At least, if the desired font does not contain glyphs for the Japanese
characters.
Unfortunately, the missing characters are only reported as "warning", not
as an "error". Therefore, LyX will not prominently report this. (You can
see the warnings when opening Document>LaTeX log.) BTW: The development
version of LyX has improved reporting of missing characters (a popup window).

The most simple method would be to use a font that has both, Latin and
Japanese glyphs in all the desired variants. (But this is hard to find...)

How can we get this:

"fontspec" is the font selecting package. It is automatically used by LyX if
you check the "use non-TeX fonts" box.

"auto".

So fontspec is loaded.

The problem is, that polyglossia does not support Japanese! Therefore, LyX
selects babel instead of polyglossia as language package as soon as a part
of the document is in Japanese language.
What are the options then:
* set the sans-serif or teletype(monospace) font to the Japanese font and
change the font family for Japanese text parts
(works only, if you have a "spare" font family).
* use a "dummy" language that is supported by polyglossia.
In the LaTeX preamble write, e.g.
\newfontfamily\telugufont{MS PMincho}
and in the document mark the Japanese text parts as beeing in the
language "telugu".
Fails, if you must rely on "babel strings (abstractname etc.) in
Japanese or other language features.
* Look up the font-changing command in the "fontspec" package documentation
(this time really in fontspec, not polyglossia) and use this in an ERT
(raw LaTeX) box. Don't forget to switch back to the standard font (again
in ERT).
(Cumbersome but safe.)
* Mark the Japanese text parts as Japanese (LyX will use babel), and
add the font-switching commands to "extrasjapanese". (If you want to go
this route, I'll try to find out the "magic" commands for the preamble.)
A hint for experimenting: The source panel (View>Source) can show what LyX
will print to the LaTeX file. With "whole document" instead of "current
paragraph", you can also see the generated preamble and find out which
languaga package is used, which font package is used etc (and hence, which
of the commands suggested in the LaTeX documentation you do not need to
print in the "LaTeX preamble".
Hope this helps
