Yeah, Japan was actually surprised when American game devs started using X for confirm. They never even anticipated that it would happen, because the X/O symbolism is so heavily engrained in their society that it was glaringly obvious to them that O was confirm. Their original intent was always to use the Nintendo layout for confirm/cancel, but then western devs misunderstood the buttons and swapped them.

To them, an O is like a checkmark or thumbs up emoji. Imagine if an American console maker developed a console with a thumbs up button, and Asian devs started using the thumbs up button as Cancel. You’d probably be pretty fucking confused too.
