Japan's single-person elderly households continue to grow year by year. As of 2020, over 7 million people aged 65 and older live alone (according to the Statistics Bureau of the Ministry of Internal Affairs and Communications' National Census). Against this backdrop, "unattended deaths"—where rental housing residents pass away without anyone present to attend them—have become increasingly common.

When an unattended death occurs, landlords, heirs, and property management companies face not only emotional distress but also financial and legal challenges. While it may seem like a topic unrelated to you, if you rent, it is knowledge worth understanding to prepare for unexpected circumstances.
The first issue that arises when an unattended death is discovered is the disposal of furnishings and personal belongings left in the unit—the so-called "leftover belongings."
When heirs exist
The deceased's legal heirs inherit ownership of the leftover belongings, so heirs are responsible in principle for removal and disposal. However, if heirs renounce inheritance, ownership becomes unclear. The landlord can petition the family court to appoint a "successor administrator" to handle the matter, though this process can take several months.
When heirs are absent or cannot be located
If heirs do not exist or cannot be reached, the landlord cannot dispose of the belongings arbitrarily. Disposal without legal proceedings risks being classified as "unlawful conduct." The "Model Contract Provisions on Handling Leftover Belongings" published by the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Justice in 2021 provides guidance on addressing such situations. Under these provisions, you can establish a contract that grants authority to a designated agent (such as a guarantor or legal professional) to handle leftover belongings disposal, enabling smooth resolution.
Role of guarantor companies
Guarantor companies primarily address rent defaults, but in recent years some have introduced "unattended death response provisions." Plans that cover part of the cost of property removal and restoration are now available. It is worthwhile to review the coverage details at the time of contract signing.
Typical restoration costs
Special cleaning (disinfection and deodorization) plus leftover belongings disposal can cost 2 million to 5 million yen even for a 1K unit, with costs rising significantly if the body goes undiscovered for an extended period. To cover such risks, utilizing "unattended death insurance" (discussed below) becomes essential.
Whether a property where an unattended death occurs is classified as an "affected property" requiring disclosure is a matter of significant interest to tenants.
In October 2021, the Ministry of Land, Infrastructure, Transport and Tourism established the "Guidelines on Death Disclosure by Real Estate Agents" to provide industry standards. Key points include:
While these guidelines are industry self-standards rather than law, real estate agents are expected to comply. A common interpretation emerged that "after 3 years, disclosure is not required," but in practice, disclosure may be necessary depending on the property's circumstances and specific tenant inquiries. If you have questions, we recommend confirming directly with the real estate agent.
In recent years, against the backdrop of increasing single-person and aging households, insurance products called "unattended death insurance" have proliferated. These generally fall into two categories: landlord-focused and tenant-focused (occupant-focused).
Landlord-focused unattended death insurance
This type is purchased by rental property owners or management companies and covers restoration costs, leftover belongings removal fees, and lost rent when an unattended death occurs. Policies are typically underwritten per property or per unit and can be purchased for monthly premiums of several hundred to several thousand yen.
Tenant-focused (occupant-focused) unattended death insurance
This type is purchased by the occupant or their family and covers expenses borne by heirs in case of death—such as special cleaning and restoration—and some plans include death benefits. Some existing fire insurance or household goods insurance policies allow attachment of unattended death provisions, so review your current coverage.
Some municipalities subsidize insurance premiums as part of their unattended death prevention initiatives for elderly single-person households. It is worth inquiring at your municipal government's welfare department.
You can also research whether a property has a history of accidents by taking initiative during the property search phase.
Property Search Site Disclosure Filters
Real estate information sites like "LIFULL HOME'S" offer filtering features to identify properties with "disclosure matters." Disclosure matters include not only accident properties but various other circumstances; however, these tools help you consciously identify and exclude properties that may be affected properties.
Accident Property Information Sites
Private accident property information sites (such as "Ooshima Teru") publish user-submitted information about past unattended deaths, suicides, and accidents. However, information accuracy and completeness have limitations, so use these as reference material only.
Checklist for Viewings and Before Signing
Delayed discovery is the primary factor that amplifies the secondary harm of unattended death. Monitoring systems to prevent isolation among elderly residents and single-person households can be implemented even in rental housing.
Municipal and NPO welfare check services
Many municipalities provide regular in-person welfare visits or telephone check-in services for elderly residents living alone. Services are typically free or low-cost and can be arranged through your municipal community health center or elderly welfare department.
IoT and smart device applications
What residents and landlords can do
For occupants at higher risk of unattended death (elderly singles, those with underlying health conditions, etc.), regular patrol visits and courtesy calls from landlords and management companies can effectively prevent discovery delays. Residents themselves can also take the most basic and effective prevention measure: maintaining regular communication with family, friends, and neighbors.
Unattended death is not merely an "issue for the elderly"—it is a topic that affects everyone living alone in rental housing. Knowledge and awareness are the greatest risk mitigation strategies for both renters and landlords.
