I have not been to Japan, but I have read several fairly detailed accounts coming from multiple travel bloggers.

One thing they all pointed out is that Japan is full of what by our standards would be considered semi-antique technology like trolleys from the 1950s and computers and fax machines from the 1990s, that are all still being used, and maintained in really good condition.

Living in Tokyo, do you notice this as well? I assume this sort of commitment to maintenance / "orderliness" must be cultural?

What do the really bad parts of Tokyo look like?
