Japan's Nationality Rule for Property Registration Starts October 5, 2026: What Changes for Foreign Buyers — and What Doesn't

Search for news about Japanese property in 2026 and you will find a run of headlines suggesting Japan is closing its doors to foreign buyers. If you are considering a purchase, or you are about to inherit a Japanese property, that is an unsettling thing to read.

The reality is narrower and much less dramatic. From October 5, 2026, the form used to register ownership of Japanese real estate gains one new item: the owner's nationality. You will need to prove it with a document. That is the change. Nothing about who is allowed to buy, what they are allowed to own, or what it costs is affected by it.

This guide sets out exactly what the rule requires, what it does not do, and how it sits alongside the other nationality reporting rules that came into force earlier in 2026 — several English-language sources have mixed these up, and some give the wrong start date.

At a glance

Question	Short answer
When does it start?	For ownership registrations filed on or after October 5, 2026.
Who has to declare nationality?	Every individual who becomes a registered owner — Japanese and foreign nationals alike.
Does it stop foreigners buying property in Japan?	No. There is no ban, no approval step, and no change to ownership rights.
Will my nationality be public?	No. It is held in an internal file, not shown on the public register.
What do I submit as a foreign national?	A passport copy with a Japanese translation, a residence card, a special permanent resident certificate, or a resident record showing nationality.
Does it apply to inheritance?	Yes. Registering an inherited property in your name is an ownership registration too.
I already own property. Do I have to do anything?	Not because of this rule. Existing owners may file the information voluntarily.

What exactly changes on October 5, 2026

Japan registers ownership of land and buildings at the Legal Affairs Bureau. When ownership is first recorded (所有権保存登記) or passes to a new owner (所有権移転登記), the new owner is named on the register.

Since April 21, 2025, that application has already had to include a set of search information (検索用情報) about the new owner: full name, the reading of the name (romanised for foreign nationals), address, date of birth and an email address. The Legal Affairs Bureau uses this information behind the scenes to identify owners and keep their records current. It is not printed on the register.

From October 5, 2026, the Ministry of Justice adds nationality (国籍等) to that set. The word 等 ("and similar") exists because the field also covers regions defined in Japan's immigration law rather than countries — Taiwan, and the West Bank and Gaza Strip, are recorded in this way.

So the practical effect for a buyer is one more piece of information on the application, and one more document in the bundle your judicial scrivener (司法書士) prepares.

Who it applies to

• Individuals, not companies. The declaration is made for natural persons who become registered owners. Companies are handled under separate rules, described below.
• Japanese nationals as well as foreign nationals. Everyone registering ownership declares nationality. The rule does not single out foreign buyers at the registration stage.
• Every route into ownership. A purchase, an inheritance and a gift all end in an ownership registration, so all of them are covered from October 5.
• Not retroactive for existing owners. If you are already on the register, this rule does not require you to do anything. An existing owner may choose to file search information, including nationality, as a standalone application.

If you are an overseas heir, note the interaction with inheritance registration, which has been mandatory since April 2024. An inheritance registered after October 5, 2026 will include the nationality declaration as a matter of course — see our guide to inheritance registration for foreign heirs for the rest of that paperwork.

What you have to submit

The nationality has to be supported by a document. Which one depends on your nationality, not on where you live.

If you are	Accepted proof of nationality
A Japanese national	A copy of your resident record (住民票) showing your registered domicile (本籍), or a copy of your koseki supplement (戸籍の附票)
A foreign national	Any one of: a copy of a resident record that shows your nationality or region; a copy of your passport together with a Japanese translation; your residence card (在留カード); or your special permanent resident certificate (特別永住者証明書)

For most foreign buyers living outside Japan, the passport copy with a Japanese translation will be the practical route, because a residence card and a resident record exist only for people resident in Japan.

This is separate from proving your address. A foreign national living abroad already has to supply proof of address when registering as an owner — either an official address certificate issued by the government of their home country or country of residence, or a notarised affidavit together with a copy of the passport pages showing their name, photograph and validity. The nationality document is an additional item, not a replacement.

Will your nationality be made public?

No. This is the point most worth clarifying, because it is the one people worry about.

Japan's property register is a public record: anyone can obtain a certified copy of it (登記事項証明書) for a fee, and it shows the owner's name and registered address. Nationality is not added to that record. It is stored in the Legal Affairs Bureau's search-information management file (検索用情報管理ファイル), which is an internal administrative file rather than part of the published register.

In other words, a neighbour, an estate agent or a curious member of the public looking up your property will not see your nationality.

What the rule does not change

Because the coverage has been alarmist, it is worth stating plainly what stays the same.

• Foreign nationals can still buy. Japan does not restrict ordinary residential purchases by nationality. Land, houses and condominiums can be owned outright, including the land beneath them.
• No residency or visa is required to buy. You can purchase while living abroad, and without ever having held a Japanese visa.
• There is no approval or screening step. The declaration is recorded, not reviewed as a condition of ownership.
• Ownership rights are identical. A foreign owner can sell, let, mortgage (where a lender agrees) and leave the property to heirs on the same terms as a Japanese owner.
• Taxes are unaffected. Fixed asset tax, acquisition tax and registration tax are calculated the same way regardless of nationality.

Japan's other 2026 nationality rules — and why they get confused

Much of the confusion comes from the fact that several separate rules requiring nationality information took effect in 2026. They apply to different transactions and have different start dates.

Rule	What triggers it	In force from	Affects a typical home buyer?
Nationality declaration at property registration (不動産登記)	Registering ownership of any real estate	October 5, 2026	Yes — every buyer and heir
National Land Use Planning Act notification (国土利用計画法)	Large land transactions above area thresholds	April 1, 2026	Rarely — thresholds are well above ordinary residential plots
Important Land Survey Act (重要土地等調査法)	Acquisitions within designated zones around defence facilities, border islands and similar sites	April 1, 2026	Only if the property is inside a designated zone. For companies, the nationality of the representative and of anyone holding a majority of directors or voting rights is also reported
Foreign Exchange Act report (外為法)	A transaction that crosses the resident / non-resident boundary	An existing obligation	Often — due within 20 days of acquisition. See our guide to the 20-day FEFTA report

Forest land and farmland have their own notification regimes as well, but those matter only if you are buying forest or agricultural land specifically.

If you read that nationality reporting "started in April 2026", that is true of the land-use and designated-zone rules. The requirement that reaches every ordinary property buyer is the registration change on October 5.

Why Japan is doing this

Two long-running policy concerns meet here.

The first is owner identification. Japan has a well-documented problem with land whose owners cannot be traced — property that was never re-registered after a death, or whose registered address is decades out of date. In April 2024 the government made inheritance registration mandatory and began asking overseas owners to name a domestic contact; from April 2026 it also made the registration of address changes compulsory. Collecting consistent owner information, including nationality, is part of the same effort.

The second is visibility of foreign land ownership. There has been political pressure to understand how much land is held by foreign individuals and companies. The response so far has been to measure, not to restrict — which is exactly what a disclosure requirement does.

Whether future governments go further is a political question nobody can answer with certainty. What can be said is that the rules actually in force as of 2026 require information, not permission.

What a foreign buyer should do

1. Keep your passport valid and to hand. A copy with a Japanese translation is the most practical proof of nationality for a buyer living abroad.
2. Ask your judicial scrivener early what they need. The nationality document joins the proof of address and identity documents. Collecting certified documents abroad is the slowest part of any purchase, so plan it alongside those rather than as an afterthought.
3. Plan the address proof at the same time. If you live outside Japan, your proof of address is a notarised affidavit or an official certificate from your home country — usually the longer lead-time item.
4. Arrange a domestic contact. Since April 2024, an owner living abroad is asked to register a contact in Japan (国内連絡先) — a person or company that can be reached about the property — or to state that there is none.
5. Check whether a FEFTA report is due. If the purchase crosses the resident / non-resident boundary, a report to the Minister of Finance via the Bank of Japan is due within 20 days.
6. Diarise address changes. Once you own the property, any change of address must be registered within two years. Owners living overseas cannot rely on the automatic update available to Japanese residents — see our guide to address change registration.

A note on advice

This article explains the rule in general terms so you know what to expect. It is not legal advice. Property registration in Japan is handled by judicial scriveners (司法書士), who will confirm the exact documents your case requires — particularly where nationality, residence and the route of acquisition interact, or where the property sits inside a designated zone.

How Japan YES helps

We are not a law firm and we do not file registrations. We work alongside the judicial scrivener who does, handling the ongoing side of owning Japanese property from overseas.

We can act as your domestic contact and your tax representative (納税管理人), receive and scan the post that arrives for the property, translate it into English so you can see what needs attention, and pay bills on your behalf. When you need a judicial scrivener for the purchase or a later registration, we introduce you to one rather than pretending to be one.
