Arriving in Japan as a Student: A Pre-Departure & First-Week Setup Guide
Updated: 2026-08-22
Quick answer
Hi, I'm Miya, and if you're heading to Japan for an April or September intake, take a breath — this is much more manageable than it looks online. Before you fly, you sort out documents and one simple way to stay connected for the first few days. Then, in your first week, you pick up your residence card, register at the ward office, and only after that do you set up a longer-term Japanese phone number for your bank, campus apps, and group chats.
The one thing I want you to remember is the order: the Japanese mobile contract comes after your residence card is in your hand, not before you leave home. Everything below is just that plan, laid out gently so nothing catches you by surprise.
Before you fly: paperwork to prepare
Start with the documents your school already asked for, because these are the ones that unlock everything else. Keep your passport, your Certificate of Eligibility (COE), your admission letter, and your school's contact details together — printed and as photos on your phone. Many students now receive their residence status electronically or get the residence card issued at the airport, so check the exact instructions your school sent for your arrival airport.
Bring more passport-style photos than you think you need; dorm forms, student ID, and city registration can each ask for one. Have some yen in cash for the first days, and note that opening things like a bank account or a phone contract will later ask for your residence card and often an address, which is exactly why we handle those in week one, not now.
Staying connected for the very first days
You don't need a Japanese phone number the moment you land, but you do need to reach maps, translation, your school, and family. The simplest bridge is a short-term travel eSIM you buy before departure and switch on at the airport, or the free wifi at the airport and your dorm for the first evening. That's enough to find your way and message people while your longer-term setup waits for the residence card.
Think of this first-days option as a temporary bridge, not your real plan. It gets you from the plane to your dorm and through orientation. Keep your home SIM in mind too, but be careful with roaming charges — a small prepaid travel data option is usually calmer for a week or two until your Japanese number is ready.
What the school sets up — and what it doesn't
Schools are wonderful at the academic side, and many walk you through the big official steps: they'll often help with ward office registration, national health insurance, opening a student bank account, and sometimes a group trip to set up basics. Orientation week usually includes campus wifi, your student ID, and the learning apps you'll log into every day.
What schools usually do not do is arrange your personal mobile phone contract for you. That part is yours, and it's genuinely fine — it just means nobody hands you a Japanese number automatically. So plan for it yourself: know that it comes after the residence card, and you'll avoid the classic surprise of realizing in week two that every app wants a number you don't have yet.
Your first week: residence card, ward office, then a number
Here's the order that keeps everything smooth. First, get your residence card — either at the airport or, if it's issued later, once your school confirms. Second, within the first days, go to your local ward or city office to register your address (jusho); this is where your residence card gets your address written on the back, and it often bundles with national health insurance and your My Number registration.
Only once that address is on your card does the rest fall into place. Now you can open or finish your bank account, and that's typically the moment a Japanese phone number becomes essential — the bank, campus systems, delivery apps, and your classmates' group chats all expect one. So the natural sequence is card, ward office, then number, and doing it in that order means each step has what the next one needs.
Getting your Japanese number and data, calmly
By the time your residence card has your address on it, you're ready for the part that unlocks daily student life — a Japanese number and steady mobile data for your bank login, campus portal, and the group chats where every dinner and study session gets planned. This is the step I most want new students to do early, because once it's done the rest of settling in feels easy.
With Rakuten Mobile you can apply online with just your residence card, and if your phone supports eSIM you can often be set up the same day, roughly fifteen minutes, without visiting a store. Do this after the ward office, not before you arrive, and check the official page for current terms before you apply. Sort the phone part early and you get to spend your first weeks meeting people and exploring, instead of hunting for wifi.
