As people who like Japan a bit too much tend to be towards the nerd side of the spectrum of life, I thought it best to include a guide for the most popular linux distros out there, those based on Ubuntu
Guide for Japanese input on Linuxmint (Ubuntu based OS)
Tested and working fine on linuxmint 9 Isadora, so should work fine for Ubuntu 10 Lucid Lynx
in language support- Install/Remove languages
- Tick Japanese and ensure all components are marked, at the least Input Methods & extra fonts.
back on language support main tab- use package manager and search for and install anthy and all reqd dependancies (or sudo apt-get install anthy)
find ibus prefrences GUI in your main prefrences menu- select an input method \/
- Japanese > Anthy
- (may need to press add)
- in the first tab it is useful to select show icon in system tray and also set your shortcuts for enable/disable
- default is ctl + space to switch from Japanese back to Default
- hit close, restart and enjoy
