Ummm, don't you guys know that Japanese Animation (Anime) first took inspiration from Disney cartoons? And from those roots, well we come to know anime as it is now.
Pretty ironic right? But I'm not sure it's affecting it as much as you guys think. It's just a different style for both, regardless what cartoon you're watching. There might be some sort of ressemblance sometimes, but still very distinct one from another.
