In the interview, he said he has "no doubt" the charges against him - which Nissan says result from a whistleblower operation - were due to "plot and treason" by Nissan executives opposed to plans he was developing to further integrate Renault, Nissan and Mitsubishi.
Mr Ghosn is still being held in a Tokyo detention centre pending trial. And Saikawa, a former protege of Ghosn who led the campaign against his ex-boss, said he intends to step down in coming months after reforming the poor governance he says weakened the Japanese carmaker. The homes were no secret and if they had been a problem, he should have been consulted, Ghosn said.
Ghosn's second bail request was rejected on January 22, with prosecutors fearing that he might tamper with evidence or possibly flee.

Ghosn admitted he was a "strong leader", but argued claims he was a dictator were a distorted version of reality created with "purpose of getting rid of me".
He also defended private properties in Rio de Janeiro, Brazil and Beirut, Lebanon purchased by Nissan for his use as necessary safe places where he could "work and receive people".
Following Ghosn's arrest, France also informed Tokyo of an intention to press ahead with integration.
As well as the allegations which prompted his arrest, Nissan's investigation "uncovered substantial and convincing evidence of misconduct, resulting in a unanimous board vote to dismiss Ghosn and Kelly", he added.
When asked about his health, he said he was "doing fine".More news: E-cigarettes help more smokers to quit
