I can't really comment on how clean (or not) places in Japan are when compared to places in other countries... I've lived here exclusively for far too long. I don't even remember the state of cleanliness when I lived in the US.

But compared to places I have been in Japan - quite a few - Osaka takes the cake when it comes to griminess. Not saying that the city is a bad place, of course. I would live there over Tokyo if I had to choose between the two... But by my standards, it is a really grimy place.

Nagoya is just really clean, which I suppose doesn't really help my feelings about it either.
