Shares of Toyota Motor Corp fell 0.5 percent early on Friday after the world's largest carmaker reported better-than-expected quarterly results the previous day and raised its outlook despite the ongoing recall turmoil.

Investors were also digesting a report by the Nikkei business daily that Toyota may recall an estimated 270,000 units of its flagship Prius hybrid in the United States and Japan to fix a brake problem.

The stock fell to 3,265 yen, after dropping 3.5 percent to a 10-month low on Thursday.

Toyota said on Thursday that the recall of more than 8 million vehicles due to problems with unintended acceleration on conventional gas-powered vehicles would cost it up to $2 billion in the January-March quarter.
