The massive 8.9 magnitude earthquake and tsunami that hit Japan on Friday has implications for the car industry.
Toyota Motors, the world's biggest auto maker has suspended operations at all of its 12 Japanese factories.
The company said production will be halted at least until Wednesday, reducing output by 40,000 vehicles.
Japanese factories account for 38% of Toyota's overall production.
Japan's third-largest auto maker, Honda, has also suspended operations.
The company makes about a quarter of all its cars in Japan.
Toyota, Honda and Nissan Motor Company reported damage to more than a dozen plants and facilities, mostly in and around the hardest-hit Tohoku region, more than 200 miles north of Tokyo.
Nissan said 1,300 United States-bound vehicles were damaged at the port of Hitachi, north of Tokyo, and another 1,000 at the Miyagi Service Center suffered damage when the tsunami swept ashore.
Honda said the disruptions in Japan would not have an immediate impact on its North American operations, which produce 90% of the vehicles it sells in the United States.
The majority of Toyota's US sales also are produced in North America.
Japan stock market fall
And the Bank of Japan has pumped a record US$85 billion of emergency funds into its financial system to try to provide stability following the earthquake and tsunami.
Stock markets fell sharply when they reopened for the first time on Monday following the disasters.
The benchmark Nikkei Share Index fell 6.18% in the first 20 minutes of trading.
Production was stopped at some of Japan's best-known companies, heavily denting their share prices.
