*THIS PROCEDURE IS NOT STRICTLY NECESSARY ANYMORE, AS MOZC IS NOW PACKAGED IN UBUNTU BY DEFAULT. BUT USING THE REPOSITORIES PROVIDED HERE MAY STILL GIVE YOU THE UPDATED VERSIONS OF MOZC*
Google Japan recently announced on its blog that the Japanese Input Method, which has been in development since last December, is officially out of beta. There is actually an open-source version of this input method called Mozc, and I thought I would share with the community the procedure involved in setting it up since I didn't see any posts related to it.
The installation is essentially the same as ibus-anthy, but you first need to add two PPAs in order to retrieve the necessary packages.
The simplest method would be to add the repositories:
The first PPA (Launchpad Link) gives you Mozc packages while the second (Launchpad Link) gives you the updated packages for the Japanese environment. What you will then need to install are:
Once you restart, you should then see in the applet menu the keyboard icon. Under Preferences > Input Method, you can add Japanese > Mozc to enable the Mozc input method.
ibus ibus-mozc ibus-gtk
What's new and useful with Mozc is the auto-complete feature as well as inclusion of more 'web' or 'hip' languages that are not found in the previous input methods. I think this is definitely a great addition to the Japanese environment in Ubuntu.
