The Custom of Communal Cleaning
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.
This spirit of cleaning is taught very early in schools, where students are responsible for cleaning their classrooms and other spaces (click here for more on how they do it). But the origins trace even further back, and were likely influenced by the teachings of Zen Buddhism, which stipulates that a clear space equals a clear mind.
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!
