Japan Naturalization Documents Checklist (2026)

A Japan naturalization documents list combines prescribed forms, civil-status records, residence evidence, and detailed financial, tax, and social-insurance paperwork. Your exact 帰化申請 必要書類 (kika shinsei hitsuyō shorui) will depend on your nationality, family history, work, assets, and household, so use this checklist to prepare for confirmation by the Legal Affairs Bureau.

This guide uses published examples from Gifu and Hiroshima. They are preparation references, not a universal checklist: your nationality, circumstances and the bureau responsible for your address determine the final requirements. Gifu Legal Affairs Bureau. Hiroshima Legal Affairs Bureau.

Start with an individualized document list

The Legal Affairs Bureau checks application and supporting documents at the initial consultation. Because requirements differ between applicants, an officer may request documents beyond the published checklist or ask you to correct incomplete paperwork before the next consultation Gifu Legal Affairs Bureau.

Bring the naturalization consultation questionnaire and the relevant document confirmation sheet. Mark the documents already collected and arrange them in the order shown on that sheet.

Nationality and family-status documents

There is no single worldwide civil-document package. Home-country authorities use different systems, and required documents differ between applicants. Use the Legal Affairs Bureau’s published confirmation sheet and confirm whether additional documents are required for your circumstances rather than substituting documents merely because they have similar English titles.

The Gifu checklist for “other nationalities” calls for proof of nationality and the civil records relevant to the applicant’s circumstances. These can include:

• Nationality certificate
• Birth certificate
• Marriage or divorce certificate, if applicable
• A family list showing the applicant, parents, and siblings
• Siblings’ birth certificates if the family list omits them
• Records concerning adoption, recognition of parentage, or custody
• Parents’ marriage or divorce records
• Children’s birth certificates

Check whether a nationality certificate has an expiry date. Where it does, the bureau advises obtaining it when the officer instructs you to do so.

Copies of every passport are also required, including expired passports. Copy all used pages containing entry, departure, or other stamps; unused pages may be omitted Gifu Legal Affairs Bureau.

Japanese family records may also be relevant. Examples include a Japanese family register for a current or former spouse, parent, adoptive parent, or child who is or was Japanese, and records showing a relative’s naturalization or acquisition of nationality.

Residence and driving records

Prepare a residence certificate for the entire household showing the required identity, residence-status, residence-card, and address-history details. The certificate should omit the My Number and resident-record code; if it does not show the full relevant address history, obtain deleted residence records as well Hiroshima Legal Affairs Bureau.

Also prepare copies of both sides of the residence card. Drivers need a five-year driving record certificate issued within two months, copies of both sides of the licence, and a driving-history certificate if a licence expired or was revoked. Hiroshima Legal Affairs Bureau.

Financial, income, tax, and insurance evidence

Support the application with financial records for the applicant. If a spouse, common-law partner, or another person shares the same livelihood, the bureau also requires relevant documents for that person Hiroshima Legal Affairs Bureau.

Hiroshima’s published income and asset examples include:

• Employees: employment certificate and the latest month’s salary certificate or payslip
• Sole proprietors: applicable permits or licences
• Company officers: corporate registration and applicable permits
• Property owners: land, building, or condominium registration certificates
• Savings holders: current balance certificates, copies of passbooks excluding unused pages, and printed web-passbook transaction histories
• Tenants: lease or occupancy approval
• Other situations: overseas remittance records, pension evidence, or benefit statements

Example from Hiroshima: Tax documents depend on employment and filing status. For an employee without a tax-return obligation, the published checklist includes five years of resident-tax assessment or non-assessment certificates, five years of payment or non-assessment certificates, the latest year’s withholding slip, and evidence of timely payment where tax was not specially collected through payroll. Hiroshima Legal Affairs Bureau.

Example from Hiroshima: Applicants required to file a return need additional income-tax payment certificates for the latest three years and a copy of the latest year’s return. Sole proprietors and company officers must provide further business or corporate tax records, with the required periods varying by document. Hiroshima Legal Affairs Bureau.

Collect the health-insurance qualification information and payment evidence specified by your bureau. Confirm whose household records are needed, the period each document must cover, and whether dated receipts or bank transactions are needed to show when payments were made.

Before submitting copies, ask which personal identifiers must be masked and which details must remain visible. Keep the documents and payment dates legible.

Originals, copies, paper size, and binding

For documents submitted with the application, prepare the original and a duplicate consisting of an unscaled copy of the original. Prepare all items in two sets, including two photographs. For passports, driving licences, and other items whose originals cannot be submitted, prepare two copies and bring the original to the consultation Gifu Legal Affairs Bureau.

Use A4 paper for copies, leave approximately three centimetres of space on the left, and organize the papers for left-side binding. Passport spreads should be copied vertically with the same left margin. Tokyo Legal Affairs Bureau.

Do not enlarge or reduce copies. Before attending, place the forms and attachments in the order listed on the bureau’s confirmation sheet rather than grouping them according to your own filing system.

Translating foreign-language civil documents

Every foreign-language document needs a complete A4 translation. Partial translations are not accepted, and each translation must state the translator’s address, name, and translation date Gifu Legal Affairs Bureau.

A professional translator is not mandatory under the published checklist. Anyone capable of translating accurately—including the applicant—may prepare the translation.

Follow your bureau’s instructions for Japanese spellings. Gifu asks for names in katakana on translations. Keep spellings consistent across the forms, translations and supporting records. Gifu Legal Affairs Bureau.

Practical collection order

Use this order to reduce avoidable rework:

1. Complete the consultation questionnaire.
2. Mark the documents already collected on the responsible bureau’s published confirmation sheet and confirm whether additional documents are required.
3. Collect family, residence, employment, asset, tax, and insurance records.
4. Translate every foreign-language document in full.
5. Make unscaled A4 copies, check margins, and arrange both sets in checklist order.

If a required document cannot be obtained, do not silently replace or omit it. Explain the circumstances to the Legal Affairs Bureau officer during the consultation so the issue can be reviewed.
