I just upgraded from Ubuntu 16.04 to 18.04 because of the Japanese (Mozc) Keyboard Layout problem and it persists in 18.04. Here is the problem described:
Below the answer is a comment that says I should install fcitx to get the "Configure Current Input Method" option. For that person it seems to have worked. But not for me.
In "Language Support" (Settings > Region & Language > Manage Installed Languages), I see under "Keyboard input method system" the following options: fcitx, IBus, XIM, none. Whichever option I choose I don't get the "Configure Current Input Method" option. And therefore I can't set the keyboard layout for Japanese (Mozc).
What am I doing wrong? I need to write Japanese and German, but writing Japanese and having a German keyboard layout pushed on me is really inconvenient.
My mozc.xml looks like this:
<component>
<version>2.20.2673.102+dfsg-2</version>
<name>com.google.IBus.Mozc</name>
<license>New BSD</license>

<setup>/usr/lib/mozc/mozc_tool --mode=config_dialog</setup>
<layout>default</layout>
<name>mozc-jp</name>
<longname>Mozc</longname>
</engine>
How should it look like at the end? Do the first two lines mean, I should make a backup copy? What do the @@ lines mean? And remove default and add jp? I'm trying to edit the file with gedit. Thank you very much for your help?
