Last month, Mr. Ghosn and Nissan itself were indicted on charges that they had withheld millions of dollars of his income from Nissan’s financial filings for years when he was both chairman and chief executive of the company.

Mr. Ghosn and his lawyers portrayed him on Tuesday as a dedicated executive committed to overseeing the alliance. His actions, they said, were disclosed to and approved by other company officials. In his statement to the court, Mr. Ghosn said he had “never received any compensation from Nissan that was not disclosed.”



Late last month, he was rearrested on the allegations that he had improperly transferred investment losses to Nissan, and his detention was extended.

Mr. Otsuru said at a news conference that Nissan’s own board minutes showed the company had agreed that Nissan would temporarily provide collateral for Mr. Ghosn when he incurred deep paper losses on foreign exchange investments after the financial crisis of 2008.

The board minutes have not been publicly released.

In a statement submitted to the court for the hearing on Tuesday, Mr. Ghosn’s defense lawyers described the board minutes as authorizing a Nissan “secretarial section” to enter into foreign exchange contracts “for the benefit of non-Japanese corporate officers and directors at no cost to the company.”

Mr. Ghosn, the statement said, had asked the board to pass a resolution with general language that did not specifically include his name so that “he would not have to explain the situation where he had to pay for significant losses” as the “suspect, if possible, did not want to have all of the people attending the board meeting to know that he had incurred significant valuation losses.”
