I wouldn't say Japanese refuse to support unicode. I'd say that legacy encodings like EUC-JP/JIS/SJIS are still used because it's hard/unfeasible to convert systems and data that were built for earlier encodings to anything newer. But it's not like they offer some particular technical advantage over Unicode - indeed they only reason they don't suffer from CJK issues is that they have no support for C or K. ;) But speaking as a front-end webdev guy, it's been a looong time since I came in contact with any encoding here besides utf-8.
