Lol, technically - and this is a little picky. Moomins, while being a swedish creation, the animation was made first in Japan. Yeah~ So if you ever watched that...
Of course, you've got shiz like Pokemon and Digimon. Everyone watched them. But like, the first one, when i decided that i'd try it out, was Fushigi Yuugi. Nuriko~~~~~ Oh Nuriko. =[
