The visiting French delegation is seeking an explanation from Nissan's management regarding its corporate governance in the wake of Ghosn's arrest, the Nikkei business daily reported, without citing sources.
Nissan Motor Co. and Mitsubishi Motors Corp. said Friday their own investigation found that ousted Chairman Carlos Ghosn received about 7.82 million euros ($8.9 million) "illegally" from the two firms' overseas joint venture.
Nissan said in a statement that it viewed Ghosn's payments as "the result of misconduct, and will consider measures to recover from Ghosn the full sum".
"The most likely charge for this would be embezzlement", he told reporters at a briefing.
The unit had been meant to fund expenses for the partnership including consultant fees, joint promotional activities, workspace use and corporate jets, Masuko said.
Ghosn's lawyer, Motonari Otsuru, could not be immediately reached by telephone for a comment on Friday.
Ghosn, arrested and detained in Tokyo since November 19, has been indicted in Japan on charges of under-reporting his salary for eight years through March 2018, and temporarily transferring personal investment losses to Nissan Motor during the global financial crisis.

Ghosn was arrested on 19 November on charges of financial misconduct and faces a lengthy criminal trial.
The Japanese newspaper "Nikkei", according to Renault, want to meet executives and French government representatives on this Thursday, Nissan's chief Hiroto Saikawa in Japan. He was the chairman of both Nissan and Mitsubishi but was removed from the positions after his arrest.
Renault wanted to find "the best solution for the future leadership of the group, in order to safeguard the interests of the company and to strengthen the Renault-Nissan Alliance", said the group.
Renault, which is expected to soon call a board meeting to choose a successor to former auto titan Ghosn, sold 3,884,295 vehicles a year ago, a 3.2 per cent increase over 2017, putting it ahead of French rival PSA Peugeot Citroen.
Renault's sales rose to a record 3.88 million vehicles a year ago - including some 166,000 sold through its new partnership with China's Brilliance. He has also been in news previously for hidden bonus plans.
The French automaker holds around 43% of Nissan, the biggest partner in the alliance by sales and which in turn holds a non-voting 15% stake in Renault.
