I know in the Japanese version of the PS4 by default that its:
- X: キャンセル / 戻る [Cancel / Back]
- O: 選択 / 確認 [Select / Confirm]
While in most consoles globally: the X button is used to select or confirm something while the O button is for cancel, basically the sequences are inverted. I know this because I’ve played games on a Japanese PS, even in GTA V (the imputs for either button have been adjusted on that version).
X & O are reversed in the rest of the world because they noticed pretty quickly that the ok/go/yes button should be in the most ergonomic place your thumb naturally rests on. By PS5, Japan joined in with the rest of us
