Toyota Motor Corp. said Tuesday its group net profit for the fiscal third quarter jumped 34.1 percent from the previous year to a record 397.5 billion yen thanks to thriving overseas sales and the yen's depreciation against the dollar.

Income before taxes in the three-month period surged 43.1 percent year-on-year to an all-time high of 640 billion yen due to a gain from valuation of shares.

During the October-December period, operating profit rose 14 percent to 482 billion yen while sales grew 14.8 percent to 5.33 trillion yen -- both record highs.
