When your lease comes up for renewal in Japan, you might get a notice like this:
Starting from the next renewal, the rent will go up by 6,000 yen.
It's a stressful thing to read.
Do you just have to accept it because it's a renewal? If you refuse, will you be kicked out? Will it end up in court? Does the landlord have the upper hand? Or do you, as the tenant?
The short answer: under a standard lease (futsu shakuya), the landlord can't unilaterally lock in a rent increase.
As the tenant, you can say:
At this point I can't agree to a rent increase. Please show me the documents that justify it. I'd like to renew at the current rent.
That said, it doesn't mean you can refuse anything and everything.
Landlords do have a legal route for asking for a rent increase.
What matters is not panicking, but calmly weighing the type of contract, the grounds for the increase, market rents, the cost of the procedure, and the break-even point.
First, Check Whether It's a "Standard Lease" or a "Fixed-Term Lease"
The first thing to look at is the type of contract.
Broadly speaking, building leases in Japan come in two kinds: the standard lease (futsu shakuya) and the fixed-term lease (teiki shakuya).
Standard lease (futsu shakuya)
Most ordinary rental homes are standard leases.
Under a standard lease, the landlord can't easily refuse to renew just because the term has ended.
To refuse renewal, the landlord needs a "justifiable reason" recognized by law.
In other words, the tenant's right to keep living in the home is strongly protected.
The same goes for rent increases: it isn't settled just because the landlord says "we're raising it."
Fixed-term lease (teiki shakuya)
A fixed-term lease is a contract with no renewal.
In principle it simply ends when the term ends.
If you want to stay, it's not a "renewal" but a "new contract."
That makes it easy for the landlord to say, after the term ends:
If you want a new contract, it'll be at the new rent.
This is very different from a standard lease.
With a fixed-term lease, the idea that "I can refuse the increase and keep living here" doesn't work the way it does with a standard lease, so you need to read your contract carefully.
Fixed-Term Leases Have Explanation Requirements
A fixed-term lease isn't valid just because the contract says so in some vague way.
According to the Q&A on fixed-term building leases from Japan's Ministry of Land, Infrastructure, Transport and Tourism, the landlord is expected to explain, in a written document, things such as that the contract has no renewal, that the tenancy ends definitively when the term expires, and the end date of the contract.
The Q&A also says that the explanation of important matters given at signing does not, by itself, count as the advance explanation of a fixed-term lease by the landlord.
So to know whether you really have a fixed-term lease, you need to check not just what the contract says, but also the explanatory document and the procedure that was followed.
Still, for the subject of this article, a landlord saying "we're raising the rent at renewal," the starting point is to confirm:
Is this a standard lease or a fixed-term lease?
Under a Standard Lease, an Increase Isn't Decided Unilaterally
Under a standard lease, the landlord can't simply raise the rent and make it stick.
Article 32 of the Act on Land and Building Leases says that when the rent for a building has become unreasonable, either party may demand an increase or decrease in the rent going forward.
The factors considered include, for example:
- Increases or decreases in taxes and other burdens on the land and building
- Rises or falls in the value of the land and building
- Other changes in economic conditions
- Comparison with rents for similar buildings nearby
In other words, a landlord who asks for more rent needs some kind of reasonable basis.
"It's a renewal, so we're raising it" is a weak argument.
As a tenant, you're entitled to ask for the grounds first.
Your First Move Can Simply Be "No, Please Show Me Your Grounds"
When a rent-increase notice arrives, you don't need to fight back with a long letter.
Keeping your first response very simple is fine.
At this point I can't agree to a rent increase. Please show me the documents that justify it. I'd like to renew at the current rent.
That's enough.
There's no need to be emotional.
The key points are:
- Make it clear that you don't agree
- Ask for the supporting documents
- Show that you intend to keep paying the current rent
Not paying rent is dangerous.
Even if you refuse the increase, you should keep paying the previous rent.
Stopping Your Payments Is Risky
Even if you can't accept the increase, not paying the rent at all is a bad idea.
Unpaid rent becomes a different problem altogether.
Under a standard lease, even if you haven't agreed to the increase, you keep paying the previous rent.
If the landlord refuses to accept it, there are situations where you'd consider "kyotaku," depositing the money with the authorities instead.
The Legal Affairs Bureau also has guidance on depositing money when a landlord refuses to accept rent.
However, a deposit has its own procedures and requirements, so if you actually do it, it's safer to check with a lawyer, a judicial scrivener, the Legal Affairs Bureau, or a consumer affairs center.
If Talks Fail, It Moves to Mediation and Then Court
If the landlord and tenant can't agree on a rent increase, it usually doesn't jump straight to a lawsuit. Mediation comes first.
Article 24-2 of the Civil Conciliation Act says that anyone who wants to bring a lawsuit over a demand to increase or decrease building rent under Article 32 of the Act on Land and Building Leases must first apply for mediation.
This is known as "mediation first."
Roughly, the flow looks like this:
- The landlord notifies you of a rent increase
- The tenant refuses
- Both sides talk, using the supporting documents
- If they can't agree, mediation
- If mediation produces an agreement, it's settled
- If mediation fails, a lawsuit
There's no need to panic at the word "court."
Tenants Face a Risk of Paying the Difference, Too
Pay attention here.
Under Article 32 of the Act on Land and Building Leases, while the two sides haven't reached an agreement, the tenant only has to pay the amount the tenant considers reasonable.
In most cases that means continuing to pay the previous rent.
However, if a court finally rules that the increase was justified, the tenant has to pay the shortfall plus interest at 10% per year.
So this isn't the same as saying:
If I refuse, there's absolutely no risk.
If the landlord's demand is upheld in court, the difference and interest can be charged afterward.
That's why tenants shouldn't get overconfident without any basis either. Check things like nearby market rents, the age of the building, the facilities, rents in the same building, and the history of past rent changes.
Will a Landlord Really Go All the Way to Court?
This is the part people wonder about.
For a 6,000 yen monthly increase, would a landlord really pay for a lawyer and an appraisal and go to court?
My sense is that for a single ordinary home with a 6,000 yen monthly increase, going all the way to court often doesn't make strong economic sense.
Of course, it can't be ruled out.
But looking at the break-even point lets you judge it quite calmly.
Out-of-Pocket Court Fees Are Surprisingly Cheap
First, the revenue stamp fees you pay to the court are very low.
According to the courts' fee table, for a claim of up to 100,000 yen the filing fee for a lawsuit is 1,000 yen, and the filing fee for civil mediation is 500 yen.
For example, if a landlord asks for a 6,000 yen monthly increase, the difference is roughly 72,000 yen a year.
How the value of a mediation matter is calculated depends on the case, but for a small residential rent increase, the stamp fee paid to the court may well be very small.
On top of that, postage stamps and the like cost somewhere from a few thousand yen to about 10,000 yen.
So if someone files for mediation on their own, without a lawyer, the actual court costs can be quite low.
Seen only this way, the bar for a landlord to file for mediation is low.
The Heavy Costs Are Lawyers, Appraisals, and Time
But what's actually heavy isn't the court stamp fee.
What's heavy is:
- Lawyer fees
- Real estate appraisal fees
- Preparing documents
- The time that mediation and court take
- The effort for the management company and the landlord
- The mental cost of a dispute
Rent-increase claims sometimes involve a real estate appraisal.
That's because you need to show an appropriate rent, taking into account nearby market rents, the property's profitability, its location, its age, and how the contract came about.
With lawyer and appraisal fees included, costs can range from several hundred thousand yen to, in some cases, over 1 million yen.
At that point, a 6,000 yen monthly increase on one home takes a long time to pay back.
How to Think About the Break-Even Point
The landlord's break-even point can be roughly estimated with this formula:
Cost of the procedure ÷ (monthly increase × 12 months × number of units affected)
For example, a 6,000 yen monthly increase brings in 72,000 yen more per year for one unit.
If we assume the procedure costs 300,000, 500,000, or 1,000,000 yen, the payback periods look like this:
| Monthly increase | Extra income per year | Payback of 300,000 yen | Payback of 500,000 yen | Payback of 1,000,000 yen |
|---|---|---|---|---|
| 3,000 yen/month | 36,000 yen | about 8.3 years | about 13.9 years | about 27.8 years |
| 6,000 yen/month | 72,000 yen | about 4.2 years | about 6.9 years | about 13.9 years |
| 10,000 yen/month | 120,000 yen | about 2.5 years | about 4.2 years | about 8.3 years |
| 30,000 yen/month | 360,000 yen | about 0.8 years | about 1.4 years | about 2.8 years |
| 50,000 yen/month | 600,000 yen | about 0.5 years | about 0.8 years | about 1.7 years |
Looking at this, bringing in lawyers and appraisers just to raise one unit's rent by 6,000 yen a month is a pretty questionable move.
Even at 300,000 yen, it's about 4.2 years. At 500,000 yen, about 6.9 years. At 1,000,000 yen, about 13.9 years.
Of course, this is simple arithmetic.
But it's very useful for judging whether it makes economic sense.
When a Landlord Gets Serious
So when would a landlord get serious enough to go to mediation or court?
1. When it affects several units
At 6,000 yen a month for one unit, that's 72,000 yen a year.
But for 10 units, it's 720,000 yen a year. For 20 units, 1,440,000 yen a year.
That changes the landlord's economics completely.
Even if it looks like a fight with one tenant, the real goal is sometimes to raise the rent level of the entire building.
2. When rent has been frozen for years and is well below market
The rent hasn't changed in 10, 15, or 20 years.
Compared with nearby market rents and with the rents for new listings in the same building, it has become quite cheap.
In that case, the landlord has a reason to ask for an increase to bring rent back in line with the market.
Article 32 of the Act on Land and Building Leases also lists comparison with rents for similar buildings nearby as a factor in raising or lowering rent.
3. Shops and offices, where the amounts are large
Unlike 6,000 yen a month on a home, shops and offices can see differences of tens of thousands or even hundreds of thousands of yen a month.
A 50,000 yen monthly increase is 600,000 yen a year. A 100,000 yen monthly increase is 1,200,000 yen a year.
In that case, even with lawyer and appraisal fees, it's easier to earn the money back.
4. When it affects the property's value or sale price
For investment properties, annual rent affects the property's value.
For example, even an extra 72,000 yen a year, at a 5% yield, works out in simple terms to roughly 1,440,000 yen of effect on the property's value.
Real valuations are of course more complicated, but from a landlord's perspective, the rent level is tied to selling the property, getting loans, and yield.
So it's not just 6,000 yen a month; it can become a matter of property value, and the landlord gets serious.
5. Corporate landlords, funds, and real estate companies
For an individual landlord, hiring a lawyer and an appraiser for a single unit is a heavy burden.
But a corporate landlord or a real estate company may handle mediation and lawsuits as part of its regular business.
If they have a retained lawyer or in-house know-how, their sense of cost is different from an individual landlord's.
6. Using mediation as negotiating pressure
Even when they have little intention of going all the way to court, a landlord may file for mediation to put pressure on the tenant.
By doing so, the landlord can show a stance of:
We seriously assert that this increase is reasonable.
As a result, even if they don't get the full amount, the two sides may settle somewhere in the middle, like 2,000, 3,000, or 4,000 yen a month.
Risks for the Tenant to Consider
Refusing a rent increase doesn't mean a total win for the tenant, either.
The risks to look at are these.
1. The risk that the increase is eventually upheld
If the landlord's grounds are strong, the increase may be recognized in mediation or in court.
In that case, the shortfall and interest at 10% per year can arise.
2. A worse relationship
Refusing the increase may sour your relationship with the landlord and the management company.
That said, you're exercising a legitimate right, so there's no need to be overly afraid.
3. Moving costs
If you decide that negotiating the rent is too much trouble and move out, you'll face moving costs, upfront costs for a new place, and the hassle.
A 6,000 yen monthly increase is 72,000 yen a year, but moving can cost several hundred thousand yen.
4. With a fixed-term lease, the risk of not getting a new contract
With a fixed-term lease, after the term ends it becomes a question of a new contract.
In that case, your bargaining power is different from under a standard lease.
5. The hassle of deposits and mediation
If the landlord won't accept the previous rent, you'll need to consider depositing it with the authorities.
If it goes to mediation, it takes time and effort.
Documents to Look At in a Rent Negotiation
In a rent negotiation, you look at documents, not feelings.
Here are examples of what you can ask the landlord for.
- Rents for similar properties nearby
- Asking rents in the same building
- The gap with existing rents in the same building
- Increases in property tax and similar costs
- Increases in management fees and repair costs
- Whether equipment was replaced or major repairs were done
- Age of the building
- Condition of the property
- History of past rent revisions
- How the amount of the increase was calculated
As a tenant, it also helps to research nearby market rents yourself.
Compare properties in the same area, of the same age, the same size, with the same facilities, and the same distance to the station.
Saying "nearby rents are going up" isn't enough; you need to compare under similar conditions.
Practical Negotiation Steps
In practice, this order works well.
1. Check the type of contract
Is it a standard lease or a fixed-term lease?
Is it a renewal or a new contract?
Start by confirming this.
2. Check what the increase notice says
- When does the increase start?
- How much is it?
- Are the grounds written down?
- Are the renewal fee and management fee changing too?
- Did it arrive in writing?
3. If you don't agree, say so clearly
At this point I can't agree to a rent increase. Please show me the documents that justify it. I'd like to renew at the current rent.
4. Keep paying the previous rent
Don't stop paying.
If the landlord refuses to accept it, consider depositing it with the authorities.
5. Look at market rents and the grounds
Compare the landlord's documents with the nearby market rents you researched yourself.
6. Consider a compromise
If the landlord's grounds are weak, the rent stays as it is.
If the grounds have some merit, you can also choose to agree on a partial increase instead of the full amount.
For example:
- The landlord asks for +6,000 yen
- The tenant refuses
- You look at the supporting documents
- You agree to +2,000 yen
- Or you agree to talk again in a year
That's one way it can land.
7. If it goes to mediation, rely on documents
In mediation, documents count for more than emotional arguments.
Organize nearby market rents, the contract, past rents, the condition of the facilities, the condition of the property, and the landlord's grounds.
Wording You Can Use
First reply
Thank you for your message. Regarding the rent increase, I can't agree to it at this point. Could you please show me the reasons for the increase and the documents behind how the amount was calculated? For my part, I'd like to renew at the previous rent.
Asking for the supporting documents
To consider the amount of the increase, please share the documents that support it, such as rents for similar properties nearby, rents within the same building, increases in property tax and management fees, and whether any equipment was replaced.
Showing you'll pay the previous rent
Until we reach an agreement on the rent increase, I will pay the previous rent as the appropriate amount.
Offering a compromise
I've reviewed the documents you provided, but at this point I can't agree to the full increase. However, taking into account future rises in management fees and similar costs, I could consider an increase of X yen per month.
Just Saying "No" Is Crude, but the Direction Is Right
You've probably seen the kind of reply that goes viral on social media:
No.
That reply is pretty crude.
But the direction can be right.
That's because under a standard lease, a rent increase isn't decided unilaterally without the tenant's consent.
In practice, though, it's safer to go further and say:
No. Please show me your grounds. I'll keep paying the previous rent.
Just saying "no" looks like an emotional reaction.
Once you add "please show me your grounds," it becomes a conversation about the law and the documents.
Summary: Judge a Rent Increase by the Grounds and the Break-Even Point
When you're told your rent is going up, first, don't panic.
Under a standard lease, the landlord can't unilaterally lock in a rent increase.
Your first move can simply be:
I can't agree. Please give me the supporting documents. I'd like to renew at the previous rent.
That said, with a fixed-term lease it becomes a matter of new-contract terms, so be careful.
Tenants also face the risk of paying the difference.
If the increase is finally upheld, the shortfall plus interest at 10% per year can arise.
Whether a landlord will seriously go to court is easy to understand by looking at the break-even point.
For a single unit with a 6,000 yen monthly increase, once you add lawyer and appraisal fees, it may take years to recover the cost.
On the other hand, if several units, shops or offices, years of frozen rent, a gap from market rents, property value, or a corporate landlord are involved, a landlord can have reason to get serious.
In the end, these are the things to look at:
- Standard lease or fixed-term lease?
- Are there grounds for the increase?
- How does it compare with nearby market rents?
- Does it make economic sense for the landlord to go to court?
- How big is the tenant's risk of paying the difference?
- Is there room to settle on a compromise?
A rent increase isn't decided by who talks loudest, either.
Look at the grounds and the break-even point.
That's the calmest way to handle it.
