How To Check If A Japanese Property Is A Stigmatized Property

The actual legal hook: Article 47 of the Real Estate Brokerage Act

Japan has no statute that lists "past deaths" as a mandatory disclosure item the way it lists mortgages or zoning. The duty comes from a more general rule: the Real Estate Brokerage Act (宅地建物取引業法), Article 47, item 1, prohibits a licensed agent from intentionally failing to disclose, or misrepresenting, an important matter (重要な事項) that would materially affect the other party's decision to enter into the transaction. Courts and industry practice have long treated a past death that would unsettle a reasonable buyer or tenant as capable of being exactly that kind of "important matter" — which is what makes a jiko bukken a legal disclosure question rather than just a cultural taboo. Article 47 only bites on intentional concealment; an agent who genuinely did not know about a past incident has not violated it, which is one reason to ask the question directly rather than assume it will surface on its own.

The 2021 MLIT guideline that put a shape on that duty

For decades, how far that duty actually reached was left to case-by-case litigation, which made the practical rule hard to predict for agents and buyers alike. In October 2021, Japan's Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, MLIT) issued the Guideline on Disclosure of Human Death by Real Estate Transaction Business Operators (宅地建物取引業者による人の死の告知に関するガイドライン) to give agents a consistent basis for applying Article 47 to this specific fact pattern. It is not itself a statute — it does not create a new legal obligation — but it is now the reference point the industry and courts use for what "reasonable" disclosure looks like under Article 47. It covers residential sales and rentals, and applies to the unit itself plus common areas that residents ordinarily pass through day to day, such as an entrance, corridor, or elevator — not, generally, to other units in the same building or to common areas nobody normally uses.

What generally does not need disclosure

A natural death, or an ordinary accident in daily life — a fall, choking, a death from illness discovered in a normal timeframe — generally does not need to be disclosed under the guideline, regardless of how long ago it happened or how it is discovered. Death itself is treated as an ordinary, foreseeable part of occupying a home, not a defect. This is the single most common misunderstanding foreign buyers have about jiko bukken: the mere fact that a previous occupant died in the home, on its own, is not what triggers a disclosure duty.

What generally does need disclosure — and for how long

A non-natural death — suicide, homicide, an accidental death from crime, or a death by fire — is treated as a genuine psychological defect and generally needs to be disclosed. So does a death that was not discovered for an extended period (孤独死 or 孤立死, a "lonely death") if it required tokushu seisou (特殊清掃, specialized cleaning to remediate the effects of a decomposed body) — the extended discovery and its aftermath, not the natural death itself, is what makes this category different from an ordinary natural death. Here the sale-versus-rental distinction matters:

• Rental: the guideline gives roughly three years as a reference period after such an incident, after which the agent generally need not keep disclosing it to a new prospective tenant.
• Sale: the guideline sets no such time limit. The general, case-by-case Article 47 duty continues to apply — a genuinely material incident from many years ago can still need disclosure to a buyer, because a purchase is a far larger and more permanent commitment than a lease.

There is one override on top of both categories: if an incident became widely known — heavy news coverage, a case that stayed notorious in the neighborhood — disclosure is generally still required regardless of how much time has passed or which category it would otherwise fall into. A landlord or seller cannot rely on the passage of time to bury a case everyone already knows about.

Here is a practical way to check before you commit to a specific property:

1. Ask the agent directly, in writing, whether any death has occurred on the property or in commonly used shared areas of the building. Do not rely on a listing's English translation to have surfaced this — ask the direct question yourself, and ask again if the first answer feels vague or rehearsed.
2. If the agent confirms an incident, ask what kind and roughly when. A natural death generally does not need to keep being disclosed under the guideline; a non-natural death or a lonely death requiring specialized cleaning does, and — for a purchase — does not automatically stop needing disclosure after three years the way a rental listing might treat it.
3. Treat unusually cheap pricing or vague listing language as a prompt to ask, not a conclusion. A price meaningfully under comparable listings, or wording like "訳あり" ("for a reason") without elaboration, is a common pattern around jiko bukken in the Japanese market — see our red flags guide for other listing signals worth the same scrutiny.
4. Cross-check against Oshimaland (大島てる, oshimaland.co.jp), a free, crowdsourced, searchable map of reported incident properties across Japan. It is not an official or exhaustive source — reports are submitted by the public and not verified by any authority, and plenty of real incidents are never added — so use it as one more data point, not a substitute for asking your agent directly.
5. For a long-vacant house or akiya, ask specifically why it sat empty. A stigmatized history is one of several reasons an otherwise liveable house ends up abandoned; see our akiya guide for the others.
6. If the agent is unresponsive or evasive on a direct, written question, treat that itself as a signal, and consider asking a local judicial scrivener (司法書士) or bilingual agent to press the question on your behalf before you sign anything.
7. Still order the registration record separately. It will not show any of this — it never has and never will — but it remains how you confirm the registered owner and check for a mortgage or other encumbrance, in parallel with the disclosure question.

The most common mistake is assuming a clean-looking listing and a clean registration record mean there is nothing left to ask about. The registry answers a completely different question than the one a stigmatized-property check is asking.

What the registry can and cannot tell you here:

• What it shows reliably: the registered owner, and any mortgage or other registered encumbrance against the property. Nothing about this changes because a property is or isn't a jiko bukken.
• What it does not show: whether anyone has died on the property, under what circumstances, or when. Psychological defects of this kind are not filed with the Legal Affairs Bureau under any system — they are a matter of agent and seller disclosure duty under the Real Estate Brokerage Act, not registry law.
• How to check it instead: a direct, written question to the listing agent, cross-checked against a public resource like Oshimaland where relevant, and — for anything unresolved or evasive — a local professional who can press the question on your behalf.
• How to order the registry side, in parallel: On Japan Property Research, a property's registration record is ¥1,500 per land or building record. It confirms ownership and any registered mortgage while you separately pursue the disclosure question through your agent.

Neither check replaces the other. A clean registration record says nothing about a property's history of this kind, and a clean disclosure answer says nothing about who legally owns the property or whether it is mortgaged. Our Japan property due diligence checklist covers where both fit alongside the rest of a purchase's review.

FAQ

Does a Japanese property's registration record show if someone died there? No. A past death — natural or otherwise — is never filed at the Legal Affairs Bureau. It is a matter of the seller's agent's disclosure duty under Article 47 of the Real Estate Brokerage Act, not something the registry tracks.

Is a seller or agent legally required to tell me if someone died in the house I'm buying? It depends on the circumstances. A natural death or an ordinary accident generally does not need to be disclosed, regardless of how long ago it happened. A non-natural death (suicide, homicide, death by fire) or a death not discovered for an extended period that required specialized cleaning generally does need to be disclosed for a sale, with no fixed time limit — unlike a rental, where the reference period is roughly three years. A case that became widely known generally must be disclosed regardless of the category or how much time has passed.

What is Oshimaland, and can I rely on it? Oshimaland (大島てる, oshimaland.co.jp) is a free, public, crowdsourced map of reported incident properties across Japan, searchable in English. It is not an official government or industry source, reports are unverified, and coverage is incomplete — treat it as a supplementary check, not a substitute for asking your agent directly.

Does this apply to akiya (abandoned houses) too? Yes, and it is worth asking about specifically. A stigmatized history is one of several reasons a house sits vacant long enough to become an akiya; see our akiya guide for the fuller picture of what to check before buying one.

If I find out after closing that the property was a jiko bukken, do I have any recourse? That depends on what the seller and agent knew and disclosed, and is a question for a lawyer or judicial scrivener familiar with the facts — this guide explains the disclosure framework, not how to pursue a specific claim.

A note on scope: the roughly-three-year reference period and the "widely known" override are stated in the guideline itself, not in the statute — they describe what MLIT considers a reasonable application of the existing Article 47 duty, not a separate legal deadline. Courts remain free to reach a different conclusion on the specific facts of a case. For anything genuinely contested — a seller who disputes what they knew, or a buyer who discovers an undisclosed incident after closing — confirm the path forward with a lawyer or judicial scrivener (司法書士) rather than relying on the guideline's reference periods as a hard rule.
