it's certainly an option, the availability of regex would make it a 
quick fix, but it's not ideal =)

Not quite sure what you meant there, since I can't really tell the 
difference between the three commands you listed. The first and last 
seem identical? At any rate, I tried this for the Kozuka Mincho Pro 
fonts by specifying:

\newcommand{\cjkfont}{\setmainfont[BoldFont={* H}]{Kozuka Mincho Pro}}% 
bold is the 'heavy' variant

but this doesn't really do much. Without the accolades around the 
Japanse, the Japanese still breaks the section formatting (and doesn't 
show up bold for that matter).
