From here [0], 94.1% of .jp websites use UTF-8 and 6.5% use Shift-JIS. You can find a list of popular sites still using Shift-JIS here [1].

If you change your PC or your phone locale to Japanese and access mostly Japanese website, the font display on most major OS works well. It's probably fair to assume that's a very common setup for Japanese users, and probably for Chinese and Korean users as well.

I think the CJK "problem" is more apparent for international users who don't have the locale setup or dealing with multiple languages plain text at the same time.

Your own link shows that both Shift-JIS and EUC-JP are on an upward trend, which isn't what we'd expect if Unicode was succeeding. I can't see it listing examples of .jp sites using UTF-8; would be interesting to see how many of them are relying on text-as-images.

Yeah what lmm says is not what happend/thought in Japan. Japanese still uses Shift_JIS because they love (/s) legacy software. Using Shift_JIS isn't a practical solution.
