Japan's rental housing market runs on a dense web of statutes and government guidelines that govern the relationship between an owner (the landlord) and a tenant, as well as the day-to-day management work that sits between them. This article is written for real estate investors, property owners, and management companies, and it gives a comprehensive overview of the main body of law that shapes rental management in Japan. Readers coming from a common-law background should not assume the concepts map neatly onto tenancy law at home -- Japan's framework has its own history and its own balance of landlord and tenant interests, and several of the rules below have no direct equivalent elsewhere.
The sections that follow cover how contract type under the Act on Land and Building Leases changes the rules for renewal and termination, the obligations and liabilities that attach to a lease, the government's guidelines on restoring a unit to its original condition when a tenant moves out, and the legal duties that fall on landlords and management companies -- covering tenant relations, upkeep of building systems, and protection of personal data.
From there, the article turns to housing support for the elderly and other groups who can struggle to find a landlord willing to rent to them, the Housing Safety Net Act, which is aimed at low-income households and other people who need extra support finding a home, and closes with a look at recent amendments and the likely direction of reform, including the effect of digital transformation on the sector.
The Act on Land and Building Leases: Contract Types and the Rules for Renewal and Termination
Residential leases in Japan are governed primarily by the Act on Land and Building Leases (Act No. 90 of 1991), and building leases under that statute come in two broad varieties. One is the ordinary building lease, and the other is the fixed-term building lease. Which type applies has a major effect on the length of the contract, how renewal works, and what it takes to end the tenancy -- and it shapes the rights and obligations of both the owner and the tenant considerably.
- Ordinary building lease (the standard, everyday form of residential tenancy): the contract term is set at one year or longer -- a stated term of under one year is treated by law as a tenancy of no fixed term at all -- and as a general rule the lease renews automatically once its term expires. Two-year terms are the most common pattern in Japanese residential leasing, and the Act on Land and Building Leases sharply restricts a landlord's ability to unilaterally refuse renewal or terminate the tenancy mid-term. Ending the tenancy requires the landlord to show legitimate grounds (under Article 28 of the Act), and the landlord must serve notice of non-renewal during the window that runs from one year to six months before the term is due to expire. Whether grounds are legitimate is decided by weighing a range of circumstances together -- how much the landlord and the tenant each genuinely need to use the building, how long the tenancy has run, whether the landlord has offered a relocation payment, and so on -- and the landlord's own convenience alone is never enough. In practice, a case such as the landlord or a family member needing to move into the unit themselves can count as legitimate grounds, but the tenant's living situation is weighed too, and the decision is made on a fair, case-by-case basis. This is why an ordinary building lease is so protective of the tenant: refusal to renew or termination by the landlord is genuinely difficult to achieve. Even mid-term, a landlord who wants to terminate needs legitimate grounds, while a tenant who wants to end the lease early generally needs only to give the advance notice required by the lease or by the Civil Code, typically one to two months.
- Fixed-term building lease (a lease with a defined term and no right of renewal): the parties agree on a set term in advance, and the lease ends definitively when that term is up. There is no renewal; if the tenant wants to keep living there, the two sides have to sign an entirely new lease. Under a two-year fixed-term lease, for example, the tenancy simply comes to an end after two years, and if both sides want to continue, they negotiate and sign a fresh contract from scratch. For a fixed-term lease to be valid, the law requires the landlord to explain in a document separate from the lease itself that "this is a contract that will not renew and will end when its term expires" (Article 38 of the Act on Land and Building Leases). When the term is one year or longer, the landlord must also notify the tenant that the lease is ending, again during the window from one year to six months before expiry. This notice requirement exists specifically to give the tenant time to prepare for the move and to avoid the tenant being blindsided by a sudden end to the tenancy. Even if the landlord misses that window, giving notice afterward still lets the landlord end the tenancy, effective six months after the notice reaches the tenant. A fixed-term lease can be ended without the "legitimate grounds" test that applies to ordinary leases, but because the tenant is not guaranteed a renewal even if they want one, this type of lease carries more uncertainty for the tenant. For that reason, a fixed-term lease is generally considered less favorable to the tenant than an ordinary one, and landlords sometimes price the rent somewhat lower to offset that disadvantage.
Data from Japan's Ministry of Land, Infrastructure, Transport and Tourism shows that 95.5 percent of leases in Japan's three largest metropolitan areas are ordinary building leases, with fixed-term leases still confined to a comparatively narrow slice of the market. That said, use of fixed-term leases has been edging up in recent years among landlords who have a specific reason to want one back, such as planning to use the property themselves in the future or intending to rebuild it.
In short, the rules for renewal and termination differ significantly depending on which contract type applies under the Act on Land and Building Leases, and an ordinary building lease in particular gives strong, durable protection to the tenant's right to stay housed. Owners need to plan for the long term with the knowledge that they cannot simply end a lease without legitimate grounds. Tenants, conversely, need to understand going in that a fixed-term lease will, as a rule, require them to move out once the term is up, and should weigh that risk carefully before signing. At signing, both sides are well served by confirming exactly which type of lease they are entering into and understanding the rights and duties that come with it.
Obligations Under a Lease: The Duties of the Owner, the Management Company, and the Tenant
A residential lease places legal obligations and liabilities on both the owner (landlord) and the tenant. Where an owner has delegated management to a rental management company, that company also carries significant responsibilities defined by the management contract and by statute. The main duties of each party are as follows.
- The owner's (landlord's) obligations: the landlord must ensure that, for the duration of the lease, the tenant can actually use and enjoy the property as agreed (Civil Code Article 601). In practice, this means handing the property over in a suitable condition and then continuing to carry out any repairs necessary for the tenant's use and enjoyment of the property throughout the tenancy (Civil Code Article 606, paragraph 1). If a problem arises through no fault of the tenant's -- a roof leak or a broken plumbing fixture, for example -- the landlord is required to fix it promptly. Courts have also read into the relationship a duty of care equivalent to that of a good manager in looking after the building, even though no single statute spells this out in so many words. That said, the landlord's repair obligation does not extend to damage caused by the tenant's own intent or negligence (the proviso to Civil Code Article 606). As incidental duties flowing from the lease, the landlord may also be required to keep the tenant's occupancy peaceful, which can include a duty to address interference such as trouble with neighbors, and a duty to maintain building systems and equipment. Once the lease ends and the tenant has vacated, the landlord must also settle and return the security deposit held from the tenant. A security deposit exists to cover unpaid rent and restoration costs, and the balance after those deductions must be returned; a landlord cannot withhold any part of the deposit without a legitimate reason (more on this under the restoration guidelines below). Throughout the tenancy, the landlord must also be careful not to unreasonably infringe on the tenant's rights -- entering the unit without proper justification, or unilaterally cutting off utilities such as water or electricity, can amount to an abuse of the landlord's rights. And when it comes to renewing the lease or changing its terms, the landlord is responsible for following the correct procedure under the Act on Land and Building Leases and other applicable law.
- The tenant's obligations: in exchange for using and benefiting from the property, the tenant is obligated to pay rent on time. Persistent non-payment can lead the landlord to terminate the lease -- whether through the demand-and-termination procedure under Civil Code Article 541 or by exercising a termination right written into the lease -- and can even lead to an eviction lawsuit and, in the worst case, forced eviction, which is why paying rent on time is the tenant's most basic responsibility. The tenant must also use the property in accordance with its agreed purpose and occupy and maintain it with the care of a good manager, an obligation drawn by analogy from the standard of care a fiduciary owes under Civil Code Article 400. In practice, this means honoring the terms of the lease -- not keeping a pet if the lease prohibits it, not disturbing neighbors with noise, and so on. Tenants also carry a duty to restore the property to its original condition when they move out, meaning they are on the hook for repair costs if they cause damage beyond what would occur through ordinary living (discussed in more detail below). If the landlord needs to carry out a necessary repair, the tenant is not permitted to refuse access without good reason (Civil Code Article 606, paragraph 2). Beyond that, tenants are barred from subletting the unit without the landlord's permission and from changing how the property is used without permission; doing either without consent is a breach of contract and can be grounds for termination, whether under the Act on Land and Building Leases or as a general default. A tenant who wants to end the lease early must follow whatever procedure the lease or the law specifies, which usually means giving advance notice of termination within a set number of days or months. And if a lease has a guarantor attached, the tenant also has a responsibility not to create trouble that falls on that guarantor, since if the tenant fails to meet an obligation under the lease, it is the guarantor who ends up covering it instead.
- The management company's obligations (duties of a rental housing management business): when an owner outsources day-to-day rental management to a real estate management company, that company carries out a wide range of tasks under the management contract and under statute. The Act on Proper Management of Rental Housing Business, which took full effect in June 2021 (its formal name translates roughly as the Act on the Proper Management of Rental Housing Business Operations), requires any management company handling a sufficiently large portfolio -- 200 units or more -- to register with the Minister of Land, Infrastructure, Transport and Tourism, and it spells out clearly, for the first time, the duties a registered management company must follow. A management company carries a duty to explain key matters before signing a contract, meaning that before entering into a sublease (master-lease) arrangement or a management-entrustment contract, it must give the owner and the tenant a detailed explanation of the contract's contents, the risks involved, and the services being provided. Companies that run sublease arrangements in particular are barred from exaggerated advertising and improper solicitation, and are required to give owners a clear projection of expected income and expenses. Management companies also carry a duty to keep client funds segregated, meaning that any security deposits, rent, or other money held on an owner's behalf must be kept clearly separate from the company's own assets. Owners are entitled to periodic reporting on how the property is being run -- occupancy, income and expenses, how complaints have been handled, and so on. Each business location must also staff at least one qualified business manager (typically someone holding the certified rental property management qualification), so that a properly trained person oversees the management operation. Management companies also play a major role in dealing directly with tenants: fielding maintenance requests and arranging repairs, handling complaints about neighbors, following up on rent arrears, and attending move-out inspections and settling the security deposit, among many other day-to-day tasks. All of this work has to be carried out within the bounds of the relevant law -- for instance, an aggressive or improper approach to collecting overdue rent could run afoul of the law governing money-lending businesses. Management companies are expected to act fairly and appropriately in order to earn the trust of both the landlord and the tenant, and, as discussed further below, protecting the personal data of tenants and others is also one of a management company's core obligations.
In short, a lease creates a distinct set of rules that the owner, the tenant, and the management company are each expected to follow. The lease document spells out the specifics, but underneath it all sits the Civil Code and the Act on Land and Building Leases. Whether an owner manages a property directly or hires a management company to do it, understanding and following these statutory duties matters. Tenants, for their part, need to be aware not only of their own rights -- the right to demand repairs, the right to renewal, and so on -- but also of their own obligations, including paying rent, exercising reasonable care, and restoring the property at move-out. Sound rental management depends on every party to the lease taking legal compliance seriously.
Guidelines on Restoring a Property to Its Original Condition: Settling the Security Deposit and Allocating Repair Costs
One of the most common flashpoints when a lease ends and a tenant moves out is the question of restoration to original condition and how the security deposit gets settled. "Restoration to original condition" refers to returning the unit to the state it was in when the tenancy began, and disputes over exactly what that requires, and who pays for it, used to be extremely common. To address this, Japan's Ministry of Land, Infrastructure, Transport and Tourism published a set of guidelines titled Guidelines on Disputes and Practice Concerning Restoration to Original Condition, laying out a standard approach to restoration in residential leases (first published in 2004, with a substantially revised edition in 2011). The guidelines are not themselves a law, but they draw on court precedent and the underlying policy of Japan's Consumer Contract Act, and they are widely used as the de facto standard in real-world practice.
The core idea behind the restoration guidelines is to draw a line between "deterioration from ordinary use" and "wear caused by intent, negligence, or use beyond what is ordinary," and to assign the cost of each to a different party. In practice that means:
- Wear and tear from ordinary use and simple aging is not charged to the tenant (it falls on the landlord instead). Ordinary marks and deterioration that build up naturally over the course of daily life -- so-called ordinary wear -- should not be deducted from the tenant's security deposit or otherwise billed to the tenant. The guidelines give specific examples of what counts as "wear the tenant caused through ordinary use": indentations in flooring or tatami mats left by furniture, discoloration on a wall or floor behind a television or refrigerator caused by heat and static, fading of wallpaper or tatami mats from direct sunlight, small pinholes left by thumbtacks used to hang posters, and equipment that simply reaches the end of its service life and breaks down. None of these results from any fault on the tenant's part -- they are an unavoidable part of living in a home -- so the guidelines hold that the landlord, not the tenant, should bear the cost of fixing them. Fading wallpaper or tatami in a sun-facing room, for instance, is simply unavoidable, so billing the tenant unilaterally for replacing it is considered an excessive burden.
Discoloration in tatami mats or marks left by furniture that build up during the ordinary course of living are treated as ordinary wear, and the tenant carries no restoration obligation for them. Absent a clear, specific agreement to the contrary, the guidelines hold that this kind of everyday wear and minor damage that comes from simply living in the space falls on the landlord, and should not be deducted from the deposit.
- Damage or deterioration caused by intent, negligence, a breach of the tenant's duty of reasonable care, or use beyond what is ordinary is charged to the tenant. Where damage results from the tenant's own carelessness or fault, or from use that clearly goes beyond normal, everyday use, the guidelines hold that the tenant should cover the repair cost. Examples given include walls and ceilings stained by tobacco smoke and odor, walls riddled with holes (a single thumbtack hole counts as ordinary wear, but numerous or large holes can be judged as negligence), a carpet stained throughout from spilled drinks, damage a pet has done to a post or a sliding door (even where pets are allowed, the extent of the damage matters), unauthorized renovation or painting done without permission, and mold or rot the tenant caused through neglect, such as mold that grows because the tenant failed to ventilate the room. In cases like these, the tenant is considered to have breached the duty of reasonable care or to have been negligent, and it is considered appropriate to deduct the repair cost from the deposit, or to bill the tenant separately if the deposit does not cover it. The guidelines define restoration as "returning the property from wear or damage caused by the tenant's intent, negligence, or use beyond what is ordinary" -- which, read the other way, explicitly excludes the cost of repairing ordinary wear.
Building on that basic principle, the guidelines set out how to allocate cost across a wide range of specific situations. For soiled wallpaper, for example, they hold that charging the tenant for a full repapering once the wallpaper's useful life has already elapsed goes too far, and that the tenant's responsibility should be limited to repairing the soiled section itself. For tatami mats, the guidelines note that the value of a tatami surface is generally considered to depreciate to zero over six years, so charging the tenant for the cost of replacement after long years of use is likewise inappropriate. The guidelines also address special clauses that shift cost onto the tenant, noting that such a clause must clearly spell out the scope of what the tenant is responsible for, and the tenant must genuinely understand and agree to it. A clause along the lines of "the tenant is responsible for a professional cleaning fee of [a stated amount]" can be valid, but only if the landlord clearly explained it and the tenant knowingly agreed to it at signing. Japan's Consumer Contract Act can void a clause that is one-sidedly disadvantageous to the consumer -- here, the tenant -- so there are limits to what a special clause can achieve; courts have in fact struck down clauses that tried to push the cost of ordinary wear onto the tenant.
What matters most when settling a security deposit is that the landlord or management company base the settlement on solid, documented evidence. Photographing and recording the condition of a unit at move-in, and then comparing that record against the condition at move-out, goes a long way toward preventing disputes. Some management companies use a move-in and move-out checklist that both sides confirm together. Tenants, for their part, are well served by inspecting the unit themselves before moving out and forming their own view of what is ordinary wear versus damage they are responsible for. If a tenant is genuinely unhappy with how a deposit was settled, discussing it with reference to the guidelines is the first step, and if the two sides still cannot agree, a local consumer affairs center or dispute resolution body is available to help. The full, revised edition of the guidelines runs to 173 pages, but landlords and tenants who grasp just the basic principles can head off most disputes before they start.
To sum up, the restoration guidelines have established a clear working principle: ordinary wear is the landlord's cost, and damage from fault or negligence is the tenant's. The security deposit exists to cover those costs, but a landlord is never entitled to deduct costs from it that should properly fall on the landlord instead. For owners and management companies, settling deposits fairly and in line with the guidelines is essential to maintaining trust with tenants, and tenants likewise benefit from understanding, both when they sign and when they move out, exactly what they will and will not be responsible for.
Legal Duties of Landlords and Management Companies: Tenant Relations, Building Systems, and Personal Data Protection
Running a rental property comes with a wide range of duties for the landlord (owner) and any management company involved, arising from both the lease itself and from statute. That responsibility spans tenant relations, the upkeep of a building's physical systems, and even protecting the privacy of tenants and other individuals. This section lays out the main legal duties that fall on landlords and management companies.
- Duty to respond to tenants (as the landlord's responsibility): a landlord is obligated to respond appropriately so tenants can live with peace of mind. If a tenant requests a repair, for example, the landlord must act on it promptly (this is the repair obligation under Civil Code Article 606 discussed earlier), and complaints about noise or a water leak require the landlord to investigate the cause and take whatever steps are necessary. A landlord who is notified of a broken fixture and simply ignores it risks the tenant demanding a rent reduction or damages (Civil Code Article 611 provides for a rent reduction where part of the leased property becomes unusable). Landlords are also bound by a general duty of good faith to respond sincerely to tenant inquiries and requests. Even where management has been outsourced to a company, ultimate responsibility still rests with the owner. The management company, standing in for the owner on the front line of tenant relations, is expected to provide services such as round-the-clock emergency response -- a burst pipe at night, for instance -- and to serve as the point of contact for tenant complaints. How well a management company handles this work has a direct effect on tenant satisfaction and on the property's reputation, so responding to tenants quickly and professionally really matters. In recent years, unreasonable demands directed at management companies by difficult tenants -- a form of customer harassment -- have also become a recognized problem, but either way, the expectation is that both sides respond within the bounds of what the law and the lease actually require.
- Duty to maintain the building and its systems: as the owner of the building, the landlord is obligated to keep its physical systems in a lawful and safe condition. Concretely, this means inspecting and maintaining equipment in line with laws such as the Building Standards Act and the Fire Service Act -- annual inspection of fire safety equipment and fire-prevention management, for example -- and repairing deterioration as it appears. Periodic inspection of elevators, water and drainage pumps, and similar equipment is typically outsourced to specialist contractors. For the kind of equipment failure that comes up constantly in rental housing -- a broken water heater, a malfunctioning air conditioner, a clogged drain -- the default rule is that the landlord pays for the repair unless the tenant caused the problem through intent or negligence. Because equipment such as air conditioning and hot water is part of the basic infrastructure of daily life, leaving a failure unaddressed can seriously disrupt a tenant's living situation, so a prompt response is essential. If a landlord neglects this duty, the law even allows a tenant to pay for the repair out of pocket and then bill the landlord for it (Civil Code Article 608, covering a tenant's right to be reimbursed for expenses when the landlord fails to meet an obligation). Regular building cleaning, pest control, and management of common areas -- lighting in the entrance and hallways, for example -- also fall within the landlord's area of responsibility. Where this work is entrusted to a management company, the management contract should spell out the scope of the work clearly, and the company should be required to report on what it has actually done. The Act on Proper Management of Rental Housing Business has made an owner's right to periodic reporting from the management company an explicit statutory requirement. This is meant to make a property's maintenance status and financial condition more transparent and to reduce the risk of a property being neglected -- in other words, the law itself now imposes a reporting and explanation duty toward the owner, making it easier for an owner to stay informed about how a property is actually being managed. Owners themselves are also expected to check on the status of legally required inspections and to take an active role -- budgeting for repairs and drawing up a maintenance plan as needed, rather than leaving everything to the management company.
- Duty to protect personal data: rental management work involves handling a large volume of personal data -- move-in applications, lease agreements, certificates of residence, guarantor information, and more. Whether the landlord handles this directly or a management company does, both are obligated to comply with Japan's Act on the Protection of Personal Information (Act No. 57 of 2003) and related regulations. Because a management company in particular accumulates the personal data of a large and constantly changing pool of tenants, it carries a legal responsibility, as a business handling personal information, to put proper security measures in place. In practice, that means clearly stating the purpose for which personal information is being collected -- a tenant's or owner's name, address, contact details, employer, and so on -- and obtaining it through lawful, fair means. Information that has been collected must then be stored securely, protected by security controls such as access restriction and encryption, to prevent unauthorized access or a data leak. Companies are also obligated to respond promptly, through the legally required process, to a request from an individual to disclose, correct, or stop using their own data. Sharing personal data with a third party without consent is prohibited as a general rule (under, among other provisions, Article 27 of the Act on the Protection of Personal Information), and where sharing is genuinely necessary, the company needs to confirm that it has the individual's consent or that a specific statutory exception applies. Passing a tenant's information to a rent-guarantee company, for example, or handing an overdue tenant's information to a collection agency, requires following the correct procedure, whether through a consent clause in the lease or under a specific provision of law. As lease paperwork increasingly moves online and management shifts to the cloud, cybersecurity has become correspondingly more important. If a data breach does occur, the management company or landlord carries a responsibility to notify the affected individuals promptly and to explain the scope of the impact and the steps being taken to prevent a recurrence. A 2022 amendment to the Act on the Protection of Personal Information strengthened the duty to report and notify in the event of a breach, and a breach above a certain scale must now be reported to Japan's Personal Information Protection Commission. Sector-specific guidelines on personal information in rental management have also been published, and management companies are expected to build out proper internal structures through staff training and internal rules. In short, protecting tenant privacy is both a legal obligation and part of the foundation of a trustworthy rental business. Mishandling personal information can escalate into litigation or regulatory action, so landlords and management companies need to treat it with real care.
As this section has laid out, landlords and management companies carry a multi-layered set of legal duties spanning tenant relations, building maintenance, and data protection. Renting out property is not simply a matter of handing over the keys -- it functions, in effect, as a service business, and balancing legal compliance with tenant satisfaction is essential. The Act on Proper Management of Rental Housing Business has strengthened governance across the industry in recent years, and low-quality management and neglectful practices are gradually being corrected as a result. Owners need to entrust their properties to a reliable management company while also understanding their own basic legal duties. From a tenant's perspective, a well-managed property is one they can live in comfortably for the long term, which in turn makes an owner's rental business more stable as well. Meeting these legal duties is not just about avoiding disputes -- it is the foundation that a smoothly run rental business is built on.
The Housing Safety Net Act: Support for Elderly, Foreign, and Low-Income Tenants
As Japan's population ages and income inequality widens, growing attention has turned to people who face particular difficulty securing housing. The elderly, people with disabilities, foreign residents, low-income households, families raising children, and disaster survivors -- people in these groups who struggle to find housing in the private rental market are referred to collectively as housing-vulnerable individuals. The Housing Safety Net Act (whose formal name translates roughly as the Act on the Registration and Promotion of Rental Housing that Accommodates Housing-Vulnerable Individuals) was enacted specifically to support this group in finding housing.
An overview of the Housing Safety Net Act: this law, which took effect in 2017, sets up a system aimed at increasing the supply of rental housing that housing-vulnerable individuals can move into with peace of mind. Concretely, it creates a mechanism through which a landlord can register their property with the local government as housing that will accept vulnerable tenants. Registered properties are listed in a public database maintained by the prefecture or another local authority, so that information reaches the elderly and others who need housing. A range of support measures also kick in once a vulnerable tenant moves into a registered property: subsidies toward renovation costs for accessibility work such as removing steps or installing handrails, subsidies to make up the difference where a landlord sets rent below market rate, and subsidized rent-guarantee insurance premiums for landlords who use a private rent-guarantee company, all delivered through a joint framework between the national government and local authorities. On top of that, regionally based housing support councils and nonprofit housing support organizations have been set up to match prospective tenants with willing landlords, to check in on tenants after they move in, and to provide broader support during the tenancy.
The backdrop to all of this is a longstanding social problem: landlords refusing to rent to elderly applicants. Landlords have generally tended to shy away from renting to this group out of concerns such as how to handle it if an elderly tenant living alone dies unnoticed in the unit, how to manage the language and cultural gap with a foreign tenant, or the risk that a tenant on public assistance will fall behind on rent. Ministry of Land, Infrastructure, Transport and Tourism data indeed shows that roughly one in five landlords has experienced refusing to rent to an elderly applicant at some point. The Housing Safety Net Act is designed to ease these anxieties on both the landlord's and the tenant's side, with the aim of securing "a place to live that anyone can feel secure in."
The Housing Safety Net system rests on three main pillars:
- A registration system for safety-net housing: a mechanism for registering, with the local government, private rental properties whose landlords will not turn away housing-vulnerable applicants, and then publicizing those properties. Registration comes with certain requirements around building equipment, accessibility standards, and rent level. Registered properties carry a distinguishing mark that makes them easier for prospective tenants to find.
- Financial support measures: a system under which registered properties can receive support from the national government and local authorities for renovation costs, rent reductions, and guarantee-fee subsidies, among other things. For example, where a landlord renovates a floor plan to suit a family with children, or sets rent below the going market rate for a household on public assistance, the government can subsidize part of the resulting cost or shortfall, easing the burden on the owner.
- Promoting housing support activities: expanding support provided by welfare professionals and nonprofit organizations, covering softer, human-centered work such as checking in on tenants after move-in and helping resolve problems that come up. Housing support organizations also confirm vulnerable tenants' well-being, provide life counseling, and even help clear out belongings left behind after a move-out, all of which reduces the risk landlords face.
Thanks to this system, it has become somewhat easier, for example, for an elderly person living alone to find a rental unit, and the environment has gradually improved so that landlords can offer housing to this group while receiving support of their own. The number of registered properties grew slowly at first after the law took effect, but has been picking up gradually in more recent years. A further amendment is planned for 2025 (discussed below), aimed at strengthening the support measures and encouraging wider use of the system.
The 2025 amendment to the Housing Safety Net Act: the government passed an amendment to the Act during its ordinary session of the Diet in 2024, and it is scheduled to take effect on October 1, 2025. The amendment centers on three main points.
- Point 1: building a market environment where both landlords and vulnerable tenants can feel secure -- to encourage smoother matching and sound leases, a public certification system for rent-guarantee companies will be introduced. The government will certify guarantee companies that meet a set of standards, so landlords worried about the risk of unpaid rent from a vulnerable tenant can use a certified company with confidence. This point also includes preparing guidelines for handling situations such as a tenant dying alone in the unit, and encouraging the development of relevant insurance products.
- Point 2: strengthening in-tenancy support through housing support organizations and similar bodies -- to let housing support organizations play a more active role in checking on tenants and providing life support after move-in, the amendment formally establishes new tasks such as clearing out belongings left behind, along with funding support for that work, and strengthens coordination with welfare services. This should mean public support becomes available for situations a landlord could never realistically manage alone -- clearing out a unit after an elderly tenant has died, for instance, or responding to problems that arise as a tenant's dementia progresses.
- Point 3: closer coordination between housing policy and welfare policy -- housing authorities and welfare authorities in each region will coordinate more closely, consolidating consultation points for supporting vulnerable individuals and building out a local support network, including systems for checking in on tenants. This should make it easier to spot and resolve problems at the ground level, helping tenants stay housed in safety-net properties over the long term.
Preparations for the certified guarantee-company system and related measures are expected to begin around the summer of 2025, ahead of the amended Act taking effect. Moves like this speak to an urgent challenge for a country facing a rapidly aging society: expanding the housing safety net. For rental property owners, this also opens up a new option for renting to groups they may previously have avoided, potentially turning what was once seen as a difficulty into an asset in filling vacancies. A landlord might, for example, use the available subsidies to renovate a unit for accessibility and then run it as a stable, purpose-built rental for elderly tenants -- one of several strategies this system makes more viable.
That said, limited public awareness of the system and landlords' own psychological hesitation remain real obstacles. Realistic anxieties -- the risk associated with an elderly tenant living alone, or the risk of arrears from a tenant in financial difficulty -- have not been fully resolved. As a result, the government continues to work on both the "soft" and "hard" sides of the problem, expanding public guarantees and strengthening check-in services, in order to bridge the gap between landlords who are willing to rent and vulnerable individuals who need housing. The Housing Safety Net Act sits at the intersection of social welfare and real estate leasing and is an important piece of law that will likely keep evolving as circumstances change. Owners and management companies would do well to keep an eye on developments in this area and consider whether any of the available support measures could be put to use in how they run their own properties.
Recent Legal Reforms and What Comes Next: Tightening Regulation and the Impact of Digital Transformation
The regulatory landscape around Japan's rental housing business has been shifting substantially in recent years. Updates are underway on multiple fronts at once: stronger tenant protection, tighter industry standards, and adaptation to digital transformation (DX). This final section reviews the major recent legal reforms and where the field appears to be heading.
- The 2020 Civil Code reform and its effect on lease rules: a sweeping reform of the obligations section of Japan's Civil Code took effect on April 1, 2020, and it brought several important changes affecting real estate leases. One of the most significant is that setting a maximum guarantee amount is now mandatory for an individual guarantor's contract. Where an individual agrees to serve as a joint guarantor on a lease, the guarantee contract itself is now void unless it specifies a maximum liability amount -- a cap on how much the guarantor could ever be on the hook for. A lease now has to state something along the lines of, "the guarantor jointly guarantees all debts owed by the tenant, provided that the maximum guaranteed amount shall be [a stated sum]." This protects the guarantor -- effectively a form of tenant-side protection -- from open-ended liability and from being saddled with an unexpectedly large debt. The revised Civil Code also codified, for the first time in statute, the definition of a security deposit and the rules for returning it: a security deposit is now defined in law as money held to secure the tenant's obligations, to be returned at the end of the lease after deducting unpaid rent and restoration costs, formalizing a rule that had previously existed only through case law. The reform also tidied up and reinforced several other rules relevant to leases -- a tenant's right to a rent reduction where part of the leased property is destroyed or becomes unusable, a tenant's own right to carry out repairs under Article 606, paragraph 2, and a tenant's right to be reimbursed for expenses under Article 608. As a result of these changes, standard lease templates needed to be revised, and landlords in particular need to be careful not to omit the maximum guarantee amount whenever a lease includes a guarantor. Because the revised Civil Code sits alongside the Act on Land and Building Leases as one of the two pillars of basic lease law, owners and management companies need to understand the changes correctly and build them into everyday contracting practice.
- Full implementation of the Act on Proper Management of Rental Housing Business (2021) and its effect on industry standards: as discussed earlier, the Act on Proper Management of Rental Housing Business took effect in June 2021 and tightened regulation of the rental management business considerably. In response, many management companies registered with the Ministry of Land, Infrastructure, Transport and Tourism and took steps such as staffing a certified rental property management professional and tightening up how they explain key contract terms. The law bars exaggerated advertising by sublease operators and requires them to explain contracts before signing, and it imposes a duty of segregated fund management and a duty of periodic reporting on every company that accepts a management-entrustment contract -- all aimed at pushing bad actors out of the market and raising overall service quality. The first enforcement actions under the law appeared in 2022, including a business-suspension order issued against an unregistered operator carrying out management work, showing that the regime is being enforced in practice, not just on paper. Compliance awareness among management companies is likely to keep rising under this regime, and reliable, trustworthy management services should become more firmly established for the benefit of both owners and tenants. Owners, for their part, should check whether a prospective management company is properly registered and whether it has a certified rental property management professional on staff. Entrusting a property to a company that holds the correct license and registration reduces the risk of a legal violation and helps prevent contract disputes before they start.
- Reform of the Building Lots and Buildings Transaction Business Act and the digital transformation of real estate transactions (2022): digitalization has been reshaping how both rental and sale transactions get done. Historically, real estate transactions required an in-person explanation of key contract terms (Article 35 of the Building Lots and Buildings Transaction Business Act) and delivery of a paper contract and disclosure documents (Article 37 of the same Act). Regulatory easing changed that: starting in 2019, rental transactions were permitted to deliver the key-terms explanation online via video conferencing, and a further amendment to the Act in May 2022 made it possible to deliver contract documents electronically as well. This means a lease and its key-terms disclosure can now be provided as an electronic file, such as a PDF, rather than on paper, and a physical seal or signature is no longer required. In practice, this makes a fully remote, paperless transaction possible: the key-terms explanation happens online, and afterward an electronically signed contract is exchanged by email or a similar channel. The Ministry of Land, Infrastructure, Transport and Tourism has also published guidelines on conducting the online key-terms explanation and electronic contracting safely. This shift toward electronic contracting for real estate transactions brings real efficiency gains to rental management. An owner or tenant living far away no longer needs to visit an office in person to complete a lease, which shortens the time it takes to finalize a contract, saves the stamp duty that a paper contract would otherwise attract (electronic contracts are exempt from Japan's stamp tax), and cuts the cost of storing paper documents. On the other hand, this shift also brings new challenges, such as supporting users who are unfamiliar with electronic contracting and tightening identity verification to prevent impersonation. Electronic contracting services and digital signatures are likely to keep spreading in the leasing field going forward, further accelerating the digital transformation of the contracting process. Owners and management companies should choose a reliable electronic contracting platform and put internal rules in place to support it properly.
- Where things go from here: balancing tenant protection with operational efficiency: the direction rental management takes from here will likely hinge on how well the industry can balance further strengthening tenant protection with keeping the business side stable for owners. On the legal front, the trend toward supporting housing access for socially vulnerable groups, exemplified by the Housing Safety Net Act reform discussed above, looks set to continue, even as policymakers also debate measures to support owners on issues such as vacant and aging housing stock. In leasing as well, electronic contracting and Internet-of-Things technology are advancing, with smart locks for key management, online property viewings, and AI-assisted tenant screening all beginning to change how the business is actually run day to day. Regulators, too, have been actively promoting real estate technology, and the push to streamline what has historically been a paperwork-heavy business shows no sign of reversing. On top of that, remote work and shifting lifestyles since the pandemic have diversified what tenants are actually looking for. New leasing formats are emerging as a result, including short-term rentals built around fixed-term leases, furnished serviced apartments, and arrangements that resemble short-stay lodging. That said, the more novel the leasing arrangement, the more carefully it needs to be checked against existing regulation -- short-stay lodging, for example, is subject to the Hotel Business Act and to local ordinances, and using a fixed-term lease carelessly can easily create disputes with tenants. Owners and management companies experimenting with a new business model should thoroughly check the relevant law in advance and, where needed, bring in expert advice.
Taken as a whole, Japan's rental housing market is clearly at a turning point. Demographic change, technological innovation, and legal reform are combining to make old assumptions less and less reliable. In this environment, what matters most is staying current on the latest regulatory developments and putting that knowledge into practice. The Act on Land and Building Leases, the restoration guidelines, the Act on Proper Management of Rental Housing Business, and the Housing Safety Net Act, all covered in this article, are essential knowledge for anyone in the business. It is also worth watching for amendments still to come into force, such as the 2025 reform of the Housing Safety Net Act discussed above, and for the possibility of future revisions to the Civil Code and the Act on Land and Building Leases themselves -- reform of the renewal system, or a new kind of guarantee arrangement, are among the ideas that could plausibly come up for debate down the road.
Rental property management sits at the intersection of law and day-to-day practice, and the two are tightly interwoven. Running a rental business without understanding the relevant law risks exposure to problems an owner never saw coming, while understanding the law properly opens up both risk management and genuine business opportunity. Owners and management companies are encouraged to use the material in this article to review their lease documents, improve their management procedures, and inform their strategy going forward. Complying with the applicable regulations while adapting to how the industry is changing is how a rental business achieves both a stable, healthy return and a reputation as a landlord that tenants actively want to rent from.
