Prosecutors in Tokyo issued new indictments for Carlos Ghosn on Friday (January 11) on two new charges of financial misconduct.
The former Nissan chairman was once an auto industry superstar, praised for rescuing the company from bankruptcy.
Now prosecutors say he could face up to 15 years on prison.
He's now been officially charged over temporarily transferring investment losses to Nissan in 2008 and for understating his income from 2015 to 2017.
He's been detained in Tokyo since his arrest in mid-November.
Friday's indictments add to an already-existing charge for Ghosn of misrepresenting his income for a five year period leading up to 2015.
At the same time, Nissan itself along with former executive Greg Kelly were also indicted for under-reporting Ghosn' income.
Ghosn's legal team said they've also applied for bail for their client, but in Japan it's uncommon for defendants who've denied their charges to be granted bail before trial.
On Tuesday (January 8) Ghosn declared his innocence in a Tokyo court, calling the allegations meritless and unsubstaniated.
That was his first public appearance since last year's arrest.
At a press conference the same day, Ghosn's legal team disputed the criminal nature of the case and expressed their concern over his health after weeks in detention.
Also saying Ghosn may have to endure many more months of similar conditions before trial.

I'm afraid it will take at least another six months until the first trial takes place." Also on Friday (January 11) Nissan canceled the lease on Ghosn's luxury Tokyo apartment as the automaker tries to cut ties with their former chairman.
