Toyota says its net profit soared 93.6 per cent in the three months to June and added that it was on track to produce more than 10 million vehicles worldwide this year.
The world's biggest car maker earned Y562.19 billion ($A6.35 billion) in the quarter on sales of Y6.25 trillion, which were up 13.7 per cent from a year earlier.
Toyota credited a sharp decline in the yen among the factors for its improved results.
"Operating income increased due to the impact of foreign exchange rates and our global efforts for profit improvement, through cost reduction activities," managing officer Takuo Sasaki said in a statement on Friday.
The company added that it expects a net profit of Y1.48 trillion for the fiscal year to March on sales of Y24 trillion.
That was up from an earlier forecast of a Y1.37 trillion profit on sales of Y23.5 trillion.
