As Japan's legal system faces international scrutiny over its treatment of defendants amid the Carlos Ghosn saga, there is a silver lining to be found for critics: the rising number of suspects being granted bail.

The 65-year-old former Nissan Motor Co. chairman was released late Thursday night after posting bail of ¥500 million.

Ghosn's prolonged detention — 108 days between Nov. 19 and March 6, when he was released on bail for the first time — and treatment, including interrogation without his lawyers present, have unleashed international criticism toward the country's legal system, with some critics labeling it "hostage justice."
