I found the discussion. The topic is "Typing on GuixSD in languages other than English" (https://lists.gnu.org/archive/html/help-guix/2016-04/msg00006.html). I participated, I'm Luis Felipe :)

So, yeah, that didn't work for me. I added the exports to my "~/.bash_profile", rebooted, and still no "Japanese (Anthy)" listed anywhere.

Looking at ison's exports, I thought, "I 've seen this before", and yes, I found in my old notes about IBus that when you started IBus Preferences for the first time you were ask whether you wanted to start the ibus daemon, and on Yes, you were asked to export the following too:

    export GTK_IM_MODULE=ibus
    export XMODIFIERS=@im=ibus
    export QT_IM_MODULE=ibus

(For people reading this in the list archives, the second line is "export XMODIFIERS=ATim=ibus", where "AT" is the "at sign". The archives interpret it as an email address and won't display the line correctly).

The difference with ison's is that these exports use "ibus", not "xim". Ricardo mentions the three lines above in the previous discussion on the list too (https://lists.gnu.org/archive/html/help-guix/2016-04/msg00016.html). So I also tried this in my "~/.bash_profile":

    export GUIX_GTK2_IM_MODULE_FILE="$HOME/.guix-profile/lib/gtk-2.0/2.10.0/immodules-gtk2.cache" 
    export GUIX_GTK3_IM_MODULE_FILE="$HOME/.guix-profile/lib/gtk-3.0/3.0.0/immodules-gtk3.cache" 
    export IBUS_COMPONENT_PATH="$HOME/.guix-profile/share/ibus/component"
    export GTK_IM_MODULE=ibus
    export XMODIFIERS=@im=ibus
    export QT_IM_MODULE=ibus

And then rebooted. But nothing changed. I still can't find "Japanese (Anthy)" anywhere.

Working around this issue seems difficult, so I'll use romaji for now.

Thanks ison, Chris, and Florian for the help :)
