Former Nissan chief Carlos Ghosn said on Wednesday he had been treated brutally and ruthlessly by Japanese prosecutors, who threatened to take action against his family if he didn’t confess to their accusations.

The recent removal and arrest of Carlos Ghosn, chairman of car maker Nissan is another corporate scandal to tarnish Japan Inc. in recent years, and once again raises fundamental questions about governance in the country. While some of the issues are deep-rooted and would require a serious change of mindset, senior in-house counsel can play their part in improving the culture going forward.

Three-quarters of Japanese companies have no plan to create committees overseeing compensation or executive nomination, a Reuters poll found, reflecting indifference to boosting governance after the arrest of former Nissan boss Carlos Ghosn.

Carlos Ghosn, the recently ousted chairman of Japan’s Nissan Motor Co., has hired U.S. law firm Paul, Weiss, Rifkind, Wharton & Garrison to defend him against allegations of financial misconduct.
