Guarantor (Hoshonin) vs Guarantor Company in Japan: What Renters Need to Know
Navigating the rental market in Japan can be complex, and one of the most significant hurdles for both Japanese and foreign renters is the requirement for a guarantor. Traditionally, this meant finding a personal guarantor (連帯保証人 or rentai hoshōnin), often a family member, who would be legally responsible for your rent and other lease obligations if you couldn't fulfill them. However, in recent years, guarantor companies (保証会社 or hoshō gaisha) have become the prevailing option. As of 2021, a survey found that 80% of rental management companies utilize a guarantor company, with 76% relying on them exclusively. Understanding the differences, costs, and implications of each is crucial for a smooth apartment search in Japan.
What is a Guarantor (Hoshonin) in Japan?
A personal guarantor, or rentai hoshōnin, is an individual, typically a Japanese citizen or permanent resident, who co-signs your lease agreement. Their role is to assume full financial responsibility for your rental obligations should you default on rent payments, damage the property, or incur other costs outlined in the lease. This is a significant responsibility, as the guarantor's liability is often substantial.
What are the responsibilities of a personal guarantor?
The primary responsibility of a personal guarantor is to act as a safety net for the landlord. If you, the tenant, fail to pay rent, damage the property beyond normal wear and tear, or breach other terms of the lease, the landlord can legally demand that the guarantor fulfill these obligations. This means the guarantor could be liable for unpaid rent, cleaning fees, repair costs, and even legal fees if a dispute arises.
What changed with the 2020 Civil Code reform?
A significant change occurred in April 2020 with the reform of the Japanese Civil Code (民法). Prior to this, a personal guarantor's liability was often uncapped, leaving them potentially responsible for an indefinite amount. The reform introduced a critical protection: any contract involving an individual guarantor must now specify a maximum liability cap (極度額 or gokudo-gaku) in writing,. Without this explicitly stated cap, the personal guarantee is legally invalid.
This cap is typically set at 12 to 24 months of rent. For example, if your monthly rent is ¥100,000, the gokudo-gaku might be ¥1,200,000 (12 months' rent). This provides clarity and limits the financial exposure for the individual guarantor, making it a "vastly easier ask" than before.
Is it difficult for foreigners to find a personal guarantor?
Yes, finding a personal guarantor is often very challenging for foreign residents in Japan. Landlords typically prefer family members or close relatives who are Japanese citizens or permanent residents with stable incomes. Many foreign residents do not have such connections, making this option largely impractical. Even for Japanese renters, finding an individual guarantor is becoming increasingly difficult.
What is a Guarantor Company (Hoshou Gaisha)?
A guarantor company (保証会社 or hoshō gaisha) is a private corporation that provides the same guarantee service as a personal guarantor, but for a fee. The tenant pays for this service, not the landlord. If you miss a rent payment, the guarantor company will pay the landlord first and then pursue you for reimbursement. This system has become the standard in Japan's rental market.
How do guarantor companies work?
When you apply for an apartment that requires a guarantor company, you'll sign an agreement with the company. The company then guarantees your lease to the landlord. If you fail to pay rent, the company steps in to cover the payment. Subsequently, their collections team will contact you to recover the owed amount. This process, where the company pays on your behalf and then seeks reimbursement, is known as 代位弁済 (daii bensai).
It's important to understand that guarantor companies do not directly sell their services to tenants. Instead, they form agency contracts (代理店契約 or dairiten keiyaku) with real estate brokerages and property management companies. This means that the specific guarantor company you use is usually designated by the property management company or landlord, and you often have limited choice in the matter. Property listings (bukken sheets) will often specify "保証会社加入必須" (guarantor company use required) or even name a specific company like 「指定 日本セーフティー」.
What are the typical fees for a guarantor company?
Guarantor company fees vary depending on the company and the specific plan. As of 2026, typical rates are:
| Type of Plan | Initial Fee | Renewal Fee |
|---|---|---|
| Standard | 50–100% of monthly rent | ¥10,000/year to 10% of monthly rent |
| Budget | 30–50% of monthly rent | ¥5,000–¥10,000/year |
| Credit-based (e.g., Orico, Jaccs, Aplus) | 30–50% of monthly rent | ¥100–¥200/month |
Data as of January 2026
Credit-based guarantor companies often offer lower fees because they assess your creditworthiness based on your credit card payment history. However, past credit defaults or delinquencies could lead to rejection. If the property management company designates a specific guarantor company, fee negotiation is usually not possible. However, if multiple plans are offered, you might be able to choose a more affordable option, so it's always worth asking.
What documents do guarantor companies require for screening?
Guarantor companies conduct their own screening process, which can be a point of unexpected difficulty for foreign renters. They need to assess your ability to pay rent. Here's a list of commonly requested documents:
- Residence Card (在留カード or zairyū kādo): Must have sufficient validity, ideally at least one year and preferably two years remaining to cover the full lease term.
- Passport: For identity verification.
- Certificate of Employment (在職証明書 or zaishoku shōmeisho): From your Japanese employer.
- Recent Payslips: Covering the last two to three months.
- Tax Returns (確定申告書 or kakutei shinkokusho): If you are self-employed, ideally for the last two or three years.
- Bank Statements: To demonstrate stable income or sufficient savings.
- Personal Seal (印鑑 or inkan) or Signature: Depending on the company's requirements.
What are the income requirements for guarantor companies?
Most guarantor companies maintain a consistent income standard: your annual income should be at least 36 times the monthly rent. This essentially means your monthly rent should not exceed one-third of your monthly take-home pay. For example, if your rent is ¥100,000 per month, your annual income should ideally be ¥3,600,000 or more.
What are common reasons for foreigners to be rejected by guarantor companies?
While income is a primary factor, foreign renters can face rejection for other reasons:
- Visa Validity: Many guarantor companies require your Residence Card to be valid for the entire lease term (typically two years). This can be a hurdle for individuals on Working Holiday visas, Designated Activities visas, or those who have recently arrived with only a one-year visa status. The Digital Nomad Visa, which does not include a residence card or juminhyō (resident registration certificate), presents additional difficulties as these are often required.
- Lack of Credit History: If you're new to Japan, you might not have a credit history, which some credit-based guarantor companies rely on.
- Past Issues: Previous payment defaults or delinquencies, even if from your home country (especially with credit-based companies), can lead to rejection.
- Discrimination: Although illegal, improper rejection based on nationality is a documented problem.
Guarantor vs. Guarantor Company: A Comparison
Let's break down the key differences between a personal guarantor and a guarantor company:
| Feature | Personal Guarantor (連帯保証人) | Guarantor Company (保証会社) |
|---|---|---|
| Cost | Free at signing for the tenant | Initial fee (30-100% of monthly rent) + recurring renewal fee |
| Liability | Capped by law (post-2020 Civil Code) at 12-24 months' rent | Unlimited internally for the company; landlord has full coverage |
| Screening | Landlord reviews guarantor's income/residency | Company screens tenant's income, visa, credit history |
| Operations | Reactive; landlord contacts guarantor if issues arise | Proactive; handles direct debit, identifies arrears, pursues tenant |
| Availability | Increasingly difficult to find, especially for foreigners | Widely available, often mandatory for listings |
| Legality | Must specify a gokudo-gaku (liability cap) | Unaffected by gokudo-gaku requirement |
| Choice | Tenant finds their own guarantor | Often designated by landlord/management company |
The 2020 Civil Code Change: One Guarantor Only
An important legal clarification from the 2020 Civil Code amendment is that landlords are prohibited from requiring both a personal guarantor and a rent guarantee company simultaneously clea.rent. You can only be required to provide one form of guarantee.
- If a landlord requires a guarantor company, they cannot also demand a personal guarantor.
- If a contract signed before April 2020 required both, the dual requirement is no longer enforceable.
While this is largely a non-issue for foreigners who struggled to find personal guarantors anyway, it's a useful protection if a landlord attempts to impose both requirements clea.rent.
What happens if I miss a rent payment with a guarantor company?
If a direct debit for rent fails, the guarantor company's collections team will typically contact you within days. If the payment is not resolved within the same month, the company will pay the landlord on your behalf (代位弁済 or daii bensai) and then pursue you for reimbursement.
It's crucial to understand your rights and the limits of a guarantor company's power:
- No Eviction Power: A guarantor company cannot unilaterally change your locks, enter your unit without permission, or terminate your lease. Recent Supreme Court rulings have confirmed that a guarantor company is not a party to the lease and cannot bypass the court process to remove a tenant. An unpaid rent month is a debt-collection matter, not an immediate eviction. The landlord still needs to file a court action to evict you, which is a slow and costly process.
- Credit Reporting: If your guarantor company is one that uses credit bureau data (like Orico, Jaccs, or Aplus), defaulting on payments can be reported to Japan's main credit bureaus (CIC and JICC). This can negatively impact your ability to get future credit cards or loans in Japan.
What to do if you face improper screening or discrimination?
Unfortunately, improper rejection of applicants based on nationality, age, or welfare status is a documented problem in Japan's rental market. This includes:
- Blanket denial based on foreign nationality.
- Denial of welfare recipients, despite welfare benefits being a legitimate source of income.
- Denial based on disability, which may violate the Act on the Elimination of Discrimination Against Persons with Disabilities.
If you believe you have been improperly denied housing, you can contact the following organizations for consultation:
- Ministry of Land, Infrastructure, Transport and Tourism Housing Consultation Hotline: 0570-040-777
- Legal Affairs Bureau / Human Rights Consultation: For issues related to discrimination based on nationality or disability
- Housing Support Council for Persons with Housing Insecurity: Established in each prefecture for individual consultations
Conclusion
For most foreign residents seeking to rent an apartment in Japan, a guarantor company will be the standard and often the only viable option. While it involves additional fees and a screening process, it removes the significant hurdle of finding a personal guarantor. Understanding the costs, required documents, and the implications of guarantor company involvement will equip you for a more successful apartment search. Always read your contracts carefully and don't hesitate to seek clarification from your real estate agent or property manager.
FAQ
Q1: Is a guarantor legally required to rent an apartment in Japan?
No, technically, a guarantor (either personal or company) is not a legal requirement set by the government. However, it is a contractual requirement imposed by the vast majority of landlords and property management companies in Japan, making it a practical necessity for securing a rental apartment clea.rent.
Q2: Can I choose my own guarantor company?
Typically, no. The guarantor company you use is usually designated by the landlord or property management company that handles the property. Real estate brokerages often have agency contracts with specific guarantor companies, meaning you'll go through their assigned firm.
Q3: What if my visa expires mid-lease?
Guarantor companies often require your residence card to be valid for the entire lease term (usually two years). If your visa expires mid-lease, it can lead to rejection during the screening process or complications during renewal. It's crucial to have a long enough visa or a clear plan for renewal when applying.
Q4: Can a guarantor company evict me if I don't pay rent?
No, a guarantor company cannot directly evict you. While they will pursue you for unpaid rent if they've paid the landlord on your behalf, they are not a party to your lease agreement. Only the landlord can initiate eviction proceedings through the court system, which is a separate and often lengthy process.
Q5: Does having a guarantor company affect my credit score in Japan?
If your guarantor company is one that uses credit bureau data (like Orico, Jaccs, or Aplus), defaulting on payments can be reported to Japan's main credit bureaus (CIC and JICC). This can negatively impact your credit score and future ability to obtain credit cards or loans in Japan.
