What jiko bukken means, what agents are required to disclose under the Japanese Ministry of Land's 2021 guidelines, how to check the Oshimaland map yourself, and whether buying one at a 20-30% discount is worthwhile.
Vietnamese people viewing homes in Japan often come across this situation: an apartment in a great location with decent furnishings is priced 20–30% below similar properties nearby. Before celebrating, ask one important question: could this be a 事故物件 (jiko bukken)? — a property where someone died an unnatural death.
What is a 事故物件?
Jiko bukken (物件 = property, 事故 = incident) refers to a house or apartment where there has been a murder, suicide, fatal fire, or a death that went undiscovered for an extended period. Japanese culture is particularly wary of these properties, so their sale and rental prices can drop sharply — which is also why they have become a niche that some investors are willing to enter.
What are agents REQUIRED to disclose to you?
In October 2021, Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) issued official guidelines on disclosure obligations, 「人の死の告知に関するガイドライン」. Here is the key information you need to remember:
| Situation | Is the agent required to disclose it? |
|---|---|
| Murder, suicide, or a fatal fire inside the property | Must be disclosed when SELLING — no time limit |
| The above, when RENTING OUT | Must be disclosed for approximately 3 years from the date of the incident |
| Natural death from old age or illness (discovered promptly) | Not mandatory |
| Natural death discovered late (requiring special cleanup) | Must be disclosed like the first category |
| An incident in a shared area (hallway, elevator, etc.) | Usually must be disclosed if asked |
The most important point: if you ASK directly, the agent is not allowed to lie — even if more than 3 years have passed. So when viewing a property, always ask this question (you can even show the agent the original wording):
この物件で過去に人の死（自殺・他殺・孤独死など）はありましたか？ (Has anyone died at this property in the past — by suicide, murder, or an unattended death?)
Check it yourself with the Oshimaland map
Oshimaland (大島てる) is Japan's best-known community map of jiko bukken — each 🔥 flame on the map marks an address where an incident has occurred, along with a description and source. How to use it:
- Open the map and zoom in on the area where you plan to buy or rent.
- Click the flame icon near the address to read the details (date and type of incident).
- Keep in mind that this is community-contributed data — it may be incomplete or inaccurate, so use it for cross-checking, not as a substitute for asking the agent directly.
Tip: check the neighboring buildings as well — an incident in another unit of the same building may not have to be disclosed, but it can affect your property's resale value later.
Should you buy a jiko bukken as an investment?
- Pros: the purchase price is 10–30% lower; after a few years and one tenant cycle, the stigma gradually fades; rental yields calculated against the lower purchase price can be significantly higher.
- Cons: resale is difficult, and disclosure is still required when selling (permanently for murder or suicide); some banks are reluctant to lend; Japanese tenants can be selective, often requiring a rental discount of around ~10–20%.
- OlaChill's conclusion: for a home to live in yourself, it depends on your family's level of comfort with spiritual concerns; as a rental investment, it is a genuine niche, but you need to plan your exit from the moment you buy.
