Which Irenaean culture would be the most Oriental/Chinese/Japanese in aesthetics and feel?

None, really. The world is mostly based on Europe, Persia, and a bit of India. The farthest east is something like the Sultan of Paradise, but there's no China or Japan.

That said, you're welcome to add some interpretative flare to whatever culture you'd like, there just isn't a direct equivalent.

EDIT: [@Hygswitch] is also correct on the matter.
