Abandoned Houses in Japan: How Many, and Can You Buy One?

How many abandoned houses are there in Japan?

The reference figure comes from the Jūtaku Tochi Tōkei Chōsa (Jūtaku Tochi Tōkei Chōsa, Housing and Land Survey), run every five years by Japan's Statistics Bureau. The 2023 edition counted about 9 million vacant dwellings, close to 14% of the housing stock, the highest share ever recorded.

That headline number is quoted everywhere, and it is almost always misread. The survey splits those 9 million into four very different categories, and only one of them matches what an English speaker calls an abandoned house.

Category (2023 survey)	Roughly	What it actually is
For rent, between tenants	4.4 million	Ordinary rental stock, empty for a few weeks or months
Other vacant homes	3.9 million	Empty, unlisted, no plan: the true akiya
Second homes and villas	0.4 million	Used a few weeks a year, owner present
Already listed for sale	0.3 million	On the market right now

The line that matters is the second one. Those 3.9 million homes are the ones with no tenant, no listing and often no clear plan, and they are the pool that municipal registries and specialist agencies draw from. When a headline says Japan is giving away 9 million houses, it is inflating the real figure by more than double.

One more correction worth making early: vacant does not mean derelict. A large share of those 3.9 million are structurally sound houses whose owner died or moved into care, and which nobody in the family wants to manage from another city. Condition varies from move in ready to beyond saving, and price alone will not tell you which one you are looking at.

Why Japan empties: the five forces behind the vacancies

Japan's vacancies are not the result of one crisis. They are the slow sum of five structural forces, and understanding them tells you which houses will keep losing value and which will not.

1. Population decline, concentrated in the countryside

Japan's population has been shrinking for over a decade, and the decline is far from even. Young adults move to Tokyo, Osaka and the regional capitals, while rural towns lose a generation at a time. The house does not disappear when the family does, so the stock stays and the occupants do not.

2. Buildings that are designed to lose value

A Japanese wooden house is treated as a depreciating asset, not a store of value. Tax depreciation for a wooden home runs over 22 years, and the market follows the same logic: after roughly 25 to 30 years, a standard house is often valued at close to zero, with the land carrying the price. An heir who inherits a 40 year old house in a shrinking town inherits maintenance, not capital. We cover the mechanics in our article on why Japanese houses lose their value.

3. A property tax that punishes demolition

This is the cause most foreign articles miss, and it is decisive. Residential land benefits from a large reduction on kotei shisan zei (kotei shisan-zei, fixed asset tax): up to one sixth of the assessed value on the first 200 m². Demolish the house and the land stops being residential, so the bill can rise sharply. For decades, the cheapest thing an owner could do was leave the building standing and rotting. Our guide to property tax in Japan sets out the rates.

4. Inheritances nobody registered

Until recently, registering an inherited property was optional. Families skipped it, generation after generation, and the result is houses with a dozen legal co-owners scattered across the country, several of whom may be deceased in turn. Nobody can sell, so nothing is sold. Japan made inheritance registration compulsory on 1 April 2024, with a deadline of three years and a fine for missing it, which should slowly drain this category. It does not fix the existing backlog.

5. A cultural preference for new

Japanese buyers have long favoured shinchiku (新築, newly built) over second hand, so an ageing house in a rural town faces a thin domestic market. That preference is softening in the cities, but it still shapes what sells in the countryside.

Where the abandoned houses actually are

Vacancy is a rural phenomenon with a few urban exceptions. The national rate is close to 14%, but the spread between prefectures is wide enough to change an investment case completely.

Prefecture	Vacancy rate (2023, rounded)	What that means for a buyer
Wakayama	around 21%	Highest in the country, deep supply, coastal towns within reach of Osaka
Tokushima	around 21%	Shikoku, very low prices, thin rental demand
Yamanashi	around 20%	Many second homes near Mount Fuji, Tokyo commuter belt at the edges
Kagoshima, Kōchi, Ehime	around 20%	Rural Kyushu and Shikoku, cheapest stock in Japan
Nagano	around 20%	Mountain and onsen towns, real tourist demand in specific valleys
Tokyo	around 11%	Mostly rentals between tenants, very few true akiya
Kanagawa, Saitama	around 9 to 10%	Lowest rates, commuter belt, prices hold

Read that table twice, because it contains the central trap of the whole subject: the prefectures with the most abandoned houses are the prefectures where the fewest people want to live. High vacancy is not an opportunity in itself, it is a measure of departure.

The exceptions are what make the market interesting. Wakayama combines the highest vacancy in Japan with coastal towns roughly two hours from Osaka, which is why it is consistently the largest source of listings in our own catalogue: you can see the current stock on our Wakayama page. Nagano's onsen valleys carry genuine tourist demand. Around the edges of Yamanashi, a house can be both cheap and within commuting distance of the Tokyo area.

Our advice is the same one we give on every rural purchase: the location decides, the building only follows. A sound house 40 minutes from the nearest station in a town with no shop is worth less than a wreck 10 minutes from a working line. If the countryside is what draws you, read our piece on buying in the Japanese countryside before you fall for a photograph.

Akiya, vacant, abandoned: the words that change the price

Japanese listings use a precise vocabulary, and the English word abandoned covers at least four situations that carry very different prices and risks. Learning these five terms will save you more money than any negotiation.

Term	Japanese	What it means for you
akiya	akiya	Any vacant home. Says nothing about condition or price
akiya banku	akiya bank	A municipal registry matching owners with buyers, often with residency conditions
tokutei akiya	tokutei akiya	Officially designated as dangerous or unsanitary. The tax break is removed and the town can order works, or demolish at the owner's cost
kanri fuzen akiya	kanri fuzen akiya	Added by the 2023 reform: poorly maintained, one step before the above, and already enough to lose the tax break
saikenchiku fuka	saikenchiku fuka	Cannot be rebuilt. The plot fails the road access rule, so once the house is gone, nothing legal replaces it

The last two lines are where cheap houses become expensive. A tokutei akiya designation means a municipality has already judged the building a hazard, and that judgment transfers to you with the deed. A saikenchiku fuka plot is worse in a quieter way: the house you buy is the last house that plot will ever legally carry, so your renovation budget is not a choice, it is the only path.

Two practical notes. A municipal akiya banku is not a bargain bin: many registries require you to move in, to commit to a minimum stay, or to be under a certain age, and the paperwork is Japanese only. We explain how these registries actually work in our guide to the akiya bank. And the famous free house is rarely free: our article on the 1 yen akiya works through the real total.

Can a foreigner buy an abandoned house in Japan?

Yes, and this is the part that surprises most readers. Japan places no nationality restriction on property ownership. A foreign buyer acquires the same freehold title as a Japanese national, including the land, with no residency requirement, no local partner and no approval process. There is no equivalent of the leasehold or nominee structures used elsewhere in Asia.

Three limits matter far more than nationality, and they are where realistic planning starts.

Buying gives you no right to stay

This is the single most common misunderstanding, and it is worth stating flatly: owning property in Japan grants no visa and no residence right of any kind. You will own the house and still enter the country on whatever status you already hold, tourist stay included. There is no investor visa attached to real estate. Our article on buying a house in Japan without a visa covers what is and is not possible.

Financing is effectively cash

Japanese mortgages are in practice reserved for people who both live in Japan and are employed there, with a residence card and a local income history. A non resident buying an abandoned house should plan on paying cash. In this market that is less punishing than it sounds, since the sums involved are small by international standards, but it has to be planned rather than discovered.

Distance is the real cost

Nationality is free, absence is not. Someone has to view the property, read a Japanese contract, attend the jūyō jikō setsumei (jūyō jikō setsumei, the mandatory legal briefing before signing), coordinate trades and receive the keys. Doing that from abroad is the actual difficulty of an akiya purchase, and it is what our end to end support package exists for. The full sequence is set out in our guide to buying a house in Japan.

What an abandoned house really costs: a worked example

Take a real world case: a wooden house of about 100 m², built in the 1970s, in a Wakayama coastal town 15 minutes from a station, listed at 3,000,000 yen (about $19,200). Here is what it costs to make it habitable, with the numbers a buyer actually signs.

Item	Yen	USD (approx.)
Asking price	3,000,000	$19,200
Purchase costs (agency, registration, taxes, at most 6%)	180,000	$1,150
Clearing the contents left behind	300,000	$1,900
Roof and structural timber	2,500,000	$16,000
Plumbing, wiring, kitchen and bathroom	2,000,000	$12,800
Insulation and joinery	1,500,000	$9,600
Total to habitable	9,480,000	about $60,800

The lesson is in the ratio: the advertised price is under a third of what the project costs. Anyone budgeting from the listing alone is budgeting for a quarter of the reality. Add annual holding costs of roughly 50,000 to 100,000 yen ($320 to $640) in property tax for a house of this size in a rural town, plus insurance.

Note also what the 6% ceiling covers. Total purchase costs in Japan, meaning agency commission, registration tax, the judicial scrivener's fee and acquisition tax, stay at or under 6% of the price. That is low by European standards and it is one of the genuine advantages of this market. The renovation, not the transaction, is what costs money. Our detailed figures are in the cost of renovating a machiya or kominka.

One reassurance on the structure: a house built before 1981 falls under the old seismic code, and that is not automatically a rejection, but it is a line item. Reinforcement work is common and quantifiable, and our article on the 1981 seismic standard explains what to check and what it costs.

The five traps that turn a cheap house into an expensive one

Every trap below has cost a real buyer real money. None of them is visible in a listing photograph.

1. The plot that cannot be rebuilt

Saikenchiku fuka plots fail the rule requiring at least 2 m of frontage onto a road of 4 m or more. Demolish and you own land you cannot build on, worth a fraction of what you paid. Always check road access before anything else.

2. An unregistered inheritance

If the deed still names a grandparent, every living heir must consent to the sale. Tracing eight relatives across four prefectures can take a year, and one refusal ends it. Ask who is on the tōki bo (tōki簿, the land register) before you spend a yen.

3. The tax break you inherit without

If the house is already designated kanri fuzen or tokutei akiya, the residential reduction on the land may be gone. The holding cost you modelled can be several times what you expected from day one.

4. Contents, and the cost of removing them

Japanese homes are very often sold with everything still inside, from furniture to a lifetime of belongings. Clearing a full house runs from 200,000 to 500,000 yen ($1,300 to $3,200), and it is rarely mentioned in the price.

5. A town with no trades left

In depopulated areas the carpenter, the roofer and the plumber may be an hour away and booked for months. The quote is not the only problem: the calendar is. Confirm that the work can actually be carried out before you commit to the purchase.

Common mistakes to avoid

• Buying the building instead of the location. The house is the depreciating part, the land and the access are what hold value. A sound wreck near a working station beats a pretty house in a town with no shop.
• Reading 9 million as 9 million for sale. Only about 3.9 million are genuinely idle, and only a fraction of those are actually available to a foreign buyer today.
• Budgeting from the asking price. As the worked example shows, the listing is often under a third of the project.
• Assuming an akiya bank is the cheapest route. Municipal registries frequently attach residency or occupancy conditions that make them unusable for a non resident.
• Expecting a mortgage. Without residence and Japanese employment, plan for cash.
• Expecting a visa. The purchase changes nothing about your immigration status.
• Skipping the survey because the price is low. A 3,000,000 yen house with a failed roof is not a cheap house, it is a 9,000,000 yen project.

If you want to see what is genuinely on the market rather than what circulates on social media, our catalogue lists vacant homes across Japan with the analysis attached: browse the current akiya listings, the stock under $50,000, or the kominka for sale if a traditional farmhouse is what you are after.

Conclusion: abandoned is a condition, not a bargain

Japan's 9 million vacant homes are real, and so are the 3.9 million that sit genuinely idle. What is not real is the idea that a country is giving away houses. Those homes emptied for reasons that have not gone away: a shrinking rural population, buildings that depreciate by design, a property tax that rewarded leaving them standing, and inheritances nobody could untangle.

That does not make them a bad purchase. It makes them a purchase with a known shape. A vacant house bought for its location, surveyed honestly, budgeted at three times its asking price and renovated by trades who can actually reach it is one of the few places in the developed world where a modest sum still buys a real home with full freehold title. A vacant house bought for its price alone is a liability with a roof.

The difference between the two is due diligence, and most of it has to happen in Japanese, on the ground, before you commit. That is the part we handle: from finding the property to handing over the keys, through our support package, or on your own with the full method in our buying guide and the deeper reading in buying an akiya in Japan.

Frequently asked questions

How many abandoned houses are there in Japan?

The 2023 Housing and Land Survey counted about 9 million vacant dwellings, close to 14% of the housing stock. Of those, roughly 3.9 million are genuinely idle: empty, unlisted and with no plan. The rest are rentals between tenants, second homes, or properties already for sale.

Can foreigners buy abandoned houses in Japan?

Yes. Japan places no nationality restriction on property ownership, and a foreign buyer gets the same freehold title to the building and the land as a Japanese national. No residency, local partner or government approval is required. The practical obstacles are financing and distance, not nationality.

Are abandoned houses in Japan really free?

Almost never. A handful of properties are listed at 1 yen or given away, but the transfer carries the liabilities: back taxes, clearing the contents, repairs, and sometimes a plot that cannot legally be rebuilt on. Budget the total project, not the headline price.

Why are there so many abandoned houses in Japan?

Five forces combine: a shrinking and concentrating population, wooden houses that are treated as depreciating assets, a property tax break that made demolition expensive, inheritances that were never registered, and a domestic preference for new builds over second hand homes.

Does buying a house in Japan give you a visa?

No. Owning property in Japan grants no residence right and no visa of any kind. There is no investor visa attached to real estate. You will own the house and still need an immigration status obtained on its own merits to live in the country.

How much does it cost to renovate an abandoned Japanese house?

For a 100 m² wooden house needing roof, plumbing, wiring and insulation, plan on 5,000,000 to 7,000,000 yen (about $32,000 to $45,000). A realistic rule of thumb is that the finished project costs roughly three times the asking price of a cheap akiya.

Can you get a mortgage to buy an akiya?

In practice, only if you live in Japan and are employed there, with a residence card and a local income history. Japanese banks rarely lend to non residents, and the small loan amounts involved make akiya financing unattractive to them. Most foreign buyers pay cash.

What happens if an abandoned house is left to rot?

A municipality can designate it kanri fuzen akiya, poorly maintained, or tokutei akiya, dangerous or unsanitary. Either designation removes the residential reduction on the land tax. In the most serious cases the town can order works or demolish the building and bill the owner.
