KIX is not Narita. Same failure mode: a QR in a corridor with no data.

Install on hotel 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 can work with no data. Maps, IC top-up, and translation do not.
