Preventing Security Deposit Return Disputes: Practical Steps to Take Before Moving Out
Security deposit disputes commonly arise when moving out of rental housing. By understanding the legal nature of security deposits and the proper scope of restoration to original condition, and by learning about evidence preservation and claim procedures, you can protect your rights against unfair charges.
What is a Security Deposit? Understanding its Legal Nature and Market Rates
A security deposit is money that a tenant deposits with the landlord (property owner) at the time of signing a rental lease agreement to cover unpaid rent or restoration costs at the time of move-out. With the amendment to the Civil Code that took effect in April 2020 (Article 622-2), the definition of security deposits and return rules were formally codified. It is defined as "money paid by a tenant to a landlord for the purpose of securing the tenant's obligation to pay money to the landlord arising from rental obligations and other matters under the lease," and is ultimately "money held in trust"—not the landlord's property.
The typical amount varies by region and property type, but generally ranges from one to two months' rent. In Tokyo, one month's rent is becoming the standard. The principle is that security deposits must be returned with legitimate restoration costs and unpaid rent deducted; a landlord refusing to return the deposit without legitimate reason is breaking the law.
Importantly, the obligation to return a security deposit arises "after the lease terminates and the tenant vacates the property." In other words, the return obligation begins from the date the keys are returned. Under the Civil Code, if no return deadline is specified, it should be within a "reasonable period"; in practice, requesting return within one month of move-out is standard.
Scope of Restoration Obligations: Understanding the MLIT Guidelines
Most security deposit disputes stem from differing understandings of who should bear restoration costs. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has published "Guidelines for Disputes and Best Practices Regarding Restoration to Original Condition," which sets standards for cost allocation between tenant and landlord.
Costs borne by the tenant (lessee)
•Damage from intentional or negligent acts (cigarette burns, children's markings on walls, scratches on flooring from carelessness, etc.)
•Damage from misuse (damage or odor from keeping pets in a no-pet building, mold from inadequate ventilation, etc.)
•Upgrade costs exceeding restoration obligations (limited to intentionally damaged areas)
Costs borne by the landlord (lessor)
•Normal wear and tear and age-related deterioration (natural degradation from time passage and normal use)
•Discoloration of wallpaper or tatami mats from sunlight
•Floor indentations or carpet marks from furniture placement
•Small nail or pin holes (that do not reach the base board)
While the MLIT Guidelines do not have binding legal force, they are referenced in court decisions as important standards and have become the de facto industry standard. Some landlords and property management companies mistakenly believe that "tenants must restore the unit to its original condition," but this is legally incorrect. Wear and tear from normal living is a cost the landlord should bear.
Common Patterns of Unfair Charges and How to Counter Them
Knowing which costs are commonly wrongly deducted from security deposits is the first step in preventing disputes.
Case 1: Treating normal wear and tear as tenant responsibility
Examples include "discoloration of wallpaper is the tenant's responsibility" or "charging the full cost of flooring replacement." Normal wear and tear is the landlord's responsibility as a matter of principle, and you can refuse to pay unless the contract contains a special clause. Even if a special clause exists, it may be deemed invalid if it is "not specifically detailed," "the tenant was not adequately informed," or "there was no economic compensation in rent."
Case 2: Excessive cleaning fees
Requests like "cleaning costs at move-out (50,000–100,000+ yen) are the tenant's full responsibility" warrant caution. When normal cleaning has been performed, cleaning costs are the landlord's responsibility as a matter of principle. However, if the contract explicitly states "move-out cleaning costs are the tenant's responsibility" and you received this explanation at move-in, it may be recognized as a valid special clause.
Case 3: Ignoring useful life standards
The useful life for wallpaper (vinyl) is six years according to the National Tax Agency's standard useful life tables. Even if the tenant is at fault, only the residual value based on years used can be charged. For example, wallpaper that has been in use for six years or longer requires almost zero tenant contribution toward replacement, even if the tenant caused damage.
The basics of rebuttal are to communicate in writing that "in accordance with the MLIT Guidelines, normal wear and tear is the landlord's responsibility." It is important to remain calm and negotiate with evidence.
Evidence Preservation Before Moving Out: Photos and Move-out Inspections Are Essential
The most effective way to prevent future disputes is to document the condition of the room at move-in and move-out.
What to do at move-in
•Take photos and videos of the room's condition before moving in (walls, floors, ceilings, fixtures—everything)
•Note any scratches, stains, or malfunctions in the move-in checklist and formally report and file with the property management company
•Always save email and written correspondence
What to do at move-out
•After moving out furniture, take photos and videos of the entire unit before the move-out inspection
•Always participate in the move-out inspection and confirm the details on the spot
•Do not sign the "move-out inspection confirmation" or "move-out checklist" until you have thoroughly reviewed the contents. If there are unclear points, you can ask to review them later
•If you are told "we will send an invoice later," take notes on any damage that can be confirmed on the spot
Signing ambiguously during inspection makes it difficult to object later. A signature on "confirmed" may indicate agreement to charges, so take time and be careful.
Claiming Your Security Deposit When It's Not Returned
If more than one to two months have passed since move-out without the deposit being returned, or if an clearly unfair amount has been deducted, follow these steps:
Step 1: Written request to property management or landlord
First, communicate in writing (email or postal mail)—not by phone—that you are requesting the return of the deposit. Oral agreements easily become disputes.
Step 2: Sending a registered letter with acknowledgment of receipt
If the written request is ignored, send a registered letter formally requesting the security deposit return. The post office can send a registered letter, which officially records the fact and contents of the document. Including a statement like "if the deposit is not returned by [date], I will consider legal action" puts pressure on the other party.
Step 3: Small claims court
If the claim amount is 600,000 yen or less, you can use small claims court. Small claims procedures are simplified, typically resolved in a single hearing, and allow self-representation without an attorney. If you file a complaint with the court and the other party does not appear, your claim is generally recognized. Filing costs are modest—just court fees of a few thousand yen depending on the claim amount—making this an economical option.

Summary: Knowledge is Your Greatest Weapon
Most security deposit disputes can be prevented or resolved if tenants have the correct knowledge. Just keeping three key points in mind—"normal wear and tear is the landlord's responsibility," "cost allocation according to useful life," and "evidence preservation at move-out"—allows you to firmly counter unfair charges.
Get in the habit of keeping records from the moment you move in, and take time to review documents carefully when you move out. This alone can prevent losses of tens of thousands of yen. If negotiations become difficult, do not struggle alone; consult early with a consumer affairs center or Legal Terraces. Remember: a lease is a contract, and tenants have legitimate rights.
