A tweet posted at 12:51 p.m. on Wednesday under the name of former Nissan Motor Co. Chairman Carlos Ghosn was initially met with great skepticism.

The profile photo was his headshot, featuring gray hair and a cherry blossom tree in the background. Journalists were abuzz speculating about the veracity of the account.

"I'm getting ready to tell the truth about what's happening," read the tweet, the account's first. "Press conference on Thursday, April 11."
