Toyota Motor Corp. may lose output of at least 40,000 vehicles after Friday's 9.0-magnitude earthquake damaged factories and crippled nuclear power plants, which led to electricity shortages.

Toyota had closed 12 plants across the nation through Wednesday, said spokeswoman Shiori Hashimoto.

Profit for the world's largest carmaker will be cut by ¥6 billion for each day of lost operations, while Nissan Motor Co. and Honda Motor Co. may each lose ¥2 billion a day, Goldman Sachs Group Inc. estimated.
