Japanese prosecutors on Thursday said they will detain former Nissan chairman Carlos Ghosn for as long as is needed to finish their investigation into suspicions of financial irregularities, as the Renault-Nissan-Mitsubishi alliance reaffirmed its partnership.
Shin Kukimoto, deputy chief prosecutor for the Tokyo District Public Prosecutors’ Office, defended its handling of Mr. Ghosn, who was arrested on Nov. 19 along with another Nissan executive, Greg Kelly.
“We are not detaining (Ghosn) for an unnecessarily long time,” Mr. Kukimoto told reporters. “We only take necessary steps as needed.”
Mr. Kukimoto refused to confirm reports that both Mr. Ghosn and Mr. Kelly denied the allegations against them. Mr. Ghosn is suspected of violating financial laws by underreporting millions of dollars in income and Mr. Kelly of collaborating in that. Nissan has also said an internal probe triggered by a whistleblower found Ghosn allegedly misused company assets.
Japanese automakers Nissan Motor Co. and Mitsubishi Motors Corp. have since dismissed Mr. Ghosn as their chairman. Renault SA of France has named an interim chairman but kept him on while seeking more information about his case.
Last week, prosecutors obtained a court’s approval to keep Mr. Ghosn until Friday, in line with standard investigative procedures in Japan, Mr. Kukimoto said. After an initial investigation period, Japanese authorities can detain a suspect up to 20 days per charge, and gain more time by adding more charges.
“Japan is a law-abiding country and this is the way our justice system works. I don’t see any problem with that,” Mr. Kukimoto said. “Each country has its own history and culture ... It is not appropriate to criticize a system in another country just because it’s different from your own.”
Prosecutors are expected to obtain a court’s permission Friday to keep Mr. Ghosn and Mr. Kelly in custody for another 10 days, until Dec. 10. Mr. Kukimoto declined to comment on that.
The arrest and detention of such a prominent businessman is shedding light on Japan’s pre-indictment detention of suspects, even those suspected of financial crimes, which has long drawn criticism from human rights activists.
Lebanon, where Mr. Ghosn is from, said in a statement on Thursday that Foreign Minister Gebran Bassil summoned Japanese Ambassador Matahiro Yamaguchi in Beirut and asked for a fair and transparent investigation that met international standards and allowed Mr. Ghosn to communicate with his family and lawyers. Mr. Kukimoto said Mr. Ghosn can meet with his lawyers and embassy envoys, but is not allowed to have his lawyer present during questioning.
At the time of his arrest, Mr. Ghosn was heading the Renault-Nissan-Mitsubishi alliance, which says it sold more than 10.6 million vehicles in nearly 200 countries in 2017.
Mr. Ghosn’s legal predicament has raised speculation about troubles within the alliance.
On Thursday, the automakers issued a statement saying member companies had individually and collectively “emphatically reiterated their strong commitment” to their partnership.
