While there's no doubt about the fact that we have a real fear of getting on the wrong train, and while we do agree that this guy's experience was a true vacation fail - we can't help but think that, actually, he's the one who is wrong! Yes, he is on a bullet train, but we have a feeling that the bullet train is probably going in the exact direction it should be going.
If anything, this guy is heading in the wrong direction! but these types of things are easily done, especially when you're in a new country and you don't speak the language.
