The Tokyo District Court said it had approved the request by prosecutors to detain Ghosn until April 14. The decision was widely expected after prosecutors arrested Ghosn for the fourth time at his Tokyo apartment on Thursday.
Ghosn's lawyer, Junichiro Hironaka, told reporters the defence team would file an appeal on Friday against the detention. Prosecutors re-arrested Ghosn on suspicion the former Nissan Motor and Renault SA boss had tried to enrich himself to the tune of $5 million at Nissan's expense.
The latest arrest came some 30 days after Ghosn had been released on $9 million bail from a Tokyo detention centre. Legal experts have characterized the latest arrest as very rare for someone already released on bail. The Ghosn scandal has rocked the global auto industry and shone a harsh light on Japan's judicial system.
Under Japanese law, prosecutors can seek an extension of another 10 days of detention before they must either bring formal charges against the suspect or let him go.
