+fonts should be used for the standard Japanese (logical) fonts of pLaTeX and
+upLaTeX.  Font setup is realized by changing the font mapping of dvipdfmx, and
+thus users can use any (monospaced) physical fonts they like, once they
+properly install this package, without creating helper files for each new
+font.  This package also supports setup for the fonts used in the
+@code{japanese-otf} package.")
