How to Understand a Japanese Lease Contract: 2026 Fees, Renewal & Move-Out Guide

The first question is whether the apartment uses an ordinary building lease or a fixed-term building lease. Do not assume the difference from the listing or the advertised contract period. Find the lease-type wording in the contract itself and confirm it with the agent or landlord.

For an ordinary lease, statutory renewal rules can apply. Under the Act on Land and Building Leases, a landlord's refusal to renew or notice of termination is not simply a matter of reaching the printed end date; legal requirements can apply, including justifiable-ground rules. A fixed-term lease is different: it is designed to end at the agreed expiration date without renewal.

A valid fixed-term building lease must follow special formalities. The contract can be concluded in writing or by an electronic record, and the landlord must explain in advance that there will be no renewal and that the lease ends when the period expires. If that advance explanation is not provided, the non-renewal provision is invalid. This is one reason the lease type should be checked before you compare prices.

• Lease agreement and all addenda or special-clause pages
• Important-matters explanation provided in the transaction
• Initial-cost and recurring-payment statement
• Building, garbage, bicycle, parking, pet and noise rules
• Personal-guarantor or rent-guarantee-company agreement
• Required insurance policy or coverage summary
• Move-in condition report, equipment list and key record

Check the legal name of the landlord, the management company, the broker, the tenant, every approved occupant and any guarantor. Confirm where formal notices must be sent and who is authorized to approve changes. The person who showed you the apartment may not be the person who can legally change the lease.

Match the building name, room number, address, floor area, storage, parking, bicycle space and other exclusive-use areas to the property you actually inspected. If the listing promised a feature that matters to you, make sure the contract or an authorized written attachment identifies it.

Equipment status can create repair disputes later. Confirm whether items such as the air conditioner, stove, lighting, refrigerator, washing machine, internet equipment or furniture are landlord-owned fixtures, supported equipment, tenant property, or items left behind without a repair obligation.

• Correct building and room number
• Every person who will actually live in the unit
• Parking, bicycle and storage rights
• Landlord-owned appliances and fixtures
• Emergency and repair contact details
• Any promised furniture removal, replacement or installation

A Japanese lease can contain several dates that look similar but have different consequences: application date, contract date, rent start date, key-handover date, move-in date, lease expiration date, renewal-response deadline and cancellation-notice deadline. Put them on one timeline before signing.

Check whether rent begins before you physically move in and whether any free-rent campaign applies only to base rent or also to common fees and other recurring charges. If the property is not ready on the expected handover date, ask what the contract says about delayed cleaning, repairs or construction.

Cancellation timing deserves special attention because the physical moving day and the contractual end date can differ. A late notice can create an extra month of rent even after you have already left the room.

• Contract start and end dates
• Rent start date and first payment date
• Key-handover and permitted move-in date
• Renewal decision and payment deadlines
• Tenant cancellation notice period
• Short-term cancellation penalty period
• Final rent calculation rule: daily, full month or another method

Do not rely on a single 'initial cost' total. Separate each charge by recipient, purpose, refundability and future renewal. A low advertised rent can still produce a high first-year cost if the contract adds common fees, guarantee fees, insurance, support services or renewal-related charges.

The lease or attached cost statement should identify the monthly rent, common-area or management fee, parking or storage charges, payment method, transfer or debit fees, deposit, key money, advance rent, brokerage fee, guarantee-company fees, insurance and any lock-change or support-service charges.

If a charge is described as mandatory, ask where that obligation appears in the contract. If it is optional, ask whether declining it changes the screening result or the lease terms. Keep the written cost estimate with the final signed documents so you can compare what was promised with what was charged.

• Refundable deposit versus non-refundable key money
• Guarantee-company initial, monthly and renewal fees
• Insurance premium and renewal cycle
• Lock change, cleaning or support-service charges
• Bank transfer or direct-debit fees
• Parking, bicycle, storage, internet or water charges

A security deposit secures obligations such as unpaid rent and other lease-based debts. Under the Civil Code, the landlord returns the remaining balance after the lease ends and the property is returned, after deducting qualifying obligations. The tenant cannot unilaterally require the landlord to treat the deposit as the final month's rent.

A rent-guarantee company does not erase the tenant's rent obligation. It may pay the landlord under the guarantee arrangement and then seek reimbursement from the tenant. Read the separate guarantee agreement for initial fees, renewal fees, collection charges, late-payment rules and required notifications. If a personal guarantor is used, confirm the stated maximum liability.

Insurance is also separate from the lease. Check who is insured, what property and liability are covered, the policy period, deductible, exclusions, renewal process and claim contact. Do not assume the landlord's insurance protects your belongings or your liability to neighbors.

• Deposit amount, permitted deductions and refund method
• Guarantee-company fees and reimbursement obligations
• Personal-guarantor maximum liability if applicable
• Fire, household, personal-liability and tenant-liability coverage
• Water-damage and accidental-damage exclusions
• Policy renewal and cancellation rules

For an ordinary lease, read the contractual renewal procedure together with the statutory framework. Check the renewal fee, administration fee, updated guarantee or insurance requirements, response deadline and whether the contract describes automatic renewal or another process. A landlord's non-renewal or termination is not governed only by whatever is convenient for the landlord; the Act on Land and Building Leases contains tenant-protective rules.

For a fixed-term lease, the central point is that there is no renewal. If the fixed term is one year or longer, the law requires the landlord to notify the tenant of the end of the lease during the period from one year to six months before expiration in order to assert termination at the expiry date; a late notice can delay when termination becomes enforceable. Re-contracting may be possible, but it is a new agreement and should never be assumed.

Fixed-term residential tenants also have a statutory early-termination route in a limited situation: for residential premises under 200 square meters, unavoidable circumstances such as job transfer, medical treatment or caring for relatives that make continued use as the tenant's home difficult can allow termination one month after notice. Contract-based cancellation rights may be broader, so read both the statute and the signed clause.

• Ordinary or fixed-term lease
• Renewal fee and administration fee
• Guarantee and insurance renewal dates
• Landlord notice provisions
• Tenant cancellation method and recipient
• Short-term cancellation penalty
• Whether a fixed-term re-contract is merely possible or actually promised

The Civil Code places the basic obligation for repairs necessary to use the rented property on the landlord, except where the need for repair is attributable to the tenant. The tenant should report leaks, broken locks, electrical problems, equipment failure, mold and other defects promptly because delay can make damage worse and create a dispute over responsibility.

Read any small-repair clause carefully. Some contracts let the tenant handle minor items, but that is different from transferring every repair cost to the tenant. Confirm the contact route, emergency number, approval process and whether a landlord-owned appliance is included in the landlord's repair responsibility.

Also read the entry clause. The MLIT model lease generally treats landlord entry as something that requires the tenant's consent except for necessary or emergency circumstances. Your signed contract may contain its own procedures, so understand when management can enter, what notice is expected and how emergencies are handled.

• Who receives repair reports
• Which fixtures belong to the landlord
• What the tenant may repair without prior approval
• Emergency entry procedure
• Notice for inspections or maintenance
• Responsibility for consumables such as bulbs, filters or batteries

A lease can be financially reasonable and still be unsuitable if the usage rules conflict with how you live. Check restrictions on pets, smoking, musical instruments, remote work, business registration, customer visits, guests, additional occupants, subletting, short-term accommodation, bicycles, parking and common-area storage.

General listing phrases such as 'pets negotiable' or 'office use negotiable' are not enough. If the condition matters, get the exact approval in writing: animal type and number, extra deposit, cleaning terms, permitted work activity, approved occupants, parking space or bicycle-registration procedure.

Building rules provided in a separate booklet can still be contractually important. Ask for them before signing, not after move-in, especially if your schedule, family situation, pet, bicycle or work pattern depends on those rules.

• Pets and pet-related deposit or restoration rules
• Smoking and balcony restrictions
• Musical instruments and quiet hours
• Remote work, business use and customer visits
• Additional occupants and long-term guests
• Subletting and short-term accommodation
• Bicycle, parking, garbage and common-area rules

Special clauses are where many expensive surprises appear. Read them before you sign the main page. Look for professional cleaning, air-conditioner cleaning, key or cylinder replacement, smoking or pet restoration, short-term cancellation penalties, free-rent repayment, fixed deposit deductions, abandoned-property handling and other charges that do not appear in the headline rent.

For each special clause, identify the trigger, the exact work or area covered, the amount or calculation method, whether there is a cap, and whether the charge applies regardless of actual damage. If the wording says the tenant pays 'all repairs' or 'all restoration,' ask for a concrete explanation of what that means.

Official restoration guidance stresses clear agreement when a special clause shifts costs beyond ordinary allocation. The latest 2026 consumer-affairs warnings also show that restoration and cleaning clauses remain a frequent source of disputes. The safest time to resolve an unclear clause is before signing.

• Trigger for the charge
• Fixed amount, cap or calculation formula
• Whether ordinary wear is included
• Cleaning and air-conditioner-cleaning charges
• Key or lock replacement
• Smoking, pet, mold and water-damage rules
• Short-term cancellation and free-rent repayment

Japanese law does not treat ordinary wear and age-related deterioration as tenant-caused damage. Civil Code Article 621 excludes ordinary wear and aging from the tenant's basic restoration obligation and also excludes damage caused by reasons not attributable to the tenant. MLIT's restoration guidelines use the same general distinction between ordinary use and tenant-caused damage.

Tenant responsibility can arise from intentional acts, negligence, misuse, failure to report a problem that then becomes worse, or another valid contractual allocation. Examples can include moving damage, burns, unauthorized alterations or mold that expands because a serious leak or condensation problem was ignored. The amount can also depend on the damaged area, age of the material and valid special clauses.

Photograph the apartment immediately after receiving the keys and keep a dated condition record. At move-out, compare the same areas and ask for an itemized settlement. Do not sign a move-out acknowledgment you do not understand merely to finish the handover quickly.

• Ordinary wear and aging versus tenant-caused damage
• Move-in condition photos and checklist
• Repair history and written reports
• Itemized move-out charges
• Age and affected area of damaged materials
• Special clauses that change the default allocation

Act early and keep the discussion in writing. Identify the exact clause, amount, repair, notice or promise in dispute and send a concise record to the broker, management company or landlord. Preserve the listing, application, important-matters explanation, lease, special clauses, messages, receipts, photographs and repair reports.

Do not create a second problem by withholding rent, refusing required access, abandoning the room or violating another clause as a self-help response. For restoration or consumer disputes, local consumer-affairs centers and the National Consumer Affairs Center can provide guidance. Housing consultation services and legal professionals can help when the issue involves termination, eviction, large claims or interpretation of a disputed clause.

The practical objective is to separate three things: what the law says, what the signed contract says, and what the evidence shows actually happened. A written timeline and complete document set make that comparison much easier.

• Write down the disputed clause and amount
• Preserve all documents, messages, photos and receipts
• Request an itemized explanation for charges
• Use official consumer or housing consultation channels
• Seek qualified legal advice for termination, eviction or high-value disputes
