The company raised its full-year operating profit forecast to 700 billion yen from 500 billion yen, and said it expected the yen to trade at an average rate of 140 per dollar, five yen weaker than it had previously estimated.

Toyota Motor and Honda Motor are expected to report weaker first-quarter earnings this week, as U.S. import tariffs and a stronger yen weigh on profits despite solid demand for hybrids in their biggest overseas markets.

First-quarter profit halved from a year earlier due in part to the U.S. levies, though the automaker raised its annual earnings forecasts, citing a smaller-than-feared tariff hit.
