Required Documents for the Japanese Spouse Visa by Case Type [Explained by a Licensed Immigration Specialist]

The status of residence "Spouse or Child of Japanese National" is required for foreign nationals married to Japanese citizens who wish to live in Japan. Required documents vary depending on your situation, so preparing for the right case is the first step toward approval. This article organizes the requirements into three application patterns based on official information from the Immigration Services Agency of Japan.

Three Application Patterns — Identify Your Case First

Before gathering documents, confirm which application type applies to your situation.

Pattern ①: Sponsoring a Spouse from Overseas

To bring your foreign national spouse to Japan from abroad, the Japanese spouse living in Japan must first apply for a Certificate of Eligibility (COE) at a regional immigration office. Once the COE is issued, it is sent to the spouse abroad, who then applies for a visa at a Japanese embassy or consulate in their country.

What Examiners Look For

Immigration examiners focus on two key areas:

1. Authenticity of the marriage: Is this a genuine marriage, not a sham?
2. Financial stability in Japan: Can the couple sustain their life in Japan economically?

Understanding that documents are gathered to prove these two points helps clarify what to prepare most thoroughly.

Main Required Documents

The Immigration Services Agency requires the following documents (also refer to the official checklist):

• Application for Certificate of Eligibility
• Passport-style photo (4cm × 3cm, taken within the past 3 months, no hat, plain background)
• Japanese spouse's family register (koseki tohon — full record showing the marriage)
• Marriage certificate issued by the foreign spouse's home country (with Japanese translation if in a foreign language)
• Documents proving financial support (e.g., municipal tax certificate, tax payment certificate)
• Letter of guarantee from the Japanese spouse
• Residence certificate (jumin-hyo) of the Japanese spouse (listing all household members, with My Number omitted)
• Questionnaire (downloadable from the Immigration Services Agency website; answer all questions honestly)
• Materials showing the couple's interaction (2–3 casual photos, SNS records, call history, etc.)
• Return envelope (for registered mail)

Common Reasons for Rejection in Practice

The questionnaire is a particularly important document. It asks about how you met, how long you dated, and how you communicate. Examiners use it to check for inconsistencies in the application. Writing your marriage story in detail and honestly helps build trust with the examiner.

Regarding proof of financial support: if you cannot obtain a municipal tax certificate due to a recent move or job change, you may substitute a bank passbook copy or a letter of employment offer. If using a certificate of bank balance, it is important to show a consistent savings history — not a one-time deposit — through the passbook transaction record.

Pattern ②: Changing Status of Residence While Already in Japan

This applies when someone in Japan on a student or work visa marries a Japanese national and wants to switch to a Spouse Visa. The applicant applies in person at the immigration office.

Main Required Documents

• Application to Change Status of Residence
• Passport-style photo (not required for those under 16)
• Japanese spouse's family register (issued within the past 3 months)
• Marriage certificate (with Japanese translation if in a foreign language)
• Documents proving financial support
• Letter of guarantee
• Residence certificate (listing all household members, My Number omitted, issued within 3 months)
• Questionnaire
• Materials showing the couple's interaction
• Passport (must be presented)
• Residence card (must be presented)

Pattern ③: Renewing an Existing Japanese Spouse Visa

This applies when you already hold a Japanese Spouse Visa and need to renew it to continue staying in Japan.

Main Required Documents

• Application to Extend Period of Stay
• Passport-style photo (not required for those under 16)
• Japanese spouse's family register (showing the marriage)
• Documents proving financial support
• Letter of guarantee
• Residence certificate (listing all household members, My Number omitted)
• Passport (must be presented)
• Residence card (must be presented)

The renewal review reconfirms whether the marriage is ongoing and whether life in Japan is financially stable. Whether the period of stay is extended to 3 or 5 years is determined by a comprehensive assessment of the length of marriage, co-habitation status, income, and tax and social insurance payment history.

Rules That Apply to All Cases

• All certificates issued in Japan must have been issued within 3 months of the application date
• Japanese translations must be attached to all foreign-language documents (including the translator's name and address)
• Documents are generally not returned (request original return at time of submission if needed)
• Additional materials may be requested during review — be prepared to respond promptly
• Incomplete applications will face significant delays or unfavorable decisions

Summary

Regardless of which pattern applies, the core of every application is demonstrating the authenticity of the marriage and financial stability in Japan through thorough documentation.
