After Japan’s “Samurai Blue” beat Tunisia 4-0 on Saturday, Japanese supporters stay behind to clean up Monterrey’s stadium. Multiple accounts describe fans collecting litter from the stands rather than leaving immediately after the match. The behaviour is reported to be a known practice in Japan called “gomi hiroi,” meaning the act of picking up trash, and is linked to an emphasis on personal responsibility for shared public spaces. One fan, Ken Okawa, is cited as saying he was happy to take part in the clean-up. Reports frame the clean-up as part of the match-day response to a successful result, with supporters treating the stadium environment as something that should be restored for others after the game. The accounts also note the context of Japan’s victory, which comes during the 1,000th match in World Cup history. Overall, the coverage portrays the clean-up as organised, voluntary conduct by fans following the match in Monterrey.
