Referring to yourself in third person is pretty normal, but it isn`t what the original poster was asking about...

Ponyo brought up that same sort of question with Japanese viewers. Why does he call his parents by name? Is it following after some country where it`s normal? Are they not his real parents? etc etc. Supposedly it was an artistic move to represent them all as distinct people, and not let anyone fall into the faceless roles of "mother" and "father".

In other words, it isn`t normal in Japan and doesn`t represent real life.

The closest to using ちち/はは for your own parents I have seen is jokingly calling them 父親様/母親様 like my husband and his siblings do to their parents. The key is that it`s jokingly and not what you`d REALLY call them.
