Understanding Japanese Rental Contracts: What to Watch For

Once you settle into a Japanese rental home, the lease agreement—often called a "rent contract" or "rental contract"—is a legal document that outlines everything from the monthly rent to the responsibilities of both tenant and landlord.
If the language, terminology, and legal expectations vary significantly from what you’re familiar with, it’s essential to read the contract carefully and know what to watch for.

1. Pinpoint the basic terms.

• The real‑estate agent or landlord’s name who represents the property.
• The lease duration (normally 1 or 2 years) along with start and end dates.
• The rent per month and the payment deadline (usually the 10th).
• If the unit is furnished or unfurnished..
• The deposit (shikikin) and key money (reikin) amounts. The deposit can be refunded; key money is a non‑refundable goodwill payment to the landlord..

2. Understand the deposit and key money.
• The deposit generally equals 1–3 months’ rent, covering damage or unpaid rent. The landlord ought to issue a receipt and a copy of the deposit slip..
• Key money typically equals 1–2 months’ rent, is paid once and not refunded. If concerned, negotiate early; some landlords may accept a reduced key money or waive it for reliable tenants..
• Be alert for extra "security deposit" clauses that may be concealed in the wording. Some contracts use "保証金" (guarantee money) or "敷金" (shikikin). Ensure you understand the distinction and handling..

3. Understand the guarantor or guaranty company.
• In Japan it is common to require a guarantor (guarantee person) or a guaranty company (e.g., Aoyama Gakuin, M&A, or a local bank)..
• The guarantor’s responsibility usually equals the entire rent plus a few months’ more. A written guarantee is required..
• When employing a guaranty company, note that they levy a fee (commonly 10% of the yearly rent)..
• Check the contract for the guarantor’s conditions, especially whether the guarantor can be released after a certain period or if the guarantee automatically renews..

• Clarify which utilities (electricity, gas, water, internet, trash collection) are included in the rent and which are separate..

• With individual gas and electricity meters, the contract may require separate payments..
• Also watch for any "parking fee" or "storage fee" if the unit provides parking or storage..

6. Subletting and guest policy.
• Most Japanese contracts forbid subletting without the landlord’s written consent..
• If you plan to have a long‑term guest or roommate, discuss this in advance..
• Some contracts permit "roommates" (同居人) but demand the landlord’s approval..
• Inspect the clauses that explicitly ban "転貸" (subletting) or "転居" (co‑living)..

7. Renewal and termination terms.
• The contract will usually state whether it can be renewed automatically or if renewal requires a new agreement..
• Most leases can be renewed annually, but the landlord may increase the rent..
• If ending early, you usually must give 1–3 months’ notice, often 60 days..
• The agreement may impose a penalty for early termination, like forfeiting the deposit or paying part of the remaining rent..
• If you plan to move before the contract ends, negotiate a "退去料" (move‑out fee) or a "退去手数料" (move‑out service fee) that might be waived..

8. Notice of changes in rent or contract terms.
• Rent increases are permissible only once per year during renewal..
• Any rent increase must be written in the contract or a formal notice ("賃料改定通知")..

• Some landlords require a pet deposit (ペット保証金) and a pet fee (ペット賃料)..
• The contract could also outline breed and size limits..

10. Language and translation issues.
• Contracts are usually written in Japanese. If you’re not fluent, ask for a translation or have a trusted friend read it..
• Even with Japanese fluency, read the contract twice, concentrating on ambiguous or legally significant sections..
• Keep a copy of the signed contract in both Japanese and any translated version you may have..

11. Final checklist before you sign.
• Verify that all the details discussed (rent, deposit, key money, guarantor, utilities, pet policy) match what is written in the contract..
• Confirm the move‑in date, the procedure for handing over keys, and the condition of the property (photos, inventory list)..
• Request from the landlord or agent a copy of the building’s fire safety certificate and maintenance logs..
• Make sure you receive a receipt for any payments made before the move‑in date..
