Nissan refused to comment on the video.
Ghosn awaits attempts at separate charges which he underestimated his income for years and abused his position by transferring personal investment losses to Nissan. He has denied these charges.
"Unless Ghosn can offer evidence that he did not steal from Nissan, his position is untenable," said Stephen Givens, who has practiced law in Japan for more than 30 years.
"If the facts are as proposed, this is devastating to Ghosn," added Givens.
Hironaka told reporters that he would send a special appeal to Japan's Supreme Court on Wednesday, claiming that there was no reason for Ghos's backing.
Ghosn is now back in Tokyo prison where he was held for 108 days until he sent $ 9 million in March. Prosecutors can hold Ghosn until April 24, after which they must accuse or release him.
His arrest and detention have led to the investigation of Japan's judicial system, causing suspects to be questioned without a lawyer. Prosecutors in Japan also have a very high rate of conviction.
Hironaka criticized the treatment of Ghosn on Tuesday.
Lawyers, including former prosecutors, say that human rights abuse complaints will do little to help Ghos's defense when his attempt begins later this year.
Renault revealed new claims against Ghosn last week, claiming that the expenses, in turn, formerly CEO and leader involved "questionable and hidden practices" that violated their ethical rules.
The French car manufacturer also announced Ghosn's departure from the board.
Asked on Tuesday if Ghosn had regretted the nearly 20 years he spent as a leading Nissan, Hironaka said:
He says it's a conspiracy. I think it's something to regret. "
Nissan cut his last remaining bond with Ghosn on Monday when shareholders voted to release him from the board.
