Supporters of the Japan national football team have garnered attention for their cleanup activities after matches during the FIFA World Cup in North and Central America. Notably, following the match where Moriyasu's Japan drew 2-2 with the Netherlands, some supporters voluntarily picked up trash in the stands. This action was highlighted by overseas media such as ESPN, and FIFA shared videos of the cleanup on their official X account. While the cleanup efforts of the Japanese supporters are praised for garnering international recognition, some Chinese media have expressed skepticism. They reported that the actions of the Japanese fans have been criticized as 'performative acts.' On social media, there are opinions suggesting that the cleanup is not driven by genuine goodwill but rather as a means to attract international attention. The commendable actions of Japan's supporters have drawn global interest, but opinions on their intentions remain divided.
