Nissan late last month upgraded its full-year operating profit forecast, raising it by 30 billion yen ($208 million) to 550 billion yen.
About 20 billion yen of that came from the currency, CFO Stephen Ma told a briefing.
At smaller Subaru (7270.T), a move of one yen against the dollar has a 20 billion yen impact on operating profit, CFO Katsuyuki Mizuma said earlier this month.
On Wednesday, a Honda official said its April-June operating profit came in tens of billions of yen higher than expected, with the weak yen accounting for about half of that.
It is unclear how long the weak yen will last.
