Off-topic Anon, here we go.

It's known as Mukokuseki, and some of it came from early artists being influenced heavily by the likes of Walt Disney and some of it is to make their characters look more distinct/"interesting".

Japan is a fairly homogeneous nation, as a result of long-term isolation and strict immigration policies.

(Brown is still the Dominant gene for eye color in humans, though.)
