Selection bias. Those that work internationally and learnt English properly have a different attitude than those that stay, they usually spend enormous amount of effort learning the language because they don’t fit in or don’t want to. I’ve traveled around with Japanese and they definitely appreciate cleanliness and politeness more than any others. I’ve had multiple Japanese people cry saying how lucky they are to have been born in Japan when they have a short stay in pretty well off countries. This doesn’t mean that they can’t be dirty, I’ve seen bones for ramen cracked on the streets here. Just that they appreciate cleanliness a lot. I think red mold popping up everywhere all the time makes you more careful, at least I became more aware after moving here.
