It seems that fonts-ipaexfont-{mincho|gothic} packages
contain a fontconfig setting file that raise own priority.

I've tried some Japanese fonts with `-dgs-load-fonts' option.

"IPAMincho" in ipam.ttf:
    fine.

"IPAPMincho" in ipamp.ttf:
    fine.

"IPAexMincho" in ipaexm.ttf:
    compilation failed due to ghostscript error.

"MS Mincho" in msmincho.ttc:
    compilation successful
    but all Japanese characters are shown as TOFU.

"MS PMincho" in msmincho.ttc:
    compilation successful but all Japanese characters are vanished.

"Noto Sans CJK JP" in NotoSansCJK.ttc:
    compilation failed due to ghostscript error.

"Source Han Sans" in SourceHanSans-Regular.otf:
    fine.

So most Japanese fonts can not be used with `-dgs-load-fonts' option.

In addition, all fonts of the above without `-dgs-load-fonts' option are fine.
I suggest removing `-dgs-load-fonts' option from lilypond-book.
I think that `--bigpdfs' option is more suitable than `-dgs-load-fonts'.
