Cheap houses in Japan: if they are so cheap, why don't Japanese people buy them?

The low price is the answer to a different question than most foreign buyers assume

Japan has roughly 9 million vacant houses, about 13.8 percent of all housing stock as of the 2023 Housing and Land Survey. Around 3.85 million of those are in the worst category: no designated use, no maintenance, and often no clear owner. Headlines fixate on the price. A house for the cost of a used car. Sometimes free. The obvious question follows: if the deal is this good, why are the people who live here, speak the language, and understand the system leaving these houses empty?

The short answer is that cheap houses in Japan are not a bargain that locals are overlooking. Japanese buyers are pricing in costs that the sticker never shows.

A house is a depreciating asset, not an investment

In most Western markets, an older house can appreciate. In Japan, the building and the land are valued separately, and the building is treated as something that wears out. A wooden house is typically valued at close to zero after 20 to 25 years, regardless of how well it was kept. What you are paying for is almost entirely the land underneath.

This changes the math completely. A Japanese buyer looking at a cheap rural house is not looking at an asset that will grow. They are looking at a structure the market already considers worthless, sitting on land that may also be losing value because of where it is. There is no upside to waiting for.

Renovation usually costs more than the house

The purchase price is the smallest number in the transaction. Most of these houses were built decades ago, and a large share dates from before 1980. Interviews with owners of neglected vacant houses found that more than half showed decay or structural damage. Roofs, foundations, plumbing, wiring, insulation, and pest damage are common, and full renovation frequently runs to several times the purchase price.

A Japanese buyer knows this without being told. A 3 million yen house that needs 15 million yen of work is not a 3 million yen house. It is an 18 million yen project with none of the guarantees of new construction, and often in a location where the finished property will never be worth 18 million yen.

Why are cheap houses in Japan so cheap

Vacancy is not spread evenly. The highest rates are in depopulating rural prefectures: Wakayama and Tokushima at around 21 percent, followed by Kagoshima, Kochi, and Ehime. The lowest-priced houses are concentrated in rural Shikoku and Kyushu.

These are the areas young people have been leaving for decades. Work, universities, and hospitals are in Tokyo, Osaka, and Nagoya. The Greater Tokyo Area alone holds over 37 million people, roughly 30 percent of the country. A cheap house is cheap partly because almost no one with options wants to live where it is. For a Japanese family, buying one means accepting long distances to work, shrinking local services, and an aging community around them. The price reflects that trade; it does not offset it.

Demographics are working against every rural house

Japan's population peaked at about 128 million in 2008 and has been falling since. The fertility rate sits near 1.2, well below replacement, and 2023 recorded fewer than 760,000 births, the lowest since records began. Fewer people means fewer households, and the number of households is what drives housing demand.

There is already far more housing than the shrinking population needs, and the surplus is heaviest in exactly the rural areas where these houses cluster. A Japanese buyer weighing a rural house is buying into a market with permanent oversupply and falling demand. That is not a market where anyone expects to sell easily later.

Financing is difficult even for locals

Foreign buyers often hear that mortgages are hard to get. What is less discussed is that financing a cheap old rural house is difficult for Japanese buyers, too. Banks lend against the assessed value of the property, and if the building is valued near zero and the land is worth little, there is not much to lend against. Loans for old properties in depopulated areas often come with short terms and unfavorable conditions, if a bank will lend at all. Many of these purchases effectively require cash, which narrows the buyer pool sharply.

Buyers prefer new construction

There is also a straightforward cultural preference. Japanese buyers overwhelmingly favor newly built homes over second-hand ones. A new house carries warranties, current earthquake standards, and no uncertainty about hidden damage. Given the choice, most domestic buyers who can afford to build or buy new will do exactly that, which leaves the older stock sitting.

Earthquake standards matter specifically here. The current seismic code, Shin-taishin, took effect in 1981. A large portion of these cheap houses predate it, meaning they may not meet modern requirements without reinforcement. For a buyer in an earthquake country, that is a real and expensive concern, not a technicality.

Many cheap houses cannot be bought at all

Some empty houses are not on the market because no one can sell them cleanly. When an owner dies without registering an inheritance, ownership can fragment across multiple heirs. Over a generation or two, a single house can end up partially owned by dozens of relatives. Getting every one of them to agree to a sale can be so difficult that the house simply stays empty. These properties inflate the vacancy statistics while never being purchasable by anyone, local or foreign.

What does this mean for a foreign buyer

None of this means cheap houses in Japan are a bad purchase. It means the low price is information. Japanese buyers are not passing on these houses out of oversight. They are responding rationally to depreciation, renovation cost, location, demographics, financing, and legal risk.

A foreign buyer can still do well, but only by evaluating the same factors a cautious Japanese buyer would, rather than treating the price as free money. The houses that make sense are the ones where the numbers work after renovation, the location has a real reason to hold value, and the title is clean. Those exist. They are just not the same houses as the viral 500,000 yen listings, and knowing the difference is the entire task.
