Well, Unicode's Han unification process kind of screwed Japan, so that's somewhat understandable. It makes it hard to use Unicode for historical documents with older variants, documents using more than one CJK language (like talking about Chinese in Japanese), and worst of all, a lot of theoretically-compatible CJK fonts look wrong because they chose Chinese glyphs. There's many ways Unicode is an improvement over what came before, but they screwed up with Han unification.
