Tokyo - The trial of Carlos Ghosn, the former head of Nissan who has been charged with financial misconduct in Japan, will begin as early as March, Kyodo News said on Thursday, citing his defence lawyer.
Ghosn, once one of the world's most celebrated motor industry executives, was arrested in Tokyo in November, and faces charges including improperly enriching himself at a cost of $5 million (R73.7m) to the carmaker. He has denied any wrongdoing.

He has been released on bail, but Japanese courts have dismissed his appeals to ease a bail restriction that bans him from contacting his wife. His lawyers have argued that condition violates Japan's constitution and international law on family separations.
Executive pay scandal
Meanwhile Nissan was embroiled in another scandal over executive pay on Thursday after Chief Executive Hiroto Saikawa admitted to being overpaid in violation of internal procedures under a scheme designed by ousted Chairman Carlos Ghosn.
An internal investigation found that Saikawa and other executives had received improper compensation, a source with knowledge of the matter told Reuters, raising doubts about Saikawa's pledge to improve governance in the wake of Ghosn's arrest last year for alleged financial misconduct.
Saikawa apologised and vowed to return any improperly paid funds as he admitted to Japanese reporters earlier on Thursday that he had wrongly received stock-related compensation under "a scheme of the Ghosn era".
"I am deeply sorry for causing concern," Saikawa said, according to Jiji Press.
In other comments reported by Kyodo news, Saikawa denied any direct role in the execution of the rights scheme and said he thought "proper procedures" had been taken.
The improper payments, including tens of millions of yen Saikawa received through a stock appreciation rights (SAR) scheme, were disclosed on Wednesday at a meeting of Nissan's audit committee, said the source who declined to be identified because the information is not public.
Disciplinary action regarding the issue would be discussed at an upcoming board meeting, the source added.
Nissan said in a statement that the findings from its probe including issues related to the share appreciation rights would be submitted to its board on Sept. 9.
The company has been trying to strengthen governance, slash costs and boost flagging profitability amid persistent allegations of financial misconduct stemming from Ghosn's 20-year reign at Japan's second-biggest carmaker.
Confidence in Saikawa had already been shaken by accusations he was too close to Ghosn, whose arrest in November rocked the global auto industry and exposed tensions in the automaking partnership between Nissan and Renault SA.
The company launched its internal investigation after Japanese magazine Bungei Shunju in June published accusations by former director Greg Kelly that Saikawa was granted an exception in 2013 to reschedule a stock-linked bonus that bumped up the payout by 47 million yen.
Like Ghosn, Kelly is awaiting trial on charges of financial misconduct.
The latest compensation issue could exacerbate tensions with top shareholder Renault SA, after a failed attempt by the French automaker to secure a full merger with Nissan and to combine Renault with Fiat Chrysler (FCA). Saikawa has opposed both plans.
"Saikawa should resign once the misconduct is formally reported to the board," Nobuo Gohara, a lawyer who heads Gohara Compliance and Law Office, which is not involved in the Ghosn case, wrote in a blog on his website.
The CEO was re-appointed by shareholders with the lowest approval rating among the 11 directors in June.
