I have installed Japanese support for my wife but can't figure out how she can write in Japanese.

Windows has IME an input method editor that allows her to input Japanese characters.

HOW DO WE DO IT IN LINUX?????????????????????

Please I am very much in need of help here.

Thank you for the link, (DOMO)
I have both the canna server and freewnn starting at boot, also I have located kinput2.
I will try your editing solution.
Do you have any tips for using kinput2?

Edited files per your example, but cannot start kinput2 or type in Japanese.
Did I miss something?

Woops!
After I rebooted the machine the desktop was in Japanese!
I don't want that!
I want to simply input in Japanese.
Now when I opened OpenOffice and used [ctrl] + [space] I got a strange little symbol underneath cursor but I couldn't read it it was just vertical bars.
Do I need additional language packs for OO to see these things correctly?
Note:
I did install Japanese support for the system when I initially installed the OS.

Just put:

export LC_CTYPE=ja_JP

in the end of /etc/profile should be okay. But I don't know why you said that the whole things turn Japanese. Because LC_CTYPE=ja_JP will change the font coding, not the LOCALE!

For oo, you'll need to install font package. Use "ooadmin" or "spadmin" in latest open office. But the box will be empty. I usually type japanese in gedit.

Have you checked that kinput2 was started when you boot your computer? I mean in redhat-config-services.

By the way, it is not ctrl + space, it shift + space. The control + space is for iiimf (i think that's the name), new input method that comes with Fedora Core 2.

redhat-config-services?
Which one? I have alot of them?
When I said it changed the whole desktop to Japanese, I wasn't lying it did!
I only changed what you advised to change.

I can't find a simple Language pack on OO's site for japanese. I found some [.sh] file but I don't know what to do with it. (I downloaded it) but now what?

You open redhat-config-services as root from teminal window. Then, check kinput2 service.

You said that you changed the whole desktop to Japanese? What window manager do you use? And do you login in gui (runlevel 5)? Change the default language to American English. Because for the whole desktop to change to japanese, the LOCALE/LANG should be japanese. Try reverting everything back to normal (english environment), then try again.

And did the shift + space work? If it didn't work then there is no point changing anything.

As for OO I'll need to be at my Linux box as I'm using windows in library.

As for this part in my post:

Just export LC_CTYPE=ja_JP will be enough.

I am using the KDE desktop.

kinput2 is not listed as a service.

I have found two kinput2 files on my system though.

1.) usr/X11R6/bin/ size: 243,308
2.) usr/X11R6/lib/X11/app-defaults/ size: 4,087
