Payments1
Apple Pay
Use instead: Suica (Apple Wallet) · PayPay QR (via Alipay+)
Apple Pay + Suica cover trains, konbini and chains, but many small restaurants and shops are cash- or PayPay-only — carry yen.
Messaging1
Use instead: LINE
WhatsApp works but is rarely used. LINE is the standard messaging app in Japan.
Maps & Navigation1
Google Maps
No direct substitute
Google Maps works excellently in Japan, with detailed train and subway routing.
Ride-hailing1
Uber
Use instead: GO / DiDi
Uber exists but mostly books regular taxis and is limited. The GO taxi app is more widely used.
Internet Access1
US carrier roaming
Use instead: eSIM (Airalo / Ubigi) or pocket Wi-Fi rental
Roaming works but is pricey; a travel eSIM set up before you fly is the easy win, or rent a pocket Wi-Fi at the airport.
Social Media Access1
Instagram / Facebook / X
No direct substitute
All major social apps work normally; X (Twitter) and LINE are especially popular in Japan.
