What a guarantor is in Japan

In Japan, most private rentals ask you to provide a guarantor—someone who promises to pay if you can’t. You’ll see two common terms:

Joint and several guarantor (rentai hoshōnin 連帯保証人): a person with identical payment responsibility as you.
Guarantor company (hoshō gaisha 保証会社): a private firm that acts as your financial back-stop for a fee.

A third contact often appears on forms:

Emergency contact (kinkyū renrakusaki 緊急連絡先): a person the landlord/agent can reach if they can’t contact you. This person is not responsible for paying rent or damages and is different from a guarantor. Universities and housing support pages clarify this distinction and note that applications commonly require an emergency contact.

Throughout this guide, we’ll show you alternatives if you don’t have a personal guarantor, how guarantor companies work, and how to read the fine print in your lease.

Guarantors and Rental Contracts in Japan: What Expats Need to Know

Do you always need a guarantor?

Not always. Here are mainstream paths where a guarantor may not be required:

UR (Urban Renaissance Agency) housing: Government-affiliated rental stock (over 700,000 units nationwide) where no guarantor, no key money, and no renewal fee are standard selling points. Multiple official/agency pages for UR highlight these benefits.
Corporate lease (hōjin keiyaku 法人契約): Your employer signs the lease or backs it formally. Landlords often prefer corporate contracts because the company is the responsible party; several brokerage guides explain the differences and why corporates are favored.
University support and student programs: International students can sometimes use university schemes or the JEES Comprehensive Renters’ Insurance that helps secure or ease the burden on a guarantor. Many universities explain the program and how it works.
Some serviced apartments and share houses: Policies vary, but many operators accept residents without a personal guarantor (often substituting a guarantor company or larger deposit). Check each operator’s contract.

If you don’t have a guarantor: guarantor companies explained

How they work: The landlord or agent forwards your application to a guarantor company, which screens your credit, income, visa/residency status, and stability. If approved, the company guarantees your rent. You pay:

Initial fee: commonly 40%–100% of one month’s rent, depending on the provider and profile.
Renewal/annual fee: often a fixed amount or a percentage each year.

English-language explainers consistently describe these typical ranges and acceptance across Japan.

Pros: No need to ask a friend or colleague to take on heavy legal risk. Faster screening when documents are ready.

Cons: Fees add to move-in costs; late payments may incur reminder/collection fees per the guarantor company’s rules.

Legal basics and protections for guarantors

Before signing, it helps to know the baseline legal rules that influence Japanese leases and guarantees:

Guarantee must be in writing (or valid electronic record). The Civil Code states that a guarantee contract is ineffective unless made in writing.
Maximum liability (kyokudogaku 極度額) for individual guarantors. Since the 2020 Civil Code reform, if an individual is guaranteeing obligations under an ongoing contract (e.g., tenancy obligations), the contract must state a maximum guaranteed amount; otherwise the individual guarantee is invalid. Leading law firm explainers apply this to lease guarantees.
The official Civil Code English translation also sets out detailed rules for revolving guarantees (continuous obligations) including the requirement to stipulate a maximum amount.

What this means for you: When a landlord asks for a human guarantor, expect to see a clause that caps the guarantor’s total exposure (e.g., “up to ¥X including rent arrears, damages, and fees”). If this cap is missing, ask the agent to include it—Japanese practice and international counsel commentary say it should be there for an individual guarantor.

The two standard lease types in Japan

Most residential leases fall into one of two buckets:

Ordinary lease (futsū shakuyakeiyaku 普通借家契約): the default. Often 2-year terms, renewable, and relatively tenant-protective under Japan’s lease laws. Renewal fees (kōshinryō) are common in many areas.
Fixed-term lease (teiki shakuyakeiyaku 定期借家契約): no automatic renewal; you must vacate when the term ends unless a new contract is signed. Sometimes priced a little lower; no renewal fee by definition because there’s no automatic renewal.

About renewal fees: Japan’s Supreme Court ruled in 2011 that, if clearly written and not excessive, renewal fee clauses are valid. If your contract states a fee at renewal, you should plan for it.

Common move-in costs and what they cover

Initial costs vary by city and property, but your quotation may include several items. Here are typical line items many expats encounter:

Upfront cost item	Typical range or note	Who it’s paid to	Notes
First month’s rent	Prorated if mid-month	Landlord/PM	Often due before move-in
Deposit (shikikin)	1–2 months typical (UR is usually 2 months)	Landlord	Refundable minus cleaning/repairs per guidelines
Key money (reikin)	0–2 months common; non-refundable	Landlord	Cultural practice; not required by law; varies by region and property
Agent/broker fee	Up to 1 month’s rent (plus tax), if applicable	Agency	Standard in private rentals
Guarantor company fee	~40%–100% of one month’s rent (initial) + annual fee	Guarantor company	Amount varies by provider
Renter’s (fire) insurance	Often ¥20,000–¥40,000 for 2 years	Insurer (sometimes via agency)	Usually required in lease
Lock/key exchange	Fixed amount (varies)	Landlord/PM	Common on move-in/out

Industry and informational sources back these typical expectations, including UR’s deposit standard and “no key money/renewal/guarantor,” agent fee practice, guarantor fee ranges, and rental insurance norms.

Security deposits and “restoration” at move-out

Japan uses detailed guidelines to determine what is wear-and-tear versus tenant damage when returning deposits. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) publishes guidance that many landlords follow when settling deposits at move-out. Knowing these rules helps you argue fairly for your refund.

Quick examples from the MLIT approach:

Normal aging (faded wallpaper, minor sun discoloration) is not billed to the tenant.
Tenant-caused damage (large holes, heavy stains, unauthorized alterations) can be billed proportionally.

Screening: documents and how to pass smoothly

Most applications request some or all of the following:

Passport and residence card (zairyū card) or Certificate of Eligibility if applying from abroad.
Proof of income/employment (salary slips, tax slip, employment contract or offer letter).
Emergency contact in Japan (not responsible for payment).
Contact details for your employer or school; sometimes seal/inkan documents (less common as electronic signatures spread).

Brokerage and university guides outline these requirements and clarify the emergency contact’s non-payment role.

Tips to improve approval odds

Target rent ≲ a conservative share of monthly income.
Prepare PDFs (ID front/back, payslips, contract) before viewing.
If new to your job, attach your offer letter and savings statement.
If you truly lack a local contact, many agencies can suggest solutions for the emergency contact field.

Sample wording you should look for in the contract

When reviewing the lease and the separate guarantor/guarantee company agreement, scan for:

Guarantor cap (極度額): e.g., “Guarantor’s maximum liability is ¥X…”—this is a must for individual guarantors under current practice.
Lease type: ordinary vs fixed-term, with start/end dates.
Renewal terms and fees: whether there’s a renewal fee (kōshinryō). Valid if agreed and within reason.
Restoration/deposit clause: reference to MLIT guidelines or equivalent.
Early termination clause: notice period (often 30–60 days) and any short-term cancellation penalty if leaving within the first year. Universities and rental guides commonly note the 1–2 month notice and possible penalty if specified.

Table: Guarantor paths compared

Option	Who qualifies	Typical costs	Pros	Cons	Best for
Personal guarantor (連帯保証人)	Adult living in Japan with stable income; willing to submit documents	None to you	No company fee; personalized help	Heavy legal risk for the person; harder for newcomers	Those with close family in Japan
Guarantor company (保証会社)	Most renters; depends on screening	40%–100% of one month’s rent initial + annual fee	Fast, standardized; widely accepted	Extra upfront and annual costs	Most expats without a local guarantor
UR housing	Anyone meeting UR criteria	2 months deposit; no key money/renewal/guarantor	Lower friction; transparent costs	Unit selection limited; competitive	Those prioritizing clarity and stability
Corporate lease	Your employer signs	Company policies vary	High acceptance by landlords	You may need to move if job changes	Company-sponsored hires & transferees

Practical money notes to plan for

Insurance: Most private rentals require renter’s (fire) insurance. Guides peg common premiums around ¥20,000–¥40,000 for two years (depends on coverage).
Rent due date: Many leases require rent by the last business day of the previous month; always check your contract and the bank auto-debit setup.
Renewal fee budgeting: In Kanto especially, a one-month renewal fee at the two-year mark is common; Supreme Court precedent supports such clauses when reasonable and explicit.
Early exit: Expect 30–60 days’ notice; some contracts impose a short-term cancellation penalty (often one month’s rent) if you leave within the first year—if and only if your lease says so.

Frequently asked questions

Can my family member overseas be my guarantor?
Usually no. Most landlords want the guarantor to live in Japan so they can be contacted and, if needed, sued in Japanese courts. That’s one reason guarantor companies became mainstream.

What if the agent asks for an inkan (seal)?
Japan is increasingly accepting signatures and electronic contracts, and the legal requirement for guarantee contracts focuses on being in writing or electronic form, not on using a physical seal. That said, some agents still prefer seals for tradition.

Is key money mandatory?
No. Reikin is a custom (not a legal requirement) and varies by property and region. Many properties are “no key money” now, especially in new builds or competitive submarkets.

How are deposits settled at move-out?
Landlords commonly look to MLIT’s restoration guidelines to decide what’s normal wear vs. tenant liability. Photograph everything at move-in and move-out.

Do all leases auto-renew?
No. Ordinary leases typically do (with renewal fee if stated); fixed-term leases don’t. Read the “contract type” line on page 1.

Can my company sign instead of me?
Yes—corporate leases are common and often easier to pass because the company is obligated. Policies vary by employer.

Step-by-step: a smooth path to approval

Shortlist properties that match your situation. If you lack a guarantor, focus on listings that accept guarantor companies or consider UR stock.
Prepare documents early: ID, visa, proof of income, employer contact, emergency contact.
Know your numbers: Gather the initial cost quote (rent, deposit, key money, agent fee, guarantor fee, insurance). Cross-check each line item against the norms above.
Check the guarantor language: If using a human guarantor, confirm the maximum liability cap is written. If using a guarantor company, understand late-payment procedures and renewal fees.
Confirm the lease type and renewal costs: Ordinary vs fixed-term, renewal fee amount, and any short-term cancellation penalty.
At move-in: Photograph the unit thoroughly (walls, floors, fixtures). File photos alongside your inspection sheet for an easier deposit return under MLIT’s framework.

Table: Quick contract audit before you sign

Clause to confirm	What good looks like	Why it matters
Contract type	“Ordinary” with renewal details or “Fixed-term” with end date	Sets expectations on renewal and move-out
Renewal fee	Amount and timing stated	Budgeting; Supreme Court allows if clear/reasonable
Guarantor cap	Maximum liability clearly stated for individual guarantor	Required practice for validity of individual guarantees in ongoing contracts
Deposit/restoration	Reference to MLIT restoration rules or equivalent	Fair wear-and-tear guidance at move-out
Early termination	Notice period and any short-term penalty	Avoid surprise charges if leaving early

Regional and property differences to keep in mind

Renewal fees are more common (and often higher) in parts of Kanto than elsewhere; however, whether you pay one depends on your specific contract, not just geography. The legality rests on the contract’s clarity and reasonableness.
Key money trends shift with supply and demand. In competitive areas or brand-new properties, you may still see reikin; in others, it’s increasingly waived to attract tenants.
UR housing is standardized but unit availability and neighborhood options vary by city; start your search early if you want UR’s “no guarantor” path.

Final takeaways

You can rent in Japan without a personal guarantor—through UR housing, a guarantor company, or a corporate lease.
If a human guarantor is used, the guarantee must be in writing and should state a maximum liability for ongoing obligations. Don’t sign without that cap.
Budget realistically for initial costs (deposit, agent fee, guarantor fee, insurance) and ongoing costs (renewal fees where applicable).
Protect your deposit by documenting the condition at move-in; MLIT’s guidelines will likely frame any deductions at move-out.
