Will Rising Prices Push Up Your Rent in Japan? Reading a Rent Increase Notice
On August 21, Japan's Ministry of Internal Affairs and Communications released the July nationwide Consumer Price Index (core, excluding fresh food). The exact figures are best checked in the official release, but the broader trend of prices continuing to rise year-on-year has not changed. Against this backdrop, more tenants are receiving notices from their landlord announcing a rent increase starting the following month.
For readers unfamiliar with rent revisions in their home country, this notice can be confusing. This article explains when these notices arrive, whether a landlord can simply raise the rent unilaterally, and what to do if you disagree with the new amount.
When does a rent increase notice typically arrive?
Rent increase notices can arrive either around lease renewal time or partway through a fixed-term contract. Common reasons cited include rising rents for comparable units nearby, higher costs for the landlord such as property tax, or the need to recoup major building repair expenses. The notice usually states the current rent, the proposed new rent, when it would take effect, and the stated reason.
Can a landlord raise the rent unilaterally?
In short, a landlord's notice alone does not automatically finalize a new rent amount. Japan's Act on Land and Building Leases allows either the landlord or the tenant to request a future rent adjustment when the current rent has become unreasonable in light of changes in property taxes, general economic conditions, or comparable rents nearby. That right to request an adjustment exists, but unless the tenant agrees, the matter is generally expected to go through discussion or conciliation first.
That said, some lease contracts include a special clause stating rent will not be increased for a set period, which would generally take precedence; other contracts renew automatically with no rent change. The first step is checking exactly what your own lease says.
What if you don't agree with the increase?
Rather than simply refusing to pay, the practical first step is to ask the landlord or management company for the basis of the increase — such as data on comparable rents nearby — and request a discussion. If no agreement is reached, disputes under the Act on Land and Building Leases are, in principle, required to go through civil conciliation at a Summary Court before litigation. While discussion or conciliation is ongoing, it is generally understood that continuing to pay the previous rent amount is sufficient; if the landlord refuses to accept payment, depositing the rent with a Legal Affairs Bureau (kyotaku) is another option worth exploring.
Is a rent increase the same as a renewal fee?
A rent revision and a renewal fee (koshinryo) are legally distinct. A renewal fee is a one-time payment tied to a special clause in the lease at renewal time, while a rent revision changes the ongoing monthly rent itself. Because notices for both sometimes arrive around the same time, it's worth checking each line item on your bill separately to see which portion is which.

Act on Land and Building Leases
Handled at Summary Court
Relevant legal provisions
- Act on Land and Building Leases, Article 32(1)
- When the current rent has become unreasonable due to changes in taxes on the land or building, fluctuations in the general economy, or a comparison with rents for similar nearby buildings, either party may request a future rent adjustment, regardless of the contract terms — unless a special clause fixes the rent for a set period.
- Act on Land and Building Leases, Article 32(2)
- If the parties cannot agree on an increase, the party receiving the request is generally considered to have satisfied their obligation by paying an amount they consider reasonable, until a court determines the increase is justified.
- Civil Conciliation Act, Article 24-2
- Disputes concerning land and building leases must, in principle, first be brought to civil conciliation before a lawsuit can be filed.
Rent revision vs. renewal fee
| Item | Rent revision (increase) | Renewal fee |
|---|---|---|
| Legal basis | Act on Land and Building Leases, Art. 32 | Special clause in the contract (no uniform legal duty) |
| What it affects | The ongoing monthly rent itself | A one-time payment made at renewal |
| Effect without consent | Not automatically finalized; discussion/conciliation expected | Arises as a contractual obligation if the clause exists |
| If you disagree | Discuss/conciliate; paying the old rent is generally sufficient meanwhile | Limited room to dispute the clause's validity itself |
Common mistakes and how to avoid them
✕Transferring the new, higher rent right after receiving the notice, out of surprise — and later being treated as having agreed to it.
→If you disagree, say so in writing before paying, and keep transferring the previous rent amount.
✕Agreeing to the increase without checking whether the lease already has a clause fixing the rent for a set period.
→As soon as a notice arrives, check the rent-revision clause in your own lease first.
✕The landlord refuses to accept the old rent payment, and it ends up recorded as unpaid rent.
→If the landlord refuses payment, look into depositing the rent with a Legal Affairs Bureau, and consult a professional if needed.
✕A renewal fee bill and a rent revision notice arrive around the same time, and the combined total gets accepted without checking each part.
→Break down each item on the bill or notice separately and confirm the legal basis for each.
Checklist for when a rent increase notice arrives
- Checked the stated reason and basis for the increase on the notice
- Checked whether the lease has a special clause about rent revisions
- Checked the gap between old and new rent, and any comparable-rent data cited as justification
- If disagreeing, communicated that in writing or email
- Continued paying the previous rent amount while discussion is ongoing (or looked into a legal deposit)
- Distinguished a renewal fee charge from a rent revision when checking amounts
- Considered Summary Court civil conciliation or a professional consultation if needed
Frequently asked questions
- Q. Do I have to start paying the new rent as soon as I get the notice?
- A. No, not immediately. If you disagree, you can state your objection and continue paying the previous rent amount while discussion or conciliation is ongoing.
- Q. Can a tenant request a rent decrease instead?
- A. In principle, yes — Article 32 grants the adjustment-request right to both landlords and tenants. That said, a special clause in your lease may limit this.
- Q. Can I be evicted just for not agreeing to the increase?
- A. Terminating a lease and demanding a move-out solely because a tenant hasn't agreed to a rent increase is generally not considered straightforward to justify. The situation differs if there are other issues, such as unpaid rent.
- Q. Can foreign residents use civil conciliation too?
- A. There's no nationality requirement. Since proceedings are conducted in Japanese, it's advisable to bring an interpreter or get support from a professional.
