Ghosn has remained in custody at the Tokyo Detention House since Tokyo prosecutors arrested him on November 19 along with close American aide Greg Kelly, who has been released on bail, for allegedly understating his remuneration in Nissan securities reports submitted to Japanese regulators during a five-year period through March 2015.
Ghosn on Tuesday mounted a systematic denial of all the allegations, concluding that he had been "wrongly accused and unfairly detained based on meritless and unsubstantiated accusations".
Otsuru said his team was applying for bail to have Ghosn released.
Speaking with reporters on Tuesday, Mr Otsuru said he expected prosecutors to take at least six months to prepare for trial.
Following the latest indictment, Ghosn's defense counsel filed a request to the court to seek his release on bail.
The French government has stood by Ghosn so far, saying he must benefit from the presumption of innocence.
He spoke in a strong voice and said he had acted "honourably, legally and with the knowledge and approval of the appropriate executives inside the company".
He said the compensation was never decided on, the investment deal never resulted in any losses to Nissan, and the payments to the Saudi businessman were for legitimate services related to dealers and investments in the Gulf.
Ghosn stands accused of under-reporting his income in documents to investors, apparently in response to criticism that he earned too much. "We are fearful and very anxious his recovery will be complicated while he continues to endure such harsh conditions and unfair treatment", it said. Such visits were canceled Thursday but resumed Friday.
"We believe that there was enough to charge and go to trial", he said of Ghosn's case, "and he will be guilty".
The maximum penalty for the falsifying financial reports and breach of trust is 15 years in prison, 10 million yen ($89,000) fine, or both.
Carlos Ghosn was hit with a third set of charges on Friday.
The charges, which have been widely expected, will add to an earlier charge of under-reporting his income by around half over the five years through March 2015.
Nissan says an internal investigation began in mid-2018 after whistleblowers came forward.
Ghosn then moved his tax domicile to the Netherlands, where the holding company for the Renault-Nissan alliance is incorporated and which does not have a wealth tax, the daily said.
Nissan said Friday it has filed its own criminal complaint against its former chief "on the basis of Ghosn's misuse of a significant amount of the company's funds". The review was initiated after Ghosn was arrested.
