Jiko Bukken: Tokyo's Cheapest Legal Apartments Explained (2026)

There is a category of apartments in Tokyo that most expats have never heard of, yet it offers some of the best value rents in central areas. They are called jiko bukken (事故物件), literally "incident properties." Legal, often centrally located, and up to 30% cheaper than comparable units: here is what you need to know.

What is a jiko bukken?

A jiko bukken is a property where a "particular incident" has occurred. In Japanese law, the term is broad: it can refer to a suicide, a homicide, a solitary death discovered after several days, or a serious domestic accident.

This is not an illegal or shameful category in Japanese law. It is simply a transparency obligation imposed by regulation.

What Japanese law requires:

Under guidelines from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), landlords and agencies are legally required to disclose any significant incident that occurred in a property for the first 3 years following the event. After 3 years, the disclosure obligation expires.

Why this is an opportunity for foreigners

Japanese culture places considerable importance on the concept of "ke" (impurity) and "en" (karmic connection). For many Japanese people, the idea of living in an apartment where someone has died is psychologically difficult, regardless of how much time has passed.

This cultural sensitivity has a direct market effect: landlords struggle to rent these properties at market rate, even years after the event. They are therefore forced to offer significant discounts.

Observed discounts:

• Suicide or homicide (under 1 year): 30 to 50% below market rate
• Solitary death discovered after delay (1 to 3 years): 10 to 25% below market
• After 3 years (no legal disclosure required): 5 to 15% below market depending on landlord sensitivity

For a central Tokyo apartment at 120,000 JPY/month, a 25% discount saves 30,000 JPY per month, 360,000 JPY per year.

How to find a jiko bukken in Tokyo

Contrary to what you might expect, these properties are not hard to find if you know where to look.

Specialist websites:

• Oshimaland (大島てる): Japan's reference site for jiko bukken. A collaborative Google Maps listing records reported incidents across the city, with addresses and the nature of each event.
• JikoBukken.net: rental and sale listings with incident history.

Local estate agencies:

Some agencies specialise exclusively in these properties. Asking a general agency directly whether they have "jiko bukken" will sometimes get a positive response.

Standard portals:

Properties occasionally appear on Suumo or Homes with the notation 心理的瑕疵あり (psychological defect), which means jiko bukken without using the term directly.

What to check before signing

A jiko bukken is not a property to avoid on principle, but it requires careful verification.

1. The exact nature of the incident. A natural death from old age is very different from a homicide. Request the official disclosure document (kikakusho) and have it translated if necessary.

2. The condition of the apartment. Ask whether a specialist cleaning (特殊清掃) has been carried out. This is almost always done before properties are re-let, but confirm it explicitly.

3. Building dynamics. In some buildings, neighbours are aware of the history. If you are sensitive to that kind of social context, choose a large anonymous building rather than a small 4-unit residence.

4. Availability of documentation. A landlord or agency that refuses to provide complete documentation about the incident is a red flag.

Jiko bukken vs standard apartment: what actually changes

Most Western expats who have lived in a jiko bukken report the same thing: after the first few weeks, the apartment is just... an apartment. The walls, floor, and ceiling are the same.

What concretely changes:

• The rent, durably below market rate
• Sometimes a more favourable negotiation on move-in costs (the landlord has less leverage)
• In rare cases, initially slightly distant behaviour from neighbours

What does not change:

• The building quality
• Transport, neighbourhood, views
• The legality of your lease and your tenant rights

Practical advice

A jiko bukken is worth considering seriously if:

• You are looking for a centrally located apartment on a limited budget
• You are not particularly superstitious
• You want a quality apartment without paying the "flawless history" premium

If the psychological aspect bothers you, it is better not to go there. An apartment where you sleep badly every night is not worth the discount.

For everyone else: it is one of the rare levers that allows you to rent in central Tokyo at prices comparable to the suburbs, with none of the commute penalty.
