Japanese football fans are once again gaining attention at the World Cup for their post-match stadium cleanups. This practice dates back to the 1998 World Cup and has become a widely recognized tradition associated with Japanese supporters. Following matches, fans remain behind to collect litter and restore the stadium to its original condition. This display of respect for the venue and the host country has consistently garnered positive international attention. The tradition highlights a cultural emphasis on collective responsibility and leaving spaces better than they found them. It continues to be a defining characteristic of Japanese fan culture at international sporting events.
