I have followed this wiki guide: https://wiki.archlinux.org/title/Localization/Japanese#Japanese_Input, picking Fcitx5 and Mozc, but I still don’t have a functioning setup after spending 3 evenings on it.

I have the IME selector in the top bar where I can select Mozc and the Mozc menus display just fine.


(Gnome doesn’t let me screenshot this menu, for some reason)

  1. But as you can see, the IME name is replaced by a white rectangle, I guess it should be a Japanese character.
  2. When I try typing with Mozc activated, the popup does appear and the output text is written in Japanese characters, which means I have correctly installed the Japanese font, but the popup contains white rectangles instead of Japanese characters.

I think this means that Gnome doesn’t find the Japanese font, but I couldn’t find in the guide how to tell Gnome to use it.

Can anyone give me a hint?
