Extradited to Japan from the US in March, they are being held at the same jail in Tokyo where Ghosn was imprisoned. They could face up to three years in prison.
Wearing black jackets and pants, white shirts and plastic slippers, the duo were led into the court with ropes threaded through handcuffs and tied around their waists.
Prosecutors accused them of helping Ghosn evade punishment and escape to Lebanon from western Japan’s Kansai airport, receiving $1.3m for their services, some of which was paid to an advertising company owned by the younger Taylor. The Americans asked Ghosn for another $500,000 for legal fees after Japan sought their arrest, prosecutors said.
