Since 1974, Tokyo's Metro has created cute, quirky posters for their subway system to remind passengers of proper etiquette. Each fiscal year they roll out a new set of characters as the ambassadors of good manners, and for 2014 they've just revealed a new mascot (he's the lion in the center poster).
New posters appear monthly on the trains, often with themes coordinated to the holidays. The art adds a cheerful vibe to the subway cars, but they're also slyly effective, providing an entertaining way to encourage polite behavior without hitting passengers over the head with a boring list of rules and regulations. The 2014 series, named Miteru-chan will feature more personified animals, hopefully doing more adorable things like diving for pieces of cake. Check out some recent posters below and here.
