The United States and Japan have an extradition treaty, but Lebanon and Japan do not.
Ghosn, who was awaiting trial in Tokyo on financial-crime charges, jumped bail and slipped out of the country in late December aboard a private jet bound for Lebanon.
An executive from Turkish private jet operator MNG Jet and four pilots were detained in early January soon after Ghosn's escape and charged with migrant smuggling, a sentence carrying a maximum sentence of eight years in jail.
The Taylors were arrested in Harvard, Massachusetts as the son was preparing to travel to Lebanon, where Ghosn fled after sneaking out of Japan.
They have been forbidden from travelling overseas.
Authorities claim the Taylors helped sneak Ghosn out of Japan on a private jet with the former Nissan boss tucked away in a large box.
The two flight attendants, who were not under custody, face a one-year prison term each if convicted of not reporting a crime. They are free pending trial.
The pilots and flight attendants deny the accusations.
The men - security contractor and former U.S. special forces member Michael Taylor and his son Peter - were taken into custody on May 20 after they were named earlier in a Japanese arrest warrant for participating in Ghosn's dramatic escape.
The indictment said the MNG employee received several payments into his bank account totalling over 250,000 euros in the months before Mr Ghosn's flight.
But during the hearing, Kosemen denied being paid to help Ghosn escape while the pilots and flight attendants said they were unaware he was on board any flight.
Kosemen said that a business associate named, Nicolas Mezsaroz, who organised the flights called him through a messaging app to say that the Nissan chef executive was on board the plane from Osaka.
A photograph provided by Istanbul Police Department shows the case which the former Nissan chief allegedly hid in while fleeing from Japan.
"The situation freaked me out", Kosemen said, quoted by Anadolu, after Mezsaroz apparently told him on the phone that he knew where the employee's wife worked and where his child went to school.
The company said at the time that its employee had admitted to falsifying flight records so that Ghosn's name didn't appear on them.
