Have you seen the difference between an Asian and a European face?
It's really about what is before you, Japanese have a relatively flat face making for much simpler lighting and their fat deposits are distributed in a way that makes lighting much more simple.
Now compare that to the average Western Asian/European male face, even women while they have much softer features are still on a completely different scale of complexity with jutting cheekbones, pretty prominent eye sockets and so on and on so forth.
Ultimately the best way to solve this non issue would be to cover the face with hair and just focus on drawing tits.
