Can I get a SIM card in Japan as a tourist?

Yes, you’ll be able to get a SIM card and use your cell phone in Japan, but there are some requirements as a tourist. To buy and register your Japanese SIM card, you’ll need:

A valid passport and a copy (for identification purposes)
Working payment method (credit/debit card or local currency in cash)
An unlocked phone to accept foreign carriers
Proof of accommodation/stay (some carriers require this)

The entire SIM card registration process takes anywhere between 15 minutes and an hour, longer especially during peak season. If you’d enjoy connecting in Japan without lengthy registration times, consider an eSIM over a physical SIM card.
