Article 32 of Japan’s Land and Building Lease Act (Shakuchi Shakka Hō, 借地借家法) allows a landlord or tenant to request an increase or decrease in agreed rent when tax burdens, economic conditions, or local market rents have materially changed. This is a Japan-specific legal mechanism for building leases, and it applies to both sides of the lease relationship. However, without evidence and a documented process, negotiations usually do not move forward.
For readers used to other markets, this does not work like an automatic annual escalation clause or a purely market-driven reset. In Japan, even if one party makes a formal request, the rent does not automatically change to the requested amount on that date.
Key points in this article
- A rent increase or reduction claim starts with changes in tax burdens, economic conditions, or a mismatch with comparable nearby rents.
- In an ordinary lease (futsū shakuyā, 普通借家), this rule operates as a mandatory provision, so the effect of special contract clauses requires careful review.
- In a fixed-term lease (teiki shakuyā, 定期借家), the outcome differs depending on whether the contract includes a rent revision clause.
- In practice, the basic discipline is to keep records in the order of market evidence, notice, negotiation, and mediation.
What does Article 32 of Japan’s Land and Building Lease Act allow?
Article 32 of Japan’s Land and Building Lease Act provides that when the rent under a building lease becomes unreasonable, either party may request an increase or decrease in rent for the future. It can be used not only for upward revisions during inflation, but also for downward revisions when market rents fall.
That said, making the request does not mean the rent automatically becomes the requested amount from that day. The usual path is agreement with the other party, then mediation, and ultimately court proceedings if needed to determine the appropriate amount.
The three main triggers for making a claim
| Trigger | Example | Materials to prepare |
|---|---|---|
| Increase or decrease in tax burden | Changes in fixed asset tax or city planning tax | Tax payment notices, property valuation certificates |
| Change in economic conditions | Changes in prices, interest rates, or land values | Official statistics, land price materials |
| Gap from nearby comparable rents | Difference from surrounding rents | Listing examples, closed-deal comparables, appraisal reports |
In practice, a claim is more persuasive when supported by multiple categories of evidence rather than pushed through on only one reason.
The difference between ordinary leases and fixed-term leases
In an ordinary lease (futsū shakuyā, 普通借家), a special clause that completely excludes the right to request rent adjustment is reviewed very carefully. By contrast, a clause that benefits the tenant, such as a promise not to raise rent for a certain period, may still operate effectively in some situations.
In a fixed-term lease (teiki shakuyā, 定期借家), the design of the rent revision clause becomes even more important. Future operation changes depending on whether the contract adopts no revision, revision by a fixed percentage, or revision through consultation.
Compared with many common-law markets, Japanese fixed-term leasing practice places heavier emphasis on the written contract structure than foreign investors may initially expect. A landlord who assumes that market movement alone will justify a later revision can run into limits if the lease language was not designed carefully at signing.
How to proceed with a rent increase or reduction claim
First, gather market materials and organize the gap between the current rent and the proposed revised rent, together with the reasons. Next, instead of relying on oral discussions alone, make the request in a form that leaves a record, such as a written notice or a certified mail notice.
If consultation does not resolve the matter, mediation should generally be considered. Rent disputes easily become emotional, so even where a property manager stands between the parties, keeping supporting documents and a clear timeline reduces the burden on personnel handling the matter.
Operational mistakes landlords should avoid
One approach to avoid in rent revision practice is asking for a sudden large increase only at renewal. Trust is better preserved by reviewing local market rents, capital expenditures, management quality, and changes in fixed asset tax every year and making smaller adjustments over time.
Rent also affects exit pricing. A difference of JPY 10,000 per month, roughly USD 65 to 70 depending on exchange rates, can influence income-capitalization value, while more vacancies or tenant move-outs can have the opposite effect. It is important to separate legal rights from business judgment.
Items that should be included in the notice
A rent increase or reduction notice is not just an emotional request. It is a legal expression of intent and the starting point for negotiation. Organizing the required contents makes it easier to explain the timeline later in negotiations or mediation.
| Item | Content |
|---|---|
| Lease being addressed | Property, contract date, rent amount, and parties |
| Substance of the request | Proposed rent after the increase or decrease |
| Grounds | Tax burden, economic conditions, nearby comparable rents |
| Desired timing | From when the revision should apply |
| Method of discussion | Reply deadline, candidate meeting dates, documents to be presented |
Building rent revision into asset management
Rent revision is not a right to use only when a dispute occurs. Each year, it should be treated as part of management oversight by reviewing fixed asset tax, nearby asking rents, closed rents, capital expenditures, and vacancy periods, then deciding whether revision is necessary.
Rather than suddenly presenting a large increase to a tenant, agreement is easier when the landlord explains management quality, repair history, and nearby market rents and discusses changes in stages. Before asserting the law, it is the accumulation of convincing materials that supports stable operations.
How to proceed when the parties cannot agree
Even if the parties cannot agree on a rent revision, that does not mean the relationship ends immediately. First, record the notice of intent, confirm the other side’s reasons for objection, and add comparison materials. Then consider cost and timing in the order of mediation, appraisal, and litigation.
From the landlord’s side, it is necessary to calculate not only the possibility of winning an increase but also the loss if the unit becomes vacant. From the tenant’s side, there are cases where the pre-existing rent must continue to be paid until a reduction claim is formally recognized. This is another area where Japanese practice can feel more process-driven than overseas readers may expect, particularly if they are used to faster interim rent resets or broader self-help remedies.
Frequently asked questions
Can a rent increase be requested at any time?
A. It can be requested if circumstances exist that show the current rent has become unreasonable, but the rent does not automatically change to the requested amount without agreement or mediation.
Does the same article also apply to rent reduction claims?
A. Yes. The same article applies. A tenant may also request a reduction based on falling market rents or changes in economic conditions.
Is certified mail mandatory?
A. It is not always legally mandatory, but in practice it is effective because it preserves the timing and content of the notice.
Can Article 32 be used in a fixed-term lease?
A. The outcome depends on the rent revision clause in the contract. Check the lease agreement to confirm whether the clause is valid and how it is structured.
