Thought the name seems familiar: Jake Adelstein got his 2009 memoir Tokyo Vice turned into a (fun to watch, apparently very dramatized, though that was already criticized for the memoirs) 2 season HBO series in 2022.
He got called out several times about his stories so I wouldn't be surprised if he's making stuff up again.
Good point, WP [0] has some details, looks like pretty credible call outs.
I did read about that when I watched the show, but proceeded to forget because I didn’t actually care that much ;)
