Japan fans left the stands spotless after their World Cup opener against the Netherlands in Texas on Sunday, saying it was "Japanese culture" to tidy up after themselves.Japan are appearing at their eighth straight World Cup and their fans' cleanliness has become their international calling card.
The kids do all the daily cleaning, they still don’t have janitors. The school still has maintenance workers. I’m certain the large machinery would be handled by them and would be considered part of maintenance and not cleaning.
I think you are right in that the schools are smaller, every square inch of urban area feels like 15 minute city material. So everything people need in daily life is within reach, small but numerous. I’m no expert though, just a tourist who visits his Japanese friends and asks lots of questions 😅
