Let us call a spade a spade shall we? Asians have a considerable and measurable white bias when it comes to aesthetics.

Couple the skin-whitening phenomenon with the double-eyelid surgery explosion with the open-air admission of the Asians' who elect to do these procedures that the so-called "Hellenic" features are more desirable than their own - and you have more than circumstantial evidence for the proposition "The Japanese draw themselves as white."
...And that isn't even mentioning the fact that the characters they draw, by any reasonable appraisal look about as white as Christmas in Nebraska.
If the truth offends your sensibilities, then it is your sensibilities that need adjusting.
