In a scene that has become all too familiar, Japan’s football supporters once again took to the stands after a World Cup match, not to cheer but to clean. Armed with bin liners, they swept through the stadium, gathering plastic cups and discarded food wrappers with practised efficiency. The images went viral, hailed as a testament to Japanese culture and discipline. But beneath the global applause, a quieter, more uncomfortable conversation is stirring among women in Japan. They are asking: why can’t this spirit of civic duty be applied at home?
The narrative is predictable: Japanese fans clean stadiums, the world praises their selflessness, and Britons pat themselves on the back for recognising a gold standard in sportsmanship. Yet for many Japanese women, this ritualised cleanliness in public spaces masks a deep, private neglect. The same men who meticulously sort their rubbish at a World Cup match often return home to households where they do not lift a finger. According to a 2019 survey by the Cabinet Office, Japanese men spend an average of just 41 minutes a day on unpaid domestic work, compared to 3 hours and 44 minutes for women. This disparity is among the widest in the developed world.
“It’s a performance,” says Yuki Tanaka, a 34-year-old Tokyo teacher. “They clean the stadium to show respect to the world, but they don’t show respect to us.” Her words echo a growing sentiment that the collective pride in these acts is a convenient distraction from the persistent gender inequality at home. The term “sekuhara” (sexual harassment) and “matahara” (maternity harassment) are well-known, but there is no word for the quiet exhaustion of being the sole cleaner of a household.
It is not that the cleaning itself is the problem. The problem is the selective application of virtue. When Japanese fans clean a stadium in Qatar, they are performing for an international audience. The act is visible, measurable, and easily commodified into social media currency. But when they return to their apartments in Tokyo or Osaka, the invisible labour of wiping countertops and scrubbing toilets remains disproportionately women’s work. This is not a uniquely Japanese phenomenon. The British press, which has been quick to laud Japanese sportsmanship, might also glance inward: UK Office for National Statistics data shows women still do 60% more unpaid housework than men. Yet the British gold standard of sportsmanship often stops at the stadium gates.
From a technologist’s perspective, this is a classic data bias problem. We celebrate what we can measure. The clean stadium is a data point: 50,000 fans, zero litter. The hours of unrecorded domestic labour are invisible, undervalued, and uncelebrated. In my work on digital sovereignty and AI ethics, I have seen how algorithms amplify existing inequalities by optimising for what is trackable. The same is true here. The clean stadium gets a hashtag. The clean home does not.
This is not to diminish the genuine goodwill behind the Japanese fans’ actions. It is a beautiful gesture, a quiet rebuke to the disposable culture that plagues global events. But as we marvel at the choreographed order of a post-match clean-up, we must also ask: who is cleaning up at home? And why is that labour not celebrated with equal fervour?
Perhaps the solution lies in technology. Smart home devices could track and redistribute household chores. A ”domestic labour ledger“ on a blockchain could make invisible work visible, allowing families to see who is contributing what. But technology alone cannot fix a cultural gap. The real shift must be in perception: treating the home as a shared stadium, where every member of the family is part of the team.
For now, the Japanese women who speak out are not critics of their country’s football fans. They are critics of a double standard that applauds a man for cleaning a stadium but does not expect him to clean a bathroom. “Do it at home too,” they say. It is a simple request, but one that might be harder than any World Cup win. After all, cleaning a stadium takes an hour. Changing a culture takes generations.
