Ex-Nissan boss Carlos Ghosn released on bail set at $9m after more than 100 days in detention in Japan.
A Tokyo court made the surprise decision to allow his release on Tuesday, setting bail at 1bn yen (£6.8m; $8.9m).
Mr Ghosn has been charged with financial misconduct and aggravated breach of trust, but denies wrongdoing.
Previous requests for bail were rejected, and his lengthy detention has drawn international criticism.
The 64-year-old left the detention centre surrounded by guards, wearing a cap and white medical face mask.
Strict bail conditions including video surveillance were set as conditions for release.
Mr Ghosn, the architect of the Renault Nissan alliance, brought Mitsubishi on board in 2016.
He ran the alliance of three global carmakers as both chief executive and chairman.
