Rent Increase in Japan 2026: Your Landlord Cannot Decide Alone

Q: I was asked to sign a rent increase notice.

Do not sign it on the spot, since signing is treated as agreement. Say you need to check the details first, then review your contract and where to get advice.

Q: Does a fixed-term lease work differently?

Yes, a fixed-term lease ends at a set date and terms can change when you sign a new contract. If it has a clause on how the rent is revised, the Article 32 rule that lets you pay what you consider fair until a court decides does not apply (Article 38(9)). Check your own contract to see which type you have.

Figures, prices and terms were checked against Articles 26, 28 and 32 of the Act on Land and Building Leases and Article 24-2 of the Civil Conciliation Act on 30 October 2026. They change — check the current terms yourself before you sign up or file anything.

In short

Your landlord cannot raise your rent unilaterally. If the two of you cannot agree, you first go to mediation at the summary court, and only then to a lawsuit (Civil Conciliation Act, Art. 24-2).
You are strongly protected by the Act on Land and Building Leases. Saying no does not get you evicted.
If you do not agree, paying your current rent is enough until a court decides. But if the court rules the increase is justified, you pay the shortfall plus 10% interest a year.
Three things matter most: do not sign anything on the spot, check your contract, and keep a record of every exchange.
The same goes for an increase at renewal. Without notice, the lease renews on the current terms, and the landlord needs justifiable grounds to refuse renewal.
That said, if the reason is reasonable and cheaper than moving, accepting it can be the smart choice. The decision is yours.

Knowing this, when the rent-increase letter arrives you sign nothing in a panic – because you know your current rent is enough until the matter is settled.

Bottom line first: your landlord cannot decide a rent increase alone

Many students worry about the same two things. The landlord suddenly says the rent is going up. Saying no feels like it could get you kicked out. You can relax: in Japan, tenants are protected by strong, specific law.

Under the standard fixed-term-free lease (futsu shakka keiyaku) that most renters have, changing the rent starts with a discussion with your landlord. Your landlord may announce a higher rent. If you tell them you do not agree, the increase is not settled on the spot. If you still cannot agree, it goes to court mediation first, then to a lawsuit.

A landlord cannot raise the rent alone. The landlord says the rent is going up; you, the tenant, say you do not agree. The increase is not decided by one side; if you cannot agree, it goes to mediation first, then to court. Until it is settled, your current rent is enough; if a court confirms the increase, you pay the gap plus 10% a year.

The law behind this is the Act on Land and Building Leases (shakuchi shakka ho). Under Article 32, if you and the landlord cannot agree, you only have to pay what you consider a fair amount until a court rules that the increase is justified. Usually that is your current rent. But if the court confirms the increase, you must pay the shortfall plus interest of 10% a year. Landlords do sometimes win these cases, so your current rent is not guaranteed forever.

Why rent increases are becoming more common

Rents are climbing across Japan. The drivers include:

Rising land prices and property taxes: landlords face higher holding costs (land prices: Ministry of Land, Infrastructure, Transport and Tourism, 2026 official land prices, in Japanese)
Higher construction and labor costs: new-build rents go up, and existing units follow
Demand in major cities: vacancies are shrinking in places like Tokyo and Osaka, pushing rents higher

Cause-and-effect diagram of why rent increases are rising: land prices and property tax raise landlords' holding costs, construction and labor costs push up new-build rents and existing units follow, and demand in big cities shrinks vacancies in places like Tokyo and Osaka. Together they mean more rent increase notices, which is why it matters to know an increase is not decided by one side

In other words, rent increase notices are only going to become more common. That is exactly why knowing that an increase is not decided by one side matters.

5 steps for when a rent increase notice arrives

Your landlord hands you a notice saying the rent is going up, and you sign it there and then. Where you come from, a tenant may simply have to accept whatever rent the landlord sets. In Japan, the landlord cannot set a new rent alone, and your signature is treated as agreement, which is hard to take back later.

If you actually receive a “we are raising your rent” notice, work through these steps calmly, in this order.

Five steps for a rent increase notice. One, do not sign on the spot, because signing is treated as agreement. Two, check whether your contract is a standard lease or a fixed-term lease. Three, pay your current rent until it is settled; if a court confirms the increase, you pay the gap plus 10% a year. Four, keep a record of every exchange and keep the notice. Five, if unsure, ask the Consumer Affairs Center (188), Houterasu or your school's international office. Houterasu's free consultation is for people with income and savings under set limits.

Step 1, do not sign anything on the spot, matters most. Signing a notice or a consent form gets treated as agreement, which is hard to reverse later. It is fine to simply say “let me check and get back to you.” A lease is not covered by Japan’s 8-day cooling-off rule (the covered transactions are listed by the National Consumer Affairs Center: cooling-off, in Japanese), so the only safe moment to stop is before you sign.

Is there a reason for the increase?

The letter may only say “due to various circumstances.” You do not have to stop there. Article 32(1) of the Act on Land and Building Leases lists three situations in which a rent increase can be requested.

The 3 reasons the law gives for a rent increase (Act on Land and Building Leases, Art. 32(1)): 1 taxes and other costs went up, 2 land or building prices or the economy changed, 3 the rent is much cheaper than similar rooms nearby. If the contract says rent will not go up for a set period, it cannot go up during that period

You can check the third one yourself. On an apartment search site, look at about five rooms near the same station, of a similar size and age, and note their rent. If your current rent is not lower than theirs, the case for an increase is weaker. Save the screens so you can show them when you talk.

Read your contract again too. If it promises that the rent will not go up for a set period (a special clause), the landlord cannot request an increase during that period (the proviso to the same Article 32(1)).

To ask for the reason politely, you can say:

「値上げの理由を、教えていただけますか。」 (Neage no riyū o, oshiete itadakemasu ka.) Could you tell me the reason for the increase?
「近くの同じような部屋の家賃と、比べた資料はありますか。」 (Chikaku no onaji yō na heya no yachin to, kurabeta shiryō wa arimasu ka.) Do you have anything comparing it with similar rooms nearby?
「少し考えたいので、お返事は来週でもいいですか。」 (Sukoshi kangaetai node, o-henji wa raishū demo ii desu ka.) I would like some time to think. May I reply next week?

If you are told “no renewal unless you pay more”

Shortly before a two-year contract ends, renewal papers arrive with a new rent written on them. An increase often comes up at this point. For an ordinary lease, the law has rules here as well.

Decision chart for a rent increase at renewal (Act on Land and Building Leases, Arts. 26 and 28, ordinary lease): if the landlord did not give notice in the window from 1 year to 6 months before the end, saying it will not renew, or will not renew unless the terms change, the lease is renewed on the same terms, with no fixed term. Even with notice, refusing renewal needs justifiable grounds. Do not sign renewal papers with a new rent on the spot. A fixed-term lease is different: it ends, then you re-sign

Under Article 26, if the landlord does not tell you, in the window from one year to six months before the end of the term, that they will not renew, or will not renew unless the terms change, the lease is treated as renewed on the same terms (though the renewed lease no longer has a fixed term). Even with such notice, if you keep living there after the term ends and the landlord does not object without delay, the result is the same.

Even when notice was given, the landlord needs “justifiable grounds” to refuse renewal (Article 28). This is judged by weighing how much the landlord and the tenant each need the building, the history of the lease, the state of the building and similar factors. The law does not say you must leave at once because you did not accept an increase.

So do not sign renewal papers with a new rent on the spot. Signing means you agree to the new rent. A fixed-term lease ends and is followed by a new contract, so it works differently (see the FAQ below).

When talks do not settle it: conciliation, and depositing your rent

“Court” sounds frightening, but a rent increase does not normally go straight to court. Under Article 24-2 of the Civil Conciliation Act, conciliation (a mediated discussion at the summary court) must come first, before a lawsuit.

What happens when talks do not settle it (Civil Conciliation Act Art. 24-2, Act on Land and Building Leases Art. 32(2), Ministry of Justice deposit Q&A): 1 talk, 2 conciliation at the summary court, required before a lawsuit, 3 court, where an upheld increase means paying the shortfall with 10% interest a year. Until then, pay your current rent on the due date. If the landlord refuses it, deposit it at the Legal Affairs Bureau. Being asked for more is not yet a refusal

Meanwhile, keep paying your current rent on the due date. If you stop paying, you fall into rent arrears, which is a separate problem from the increase.

Sometimes a landlord refuses to accept the current rent and says they will only take the new amount. In that case you can deposit the rent with the Legal Affairs Bureau (供託, kyōtaku). However, according to the Ministry of Justice deposit Q&A (Q23, Japanese), simply being asked for more rent does not yet count as a refusal. First try to pay your current rent on the due date. If the landlord still will not accept it, then you deposit it. You can do this at the bureau counter or online.

Say no, or accept? The choice is yours

So far this has been about why the landlord cannot decide alone – but accepting can sometimes be the better deal. Use this logic to decide.

Decision chart for accepting or refusing a rent increase. When a notice arrives, ask whether the reason is reasonable and cheaper than moving. If yes, accepting can be the smart choice if you are satisfied. If no, negotiate and pay your current rent meanwhile; if talks fail it goes to mediation, then court, and the court may allow an increase. Moving costs several hundred thousand yen, counting move-in costs and the move itself.

Moving comes with move-in costs (deposit, key money, agency fees) plus the cost of the move itself, often several hundred thousand yen in total. Move-in costs alone are typically 4 to 7 months’ rent, according to the MLIT apartment-hunting guidebook (PDF, Japanese), p.8. A small increase can genuinely be cheaper to accept than to move away from. On the other hand, if the increase is large or the reason is unclear, negotiate. If talks fail it can go to court, and the court may allow an increase. The first step is always a discussion between the two of you – meaning the final call belongs to you.

One thing that strengthens your negotiating position: knowing you have a cheap place to move to is the strongest card you can hold. X-House in Tokyo, for example, has zero deposit, zero key money, a 30,000 yen move-in cost, and rent starting at 30,000 yen. Being able to say “another increase and I will move” puts you on equal footing with your landlord. See X-House rooms (no deposit, no key money) ->

Frequently asked questions

Q. If I refuse the increase, will I be evicted?

No. Under a standard lease, refusing a rent increase alone is not grounds for forced eviction. If you cannot agree, paying your current rent is enough until a court decides (Article 32 of the Act on Land and Building Leases).

Q. I was asked to sign a rent increase notice.

Do not sign it on the spot. Signing gets treated as agreement. Say “let me check the details and get back to you,” then review your contract and where to get advice.

Q. If I refuse, which rent amount should I pay?

Until a court decides, you pay what you consider a fair amount, which is usually your current rent (Article 32(2)). If the court confirms the increase, you pay the shortfall plus interest of 10% a year. If the landlord refuses to accept the payment, there is a legal deposit procedure (kyotaku) through the Legal Affairs Bureau. If you are unsure, contact a Consumer Affairs Center or Houterasu.

Q. Does a fixed-term lease work differently?

Yes. A fixed-term lease (teiki shakka) ends at a set date, and terms can change when you sign a new contract. If a fixed-term lease has a clause on how the rent is revised, the Article 32 rule that lets you pay what you consider fair until a court decides does not apply (Article 38(9)). Check your own contract first to see whether you have a standard lease or a fixed-term one. A fixed-term lease is re-signed rather than renewed, with its own rules for leaving early, set out in fixed-term vs standard leases and renewal fees.

Q. Where can I get advice?

Your municipal Consumer Affairs Center (call 188) and your school’s international student office offer free consultations. Houterasu (Japan Legal Support Center) offers free legal consultations to people whose income and savings are under set limits (Japanese). Bring your evidence – the notice and any records of communication – when you go.
