One time last year I had to stay overnight in Japan to reach a connecting flight. The airport allowed people to sleep on the benches (very comfortable with no arm rests), and a police man stands there all night and watches over everyone to keep them and their belongings safe.
To top it all off, there is a sign addressed to people sleeping there that at 3 AM the airport personnel need to polish the floors and they apologize for the noise!
Similar experience. I was in a Ryokan in Kyoto where some workers were about to repair some fittings in the street and make some noise. We were given a leaflet in English apologising for the noise made and the next day when we got out the supervisor was ready with a candy and a small toy for our daughter.
