KIX arrivals get the same failure mode as Narita: a QR code in a corridor with no data.
Install on hotel/home Wi-Fi the night before. Turn the Japan line on after landing. Buy a physical SIM at the airport only if the phone refused the eSIM.
ICOCA/Suica tap still works with no data. Maps, IC top-up, and translation do not.
