Comment 14 for bug 1958492

The "default" choice is an upstream one.

https://github.com/google/mozc/blob/master/src/unix/ibus/gen_mozc_xml.py#L227

The packaging for Debian/Ubuntu happens at Debian, and Ubuntu builds the thing using the same source as Debian.

So if you want to suggest a change, you should probably file an upstream issue:

https://github.com/google/mozc/issues

Or possibly a Debian bug:

https://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=ibus-mozc

But before you do, please understand that there is no perfect default configuration which is right for all users. As regards Ubuntu the current configuration works fine in some typical cases:

* If you do a Japanese install of Ubuntu, the jp layout is added together with Japanese (Mozc). My impression is that Japanese users often use the jp layout for typing English.

* If you do an English install of Ubuntu (and don't have a Japanese keyboard), you probably want the layout you are used to for inputting Japanese.

In the latest ibus-mozc version, you should not edit mozc.xml to change it, but there is a user specific configuration file:

$ cat ~/.config/mozc/ibus_config.textproto
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "default"
}

So.. If you bring your suggestion to upstream or Debian, please post the URL here for tracking purposes. The change you suggest is of such a nature that we won't do it in Ubuntu only.
