Toyota Motor Corp., which could lose production of 300,000 vehicles in Japan following earthquake-related shutdowns in that country, expects production to return to normal by the end of the year.

Bloomberg reported that Toyota may lose an additional 100,000 units of overseas auto production through the end of April, according to Executive Vice President Atsushi Niimi.

The carmaker will begin raising production in Japan to regular levels by July. The company plans to ramp up production at overseas plants in August.

Toyota, Honda Motor Co. and Nissan Motor Co. are each working to restore full plant operations in Japan as factories face supply-chain disruptions following a 9.0-magnitude earthquake and an ensuing tsunami that killed nearly 30,000 people.

Niimi said Toyota is unlikely to meet its full-year global production target of 7.7 million units.

Reuters reported that Japan’s cabinet approved today nearly $50 billion of spending for post-earthquake rebuilding. It is expected to be the county’s largest public-works effort in 60 years.
