Why Did the Rent Guarantor Company Reject My Application?

When renting a home in Japan, an application may pass the real-estate agency's initial review but stop at the screening by a rent guarantor company, called 家賃債務保証会社 or simply 保証会社. This result does not necessarily mean that the landlord considers you a bad tenant, nor does it mean that every other property will reject you.

The hardest part is that guarantor companies generally notify the real-estate company and do not reveal their detailed criteria or the specific reason. JID and Zenhoren both state on their official websites that they may decline to provide a guarantee and will not disclose screening details or reasons. The practical response is therefore not to guess at a secret “credit score,” but to review every part of the application that can be checked.

Quick answer: why might an application be rejected?

These are review directions, not an official checklist used by every company. Each guarantor, landlord, property, and guarantee product may have different conditions, and applicants are normally not told the internal scoring formula.

Distinguish the three screening stages

A rental application may pass through a real-estate agency, guarantor company, property manager, and landlord. They may exchange information, but they are not the same organization and do not necessarily reach the same decision.

The phrase “審査に落ちました” does not identify which stage failed. Ask the agent: 保証会社の審査ですか、それとも貸主・管理会社の審査ですか — was it the guarantor company's screening, or the landlord's or property manager's screening?

What does a rent guarantor commonly verify?

JID's official information lists suitable ability to pay rent, an application without problems such as false statements, and submission of required documents among its application conditions. Its guidance for foreign residents also describes identification, evidence supporting payment, and confirmation by SMS or telephone. Zenhoren says incomplete documents or content checks may lead it to contact the applicant, joint guarantor, or emergency contact.

• The identity of the person named on the lease.

• The current address and any relevant residence history.

• Current employment, school, or living status.

• Income, financial support, or another basis for paying rent.

• The people who will actually occupy the property.

• Phone numbers for the applicant and emergency contact.

• Consistency among the form, supporting documents, and verification answers.

Do not turn this list into a claim that every company uses the same income ratio or scoring scale. Additional documents may be requested depending on the applicant, contract type, property, and guarantee product.

1. Ability to pay the rent is not clearly supported

This is not merely a calculation of rent divided by salary. The reviewer may need to understand whether the funding is stable, whether a newly hired applicant has started work, whether income on the form means base salary or includes allowances, and who will pay when the applicant is a student or dependent.

A newly employed applicant may have a weak file if only a salary figure is written without an employment contract, certificate of employment, or proof of the start date. A self-employed applicant may struggle if a bank balance is submitted without explaining cash flow. Someone supported by family should identify the supporter and relationship instead of leaving the reviewer to infer them.

• State income using the period and category requested on the form.

• Distinguish monthly salary, annual salary, revenue, and income after expenses.

• If no payslip exists yet, provide an appropriate contract or employment certificate.

• If someone supports you, use the same name, relationship, and funding explanation everywhere.

• Choose rent with a reasonable buffer against the actual payment source.

• Do not add uncertain bonuses merely to make the application look stronger.

Paying several months in advance may help explain finances in some cases, but it does not automatically replace guarantor screening. Only use this option when the agency confirms that both the landlord and guarantor accept it.

2. Information conflicts across documents

One small difference does not necessarily cause rejection, but several inconsistencies can make an application impossible to verify. Examples include an abbreviated employer name that differs from the contract, an outdated address on the residence card, income on the form that differs from the evidence, or a changed number of occupants after submission.

• Write your name exactly as shown on identification.

• Use one consistent employer name and workplace address.

• Check the employment start date, contract type, and income amount.

• Declare every spouse, child, or other person who will live there.

• Explain in advance if an address document is being updated.

• Do not let an agent enter a number you have not confirmed.

If you discover an error after submission, tell the agent immediately. Sending a second version through another channel may create another conflict; let the receiving agency update it through the proper process.

3. Verification calls or messages were not completed

Some companies may call the applicant, workplace, or emergency contact. JID states that it may confirm details by SMS or phone and may contact the workplace. Zenhoren also describes possible contact with people listed in the application.

• Answer unfamiliar numbers during the screening period.

• Check voicemail, SMS, and spam folders.

• Give answers that match the submitted application.

• Alert the workplace if an employment confirmation call may arrive.

• Obtain the emergency contact's consent before listing them.

• Tell the agent in advance if language support is required.

Missing one call does not necessarily cause an immediate rejection, but repeated failed contact or answers that differ from the application may stop the process. Do not ask another person to impersonate you; if your Japanese is limited, ask beforehand about an acceptable interpreter arrangement.

4. Documents are missing, unreadable, expired, or the wrong type

Documents are not collected merely to reach a page count. The reviewer must be able to read the information and connect it to the applicant's current status. For foreign residents, the residence card is often important; Zenhoren publicly states that foreign nationals residing in Japan may apply and must submit a copy of the residence card.

• Photograph both sides when both are requested.

• Do not hide the name, address, period of stay, or status that must be verified.

• Use a certificate of employment with an appropriate issue date.

• Include relevant employment-contract pages showing salary and term.

• Clarify which document proves savings or a financial supporter.

• Do not submit expired papers or images that are too blurred to read.

Do not send more sensitive material than necessary on your own initiative. Ask the agent exactly what the guarantor requires and mask fields only according to instructions, such as certain information on a Japanese health-insurance document.

5. The emergency contact is ineligible or cannot be verified

An emergency contact is not necessarily responsible for paying the tenant's debt, but may serve as a contact when the tenant cannot be reached. Requirements concerning relationship, age, residence, or language vary. JID, for example, publishes a general requirement for a consenting relative within a specified degree who lives in a separate household in Japan.

• Ask about eligibility before listing a friend.

• Use an active number that can receive calls.

• Make sure the person knows they have been listed.

• Use one consistent description of the relationship.

• Do not describe the same person differently on separate forms.

If you have no relative in Japan, tell the agent from the start. Do not list someone who has not agreed or a phone number that does not work merely to complete a required field.

6. The property or guarantee product is not eligible

Not every rejection reflects the applicant's personal finances. The intended use may be outside the guarantee's coverage, the asset type may be excluded, the named applicant may not fit the product, or the property may accept only a guarantor selected by the management company.

JID states that certain uses, including 民泊, and certain property types may be ineligible. Zenhoren likewise notes that applications remain subject to its own screening. Changing the way income is presented will not solve a case where the guarantee product does not cover the property or use in the first place.

Are foreign nationals rejected simply because of nationality?

You cannot determine the reason from a declined guarantee alone. JID publicly states that it does not decide based on occupation or nationality, although property-specific conditions may differ. Zenhoren also says foreign residents living in Japan may apply with a residence-card copy.

However, a foreign resident's file may require more verification concerning residence status, period of stay, language for communication, work, school, and emergency contacts. The practical question is often whether the reviewer can verify the information and payment plan, so do not automatically conclude that every rejection is caused by nationality.

What should you do immediately after rejection?

Do not submit the same file for several properties on the same day before identifying which screening stage failed. Ask the agent to confirm what they are allowed to share, then review every correctable item.

• Confirm whether the rejecting party was the 保証会社, landlord, or property manager.

• Ask whether documents are still missing or the result is final.

• Recheck income, employment, address, and occupants.

• Look for any missed call or SMS.

• Confirm that the emergency contact received and answered calls.

• Ask whether the property accepts another guarantor company.

• Choose another property only after identifying what must change.

The agent may not know the internal reason. Do not pressure them to promise an explanation without evidence. A more useful question is: “Given my current situation, what should I add next time, and which properties accept this type of application?”

While you wait for the agent to come back to you, you can compare the conditions attached to each property so the next application targets a better fit.

Can the same guarantor reconsider the application?

You may ask, but do not assume that a formal appeal always exists. If the case is merely on hold because a document is missing or contact failed, the agent may be able to add information and continue. If it is already 不承認, the company may not reconsider immediately and may still withhold the reason.

Reapply only when something material has changed, such as correcting false information, providing requested documents, or updating employment status. Submitting the same file again with different wording usually provides no new basis for a decision.

Can you switch to another guarantor company?

This depends on the property and the agreements among the landlord, manager, and guarantor companies. Tenants generally cannot choose any 保証会社 on the market. Some properties have a second option; others accept only one designated provider.

If switching is allowed, the new application must still be truthful and consistent. Do not conceal an earlier application if the form or agent asks about it. A different company has its own criteria, so one rejection neither guarantees another rejection nor approval.

Prepare again according to employment status

This table is a checklist for speaking with the agent, not a universal required-document list. Submit only documents relevant to the form and the particular guarantor's request.

What not to do

• State income above the documentary amount because it seems more likely to pass.

• Change occupants or intended use after submission without notice.

• Ask another person to answer the phone while pretending to be the applicant.

• List an emergency contact who has not agreed.

• Submit blurred documents and wait for the reviewer to ask again.

• Transfer a holding payment because someone promises guaranteed approval.

• Apply repeatedly for properties without correcting the same weak point.

• Assume that several months of advance rent always replaces a 保証会社.

A strong application is not the one that looks wealthiest. It is the one with truthful, explainable information, suitable supporting documents, and people who can confirm the details.

Frequently asked questions

Will the guarantor company disclose the reason for rejection?

Usually not. JID and Zenhoren both state that screening details or reasons are not disclosed. The result is generally delivered through the real-estate agency or property manager.

Can I rent another property after one guarantor rejects me?

Possibly. Another property may use a different guarantor or conditions. Review and correct the checkable weaknesses before applying rather than sending the identical file again.

Will one missed phone call cause immediate failure?

That cannot be assumed. Call back as instructed or notify the agent promptly. Repeated inability to make contact or answers inconsistent with the application are more serious concerns.

What if I have savings but low income?

Savings may support the application, but acceptance depends on the company and property. Ask what evidence of payment resources is accepted and whether a financial supporter is needed.

Must an emergency contact pay on my behalf?

Do not confuse an emergency contact with a joint guarantor. Responsibility depends on the role and the documents signed, so read the exact title of each form before agreeing.

What should I prepare for the next application?

Create one definitive information sheet covering your name, address, employment, start date, income, occupants, and emergency contact. Match every field to the documents, alert anyone who may receive a call, and ask the agent to filter properties with a suitable guarantee arrangement.
