Surprisingly, it works for me (I haven't been able to type Japanese for 
months). I tried in icecat and console.

Hmm, I don't have GTK_IM_MODULE set in my ~/.profile (don't remember why 
I removed it...). I have these:

# GUIX RELATED VARIABLES TO WORK AROUND BUG #35610
# https://issues.guix.gnu.org/issue/35610
# 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"
# These are needed only to work on Qt apps like TeXmacs.
export XMODIFIERS="@im=ibus"  # Set X input method server (xim) to ibus.
export QT_IM_MODULE="ibus"    # Set Qt input method module to ibus.

I install ibus engines in my profile. I tried installing them in the 
system profile, and that never worked for me. But I haven't tried recently.

For what it's worth, I was suggested to run the engine directly when I 
was having trouble with ibus-stt 
(https://github.com/PhilippeRo/IBus-Speech-To-Text/discussions/7). So maybe

/gnu/store/1s0p8fk1bgp0v2gv5dgjgpq1v4p3nwji-ibus-libpinyin-1.15.2/libexec/ibus-engine-libpinyin 
--gapplication-replace -g

That helped me fix some ibus-stt errors. (And actually, I see an error 
when running the ibus-anthy engine, which might be why I can't even find 
the engine listed in input options).

Good luck,
