Japan supporters at Sunday’s World Cup match against the Netherlands clean up the stadium stands after a 2-2 draw, using blue bags associated with a fan-led “cleansing” tradition. Following Japan’s late equalizer—Daichi Kamada scores in the 88th minute to level the game—fans celebrate, waving empty blue bags in the stands. After the final whistle, the same supporters shift to cleanup, collecting litter from their section and preparing to leave the stadium. The reported cleanup continues as attendees use the bags to remove trash rather than leaving it in place. The behavior is described as an established tradition among Samurai Blue supporters during World Cup matches, carried out even when the match result is decided late. The match ends with Japan and the Netherlands tied at 2-2 in Group F, and supporters’ post-match cleanup is portrayed as a routine part of the match-day experience. Both celebrations and cleanup occur in the immediate aftermath of the late goal and the final result.
