Why This Topic Landed in Japan

Japanese fans cleaning up stadiums after World Cup matches has become a point of national pride, frequently cited as proof of Japanese "civility." A claim — pushed by a Korean YouTuber couple and a Korean-resident community newspaper — that this practice actually originated with Korean supporters at a 1985 Japan-Korea qualifier struck at the heart of that pride, triggering a strong rejection. At the same time, soccer fans were aware that veteran supporter leaders themselves had once credited Korean influence, so the reaction split between emotional dismissal and a sober "if you check the sources, it might be true" verification.

Key Reaction Themes

  • Mockery of the "origin" claim as self-absorbed — Many dismissed the psychology outright: "we're just doing what we learned as kids," "Korea always minds Japan, never the reverse."
  • A surprised reckoning that it might be real — When the testimony of former supporter-group leaders was surfaced, some users admitted, "so it was common knowledge among veterans?"
  • Soccer comes second — Cynics jabbed that Korea should "worry about the match it lost" before fussing over origins.

  • "I have a Korean gaming friend who told me: some idiots seriously start saying stuff like this and broadcast it overseas, so the rest of us get treated like idiots too — it's unbearable."
  • "Stop looking over here — so self-absorbed."
  • "Korea is always minding Japan, but it's never the other way around."

Comments:

  • "Wha—?!!"
  • "For real? You mean... we copied it?"
  • "The reps of the major supporter groups all say it was Korean influence, so the answer's settled. Asahi Ueda (leader of the supporter group Ultras Nippon): 'We saw Koreans picking up trash, so Ultras Nippon started picking up trash too.' https://web.archive.org/web/20221125104056/https://asagei.biz/excerpt/51655 Koichi Yoshizawa (supporter group Crazy..."
  • "Wha—?! I thought Korea was just claiming the origin on its own, but it's common knowledge even among veteran Japanese supporters?"
  • "Yeah. Of course there were always a few who'd pick up trash since soccer began, but the direct roots of the current Japan team's cleanup are Ultras Nippon and Crazy Calls, and they say they started because of Korean influence."
  • "So it's seriously Korean in origin?"
  • "Yeah. Yoshizawa saw Koreans picking up trash at a Japan-Korea match and started doing it, and it spread from Urawa supporters across the whole J.League."
  • "Huh, didn't know that."
  • "Koreans really obsess over 'origins' and 'roots,' huh."
  • "But Koreans didn't keep picking up trash, and the ones actually doing it now are Japanese, right? That kind of says it all, doesn't it?"

Meme-ification and "you lost the match" jabs

The origin dispute was consumed as a meme, with sarcasm tying it to the team's loss.

Comments:

  • "A nation that lost the war is beneath us."
  • "Ordinary Japanese people aren't interested in Korea, lol."
  • "'The desire not to lose drives me to pick up trash!!' ...As if!!"
  • "The origin of trash-picking is Korea."
  • "Now they're even claiming the origin of trash-picking, lol."
  • "I figured they'd say something like 'the origin of trash-picking is Korea'... and they actually did, lol."
  • "It's because they fuss over stuff like this that they lost the actual soccer match."
  • "Isn't it because Japan's trash media keeps hyping 'archrival Korea!' and 'rival Korea!' every time that they got the wrong idea? Since when did Korea become a rival or archenemy?"
  • "Korea figured its qualification was secure, so it coasted in the South Africa match to avoid fatigue, after all."
