Mori told reporters at the ministry action has already been taken to prevent a recurrence, while declining to give details. It is established with the proper procedures and is operated in an appropriate manner.
She acknowledged the case was being looked at under an ongoing review of the nation's judicial system, including introducing electronic tethers to monitor those out on bail.
Japan's justice ministry said it did not have records of Mr Ghosn departing Japan. Preparing for his trial has taken about a year, and a date has not been set. He has denied all charges, but said Japan's system won't afford him a fair trial.
"Simple comparisons are misleading", she said.
The Wall Street Journal said Mr Ghosn was loaded on to the private jet bound for Turkey in a flight case, more normally used to transport musical equipment for live shows, with holes drilled into the bottom so that the fugitive executive was able to breathe. It took the Japanese carmaker, which Ghosn virtually saved from bankruptcy almost two decades ago, more than a week to issue an official statement on the matter. Ghosn's lawyer, Junichiro Hironaka, added that he was "surprised and baffled" by the reports surrounding his escape - the exact circumstances of which are still, it seems, uncertain. But the Turkish airline MNG Jet has said that two of its planes were used illegally, first flying from Osaka, Japan, to Istanbul, and then to Beirut, where it arrived last Monday and has not been seen since.
Lebanon has said he entered legally with a French passport.
Treasury announces boost to National Living Wage
Guaranteed minimum pay is among a series of worker protections that we have put in place in New Jersey . But we did see an increase in the earnings earned by workers ". "They just take that out", Chen said.
The Lebanese government has stood behind Ghosn, with some reports saying that he met with Aoun shortly after his arrival.
Japan has launched a probe into the humiliating security lapse and prosecutors said they would "coordinate with the relevant agencies to swiftly and appropriately investigate the matter".
In a statement released by Nissan earlier today, the carmaker called Ghosn's widely publicized getaway an "extremely regrettable" incident, adding that the company will continue to aid authorities in brining its former executive to justice. He managed to skip bail and leave the country despite heavy surveillance while he was staying at a home in Tokyo.
Ghosn had been accused of not reporting his future compensation and abuse of trust by diverting Nissan's money for personal gain. He insists he is innocent.
His bail has been revoked, and Interpol had issued a wanted notice.
Chief Cabinet Secretary Yoshihide Suga said on Monday night that Japan will make every diplomatic effort to get Lebanon to hand over Ghosn to the Japanese authorities.
Ghosn was due to appear before Tokyo courts in the coming months in connection to charges of financial irregularities during his tenure at the helm of Nissan Motor. It has extradition treaties only with the USA and South Korea, meaning it might be hard to return Ghosn from Lebanon.
