Hi,
I noticed that libass renders japanese 'top to bottom' text wrong:
This is what mplayer does:

This is Aegisub (which for some unknown reason renders 声 as the
completely wrong character even though it's ok in the script...):

Apparently, if a japanese fontname starts with @, the @ is stripped
and all characters of the font are prerotated by 90 degree.
This only happens for CJK characters though:

Here are two screenshots of the font dialog to illustrate that:
Font with @-Prefix (Note the sample area (サンプル)):

Same font without @-Prefix:

This is the fansubs I used for the screenshots and where I extracted the
script+fonts from:

I had a cursory glance at the code and I think it might be a bit
more involving to add rotation based on fontname (and so far I haven't
found the time to dig into the code a bit more), so I'm posting it
to the list now. :)
HTH,
