Smoking is bad. Don't do it! But that's not why the new Jojo's Bizarre Adventure anime is being censored. It's because this is underage smoking.
In the most recent Japanese broadcast of the Jojo's Bizarre Adventure anime, the face of Jotaro Kujo is covered in blackness to censor the cigarette in his mouth. This is even more baffling when you realize the smoke isn't censored, drawing even more attention to the cigarette.
