Whenever I'm in Japan I marvel at the efficient, clean, quiet, and comfortable trains. The passengers are polite, and the train employees bow when moving from one car to another.
Right now there is some kind of international sports-ball tournament going on in Japan, and a Japanese woman shot a video of some obnoxious French soccer fans acting like jackasses on the train. They are lying in the aisle, carrying each other, yelling, bumping into other people, and putting their dirty shoes on the seats. This Logan Paul-like idiocy would be looked down upon even on a European train, but in Japan it's unthinkable.
In this video That Japanese Man Yuta shows the video and the Japanese reactions to it on social media.
