After the Blue Samurai's achievement of being the first Asian team to beat a South American side in a World Cup match on June 19, fans celebrated by... staying back at the Saransk stadium in Russian Federation and tidying up after themselves.
But instead of going wild in the stands and then going off to celebrate on the streets of Russian Federation, some supporters chose to stay behind and help clean up litter.
Japan-based football writer Scott McIntyre told the BBC that cleaning up after themselves is something that is drilled into these supporters from a young age back home.
Japan and Senegal supporters at the FIFA World Cup in Russian Federation have become a viral hit after they were filmed cleaning up the stadium after their respective matches.
According to a translation of the video, the Colombian man filming the Japanese fans can be heard praising the nation's culture and scolding his own people for not following their example. "An important aspect of Japanese society is making sure that everything is absolutely clean and that's the case in all sporting events", McIntyre explained. Though it might seem exceptional in other countries, taking responsibility for cleaning up is seen as standard in Japan. The team's prospects this year now look far more encouraging.

Social media, of course, had its say.
