[Groff] Japanease characters with groff

[Lenga, Yair [CIB-FI]]

Hi,
 
I have several reports (based on groff), which need to be translated to
Japanese. The translation include replacing table heading, and
background text. As much as I can tell, all the Japanese text will go
through roff (and not TBL). I found several references to jgroff - but
this seems to be abandoned project.
 
Anyone has experience with this projects ?
 
Thanks
