Please try the following:

1) Make sure you've installed ibus, ibus-anthy, and a font package that
gives you appropriate fonts for Japanese.  For example:

  guix package -i ibus ibus-anthy font-adobe-source-han-sans

2) Make sure you've set the following environment variables in a place
where they will be made available to your desktop environment (in Guix
System, it is sufficient to put this in your ~/.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"

2) Remove the ibus cache:

  rm -rf ~/.cache/ibus

3) Log out and back in.

I was able to reproduce your issue in a Guix VM, and I was able to
resolve it by taking those steps.  Please let me know if this fixes the
issue for you, as well.
