Carriers won't sell a contract until your residence card carries an address. Bridge the gap with data that works the moment you land.

学校
Universities start in April; most language schools admit in January, April, July and October.
Your school issues the COE, the visa goes in your passport at home, and the residence card is printed at the airport.
The JLPT runs in July and December. N5 basics before you land make week one much easier.
Open a Yucho post-bank account early; landlords and phone carriers keep asking for one.
知恵
Register at the ward office within 14 days of moving in; the residence-card address unlocks everything else.
Keep this eSIM until your card carries an address, then switch to a cheap local contract.
A commuter pass between home and campus roughly halves the metro bill.
The 28-hour work permission is a checkbox at immigration; tick it on arrival.

EU, UK, Swiss, Australian, Mexican and Brazilian passports enter visa-free as tourists: 90 days, stamped on arrival. Checked Sep 8, 2026; rules change, confirm with your embassy.
Fill in Visit Japan Web before you fly; one QR covers immigration and customs.
Your passport only needs to stay valid for the length of the stay.
Student visas work differently: the COE from your school comes first, then the visa at your embassy. The 90-day rules above are for tourist entries.

If an EID appears, your phone takes an eSIM.
No EID? Don't buy this. The airport counters at Narita, Haneda and Kansai sell physical SIMs.

Not at purchase. Each plan says at checkout whether its days begin when you install it or when it first connects in Japan.
About two minutes. We email a QR code; scan it before you fly and forget about it.
One-for-one replacement, and any unused plan is refunded.
It depends on the plan, and checkout shows it before you pay. Hotspot uses the same data.
