by the way, You can add a line to your .emacs.
(set-fontset-font "fontset-default" 'han "FONTFAMILY FONTSIZE" )
replace "FONTFAMILY" and FONTSIZE according to your environment.
And FONTSIZE can be ignored if you had no need to specify a size for this font.

Would you please provide some example characters and such a font to
help us make it better?

Here's an example from my (Debian) system; the font I chose in Emacs
is "Droid Sans Mono"; the "x11 size" is 13 [which isn't exactly the
size chosen in the UI; fontconfig sizes and X font sizes seem to be
only loosely related... :( ]

I set the font to "Droid Sans Mono", and the Japanese font Emacs
automatically chose was "きろ字".  I don't know _why_ Emacs chose that
font, as other apps don't seem to -- If I select Droid S M in GTK
apps, for instance, they use something much better looking, probably
"Droid Fallback" (which is a matching font for Droid S M).

I've attached an image file showing what this looks like on my
computer.

The things I notice:

  (1) The font chosen by Emacs for Japanese might be a bit odd, and
  doesn't seem to match what other apps choose.

  (2) The "きろ字" font is already pretty widely spaced, maybe near
  the limit of readability IMO.

  (3) It looks like forcing CJK alignment to 2*ASCII will increase the
  width of characters in this font by about 30%.  Given the already
  very wide spacing, I think the result might look funny.

  [ (4) If I grow or shrink the font-size, the ASCII and Japanese grow
  by different, and varying amounts (that is, there are obvious
  "jumps" in the size increases, and the jumps occur at different
  places for the ASCII font and the Japanese font); my guess is that
  this is probably due to rounding by the font renderer.  So there
  will be. ]

Now that I think about it, I'd say that the problem seems to lie more
with Emacs' choice of fonts for Japanese (both the funny automatic
choice, and the lack of good methods for users to tweak it).

Thanks,

-Miles
