Initial Costs When Renting in Japan: Deposits, Key Money, Fees & Budget Checklist

The first payment for a private rental in Japan can combine several different types of cost. Some are rent paid in advance, some secure obligations under the lease, some pay for services, and some are one-time non-refundable charges.

Not every apartment uses every fee, and the same fee name can be handled differently from one contract to another. Treat the written estimate and lease as the source of truth for the property you are actually renting.

• Prorated rent for the contract-start month
• Rent for the following month
• Management or common-service fees
• Security deposit (shikikin)
• Key money (reikin), if required
• Real estate brokerage fee
• Guarantor company fee
• Fire or household insurance
• Lock-change, cleaning, support or other property-specific charges

If your lease begins in the middle of a month, the first bill may include prorated rent for the remaining days plus all or part of the next month's rent. A management or common-service fee may be prorated or prepaid on a similar schedule.

This timing can make the move-in bill look much higher than the regular monthly payment. Confirm the exact contract start date, the day from which rent is charged, the first regular payment date, and whether the estimate includes the following month's rent.

• Check the contract start date and key-handover date separately
• Confirm how prorated rent is calculated
• Add the management fee when comparing regular monthly housing cost
• Ask when normal monthly payments begin after move-in

A security deposit is held to secure obligations under the lease. Under Japan's Civil Code, a lessor who receives a security deposit must return the remaining amount after deducting qualifying lease-related obligations when the lease ends and the property is returned, subject to the contract and applicable law.

Key money is a different payment. Where a contract requires it, it is generally treated as a non-refundable payment rather than money held as security. Because properties may require one, both, or neither, compare the full move-in estimate instead of assuming that a lower deposit automatically means a cheaper rental.

• Ask whether the deposit has any fixed deduction or special restoration clause
• Check when any remaining deposit is returned after move-out
• Confirm whether key money is required and whether the estimate describes it as non-refundable
• Keep the estimate, lease and move-in condition records for later reference

If a real estate broker arranges the rental, the estimate may include a brokerage fee. Brokerage remuneration is regulated, but the amount you pay can depend on the transaction structure and the agreement with the broker.

Ask the agency to show the brokerage fee as a separate line item, state whether tax is included, and explain when the fee becomes payable. If the amount changes between the initial quote and the final estimate, ask for the reason in writing before signing or paying.

• Fee amount and whether consumption tax is included
• Who is charging the fee
• When the fee becomes payable
• What happens to the fee if the transaction does not proceed

Many private rentals use a rent-guarantee company. The tenant may pay an initial guarantee fee at contract time, and the guarantee plan can also include renewal, monthly, collection or other recurring charges.

Do not evaluate the guarantor cost from the initial fee alone. Ask for the guarantee company's fee schedule and confirm what amount is due at signing, what repeats later, and how payment is collected.

• Initial guarantee fee
• Annual or periodic renewal fee
• Monthly guarantee or collection fee
• What rent and other charges are included in the guarantee base
• What happens if the payment method changes

The estimate may also contain fire or household insurance, a lock-change fee, cleaning charges, emergency-support services, disinfection or other property-specific items. These charges are not standardized across all rentals.

For every line you do not recognize, ask who requires it, what service it buys, when the service is performed, and whether it is mandatory under the property or contract. Do not simply remove a charge from the estimate on your own; first confirm whether doing so would change the rental conditions.

• Insurance coverage, policy period and renewal method
• Whether the lock will actually be changed and when
• Whether cleaning is charged at move-in, move-out or both
• Whether support services are required or optional
• Whether any item will be charged again later

What happens to money already paid can change depending on whether you cancel before the landlord accepts the application, after screening, after signing the lease, or after the lease has started. Different payments may also have different refund rules.

Before sending a large payment, ask for the cancellation rules and keep proof of every transfer. If you later cancel, request a written settlement showing which amounts are returned, retained or applied to an existing obligation.

• Application and screening status
• Whether the lease has already been concluded
• Contract start date
• Which services have already been performed
• Written refund or cancellation provisions

Foreign residents may need to coordinate residence documents, a Japanese phone number, payment methods, emergency contacts or guarantor requirements before the contract can proceed. The required combination varies by landlord, management company and guarantee company.

If the explanation is only in Japanese and you do not fully understand a major cost or obligation, ask for clarification before signing. MLIT and the Tokyo Metropolitan Government publish rental-housing guidance for foreign residents, including multilingual information.

• Your name and personal details are correct on every document
• The required payment method is available to you
• Guarantor or guarantee-company requirements are understood
• You know who to contact about payment or contract questions
• You have copies of the estimate, important explanations and lease documents
