What must I do to type in Japanese?
I wish to use fcitx-mozc as Wakisaka recommends, but when I add 'Keyboard - Japanese' via Preferences > Fcitx Configuration, I get only a qwerty layout with Roman letter output, no Japanese formed by typing a Japanese word like 'sore'.
When I uncheck 'Only Show Current Language' and search 'Moz', there is no Mozc option.
In 'Keyboard and Mouse' via Start search > Keyboard Layout, I have "Keyboard model: Dell Latitude laptop" because this laptop is a Dell Latitude D620. I have tried adding the Keyboard layout: Japanese there, too, with Super+Space to switch, but still no Japanese output. The 'kana' variant does let me type katakana from each key, but I need to be typing in qwerty or dvorak converting hiragana to kanji or katakana.
I wonder if I have found a hint: An 18.04 user was told to edit /usr/share/ibus/component/mozc.xml, but my folder lacks this file.
Edit: I have now installed fcitx-mozc.

Edit: I was able to get it working with this guide.
(This answer from three years ago appears to have the solution I wound up implementing as described in my answer below, though I think fcitx is already installed in Lubuntu 18.10.)
The solution appears to have been simply following this guide, though I skipped the ppa commands. I recall executing the following commands while working through that guide:
Particularly, after running
im-configas instructed, selectingfcitx, and then restarting, it is now working. I am not sure if theqt4-qtconfigbusiness is necessary, because I was not able to get it working until I didim-config+restart through clicking the start menu entry (though I don't know if the restart is necessary).
