Mario Kart 8 has sold two million copies to date worldwide, according to reports.
The news comes from Nintendo's 74th Annual General Meeting of Shareholders, in which the company held a Q&A session for its shareholders to enquire about the company's last financial year.
While the full transcript of the meeting has yet to be published by Nintendo, a tweet from a shareholder in attendance reported that the company's general hardware manager Genyo Takeda stated that Mario Kart 8 had sold two million copies worldwide since its release in late May.
Takeda went on to say that Wii U hardware sales had also increased as a result, though according to reports he did not provide any figures.
In March 2014, Nintendo reported it had sold 6.17 million Wii U units to date. Though it has yet to reveal updated figures in the wake of Mario Kart 8 sales, this suggests a remarkable attach rate for the game with just under one in three Wii U owners buying it.
The meeting was held by Takeda and Shigeru Miyamoto, with president Satoru Iwata unable to attend due to recovery from surgery on his bile duct.
Iwata did not attend this year's E3 conference in LA due to unspecified health reasons. It would now appear the surgery was the reason for this.
Nintendo swung to an annual net loss in the financial year ended March 31 2014 as Wii U sales continued to disappoint.
However, recent strong sales of Mario Kart 8 and a positively received E3 suggest the company has the potential to slowly turn around its fortunes.
