What I don't know how to do, or if it's even possible, is typesetting a book / story / poem in such layout. I am basically looking for two approaches:
- LibreOffice Writer way. Here I know how to write Japanese, I even have some nice free, but sadly not libre fonts, but I don't know how to set vertical text layout. Anyone knows if it is possible and if so, how to do it?
- TeX way. I've been using plain TeX for ages but I still neither know how to typeset Japanese nor how to use vertical text layout there. Any pointers for both of these are welcome.
EDIT: ad 1. Looks like I have been blind. Thanks to Vorbote for useful links. It's as easy as doing Format->Page->Page->Text Direction = Right-to-left (vertical).
