Documents and/or e-mails in Japanese
 

I'm looking for a good/easy solution for using Japanese with GNU/Linux.

My wife speaks Japanese, so last year, I installed Emacs with Japanese support (using the emacs Mule package) for her and she could enter Japanese in Romaji and then by pressing backspace she could select kanjis and kanas. :)

I suppose the support for Japanese is easier now, so I'd like to know the opinion of users before trying again. :D

For instance:
- Which software are you using for making docs in Japanese?
- For e-mail in Japanese, KMail, Mozilla? something else?
- Which desktop with Japanese support? KDE? (last time I tried with KDE3 I was disappointed, maybe it's better now) Gnome? How did you configure Japanese with it? Are you happy with it?

Thanks in advance,
Sylvain.
