Japan Landlord Maintenance Obligations and Tenant Remedies

Providing a habitable space is not a suggestion in Japan; it is a strict contractual obligation under the Civil Code. Landlords must act swiftly to address maintenance issues, as recent 2020 law revisions have heavily empowered tenants with financial remedies—including automatic rent reductions—when landlords delay repairs.

The Obligation to Make Necessary Repairs

Article 606 (1) of the Japanese Civil Code dictates: "A lessor shall assume the obligation to make repairs necessary for the use and profit of the leased property." This encompasses everything from the structural integrity of the roof and walls to the functional status of all embedded equipment (air conditioners, water heaters, toilets, stoves) provided with the unit.

When the Landlord is Exempt

The landlord is generally not responsible for repairing items if:

1. The damage was caused intentionally or through the negligence of the tenant (the tenant pays for this).
2. The specific broken equipment was explicitly defined as a "Leftover Item" (Zanchibutsu) in the lease. A Zanchibutsu is usually an AC unit or stove left by a previous tenant; the landlord "gifts" its use but legally disclaims any responsibility to repair or replace it when it breaks.

Minor Repairs Clause (Shoshuzen Tokuyaku)

The landlord's obligation to repair is not absolute for tiny issues. Standard leases contain a valid "Minor Repairs Clause," which shifts the financial burden to the tenant for replacing consumable, inexpensive items such as:

• Exchanging lightbulbs
• Replacing faucet washers/packing to stop minor drips
• Replacing sliding screen doors (Shoji/Fusuma) paper

Under consumer law, you cannot use this clause to force a tenant to pay for expensive repairs like replacing a broken air conditioning compressor.

2020 Civil Code Revision: The Tenant's Right to Self-Repair

A major legal shift occurred in 2020 to prevent landlords from ignoring repair requests (Article 607-2).

If a tenant notifies the landlord that a repair is necessary and the landlord fails to perform the repair within a "Reasonable Time," OR if there is an "Urgent Need" (e.g., a burst pipe flooding the apartment), the tenant is legally permitted to hire a contractor and perform the repair themselves.

Furthermore (Article 608), after performing the repair, the tenant has the right to demand immediate reimbursement for the total cost of the necessary repair from the landlord. If the landlord refuses to pay, the tenant is legally permitted to offset the repair costs from their next month's rent payment.

Mandatory Rent Reductions (Article 611)

Perhaps the most impactful 2020 revision is the "Automatic Rent Reduction" rule.

When part of the leased property is lost or becomes unusable through no fault of the tenant, the rent is "decreased in proportion to the value of the part that can no longer be used." The previous law stated the tenant could request a decrease; the new law states it decreases automatically by right.

The MLIT Disrepair Exemption Guidelines

To prevent chaotic disputes over "how much rent is deducted for a broken AC," industry associations (like JPM) and the MLIT established broad deduction guidelines. These outline a "Grace Period" (Menseki kikan) for the landlord to fix the issue, after which the rent is percentage-reduced per day.

Examples of Deduction Guidelines:

• Toilet Unusable: 1-day grace period / 30% monthly rent deduction
• Bath/Water Heater Broken: 3-day grace period / 10% monthly rent deduction
• Water Stoppage: 2-day grace period / 30% monthly rent deduction
• AC Unit Malfunction: 3-day grace period / ~5,000 JPY monthly deduction

(Example: If a tenant in a 100,000 JPY/month apartment loses hot water for 23 days because the landlord delayed buying a new heater, subtracting the 3-day grace period leaves 20 days. The landlord would owe a mandatory rent refund of roughly 6,666 JPY).

Landager's comprehensive maintenance ticketing system records the exact date and time of tenant requests, automatically dispatching preferred vendors to ensure repairs are completed well within the statutory "Reasonable Time" guidelines, protecting landlords from surprise self-repairs and mandated rent revenue losses.
