The former chairman of both Renault and Nissan added that while he wanted greater integration between the two auto makers, he wasn't calling for a merger as he desired for the two companies to be run separately.
Combative, spirited, and at times rambling, he described conditions of detention in Japan that made him feel "dead. like an animal" in a country where he asserted he had "zero chance" of a fair trial.
Ghosn said he had received no assurances from the public prosecutor, who has summoned Ghosn for questioning on Thursday.
"I have spent the previous months being interrogated for up to eight hours a day without any lawyers present, without an understanding of what exactly I was being accused of, without access to the evidence that justified this travesty against my human rights and dignity", he said. "There is no way we can overlook this".
Fugitive ex-Nissan CEO Carlos Ghosn is saying his decision to flee Japan, where he was awaiting trial on charges related to alleged financial misconduct, was the most hard choice of his life.
On Wednesday, Ghosn criticized Japan's prosecutors in a fiery press conference - accusing them of brutal treatment and of colluding with top Nissan executives to oust him from the vehicle company.
Ghosn says the charges stem from a "coup" inside Nissan by disgruntled executives and local Japanese officials who feared his plans to more closely integrate the vehicle giant with its alliance partner, French firm Renault.
Japan's Justice Minister Masako Mori earlier Thursday urged Carlos Ghosn to return and make his case in court in Japan.
Ghosn said he was ready to stay for a long time in Lebanon, which does not allow the extradition of its nationals, and a source close to the 65-year-old has said his legal team is pushing for him to be tried in the country.
But Japan and Lebanon don't have an extradition agreement.
One day earlier, with the executive's planned news conference looming, prosecutors also obtained an arrest warrant for Ghosn's wife, Carole, for allegedly committing perjury a year ago.
With the idea of introducing an electronic cable that Japan does not have and that Ghosn proposed as bail, fewer people could be bailed and also electronically monitored. "And some of our Japanese friends thought that the only way to get rid of Renault in Nissan is to get rid of me", he told a room packed with journalists.
The Turkish operator of private jets that Ghosn used to escape Japan said on Wednesday it met with the Japanese ambassador to Turkey and offered to collaborate with the authorities in that country over the incident. He insinuated a plot by Japanese executives to get rid of him because they didn't like how Renault was influencing Nissan.
The Tokyo prosecutors office pushed back on this assertion in a statement issued after Ghosn's roughly 2 1/2-hour news conference ended. Lebanon and Israel are technically at war.
He cited a conviction rate of 99.4 per cent as proof of inherent prejudice of guilt, adding that he was not above the law and would readily stand trial in any country where he could be assured of fairness.
The tycoon holds Brazilian, French and Lebanese nationalities. And in France, Renault alerted French authorities after an investigation found that Ghosn personally benefited from "an exchange worth 50,000 euros" related to a philanthropic accord signed with the Palace of Versailles.
