[ASK] How to type Japanese Character in Linux Apps??

Hello everyone, is there any ways to type japanese character in Linux Application like OpenOffice, Kwrite, terminal, and other application??
I’m using OpenSuse 11.3 and I think I’ve install Japanese character support for my OpenSuse. But, I didn’t know how type a japanese character in Linux Application. When using Windows, I only need to change the language bar to japanese to type in japanese character, but I didn’t know how to do this in Linux.
Thanks for the Attention and sorry for my poor English.

System settings>Regional and language>Keyboard layout and select Japan

It’s not working.

Finally it’s solved. I used SCIM to change my input type. Now I can type Japanese character in Linux Application rotfl!
