Sometimes the hustle and bustle of big city life in Tokyo makes you forget your manners. With most people commuting by train and working very long hours, sometimes there’s no time to do things at home. And sometimes, you’re just so tired and stressed that you don’t care that you are behaving badly.

As a result, back in 2008, the Tokyo Metro system launched a three-year-long campaign aimed at reminding subway passengers to mind their manners while riding the trains.

Some of these are hilarious.
