That was actually a Dutch/Japan co-production. There were also atleast 4 other country networks outside those two that participated in cofunding it. Pretty interesting one, too. Actualy Series Composition, Music, and general Character Designs is Dutch, but the Script Writing, Sound Design, Storyboarding, and everything else is Japanese. It was also one of Megumi Hayashibara's older works and one of the few roles that she did a younger main character.
Oddly enough, the only full version of the opening and ending song (despite being originally recorded in Dutch), is in Japanese. Either way, I honestly prefer the Japanese versions of the songs, partiually for the full set of instruments that were used, rather than the simplistic music design on the Dutch based versions.
Regardless of the language, whether it was Dutch or Japanese, I seriously enjoyed it. I was seriously shocked at a number of things that serious dulged into, going from dealing with death, growing up, dealing with bullies, and among other things. I really should finish watching it though.
Anyways, getting on subject, I believe W.I.T.C.H. is another series that's foreign, or rather co-produced. I believe it's french, unless I am mistaken. I know France is doing another series soon. Basquash, is apparently being done by the Oban - Star Racers crew and being co-produced with Satelight. Apparently Kawamori Shouji is involved.
