Ghosn, who has not spoken publicly, told investigators that he had no intention of under-reporting his salary on financial documents and has denied allegations against him, NHK said on Sunday, without giving sources.

At the Tokyo close, Nissan was up almost two percent and Mitsubishi Motors enjoyed an even sharper bump - up more than three percent just ahead of the board meeting.
Nissan removed Ghosn at a high-stakes board meeting on Thursday after alleging he understated his income and used company money for personal use.
Renault, for its part, has launched an investigation into possible misconduct by Ghosn in relation to his remuneration and company assets, with the outcome expected as early as this week, according to Le Maire. And Nissan is nearly 60 percent bigger than Renault by sales. Renault owns about 43% of Nissan with voting rights, while the latter holds a non-voting 15 percent in the French maker. Mitsubishi CEO Osamu Masuko will assume the role of temporary chairman.

With Ghosn gone, Nissan's Saikawa is already plotting a review of the alliance to make it more equitable, according to people familiar with the plans. "Masuko has made it clear the future of the alliance is important to them and they will go along with supporting Nissan".
A small team involving Nissan's board members carried out its internal probe confidentially on concerns about possible destruction of evidence by Ghosn, Japan's Kyodo News reported, quoting unnamed sources.
According to the Financial Times, Ghosn was reportedly planning to strengthen a partnership between Nissan and Renault at the French government's request, despite the Japanese firm's strong reservations about it.
Carlos Ghosn has hired USA -based law firm Paul, Weiss, Rifkind, Wharton & Garrison to defend himself against allegations of financial misconduct in Japan, a person familiar with the matter said.
In an address to Nissan's global employees Monday, Saikawa said Ghosn held too much power at the company.
His close aide Greg Kelly, who is also under arrest in the same case, has told an individual who met him in detention that Ghosn's "executive remuneration was properly listed in the financial statements" submitted to the authorities.
Japanese prosecutors arrested him on suspicion of underreporting his compensation at Nissan by about $44 million (U.S.) over a five-year period.
France's economy minister Bruno Le Maire has urged the Japanese firm to share "quickly" whatever evidence it has gathered and stressed Ghosn will stay at the helm of Renault "until there are tangible charges".
