Japan still uses Shift-JIS for practically everything, much to the chagrin of anyone else in the world looking to use their applications.
I visit some Japanese websites from time to time (not that I can read or anything .. just clicking on links) and don't remember having many problems with weird characters.
I'd be really surprised if there are still sites that don't use utf8.
