People probably automatically assume that this name is pronounced "ah-MAY-ah". Well, judging by the spelling (and my prior knowledge of Japanese), I think this name is most likely pronounced "ah-MYE-ah". Thanks!
I've only heard it pronounced A-Mye-Ah. When I was working as a waitress, two of the guys wives were pregnant and due at the same time. Both of them, without even knowing it, named their daughters Amaya. I'd never heard the name up to that point and then two acquaintances named their daughters this at the same time. It was weird.
