Not Japan origin:

That's a little weird
I suspect it is not just for Japan. For example Allociné uses "Les Pennac(s): Un Air de Famille" as title.



That's just the old main titles, from the first episode, I doubt that the name was used for the whole series, probably just an error in IMDb.

For these last two, even if other countries were involved, these are mostly American movies (listed as such on Wikipedia for example).
In some cases there is no clear origin between two countries, but I don't think it is the case here.
Multiple-countries origin is clear for some titles, like Power Rangers Zeo mentioned above. For that one Wikipedia also mentions also US/JP as origin.
