Japanese football supporters continue a long-running tradition at the FIFA World Cup of cleaning up their own trash after games. Multiple outlets report that fans leave stadium sections “spotless” by collecting rubbish and disposing of it before they depart, framing the practice as part of “Japanese culture.” The coverage highlights examples from Japan’s matches in the United States, including the team’s World Cup opener against the Netherlands in Texas, where supporters were seen tidying the stands and packing waste into bags. Other reporting notes the tradition has been ongoing since 1998 and has become a recurring feature at international tournaments, with Japan fans’ cleanliness earning them a global reputation. Euronews also describes fans cleaning after Japan’s 4-0 win over Tunisia, reinforcing that the behavior persists across different matches. Some accounts include comments from Japan’s coach, Hajime Moriyasu, who expresses pride in the fans’ reputation for tidiness while adding a caveat that it should not eliminate the work of stadium cleaners. Overall, the reporting emphasizes the fans’ effort to respect venues and leave them cleaner than they found them.
