Well, there are AFAIUI dual-width fonts with both western and asian 
glyphs which line up and are stylistically consistent, such as IPAGothic 
(debian package otf-ipafont-gothic).  I suspect they may cover a lot of 
people's needs. Try

fc-list :spacing=dual

to see if you have any currently installed.

One rather brute-force way (with the distinct advantage that it works) 
to force use of _only_ particular well-matched fonts in emacs is to 
limit the fonts visible to emacs at all, at the libfontconfig level.

You can do that using an alternate fontconfig configuration file that 
points at a directory with only the particular fonts you want used in 
it.  The libfontconfig override mechanism is documented to be via an 
environment variable FC_CONFIG_FILE, but the actual environment variable 
is apparently FONTCONFIG_FILE.  (If you're doing that, you also need to 
force use of _only_ the xft font rendering, not both xft and core x, 
with "Emacs.FontBackend: xft" in your x resource db (~/.Xdefaults))
