In Japan, a stigmatized property is called a “jiko bukken” (事故物件), one type of “kashi bukken” (瑕疵物件, a defective property) — specifically, a property with a psychological defect. A defective property directly affects value in Japan, but the Japanese property market also has a well-developed system to protect owners’ rights. This article explains what counts as a “jiko bukken,” the laws that protect buyers and tenants, and how to check whether a property in Japan is a jiko bukken.
What Counts as a “Jiko Bukken”?
At its core, this refers to a property where a resident has died inside the home. A jiko bukken generally involves murder, suicide, or an unusual accidental death. Natural death and ordinary daily-life accidents, such as a fall or choking, are explicitly excluded from the disclosure duty under the Ministry of Land, Infrastructure, Transport and Tourism’s 2021 guideline and are not treated the same as murder or suicide. For example, if someone died in a gruesome murder, the property will almost certainly be treated, at least for a time, as a jiko bukken. But if an elderly person living with family suddenly passes away from illness and is found right away, that death generally falls outside the disclosure duty, so it will not necessarily be classified as a jiko bukken.
In other words, it is not simply “a room where someone died = a jiko bukken.” Each case is judged on its own facts, weighed against ordinary negative reactions, to decide whether it counts as a jiko bukken — and in practice, that judgment call often falls to the real estate agent.
To protect residents from this kind of unwelcome surprise, the Act on Real Estate Brokerage Business allows operators to be penalized under what is known as “liability for latent defects” (瑕疵担保責任). This liability covers defects in the property, and a jiko bukken counts as a “psychological defect.” For example, suppose you unknowingly rent a Japanese property where a previous resident died by suicide. Under the 2021 guideline, a landlord generally no longer needs to disclose that death once about three years have passed since it became known; within that window, if you learn from another resident that an undisclosed suicide occurred, or you already know it was a suicide, you may be able to seek compensation from the landlord. To guard against this risk, the law also imposes a duty to disclose within that window.
How to Check for a “Jiko Bukken”
Before buying property in Japan, overseas investors can do their homework using two common methods to check whether a property is a jiko bukken.
Method 1: Search Online
The well-known incident-tracking site “Oshima Teru” is simple to use and built on top of Google Maps. Locations where an incident has occurred are marked on the map with a “yellow fireball” icon; clicking it opens an information box explaining when, where and how the incident happened, and the site even has a community feature where people can discuss the location or read others’ comments. Using it is straightforward — just enter an address to search for information on the relevant building. That said, the site’s content is not necessarily fully accurate, so anything found there should still be verified.
Method 2: Ask a Japanese Real Estate Agent
Under Japan’s Act on Real Estate Brokerage Business, if an incident or accident has occurred in a property, the owner or the real estate agent handling the transaction is obligated to disclose this to the buyer or tenant when signing a purchase or lease agreement. When buying property in Japan, the relevant parties will also carry out a property survey, most commonly producing a document called the “Important Matters Explanation” (重要事項説明書, also known as “juusetsu”). A licensed real estate transaction manager (takken shunin) must provide this document in writing and explain its contents. As noted above, the landlord or the property’s agent must clarify whether the property has been involved in, or the site of, a death.
Beyond these methods, as a general rule, if a sale price or rent is 50% to 40% below the market average, that is also worth treating as a red flag.
