What the cheap listing leaves out

In short

• Japan counts about nine million empty homes, but strip out the ones listed for rent or sale and the second homes kept in use, and the pool the headlines mean is under four million.

• Akiya banks are municipal notice boards, aggregated nationally by two private portals; they list, they do not transact, and whether a licensed broker is involved varies town by town.

• A house that no longer meets today's code is not therefore illegal: built legally, it is grandfathered, and the difference decides what you can do with it.

• Houses finished in 1999 or earlier lack the final building inspection certificate more often than not, which is a document problem before it is a building problem.

• No inspection is mandatory in a Japanese house sale; the law mandates only broker paperwork, covering whether a survey will be arranged, whether a recent one exists and what it found, and what both sides confirmed.

• The discount on a cheap house is rarely a gift. It is information about the house, priced in before you arrived.

The word akiya has done a strange journey: from a housing-policy headache to a shopping category.

The houses are real and some are worth buying. What the listings leave out is the part of the price that is not written in yen, and this article is about reading it before you pay it.

The pool is smaller than the headline

The national housing survey behind the nine-million figure also breaks it down, and the breakdown is the useful part. Once the homes already on the rental and sale markets and the deliberately kept second homes are removed, the residual is around 3.85 million, under 6 per cent of the housing stock. That smaller pool is the one the word akiya conjures. Kyoto City, against the national tide, counts fewer empty homes than five years earlier.

Where those houses surface matters as much as how many there are. The akiya banks are listing boards: municipalities approve what appears, two private portal companies run the national windows independently, and the state's own Q&A is explicit that the portals do not take part in the transaction. Whether a licensed broker stands behind a listing differs by municipality. Some towns require a brokerage mandate before a house may appear; others post owner contacts and state plainly that the town takes no part in negotiations, contracts or disputes.

That second pattern deserves a slow read.

No broker means no statutory disclosure documents, no professional on the hook for what was not said, and a price negotiated between two amateurs, one of whom has lived with the house's problems for years. It can still be a fine purchase. It is simply a purchase with the guardrails removed, and the removal is not printed on the listing.

The words that price the discount

Cheap listings speak a compact dialect, and three of its words do most of the pricing.

The first this series has already covered: 再建築不可, the plot that cannot be rebuilt, from the machiya article. The second is 既存不適格, the grandfathered building: put up legally under the rules of its day, no longer matching today's, and expressly not illegal for it, because the building code exempts what already stood when the rules changed. The distinction that matters is with a genuinely unlawful building, one that broke the rules when built; the two look identical in a photograph and sit in different legal universes. And the grandfathering has an edge: substantial extension or rebuilding brings the current code back, save for specific statutory relaxations, which is why "it stands today" never proves "it may stand again".

The third word is an absence. The 検査済証 is the certificate issued when a finished building passed its completion inspection, and for houses finished in 1999 or earlier, by the ministry's own account, more than half never received one. Its absence does not make the house unlawful, and it cannot be reissued; what fills the gap is the municipality's building-record certificate showing what was approved, plus, where needed, a specialist survey of what was actually built. Lenders read the gap their own way, bank by bank.

One date completes the dialect. Japan's seismic code changed for buildings whose confirmation was granted from 1 June 1981; the test is the confirmation date, not the completion date, so a house finished in 1982 can still be an old-code house. On a listing that names only a completion year, that question stays open, and it is answerable from the same municipal records.

The inspection nobody is obliged to run

A common myth says Japan made inspections mandatory in 2018. It did not, and the truth is more useful.

What the law actually did was put three duties on licensed brokers. In the brokerage contract, they state whether they will arrange a building-condition survey. In the statutory disclosure, they report whether a recent survey exists and, if so, its results in outline. In the contract documents, they record what both parties confirmed about the building's condition. The survey itself is voluntary, run by architects holding a specific government-registered qualification, and nobody has to commission one.

Read those three duties against the houses in this article and the design becomes visible. They exist precisely so that a buyer of an old house has a formal moment to ask for a survey, a formal place its results must be reported, and a formal record of what was and was not confirmed. On a cheap house with no certificate and an unknown code status, that machinery is the cheapest professional attention available, and it only engages where a broker is in the transaction at all, which loops back to the akiya-bank pattern above.

Use the machinery. It was built for exactly this purchase.

The running maths, honestly

Holding a cheap empty house is genuinely cheap: in the national owners' survey, about half spend under 50,000 yen a year, taxes included. The costs that bite are not the running ones.

They are the one-off exits. Renovation on a building with no inspection certificate and unknown code status starts with paying to find out what is actually there. The land discount that keeps the taxes small survives neglect only up to the point a municipality issues a formal recommendation, the mechanism the holding-costs article covers. And on the way in, a quirk of the fee rules applies at 8 million yen and under: the brokerage fee can reach 330,000 yen a side, more than the standard formula gives on anything cheaper. The rules accept that cheap houses are not cheap to transact.

None of this says do not buy. Some of these houses, machiya among them, reward exactly the buyer who documents them properly. What it says is that the discount is deferred information: the sale price of a cheap house is the part of the cost that is known, and the documents in this article are how the rest becomes known before the money moves.

The homes moogo lists for sale, at every price, come with those documents attached. They are on moogo's listings.

Questions buyers ask

Are akiya free or nearly free? Some municipalities market houses at nominal prices, usually with conditions attached, residence or renovation among them. The purchase price is the smallest number in the file either way; the survey, the paperwork and the works are the real ones.

Is a grandfathered house safe to buy? It is legal to buy and to keep. The questions are what you intend: substantial works or rebuilding bring today's code back into play, and an old-code structure earns a seismic look regardless. Legal status and physical condition are separate files.

The listing says no inspection certificate. Walk away? Not automatically; among houses finished in 1999 or earlier it is the majority condition. Ask for the building-record certificate, price in a specialist survey, and ask your lender early how they read the gap. Walk away from the seller who cannot explain the gap, not from the gap itself.

Can I buy through an akiya bank from abroad? The portals are open to anyone to search, wherever they are. The practical question is whether a broker is in the transaction, because everything the series has covered about disclosures and documents flows through one, and a municipality that lists owner contacts and steps aside leaves you to build that protection yourself.

Why is the agent's fee so high on such a cheap house? Because the fee schedule was changed to allow it: up to 330,000 yen a side on properties at 8 million or under, on the reasoning that surveying and documenting a cheap old house costs no less than an expensive one. The fee needs your agreement in advance, and it is buying exactly the work this article says these houses need.

A cheap house is a file of unanswered questions with a roof on it. Answer them before the purchase and some of these houses are the best value in Japan; skip them and the discount was never a discount. To have a specific listing read properly, tell moogo what you found.
