Inviting Your Family to Visit Japan: Invitation Letters and Guarantor Documents

Quick answer

Hi, I'm Miya, and I help newcomers settle into life in Japan. When your parents or relatives want to come and see you here, the first question is whether they need a visa at all, and that depends entirely on their nationality — the Ministry of Foreign Affairs publishes the current list. If they do need one, they apply themselves at the Japanese embassy or consulate that covers where they live, and you prepare the Japan side: a letter of invitation, a schedule of their stay, and in many cases a letter of guarantee with documents about you. You send the originals to them, they submit everything together, and you start earlier than feels necessary.

First, find out whether a visa is needed at all

Nationality decides this, not your situation or theirs. Japan has visa exemption arrangements with a number of countries and regions, and if your relative holds a passport covered by one of them, they can come for a short visit without applying for anything, and none of the paperwork below applies to you. The Ministry of Foreign Affairs keeps the current list on its own pages, along with the conditions attached to each arrangement, which are not identical. Check there before you do anything else, because the answer decides whether the next couple of months involve envelopes or not.

If a visa is needed, the category for a family visit is short stay — tourism, visiting relatives and friends, and similar purposes. It does not permit paid work. The application is made by your relative at the Japanese embassy or consulate general with jurisdiction over their place of residence, which is not always the nearest one or the one in the capital. Each mission publishes its own list of required documents, and that list is the one that counts, over anything you read elsewhere, including this page. In some countries applications are accepted only through accredited travel agencies rather than over the counter.

Two more things worth knowing before you start. A visa is permission to travel to Japan and ask to be let in; landing permission itself is decided by the immigration officer at the airport when they arrive. And the online arrival procedures your relatives will hear about are a separate step they handle shortly before flying, not part of the visa application. None of what follows is legal or immigration advice — I'm describing the shape of the process so it looks less alarming, and the embassy's own guidance is what you should follow.

Who prepares what, and who submits it

There are two sides to the packet. Your relative handles their own half: the application form, their passport, a photograph, and whatever personal documents the embassy lists. You handle the Japan half. You are the inviter — the person asking them to come — and quite often you are also the guarantor, the person who signs the embassy's guarantee form. Those two roles can belong to different people; an individual can invite while a company or another person guarantees. If you are a resident here inviting your own parents, you will usually be both at once.

Nothing you prepare gets filed with anyone in Japan. For a short visit there is no application you submit from this end and no certificate to obtain in advance. Everything you write is supporting material for their application abroad, which means it has to physically reach them — or reach them electronically, where the mission allows that — before their appointment. That single fact sets the whole schedule. Your documents need to be complete, signed and on their way while your family still has room to submit, reschedule if something is missing, and wait for a decision without watching a departure date.

The letter of invitation and the schedule of stay

The letter of invitation explains who you are, how you are related to the applicant, why you are inviting them, and for how long. The Ministry of Foreign Affairs publishes a form for it, and the embassy's page links to the version it wants, so filling in the official form is far easier than composing something from scratch. You date it and sign it yourself. I am deliberately not giving you wording to copy, because a letter that reads like a template helps nobody; what matters is that it is true, specific to your household, and written in your own voice.

The schedule of stay is a table rather than a letter: dates, where your family will be on each of them, roughly what they will be doing, and contact details for wherever they are sleeping. If they are staying with you the whole time, that is your address and phone number down the page. If there is a trip in the middle, name the town and the accommodation. It does not need to be a finished itinerary — plans change and everyone knows it — but it should not contradict the flight dates written elsewhere in the packet.

Consistency across the whole set is the part people underestimate. Names should appear exactly as they are printed in the passport, including middle names and the order of surname and given name. Dates should be written the same way everywhere. The relationship should be described the same way in every document. Before you seal the envelope, read your own papers side by side as if you were the person checking them, because a mismatch that takes you ten seconds to fix here can cost your family an appointment and a second trip to the embassy.

The letter of guarantee and what a guarantor is asked for

When the embassy asks for a guarantee, you complete their letter of guarantee — again an official form, downloaded from the Ministry of Foreign Affairs or from the mission's own page. It records that you take on responsibility for certain matters connected with the visit, and the form's own text sets out exactly which ones. I would rather you read that text on the form than take a paraphrase from me, and I am not going to write sample sentences for it. Sign and date it yourself, and read it properly first, the way you would read anything with your name at the bottom.

Alongside it, missions commonly ask the guarantor for documents in two families: proof that you live here, and proof that you are in a position to support a visit. In practice that tends to mean a certificate of residence from your city hall, a copy of your residence card, and something about your income or employment — a municipal tax certificate or tax payment certificate, a certificate of employment, or a copy of a tax return, depending on what is listed. Documents showing the family relationship are often requested too. The exact combination differs by mission and by circumstances.

A few practical notes. City hall certificates are usually only accepted if recently issued, and the embassy states how recent, so do not collect them months ahead of the appointment. Check whether originals are required or whether copies are acceptable, because that changes what you post. If your name is written differently across your documents, expect a question about it and be ready to explain. And whether a guarantee is required at all varies with the case, so read the list before you spend an afternoon at the municipal office.

Sending the packet, and giving it enough time

Once everything is signed, keep a scan or a photo of every single page before it leaves your hands. If one document is queried, you will be reissuing it from Japan while your family waits abroad, and having the original in front of you makes that a short task instead of a long one. Send the packet by a tracked international service rather than ordinary post, so you can both see where it is, and tell your family roughly when to expect it so nobody is refreshing a mailbox for a week wondering whether it was lost.

On timing, I am not going to give you a number of days, because processing varies by mission, by season and by the individual case, and the embassy's page is the only place with an answer that is actually current. What I can say is this: have your family check the appointment situation at their embassy before anything else, allow weeks rather than days for documents to travel, and assume the busy travel seasons are busier at the counter too. Above all, do not buy non-refundable tickets before the visa is in the passport.

The decision itself rests with the embassy, and it is made on the application as a whole rather than on any one document you wrote. Your job is to give your family a clean, consistent, honestly described set of papers and then let the process run at its own pace. If anything about your family's particular circumstances is unclear, ask the embassy directly, or talk to a qualified professional here — that is a conversation about their situation, not something to settle from a guide like this one.

A reachable number belongs on those forms

Your phone number appears in this process more often than you would guess: on the letter of invitation, down the accommodation column of the schedule of stay, and on the guarantee documents if you sign them. Missions do sometimes contact the inviter or guarantor directly to confirm a detail, by phone or by email, at Japanese office hours. Your family will also want to reach you while they are queuing at the embassy, and again from the airport at the other end. A Japanese number that rings on the phone in your pocket is genuinely part of the paperwork.

After the visa is issued, the rest of it runs through that same phone from here. You will be the one booking flights, comparing trains, reserving a room near you for the nights your home cannot hold everyone, and fielding messages at odd hours while your relatives pack. Japanese travel and payment services register you against a Japanese phone number, and confirmations arrive there. Setting that up is refreshingly simple: you apply online with your residence card, and eSIM-capable phones can often connect the same day, typically in about fifteen minutes.

Have a look at our setup guide for eligibility and the step-by-step, and confirm current terms on the page before you apply. With a line in place, the rest is just a sequence you can work through calmly: check the exemption list, read the embassy's document list, download the forms, gather your certificates, post the packet, and let your family submit it. I'll be right here if you want to get the phone side sorted before the envelopes start moving.
