As a reminder, while in Europe, American and western PlayStation games in general, X button is used for confirmation, in Japan and Asia it’s the O button instead. On Nintendo consoles too, the A button used for confirm is where PlayStation controllers’ O button would be. This is a culture difference in how in Japan, X (Batsu) is false, while O (Maru) is correct. You can easily notice this for example when characters in anime and manga show their school test results. Meanwhile on Xbox controllers, the A button used for confirm is at the same place as the PlayStation X button, following the western pattern.
Sony Interactive Entertainment public relations explained this is a change happening in all the Asia region including Japan, to solve the discomfort where games use either the X or O button as confirm but the console’s System Menu uses the other button as confirmation.
The PS5 is changing the default control scheme in Japan to the X button to match the rest of the world after decades of the O button as the default. That's going to be a HUGE change in terms of memory.
