No luck there.  Tested this time with Publican-2.2, using ja-JP 
XML files, if that matters.

All fonts are TrueType (CID) embedded subset unless otherwise
specified.

LiberationMono-Italic
IPAGothic
IPAPGothic
Times-Roman                 (Type 1, not embedded)
LiberationSans-Italic
LiberationSans-BoldItalic
LiberationMono-BoldItalic
Symbol                      (Type 1, not embedded)

Note that roman fonts (like LibSans) work fine for italic/bold-italic, 
it's only if there's a tag which renders to italic around something 
getting set at least partially in IPAPGothic or something similar.

I believe the primary body font is IPAPGothic, looking at pdf.xsl.
