Japanese automakers are buckling up for U.S. tariffs that might cost them hundreds of billions of yen a year; when all added up across the industry, maybe more than ?1 trillion ($6.8 billion) in total.

The major carmakers, all of which had released earnings for the last fiscal year by Wednesday, said it¡¯s tough to factor the changing tariff situation into their forecasts, but they expect the new levies will cost them a lot no matter what happens.

Some manufacturers have indicated an intent to increase production in the United States.
