I was in Korea for 2 weeks and I thought while the restrooms were more clean in some sense, it was probably mostly due to having more personnel cleaning it up - in Europe it seems cleaning personnel is too expensive, so often they only clean once a day or once every other day On the other hand I saw this in Korea, they have these toilets that are basically holes in the ground . so you are supposed to squat down - I guess in some ways this is more hygienic, but also it is kind of odd. Another thing I noticed was that they had open wastebins in the restrooms and you were supposed to dump the used toilet paper in them, into a pile with the used paper of other people - I found this disgusting. But apparently they have a problem there with pipes getting clogged with the toilet paper
