Feb 6 (Reuters) - Toyota Motor raised its full-year operating profit forecast on Friday, as it expects a weak yen and cost reduction efforts to lift its results.

The world's biggest automaker now expects operating profit of 3.8 trillion yen ($24.26 billion) for the year to the end of March, up 11.8% from its previous outlook of 3.4 trillion yen.
