After Japan's 2014 World Cup defeat to Ivory Coast, fans famously cleaned their section of Arena Pernambuco in Brazil. While this kind of clean-up isn't an unusual phenomenon in Japan, social media exploded with praise for the tidy Samurai Blue supporters.

Communal cleaning continues into adulthood, and it encourages everyone to be responsible for their surroundings, wherever they may be. Check out the video above for some more examples!
