In what version of Emacs?  All released versions of Emacs support
only part of the BMP.  Specifically, these ranges of Unicode
codepoints are supported:

  0100..33ff
  e000..ffff

If katakana characters are not in these ranges, you cannot have them
in unicode.

The CVS version of Emacs can (I think) convert katakana to Unicode
when encoding and decoding text.  I also think you can have this with
released versions if you install ucs-tables (look on
gnu.emacs.sources).
