Default FONT when I create new document in docs(lool)

Hi, I am Japanese.

When I create new document in zdocs, for examle in writer,

It looks like default settings(style-character-Font tab settings) is "Liberation Sans" in Western Test Font(Lang=English(USA) and,

"Droid Sans Fallback" in Asian Test Font(Lang=simplified chinese)

Every time I create new documents, it is tedious to set Western font="Noto Serif JP" and Asian font="Noto Serif JP" and LANG=JP every time.

Do you know how to change default settings?

Please teach me.

Regards.
