That question is actually one I have been investigating, and so far, all I have is that two voice actresses from the series declared it as a French series, then the Netherlands debuted it prior to Germany.

With my biased opinion, my origin guesses are Germany (because that is where the old series originated), or Belgium, because my research showed production there, and because a Belgian girl sang the prominent intro (weak support, I know.)
