The Documents to Prepare Before You Move to Japan
Updated: 2026-08-22
Quick answer
Hi, I'm Miya. Before you fly to Japan, gather five things: your passport, your Certificate of Eligibility or visa, proof of why you're coming (an enrollment letter or employment contract), a few spare ID photos, and clean copies of everything. Sort these at home, calmly, while you still have easy access to printers, embassies and your home records.
None of this is exciting, but it's the foundation for everything you'll do in your first weeks. The single most important document — your residence card — you can't prepare in advance. It's handed to you on arrival, and almost every next step depends on it. So the goal before you leave is simple: arrive with a paperwork trail so clean that getting that card is effortless.
Your passport and the visa inside it
Your passport is the anchor for every other document, so check it first. Make sure it stays valid comfortably beyond your planned stay, and that there's at least one clean page for the entry sticker. If it's close to expiring, renew it before you apply for anything else — a new passport number can ripple through the rest of your paperwork.
If your country needs a visa, it will be placed in your passport by a Japanese embassy or consulate before you travel. The visa is what lets you board and enter; it is not the same as the residence card you'll receive later. Keep the passport somewhere safe during the flight, because it's the very first thing an immigration officer will ask to see.
Certificate of Eligibility and proof of purpose
Most people moving to Japan for study or work first receive a Certificate of Eligibility (COE). Your school or employer usually applies for it on your behalf, then sends you the original. Carry that original with you — not just a photo of it — because you'll present it during your visa application and again when you land.
Alongside the COE, bring the document that explains your purpose: a letter of acceptance from your university or language school, or a signed employment contract. These prove your story is consistent from the embassy counter to the immigration desk. When your paperwork all tells the same tidy tale, arrival goes smoothly and your residence card is issued without friction.
ID photos, copies and the boring-but-vital extras
Bring several spare ID photos in the standard size, taken recently against a plain background. Japan asks for photos on all sorts of applications — residence procedures, transport passes, student or staff cards — and having a small stack saves you hunting for a photo booth in your first jet-lagged week.
Then make copies. Photocopy your passport photo page, your visa, and your COE, and keep one physical set plus a scanned set in the cloud. If an original is ever lost or held for processing, copies keep you moving. Also jot down your home address and a couple of family contact details, since some arrival forms ask for them.
Why the residence card changes everything
Here's the part worth understanding before you go. When you land at a major airport as a mid- to long-term resident, immigration issues your residence card on the spot, using the very documents you prepared. That card is your official proof of identity and status for daily life in Japan.
From there, a chain unlocks. You take the card to your local ward or city office to register your address, which is a prerequisite for so much else. With your address registered and card in hand, you can open a bank account and sign up for a Japanese mobile number. Everything you packed at home exists to make that one card appear quickly and correctly.
A gentle note on staying connected
One last thing from me, Miya. You can't contract a Japanese SIM before you land — a domestic number is tied to that residence card you'll only hold once you arrive. So plan your pre-departure paperwork now, and simply keep connectivity on your short list for day one.
Once you have your card, getting a Japanese number is one of the first things worth sorting, because your address registration, banking and app sign-ups all lean on it. Rakuten Mobile, for instance, can be applied for online with just your residence card, and an eSIM can be issued the same day — so you're reachable soon after you touch down. Prepare the papers, land, get the card, then get connected.
