Japan Rental Contract Clauses to Read and Negotiate
Japan rental contract clauses decide what you can do in the unit and what you pay when you leave.1 The monthly rent gets the attention at signing, but the use restrictions, the special-clauses section, and the restoration rule cause the expensive surprises later.
Procedures, fees, and requirements can change. Confirm current details at Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Overview
This article covers the ordinary lease (futsū shakuya keiyaku, "ordinary building lease"), the renewable default residential contract, at the signing stage.2 It walks through each clause worth finding before you sign: pets, smoking, noise, the special-clauses section, subletting, and restoration.
Which lease this article covers
Almost every residential lease in Japan is an ordinary lease under the Act on Land and Building Leases (Shakuchi Shakka Hō, "Act on Land and Building Leases").2 A fixed-term lease (teiki shakuya keiyaku, "fixed-term building lease") works differently and genuinely ends at expiry. If your cover sheet says 定期借家, stop here and confirm which type you are signing, because the renewal assumptions in this article do not apply to it.
MLIT's restoration guideline assumes private rental housing at roughly market rent.3 It is meant to be read at contract signing, not only at move-out. The guideline itself carries no legal force; each dispute ultimately turns on the contract and the unit's condition.3
Use Restrictions: Pets, Smoking, Noise
These clauses govern daily life after the key handover. They look like boilerplate at signing and read like binding rules at move-out.
Pet-prohibition clauses
Most residential leases prohibit keeping dogs, cats, and similar animals outright.1 Where a pet-OK (petto ka, "pets permitted") term exists, it usually limits species, size, or number rather than opening the door to any animal. Confirm the exact permission in writing, including which animals and how many.
A pet prohibition matters twice. Breach itself can trigger warnings or termination steps under the contract.1 And damage your animal causes, including scratches on pillars, wall damage, and odor, is a textbook tenant-burden item in the Tokyo restoration explanation.4 MLIT's standard-contract commentary even gives the exchange explicitly: a landlord may permit indoor pet-keeping in return for the tenant bearing the full wall-cloth replacement cost as a special clause.3 Pet damage stays in your column, but the replacement cost still depreciates with the fixture's age: wallpaper is written down over about six years, so a full-price bill for six-year-old wallpaper overcharges you no matter who caused the mark.1
Pet-attributable damage stays your burden, and keeping an animal the contract forbids removes your normal-wear defense for related damage.1 Only properties with explicit written permission are safe if you have a pet.
Smoking-prohibition clauses and resale-room cleaning fees
Indoor-smoking bans commonly extend to the balcony and common areas in practice.1 Nicotine staining and odor left by smoking inside the unit count as tenant-attributable damage, not normal wear. Deodorizing and stain restoration beyond ordinary cleaning then fall on you at move-out.34
Read the clause for scope, not just presence. Some contracts ban smoking inside the room but say nothing about the balcony; others ban it across the property. A smoking-related cleaning surcharge written as a fixed amount follows the same enforceability test as any cleaning special clause: explicit scope plus clear agreement, explained in the special-clauses section below.5
Music and noise clauses
Leases routinely restrict musical instruments, loud audio, and late-night noise.1 Check whether the clause names specific instruments, sets quiet hours, or bans playing entirely. A unit that forbids piano practice is a different home from one that merely asks for quiet after 10 p.m.
Repeated violations can escalate. Persistent rule-breaking is a standard cancellation ground in residential leases, though eviction itself still requires legal process.1 The practical consequence usually arrives earlier anyway, as written warnings from the management company.
The Special-Clauses Section (Tokuyaku)
The special-clauses section (特約, tokuyaku, "special provisions departing from the default rule") sits near the end of the contract.4 This is where terms that override the default tenant protections hide. Read it line by line before signing, because everything above it reads as standard while this section rewrites the deal.
A special clause is valid only if three things hold together: the clause objectively reads as a special agreement, you actually agreed to it, and its content is not void as unreasonably one-sided.4 The following diagram shows the test in the order a tenant should apply it.
Fixed-amount move-out cleaning fees
The most common special clause fixes your move-out cleaning fee (hausu kurīningu tokuyaku, "professional-cleaning special clause") at a set amount.5 Such a clause can bind you when you explicitly agreed to it after it was read and explained.4
Standing Supreme Court case law from 2005-12-16 sets two conditions: the tenant-burdened scope of ordinary wear must be stated specifically in the clause itself, and you must have clearly agreed to it.5 A clause that meets both conditions shifts costs you would otherwise never owe.
But a bare line is not enough. Courts have repeatedly read vague wording, such as a single line saying the cleaning fee is the tenant's full burden, narrowly: it covers only professional cleaning actually commissioned to make up for insufficient cleaning by you, not a flat fee charged regardless of the unit's condition.5 A 2013 Tokyo District Court decision is the frequently cited example of this narrow reading.
For the clause to hold reliably, it should say that a fixed charge applies regardless of the cleaning actually performed, that it covers the landlord commissioning the work, and that you owe a reasonable amount.5 If your contract lacks that specificity, ask for it to be spelled out or struck before you sign. The Tokyo-model explanation treats roughly ¥25,000 as the yardstick for a full professional move-out clean (as of 2026-05; confirm current figures with your broker or management company).5
Consumer advisories flag clauses billing the tenant for all replacement costs regardless of fault, such as one documented case demanding full cloth and floor replacement on a roughly ¥30,000-rent unit.6 Question or refuse that shape of clause before signing; post-signature changes are rarely possible.
Unilateral cleaning and oversized-furniture charges
Beyond the standard cleaning fee, watch for one-sided cost shifts: all repair costs on the tenant regardless of cause, oversized-furniture handling surcharges, or air-conditioner cleaning billed at both entry and exit.6 A 2025 consultation case shows the pattern: entry-time air-conditioner cleaning paid once, then billed again at move-out under a buried line in the important-matters sheet.6
Even a clearly agreed clause can fail on content. If it is unreasonably one-sided, it may be void under Consumer Contract Act Articles 9 and 10 or Civil Code Article 90.57 The test is content, not just signature.
Wall-mount and furniture restoration follows the same logic at a smaller scale. Small pin and pushpin holes that need no base-board replacement are normal use on the landlord's side.1 Anchor bolts, large screws, and fixed shelving that need filling and repainting sit on your side of the line.
How to read any tokuyaku before signing
The Tokyo model explanation states the general rule first, that aging plus normal use sits landlord-side, and then requires every departure from it to be identified as an exception special clause.4 Use that structure as your reading method: find the general rule in your contract, then list every exception claimed after it.
MLIT frames restoration as an entry problem, not an exit problem: confirm the restoration conditions and every special clause at signing with both sides sharing the same understanding, and verify the unit's condition jointly on the way in and the way out.3 Consumer advisories add the practical step: compare your contract against MLIT's standard contract and guideline, get the fee breakdown in writing, and resolve every ambiguity on the spot.8
In Tokyo, the broker must deliver and explain a dedicated restoration document apart from the important-matters sheet, covering the general rule, any special clauses, repair duties, and contact points.9 Outside Tokyo, no such duty exists, so request the same explanation yourself.
Subletting and Unauthorized Occupancy
What the subletting ban covers
Residential leases routinely prohibit subletting or transferring the lease without the landlord's consent.1 The ban covers room-level sublets, Airbnb-style short-stay lodging, and handing the lease to a friend. Some contracts now name vacation-rental platforms explicitly.1
The statute backs the clause. Under Civil Code Article 612, a tenant may not sublet without the landlord's consent.10 Breach is a standard termination ground in the contract, though courts require the breach to have destroyed the relationship of trust before a termination stands, so a single unauthorized sublet may or may not clear that bar.1
A detected short-stay listing or undisclosed roommate arrangement can trigger a termination notice under standard terms, and outcomes turn on the facts.1 Written consent before the fact is the only safe path.
Guests, cohabitation, and business use
Caps on occupant numbers, approval requirements for added cohabitants, and bans on running a business from a residential unit are routine.111 The specific numbers are contract-specific, so read yours rather than assuming a norm. MLIT's standard form restricts adding new cohabitants other than by birth and restricts month-plus continuous absence without process.11
Operating a shop, hosting paying guests, or registering a business address at a residential unit without approval breaches the use clause. Confirm any home-office or guest arrangement that goes beyond ordinary living before you commit to it.
Modifications and Restoration to Original Condition
What counts as restoring to original condition
Restoration to original condition (原状回復, genjō kaifuku, "restoration to original condition") means restoring only damage from your intent, negligence, breach of duty of care, or beyond-normal use.3 It explicitly does not mean returning the unit to its move-in-day state. That single distinction settles most move-out arguments before they start.
Since the 2020-04-01 Civil Code revision, Article 621 writes the distinction into statute: ordinary-use wear (通常損耗, tsūjō sonmō, "ordinary wear from normal use") plus aging deterioration (経年変化, keinen henka, "aging deterioration over time") are excluded from your restoration duty.108
Even damage that is yours depreciates with time. The older the fixture at move-out, the smaller your share; wallpaper is widely treated as losing value over about six years to a residual value of around ¥1 afterward.1 After six years of tenancy, a full-price wallpaper replacement bill contradicts the depreciation logic outright.
| Burden | Examples |
|---|---|
| Landlord side | Sun-faded wallpaper, furniture dents, small pin holes, soot darkening behind appliances4 |
| Tenant side | Spilled-drink stains left uncleaned, scratches from dragging furniture, mold from neglected ventilation3 |
Restoration disputes remain the largest single rental complaint category. The national consumer-affairs network logged 13,273 restoration consultations in 2023, 13,312 in 2024, and 14,711 in 2025, with 1,846 in the first months of 2026 (as of 2026-05-31; confirm current figures with the National Consumer Affairs Center).12 A 2026 advisory roundup shows the recurring shapes: post-inspection surprise bills, full replacement charges after six-plus years of tenancy, pet-damage claims without photo evidence, and cleaning fees billed twice.6
Unauthorized modifications and what needs consent
Structural modification (増改築, zōkaichiku, "structural extension or remodeling"), repainting, large-hole drilling, and fixture installation without written landlord consent are routinely prohibited.111 Unauthorized work becomes tenant-burden restoration at move-out, priced as repair rather than improvement.
The repair duty runs the other way during the tenancy. Equipment the unit came with stays landlord-side in principle; report leaks, breakdowns, and faults immediately and do not repair unilaterally, or the unauthorized work itself becomes a second dispute.68 Fixtures a prior tenant abandoned, such as a leftover air conditioner or light fitting, generally carry no landlord repair duty, so confirm whose equipment each item is at signing.1
Good to know
Photograph every wall and floor on key-handover day
Joint checklists with photos at entry and exit are the guideline practice, and court outcomes have turned on whether entry photos exist.3 Long-tenancy disputes, including cases after ten and twenty years of residence, routinely center on pre-existing marks nobody can prove.8 Walk the unit with the agent, photograph every scratch and stain with timestamps, and keep the files until the deposit settles.
Demand the restoration explanation before signing, not after moving in
Tokyo brokers owe you a dedicated restoration explanation for new brokered residential leases signed from 2004-10-01 onward; renewals and private landlord deals are excluded.913 Outside Tokyo the duty does not exist, which is exactly when you must request the equivalent walkthrough yourself. Ask which restoration items are general-rule and which are special-clause exceptions, and get the answer against the written text.
Spoken concessions at signing bind nobody until written in
A waived cleaning fee, a pet permission, or a shortened notice period spoken aloud is worth nothing until it appears in the signed contract.1 Consumer advisories direct tenants to clear every ambiguity on the spot, because changes after signature are rarely possible and the signed Japanese original controls over any summary.8
