The Nov. 19 arrest of ousted Nissan Motor Co. Chairman Carlos Ghosn, his 23-day detention, his subsequent arrests and lengthy stay in detention has resulted in international scrutiny of Japan's criminal justice system. Is that fair?

Shin Kukimoto, deputy public prosecutor at the Tokyo District Public Prosecutor's Office, defended the practice at a news conference in the capital last year.

"Each country has its own history, culture and systems," Kukimoto told reporters. "I wonder if it's appropriate to criticize our system just because it's different."
