Complete Guide to Credit Information (CIC/JICC) and Personal Data Handling When Applying for Rental Housing

What is Credit Information? Its Relationship to Rental Screening

When applying for a rental property, many people feel anxious about the word "screening." Behind the scenes of that screening process, credit information plays a crucial role.

Credit information is data that records contract and payment history for credit cards, loans, and similar financial products. Financial institutions and guarantee companies reference this information to assess an applicant's repayment ability and creditworthiness.

In rental contracts, rent guarantee companies typically review credit information during their screening process. They use this information to confirm whether monthly rent will be paid reliably and to check for any past delinquencies or defaults.

In recent years, properties increasingly require rent guarantee company enrollment in addition to a joint guarantor. As of 2026, rent guarantee company usage has expanded to nearly 90% of the rental market, and the contents of credit information increasingly directly impact whether rental screening applications are approved or rejected.

Differences Between CIC and JICC and Their Roles

Japan has multiple credit information bureaus, but the two most relevant to rental screening are CIC and JICC.

CIC

CIC is a credit information bureau established through joint investment by credit card companies. It primarily manages information related to credit cards and installment purchase plans.

• •Information managed: Credit card payment history, cash advance usage, installment payments for mobile phone devices, etc.
• •Member companies: Credit card companies, consumer finance companies, mobile carriers, etc.
• •Delinquency record retention period: 5 years after delinquency is resolved

JICC (Japan Credit Information Organization)

JICC is a credit information bureau to which consumer finance companies and credit companies belong. It records information about loan and consumer finance usage.

• •Information managed: Consumer loans, cash advances, credit contract status
• •Member companies: Consumer finance companies, credit companies, guarantee companies, etc.
• •Delinquency record retention period: 1 year after delinquency is resolved (shorter than CIC)

Relationship with Rent Guarantee Companies

Most rent guarantee companies are members of CIC, JICC, or maintain independent assessment databases (such as LICC or CGO). They review applicant information, check past delinquency records and current borrowing status, then make a decision on whether to provide the guarantee.

Specific Information Reviewed During Rental Screening

Credit information bureau records are divided into three main categories.

1. Contract Information

Contract details for credit cards, loans, and similar products are recorded.

• •Name of company, contract date, and contract amount
• •Payment balance
• •Credit limit

2. Payment Status (Payment History)

Monthly payment status is recorded. This is the most emphasized aspect in rental screening.

• •Whether payments are being made on time
• •Whether there is delinquency (61+ days or 3+ months overdue)
• •Whether delinquency has been resolved

3. Accident Information (Blacklist Records)

Major issues, also called financial accidents, are recorded.

• •Extended delinquency (3+ months unpaid)
• •Debt restructuring (bankruptcy, debt negotiation, personal rehabilitation)
• •Forced termination (unilateral termination by a card company)

While accident information is recorded, the risk of rejection in rent guarantee company screening increases significantly. The retention period varies by bureau, but typically ranges from 5–7 years.

Personal Data Handling and Consent

Rental application forms always include a personal data handling consent form. It is important to review the content before signing. For detailed information on personal information protection in rental applications, see also [Latest Rules on Rental Contracts and Personal Data Protection [2026 Edition]](/columns/contract-personal-info-protection-2026).

Main Matters Requiring Consent

① Consent to Credit Information Bureau Inquiry The form specifies that you consent to inquiries to credit information bureaus such as CIC or JICC. Without this consent, inquiries cannot be made.

② Purpose of Personal Data Use The form clearly states the purposes for which collected personal data will be used. Main uses include screening, contract management, and renewal procedures.

③ Provision to Third Parties This covers consent for information sharing among real estate agencies, guarantee companies, property management companies, and owners.

Rights Under the Personal Information Protection Act

Applicants have the following rights:

• •Right to request disclosure: The right to request disclosure of personal data held about you
• •Right to request correction or deletion: The right to request correction or deletion of incorrect information
• •Right to request cessation of use: The right to request that inappropriate use be stopped

If you have questions or concerns, confirm them with the real estate agency or guarantee company before applying.

Advance Preparation to Prevent Application Rejection

Even if there are issues with your credit information, taking steps in advance can improve the likelihood of passing screening.

Check Your Credit Information Before Applying

Both CIC and JICC offer personal disclosure services to applicants. By checking your own credit information before applying, you can determine whether any issues exist.

• •CIC: Disclosure available online, by mail, or in person (fee approximately ¥500–¥1,000)
• •JICC: You can request disclosure through a smartphone app

Clear Any Delinquencies Before Applying

If you currently have any outstanding delinquencies, your first priority should be to make full repayment and resolve them. Applying while delinquent will almost certainly result in rejection.

Secure a Joint Guarantor

If you are concerned about your credit information, securing a family member as a joint guarantor may make it easier to pass screening. However, some properties requiring mandatory rent guarantee company enrollment may not be able to accommodate this approach.

Choose Properties and Guarantee Companies Without Credit Concerns

Screening criteria vary by guarantee company. One option is to select properties that use guarantee companies with independent screening that do not reference CIC or JICC (such as those affiliated with LICC). A real estate agency can sometimes recommend appropriate properties.

Summary

Credit information inquiry during rental applications is a legitimate process for confirming your rent payment ability. Understanding the differences between CIC and JICC, and checking your own credit information status in advance, is the shortcut to smooth rental screening.

Regarding personal data handling, it is important to thoroughly review the consent form and sign only after you understand it. Do not hesitate to ask the real estate agency or guarantee company about any unclear points.

Even if you have concerns about screening, advance preparation and selecting appropriate properties can improve your situation. Consult with trustworthy real estate agency staff and start your new life with peace of mind.
