First, keep this in mind: monthly rent ≠ the amount you need to pay when signing the contract
In some areas, arrangements like “one month’s deposit and three months’ rent upfront” and “the deposit is refunded in full when you move out” are common. Applying those assumptions in Japan will seriously underestimate the cash you need for your first month. According to the Ministry of Land, Infrastructure, Transport and Tourism’s “Room Search Guidebook,” when signing a private rental contract, the total of 敷金/礼金/agency fees/compensation insurance premiums/rent, etc., is estimated at around 4～7 months’ rent Guide. In other words, for a place with monthly rent of 8 万円, you may have to pay 32～56 万円 upfront on the day you sign.
Only a small portion of this amount (敷金) is theoretically refundable. 礼金, 仲介手数料, 保証料, and insurance premiums are basically “gone for good.” The right way to prepare is to calculate your “one-time costs for your first month after arrival” completely separately from your “regular monthly expenses.” The biggest mistake in an estimate like “one month’s living expenses ×12” is leaving out this entire upfront-cost bill.
The figures vary year by year depending on the city, property, and contract month. All ranges below are reference estimates; before signing, compare the important-matters explanation, contract, and initial-cost breakdown item by item, and ask which fees are refundable and when payment is due.
Avoid These 5 Costly MisconceptionsExperience
Misconception 1: 敷金 is a deposit and is refunded in full when you move out
敷金 (shikikin, security deposit) is theoretically refundable, but at move-out, costs for 「原状回復」 (restoring the unit), unpaid rent, and disposal of items left behind are deducted before the remainder is returned. It is not unusual to receive little or nothing, or even owe more. Remember: 敷金 does not mean you will recover the full amount.
NoteAn important safeguard: On move-in day, photograph every corner of the room, including existing marks and stains on walls, floors, and plumbing areas. These are key evidence at move-out that “I did not cause this damage,” and a step many students renting in Japan for the first time overlook.
Misconception 2: 礼金 is also a deposit and can be refunded later
礼金 (reikin, key money) is a nonrefundable gift to the landlord. In 関東, it is commonly about 1–2 months' rent. Guide Mistaking it for a refundable deposit is one of the most common budgeting errors among first-time renters in Japan.
NoteProperties with no 礼金 exist, but there are fewer to choose from. In 関西, 「保証金 + 敷引き」 is often used instead; the arrangement works differently (see below).
Misconception 3: It’s enough to look only at the monthly rent
The advertised 「家賃」 often excludes 管理費/共益費 (a fixed monthly charge). At signing, you may also need to pay one-time costs such as 仲介手数料, a guarantor-company fee, fire insurance, and advance rent. Looking only at the 「賃料」 figure can leave a large amount out of your budget.
NoteActual monthly payment = 賃料 + 管理費/共益費; the actual cost of moving in = monthly payment + the full initial-cost bill.
Misconception 4: Paying the guarantor company’s fee guarantees you can move in
It is a misconception that “using a 家賃保証会社 and paying the fee guarantees approval.” Your 入居審査 may still be rejected if you lack stable residence status, proof of income, or an emergency contact in Japan. Paying a fee does not guarantee approval.
NotePreparing an emergency contact (often a person in Japan or a school contact), proof of enrollment, and scholarship/remittance records in advance can greatly reduce the chance of rejection. Housing listed through your school's international office or co-op as 「外国人友好」 is often a safer option.
Misconception 5: Student dorms / UR housing are always the cheapest option overall
Student dormitories and UR賃貸 do have low initial costs (UR has no key money, brokerage fee, renewal fee, or guarantor requirement), but dormitory places are limited and have eligibility and move-in-period rules. UR's monthly rent is not necessarily the lowest among all options. Treat them as lower-initial-cost alternatives, not as the default scenario.
NotePrepare your budget assuming a private rental, and treat student dorms, UR, and public housing as lower-cost alternatives when available. Do not use the cheapest option to estimate the overall budget.
Breaking Down the Upfront Costs: What You’ll Pay for an Apartment with Monthly Rent of 8 万円Variable
敷金（しききん）— around 1～2 months’ rent Guide
Similar to a security deposit and generally refundable, but restoration costs and unpaid rent are deducted at move-out. The official estimate is about 2 months' rent. In 関西, it may instead take the form of 「保証金」.
- Budget 0–2 times the monthly rent (official estimate: about 2 months)
- In your budget, mark this as “possibly partly refundable,” not definitely refundable
- Take photos as evidence on move-in day and keep the 入居時チェックリスト
Watch outMistaking 敷金 for a full refund at move-out is a major financial pitfall. Under Ministry of Land, Infrastructure, Transport and Tourism guidance, deterioration over time and ordinary wear and tear are the landlord's responsibility; you can dispute excessive deductions.
礼金（れいきん）— commonly around 1～2 months’ rent in the Kanto region Guide
A gift to the landlord; it is never refunded. Properties with no 礼金 exist, but are less common.
- Prioritize properties listed as 「礼金ゼロ」 or 「礼金0」 to save this cost
- Count 礼金 as a one-time sunk cost, not money you can recover
Watch outIn 関西, 「保証金 + 敷引き」 (a fixed deduction at move-out) is common in place of 礼金. Applying 関東 assumptions in 関西 can lead to larger deductions.
仲介手数料（媒介手数料）— capped at 1.1 times the monthly rent To verify
A fee paid to the real-estate agent. MLIT sets the general combined cap for the landlord and tenant at 1.1 times the monthly rent (including tax); it is nonrefundable.
- Check that the quote does not exceed the legal cap of “monthly rent × 1.1”
- Some companies offer half-price or free brokerage-fee promotions; compare them
- Housing arranged through your school's international office or co-op may sometimes waive or reduce this fee
Watch outLooking only at rent and missing this one-time payment is a common pitfall. The fee has a legal cap; be wary of quotes above 1.1 months' rent.
studyinjapan.go.jpAdvance rent / prorated rent — approx. 0.5–1.5 monthsTo verify
Rent paid in advance when signing. Official guidance: Rent in Japan is usually paid one month in advance; if you move in mid-month, rent for that month is prorated by the day.
- Moving in at the start versus the end of the month makes a big difference to your first month's cash outlay
- If possible, schedule move-in for the start of the month to avoid overlapping prorated rent and the next month's advance rent
Watch outIf your move-in date is inconveniently late in the month, you will need to pay both prorated rent for that month and the next month's advance rent, which feels like a much larger expense.
Fire / damage insurance premium — approx. ¥10,000–¥20,000 / 2 yearsGuide
Almost always required when signing; it is not optional. Real-estate agencies often include a specified policy by default.
- Ask whether you can bring your own less expensive 家財保険 (tenant's insurance policy); this is often allowed.
- Confirm the coverage amount, policy period (usually renewed every 2 years), and renewal date
Watch outThe specified policy included by default can often be replaced with a cheaper one of your choice. If you do not know you can ask, you may simply accept the quoted policy.
Lock replacement fee — approx. ¥10,000–¥20,000Guide
A lock replacement fee for changing the door lock before you move in. The amount varies greatly by property.
- Confirm whether this is mandatory (some charges may be negotiable)
- Ask 「これは必須ですか」 about questionable add-ons such as deodorizing or antibacterial treatment as well
Watch outSmall charges for 鍵交換, deodorizing, antibacterial treatment, and similar items may not seem large individually, but together they can blow your first-month budget.
Initial rent guarantee company fee — approx. 35%–50% of monthly rent (2 years)To verify
If you do not have a Japanese co-signer (連帯保証人), international students generally need a 家賃保証会社. The initial fee is about half a month's rent, followed by an annual renewal fee.
- Confirm the initial guarantor fee and annual renewal fee
- Prepare an emergency contact, proof of enrollment, and proof of income or remittances for the 入居審査
- Properties listed as 「外国人可」 generally pay particular attention to this screening process
Watch outPaying the guarantor fee does not guarantee approval; applicants without stable residence status, income, or an emergency contact may be rejected.
Furniture, appliances / bedding — approx. ¥30,000–¥150,000Guide
The official estimate of 「4～7 months' rent」 above generally excludes furniture and appliances. An unfurnished unit means you must buy everything yourself.
- Check whether the property is furnished or unfurnished
- For an unfurnished unit, set aside extra money for a bed, refrigerator, washing machine, microwave, and other essentials
Watch outThe University of Tokyo Housing example of about 489,000 yen explicitly excludes furniture and appliances; this is another hidden expense beyond the initial costs.

| Scenario | Estimated initial costs | Why |
|---|---|---|
| Tokyo · Private studio (University of Tokyo example) | About 489,000 yen (excluding furniture and appliances) To verify | University of Tokyo Housing Office example: an unfurnished 20㎡ room with monthly rent of 80,000 yen plus a 5,000-yen management fee costs about 488,580 yen upfront; deposit/key money, brokerage, guarantor, and insurance together bring it close to six months' rent |
| Standard private rental | About 4–6 months' rent Guide | MLIT's overall estimate is 4–7 months; in Tokyo's 23 wards, with key money, a guarantor company, or an inconvenient move-in date, it can approach 6–7 times the monthly rent |
| UR rental housing | Clearly lower Guide | No key money, brokerage fee, renewal fee, or guarantor requirement; main initial costs are a 2-month deposit, prorated rent, and common-area fee, but monthly rent is not necessarily the lowest |
| Student dormitory / international exchange hall | Lowest; often no deposit or key money Guide | JASSO: Student dormitories usually have no deposit, key money, or renewal fee, but places are limited and move-in periods are restricted, so apply very early |
How to bring this bill downExperience
- Use temporary housing when you first arrive: It is almost impossible to sign a private long-term lease online before coming to Japan (you need a residence card, Japanese bank account, property viewing, and emergency contact). Stay first in a student dormitory, monthly rental, or share house, then find a permanent home once settled.
- Prioritize housing through your school's international office or co-op: Foreign-friendly units are limited, and school channels may include institutional guarantees or reduce guarantor and brokerage fees, so they are easy to miss.
- Prioritize properties listed as 「礼金ゼロ」 or 「仲介手数料無料/半額」: These are two of the largest one-time sunk costs, so save them when you can.
- Apply for student dormitories very early: Utilities are included and initial costs are lowest, but there are few rooms and availability often does not line up with admission dates. Apply as soon as you see an opening.
- The 重要事項説明 (重説, explanation of important matters) is the key time to ask questions: a 宅建士 must explain restoration obligations, special clauses, and renewal fees. Ask 「これは必須ですか」 about questionable items such as 鍵交換 and deodorizing, and request that they be removed if possible.
- Watch for special clauses in the lease: A single line such as 「クリーニング特約/張替え特約」 may shift costs that the landlord would normally bear to you, leaving you to pay tens or hundreds of thousands of yen at move-out. These clauses are easy to overlook at signing.
- In 関西, watch for 保証金 + 敷引き: A fixed 「敷引き」 amount is deducted from the guarantee deposit at move-out whether or not the room is damaged. Applying 関東 assumptions in 関西 may result in larger deductions.
