When considering real estate investment or rental property management, you have likely come across the term "sublease agreement."
A sublease agreement is an attractive arrangement for property owners, offering stable income and reduced management burden. However, as dispute cases have been increasing in recent years, it is a contract structure that requires careful consideration.
In this article, INA&Associates Co., Ltd. explains the fundamental structure of sublease agreements, their advantages and disadvantages, and key points for avoiding disputes — all in plain language drawing on our real estate expertise.
Whether you are considering a sublease agreement for the first time or are already under contract and thinking about a review, we aim to provide the information you need to make an informed decision.
What Is a Sublease Agreement? Understanding the Basic Structure
Definition of a Sublease Agreement
A sublease agreement is a contract structure in which a property owner (lessor) leases their property in its entirety to a real estate company (sublease company), which then sub-leases the property to tenants (sub-lessees).
This arrangement is also known as a "bulk lease-up" and is built on two independent lease contracts.
The first contract is the "master lease agreement," concluded between the property owner and the sublease company. Under this contract, the sublease company leases the entire building from the property owner.
The second contract is the "sub-lease agreement," entered into between the sublease company and the actual tenant. The tenant pays rent to the sublease company, which in turn pays rent to the property owner.
The Fundamental Difference from a Management Delegation Agreement
To understand sublease agreements, it is important to clearly grasp how they differ from traditional management delegation agreements.
Under a management delegation agreement, the property owner enters into a lease contract directly with the tenant and delegates only the management duties to a real estate company. In this case, the parties to the lease are the property owner and the tenant, with the real estate company acting as a management agent.
Under a sublease agreement, by contrast, the property owner and the tenant have no direct contractual relationship. The sublease company sits in the middle, acting as the lessee toward the property owner and as the lessor toward the tenant.
This structure enables the property owner to receive stable rent from the sublease company regardless of whether the property is occupied.
Legal Status of a Sublease Agreement
From a legal standpoint, the sublease company in a sublease agreement holds the status of "lessee" under the Act on Land and Building Leases (借地借家法) with respect to the property owner.
This is a critically important point: under Article 32 of the Act on Land and Building Leases, the sublease company is granted the right to request a rent reduction.
By virtue of this legal status, the sublease company may request a rent reduction from the property owner on grounds such as changes in economic conditions or the aging deterioration of the property. Similarly, terminating the contract requires just cause, as with ordinary lease agreements.
| Contract Type | Contracting Parties | Rent Payment | Management Responsibility | Vacancy Risk |
|---|---|---|---|---|
| Management Delegation Agreement | Owner ⇔ Tenant | Tenant → Owner | Delegated to management company | Borne by owner |
| Sublease Agreement | Owner ⇔ Sublease Company ⇔ Tenant | Sublease Company → Owner | Sublease company | Borne by sublease company |
How Vacancy Guarantees and Rent Default Guarantees Work
One of the defining features of a sublease agreement is the vacancy guarantee and rent default guarantee.
Under traditional rental property management, a vacancy means a complete loss of rental income, and a tenant's failure to pay rent creates the risk of a difficult recovery process.
Under a sublease agreement, the sublease company guarantees a fixed rent to the property owner. Even if the property sits vacant for a period, or if a tenant defaults on rent, the sublease company continues to pay the property owner in accordance with the contract.
This guarantee allows the property owner to secure stable income.
However, many sublease agreements include an "exemption period." An exemption period refers to a defined span of time — such as from the start of tenant recruitment for a new building until a tenant is secured, or from the departure of one tenant until the next is found — during which the sublease company is relieved of its rent payment obligation.
Before signing any contract, it is essential to confirm whether an exemption period exists and, if so, how long it lasts.
Five Key Benefits of a Sublease Agreement
1. Securing Stable Income
The greatest benefit of a sublease agreement is the ability to secure stable income.
In ordinary rental management, a vacancy immediately cuts off rental income. Under a sublease agreement, however, the property owner receives a fixed rent from the sublease company regardless of occupancy.
This stability is a significant advantage particularly for property owners who are financing their investment with a real estate loan. With fixed monthly loan repayments and equally stable rental income, cash flow becomes more predictable, allowing for reliable financial planning.
Another benefit is reduced direct exposure to rental market fluctuations and economic conditions. Even if vacancy rates rise during an economic downturn, a sublease agreement maintains stable income throughout the contract period, substantially reducing the risks associated with real estate investment.
2. Complete Relief from Rental Management Duties
Under a sublease agreement, all rental management tasks can be entirely entrusted to the sublease company.
Specifically, this includes the following duties:
- Tenant recruitment and screening
- Execution of lease contracts
- Rent collection and reminders
- Responding to tenant inquiries
- Arranging repairs for equipment failures
- Move-out inspections and restoration works
- Contract renewal procedures
Under a management delegation agreement, the property owner must still make the final decisions on repairs and tenant dispute resolution.
Under a sublease agreement, however, since the sublease company contracts directly with tenants as the lessee, all such decisions are also handled by the sublease company.
This complete delegation frees property owners from the day-to-day complexities of rental management, allowing them to focus on their primary business. This convenience is particularly valuable for owners living overseas, elderly owners, and investors with multiple properties.
3. Peace of Mind for First-Time Rental Property Owners
For those with little experience in real estate investment or rental management, a sublease agreement offers a reassuring way to get started.
Rental management involves many tasks that require specialized knowledge and experience — tenant screening, rent setting, and dispute resolution, to name a few.
Under a sublease agreement, all of these specialized duties are handled by an experienced sublease company, allowing even beginners to start rental management with confidence. The absence of direct interaction with tenants also eliminates the stress of handling disputes.
Furthermore, sublease companies have deep familiarity with local rental markets and can set appropriate rent levels and carry out effective tenant recruitment. More efficient and effective rental management can be expected compared to what an individual property owner might achieve on their own.
4. Avoidance of Tenant Disputes
One of the most challenging aspects of rental management is dealing with tenant disputes.
Various issues can arise — rent default, conflicts with neighboring residents, improper use of facilities, and disputes over restoration obligations at move-out.
Under a sublease agreement, since the sublease company is the contracting party with tenants, it handles all such disputes. Property owners have no direct involvement with tenants, significantly reducing their mental burden.
Moreover, because sublease companies manage a large number of properties, they have extensive know-how and experience in dispute resolution. Appropriate handling can be expected even when legal issues arise.
5. Effectiveness as an Inheritance Tax Planning Tool
A sublease agreement can also be an effective measure for inheritance tax planning.
Rental real estate is assessed at a lower value for inheritance tax purposes compared to owner-occupied land, which provides a reduction in inheritance tax liability.
If a sublease agreement enables stable rental management, the property can continue to be assessed as rental real estate up to the time of inheritance. Even if heirs have no experience in rental management, a sublease agreement allows them to take over the inherited property with confidence.
| Benefit | Specific Effect | Particularly Suited For |
|---|---|---|
| Stable income | Avoidance of vacancy and default risk | Loan borrowers, retirees on pension |
| Management delegation | Savings in time and effort | Busy professionals, owners living far from property |
| Beginner-friendly | No specialist knowledge required | First-time real estate investors |
| Dispute avoidance | Reduced mental burden | Those who prioritize stress-free management |
| Inheritance tax planning | Reduction in assessed value | High-asset owners |
Six Key Disadvantages of and Precautions for Sublease Agreements
1. Reduced Profitability Due to High Fees
The greatest disadvantage of a sublease agreement is the high level of fees.
Fees paid to the sublease company are typically set at around 10–20% of rent, which is approximately double the fees under a management delegation agreement (generally around 5–10%).
For example, on a property with a monthly rent of 100,000 yen, a management delegation agreement would cost 5,000–10,000 yen per month in fees, whereas a sublease agreement would incur 10,000–20,000 yen per month. Over the course of a year, this results in a gap of 60,000–120,000 yen.
This fee differential accumulates into a very significant sum over the long term. For investors who prioritize return on investment (ROI), this reduction in profitability is an important factor to weigh.
2. Relinquishing Tenant Selection Rights
Under a sublease agreement, the property owner has no say in selecting tenants.
All tenant screening and selection is carried out by the sublease company. As a result, tenants who do not align with the property owner's preferences may end up occupying the property.
For instance, even if a property was designed for families, the sublease company may decide to operate it as a shared house. There is also the possibility that tenants the owner would prefer to avoid — such as pet owners or smokers — may move in.
This issue can affect the long-term value of the property and relationships with neighbors, and therefore warrants careful consideration.
3. Risk of Periodic Revisions to the Guaranteed Rent Amount
The rent guarantee in a sublease agreement is not permanent.
Most contracts provide for a review of the guaranteed rent amount every two to three years, with the possibility of a reduction based on market rate changes or the aging deterioration of the property.
Since Article 32 of the Act on Land and Building Leases grants the sublease company the right to request a rent reduction, it is difficult for property owners to refuse such requests. In practice, many sublease contracts see guaranteed amounts reduced incrementally at each renewal.
Because these revisions can significantly disrupt the originally projected income plan, it is important to develop a financial plan at the time of signing that adequately accounts for the risk of future reductions.
4. Income Gap Caused by Exemption Periods
Many sublease agreements include an exemption period.
An exemption period refers to a span of time during which the sublease company is relieved of its rent payment obligation, including in the following circumstances:
- From the completion of a new building until a tenant is secured
- From the departure of a tenant until the next tenant is secured
- During major renovation works
Exemption periods are typically one to three months, but may be longer depending on the location and condition of the property. During this period, rental income ceases entirely, which can create difficulties in meeting loan repayments and fixed costs.
5. Continued Obligation to Bear Repair and Renovation Costs
Even under a sublease agreement, the cost of repairs and renovations remains the property owner's responsibility.
All costs necessary to maintain the property — replacing aging equipment, repairing exterior walls and roofs, and renovating interiors — must be paid by the property owner.
These costs tend to increase year after year, particularly for older properties. Some sublease companies require that repair work be carried out by designated contractors, which can result in higher-than-market construction costs.
In addition, sublease companies may charge property owners for renovation work that the company deems necessary to attract tenants. Since these costs are difficult to predict in advance, sufficient financial reserves are essential.
6. Difficulty of Terminating the Contract
A sublease agreement cannot be terminated easily.
Since the sublease company holds the status of lessee under the Act on Land and Building Leases, a unilateral termination by the property owner requires just cause.
Recognized grounds for just cause are limited to the following:
- The property owner needs to use the property themselves
- The building requires demolition and reconstruction due to aging
- The sublease company has breached the contract
In addition to establishing just cause, payment of a surrender premium is typically required in most cases. The amount of the surrender premium is determined by factoring in the equivalent of rent for the remaining contract period and the sublease company's relocation costs, and can be substantial.
| Disadvantage | Impact Level | Mitigation Potential | Owners Who Should Take Note |
|---|---|---|---|
| High fees | High | Compare options before signing | Return-focused investors |
| No tenant selection rights | Medium | Restrictions via contract terms | Owners focused on property value |
| Rent revisions | High | Verify revision conditions | Long-term holders |
| Exemption periods | Medium | Negotiate shorter periods | Loan borrowers |
| Repair cost burden | High | Develop a repair plan | Owners of older properties |
| Difficult termination | High | Verify termination conditions | Short-term holders |
Common Dispute Cases in Sublease Agreements and How to Address Them
1. Rent Reduction Disputes
The most frequently occurring dispute is a rent reduction demand from the sublease company.
There have been numerous cases in which property owners who signed contracts under attractive terms such as "30-year rent guarantee" were later presented with a significant rent reduction demand just a few years into the contract.
A Concrete Example
One property owner entered into a sublease agreement for a newly built apartment block with a guaranteed monthly rent of 800,000 yen. However, at the contract renewal three years later, the sublease company demanded a reduction to 650,000 yen citing "a decline in surrounding market rents," resulting in an annual income decrease of 1,800,000 yen.
Legal Background and How to Respond
Under Article 32 of the Act on Land and Building Leases, the sublease company's right to request a rent reduction is legally recognized. Past court precedents show that in the vast majority of cases where property owners have refused such demands and brought suit, the sublease company has prevailed.
How to respond:
- Thoroughly review the rent revision conditions before signing
- Have the maximum reduction amount explicitly stated in the contract
- Compare the terms offered by multiple sublease companies
- Develop a financial plan that anticipates future reductions
2. Contract Termination Disputes
Disputes in which property owners wish to terminate a sublease agreement but the sublease company refuses are on the rise.
A Concrete Example
An individual who inherited a property and applied to terminate the sublease agreement in order to live in it themselves was refused by the sublease company on the grounds that there was "no just cause," and was further demanded a penalty equivalent to the rent for the remaining contract period (approximately 5,000,000 yen).
Legal Background and How to Respond
Since the sublease company is the lessee under the Act on Land and Building Leases, termination of the contract by the property owner requires both just cause and a surrender premium.
How to respond:
- Clearly define termination conditions at the time of signing
- Confirm the requirements for just cause in advance
- Consult a specialist such as an attorney
- Persistently negotiate for a mutually agreed termination
3. Sublease Company Insolvency Disputes
There have also been cases in which a sublease company's insolvency has caused rent payments to cease.
A Concrete Example
In the "Kabocha no Basha (Cinderella's Carriage)" scandal that came to light in 2018, the collapse of a sublease company left numerous property owners without rental income and struggling to meet their loan repayments.
How to Respond
Preventive measures:
- Investigate the financial condition of the sublease company in advance
- Choose a company that is publicly listed or affiliated with a major corporation
- Spread multiple properties across different sublease companies
Steps to take in the event of insolvency:
- Consider terminating the contract on the grounds of non-payment of rent
- Work toward transitioning to direct contracts with tenants
- Consult an attorney and proceed with the appropriate legal steps
4. Disputes Arising from Inadequate Explanation
Disputes in which property owners did not fully understand the contract terms due to insufficient disclosure of material facts prior to signing are also frequent.
A Concrete Example
There have been cases in which a property owner who understood "rent guarantee" to mean a permanent guarantee only discovered after signing that periodic revisions were in fact part of the contract, and subsequently filed suit claiming that the explanation had been inadequate.
How to Respond
- Review the material disclosure document in detail before signing
- Always ask questions about anything unclear and get a definitive answer
- Confirm everything in writing rather than relying on verbal assurances
- Request a contract review by a third party such as an attorney
5. Repair Cost Disputes
Disputes over the execution of repair works and the apportionment of costs are also common.
A Concrete Example
There was a case in which a sublease company carried out interior renovation work on the grounds that it was "necessary to secure a tenant," then subsequently billed the property owner 2,000,000 yen. The property owner refused to pay, stating that prior consent had not been obtained, resulting in a dispute.
How to Respond
- Clearly specify the consent procedure for repair works in the contract
- Set a cap on construction costs
- Make obtaining quotes from multiple contractors a contractual requirement
- Request regular property condition reports
| Type of Dispute | Frequency | Difficulty of Resolution | Primary Countermeasure |
|---|---|---|---|
| Rent reduction | Very high | High | Review contract terms in detail |
| Termination difficulty | High | Very high | Clarify termination conditions in advance |
| Company insolvency | Low | Very high | Exercise care in company selection |
| Inadequate explanation | Medium | Medium | Third-party review |
| Repair costs | Medium | Medium | Clarify consent procedures |
Conclusion: Key Points for a Successful Sublease Agreement
When used appropriately, a sublease agreement is a highly effective rental management method for property owners. At the same time, it carries numerous risks and disadvantages, making careful consideration and appropriate risk management essential.
Who Is a Good Fit for a Sublease Agreement?
A sublease agreement may be well-suited for those who meet the following criteria:
1. First-time rental property owners
Even without specialist knowledge or experience, entrusting management to a professional sublease company allows you to start rental management with peace of mind.
2. Those with demanding primary occupations
For those who find it difficult to devote time to rental management duties, complete delegation is a significant benefit.
3. Owners of properties in remote locations
When you live far from your property, on-site management becomes a challenge. A sublease agreement resolves the difficulties posed by distance.
4. Those who prioritize stable income
It is well suited for those who are willing to accept some reduction in profitability in exchange for a guaranteed, stable income.
Key Items to Verify Before Signing
When considering a sublease agreement, be sure to confirm the following points:
1. Rent revision conditions
- Frequency of revisions (typically every two to three years)
- Basis for revisions (market rates, property aging, etc.)
- Whether a cap on the reduction amount is included
2. Details of the exemption period
- Length of the exemption period
- Specific conditions under which the exemption period applies
- Cost obligations during the exemption period
3. Termination conditions
- Just cause required for termination
- Required notice period for termination
- Method for calculating penalties and surrender premiums
4. Treatment of repair costs
- Consent procedure for repair works
- Scope and cap on cost obligations
- Rights regarding contractor selection
5. Reliability of the sublease company
- Financial soundness
- History of past disputes
- Management track record and reputation
Next Action Steps
For those considering a sublease agreement, we recommend proceeding through the following steps:
1. Obtain proposals from multiple companies
Gather proposals from at least three sublease companies and compare their terms and conditions.
2. Consult a specialist
Having the contract reviewed by an attorney or tax accountant with expertise in real estate will help minimize risk.
3. Revisit your financial plan
Develop a conservative financial plan that accounts for potential future rent reductions.
4. Periodically review the contract
Even after signing, regularly review the terms and consider negotiating or modifying the contract as needed.
A sublease agreement, when properly understood and appropriately utilized, is an effective means of achieving stable rental management. However, a hasty decision can lead to significant losses.
We strongly recommend conducting thorough due diligence and preparation before entering into any contract that you are fully satisfied with.

Frequently Asked Questions (FAQ)
Q1. Is the rent guarantee in a sublease agreement truly permanent?
A1. No, it is not permanent. Most sublease agreements include a review of the guaranteed rent amount every two to three years.
Under Article 32 of the Act on Land and Building Leases, the sublease company is granted the right to request a rent reduction, meaning the guaranteed amount may be reduced based on changes in market rates or the aging deterioration of the property.
When signing a contract, it is important not to be misled by the phrase "rent guarantee" and to carefully confirm the revision conditions in detail.
Q2. Can a sublease agreement be terminated partway through?
A2. Termination is possible, but very difficult.
Since the sublease company is the lessee under the Act on Land and Building Leases, a unilateral termination by the property owner requires just cause. Recognized grounds are limited to the owner's need to use the property personally, the need to demolish and reconstruct an aging building, and breach of contract by the sublease company.
In most cases, payment of a surrender premium is also required, meaning that termination may involve substantial costs.
Q3. What is the typical fee level for a sublease agreement?
A3. Fees for a sublease agreement are generally around 10–20% of rent.
This is roughly double the fee level of a management delegation agreement (typically around 5–10%). For example, on a property with a monthly rent of 100,000 yen, annual fees would amount to between 120,000 and 240,000 yen.
Since this fee differential accumulates into a significant sum over the long term, those who prioritize profitability should consider it carefully.
Q4. Who bears the cost of repairs and renovations?
A4. As a general rule, repair and renovation costs are borne by the property owner.
All costs necessary to maintain the property — replacing aging equipment, repairing exterior walls and roofs, and renovating interiors — are paid by the property owner. However, damage caused by a tenant's intentional act or negligence may be charged to the tenant.
Before signing, it is important to clearly establish the consent procedure for repair works and the scope of cost obligations.
Q5. What happens if the sublease company goes bankrupt?
A5. If the sublease company goes bankrupt, there is a possibility that rent payments will cease.
In that event, the property owner may terminate the sublease agreement on grounds of non-payment of rent and enter into direct contracts with the tenants. However, transitioning the contracts with tenants can take time, and securing income during that period may prove difficult.
To guard against this risk, it is important to thoroughly investigate the financial condition of the sublease company before signing and to select a company with a solid track record of reliability.
