Former Nissan Motor Co. Chairman Carlos Ghosn's incognito emergence Wednesday from a Tokyo jail launched a barrage of speculation and amusement from the media and the public over his motive for donning a cap, surgical mask and construction worker outfit upon his release.

On Friday, the confused Japanese public got an answer.

Takashi Takano, one of Ghosn's attorneys, confessed in a blog post that it was his idea to protect Ghosn's well-being, but it failed. Ghosn, who turns 65 on Saturday, was released on bail after 108 days of detention.
