, and shipments to the US restarted shortly after that.

However, the company has also identified 233 replacement parts that are made by suppliers who have not yet been able to resume operations.

Production of these parts will not resume for “at least 30 days,” the company said in a memo to dealers last week. It added that “both the number of affected parts and length of production stoppage may increase.”

In recent trading Toyota shares fell 1.1 percent to $79.63.
