OP has shown one, from a jomon, which is a blatant hybrid between Whites and azuns, as I explained
older yayoi skulls are a lot more asiatic (pic related: round orbits, tall nose, lower vault, incomplete brow ridges)
modern Nips are crossed between both, and that's how you easily recognize them from gooks, for instance

as to the cranial vault, a taller one raises the brain volume, which is correlated to intelligence, as long as you remain among close species
technically, the brain surface and interconnections are what matters, but the volume is a good enough approximation, again, as long as you remain among close enough species
