I just wanted to say that I have Japanese input working with both anthy and mocz.
My ~/.xpofile looks like this:

export QT_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"

And my ~/.config/plasma-localerc looks like this:

[Formats]
LANG=ja_JP.UTF-8

[Translations]
LANGUAGE=en_US

With only en_US.UTF-8 and ja_JP.UTF-8 uncommented in /etc/locale.gen (and generated)

I don't know if this has anything to do with this, but I thought I'd add it just in case.
I'd be happy to help if needed.

Thanks a lot photodiode.

I set as follows.

user $ cat ~/.xprofile
export QT_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"

user $ cat ~/.config/plasma-localerc

I am sorry that I do not know how to use "code tags".

When I create "~/.bashrc file" and "~/.xprofile file", I get an error message.

Is there a way to solve this problem?
I am in trouble because a lot of error messages came out.
Could you tell me the professor, please?
Thank you very much.

Sorry, it's hard to say what could be wrong (if anything)..

When exactly does the error appear?
Is it when you confirm a word, or just randomly?
Also I see that you have updates in the screenshots, is your system up to date?

Thanks a lot photodiode.

Thanks for your advice.
This problem is very difficult for me.
I'd like to close this thread.
Many thanks.

Before stopping to figure this issue, please post the contents of /etc/locale.conf

Contents of /etc/locale.conf are as follows.

user $ cat /etc/locale.conf
LC_ADDRESS=ja_JP.UTF-8
LC_IDENTIFICATION=ja_JP.UTF-8
LC_TIME=ja_JP.UTF-8
LC_PAPER=ja_JP.UTF-8
LANG=ja_JP.UTF-8
LC_MEASUREMENT=ja_JP.UTF-8
LC_MONETARY=ja_JP.UTF-8
LC_NAME=ja_JP.UTF-8
LC_NUMERIC=ja_JP.UTF-8
LC_TELEPHONE=ja_JP.UTF-8

@photodiode can you compare that locale.conf to what you have? Calamares, the installer, recently changed to this format so you might not have this.

    What exactly is that I have?
    I updated the system.

    Contents of ~/.config/plasma-localerc are as folloes.

      enpitu please add code tags, I've been doing it for you so far, but it really is simple to do. Either enclose code with 3 back ticks (```) or use the editor menu and click on "Code".
      And if you still don't understand, just "edit" one of your posts, you see how the code tags are added.

        Thanks a lot demm.

        I use "KaOSx KDE" as the very beautiful "Linux OS" of the English version.
