This is the MAIN form of the whole application — Application for Certificate of Eligibility (COE) (在留資格認定証明書交付申請書), issued by the Immigration Services Agency. Every other document is an attachment to it; without it you cannot file at all.
What it must show
- Use the LATEST official version — old versions may be rejected
- Fill it in Japanese, clearly, with no corrections
- Attach the photo and sign in the designated boxes
- Some procedures have a section for your COMPANY / sponsor to fill in — ask them to complete it
Where to get it
Download the latest version from the Immigration Services Agency website, or pick it up at an Immigration counter. IIKANZI VISA can also fill it in for you and export a print-ready PDF.
How to get it
- Option 1: download the blank form from the Agency site and fill it in by hand
- Option 2: use IIKANZI VISA — answer step by step, the app fills the right boxes and exports a PDF
- Print it, sign, attach the photo, and submit together with the other documents
Cost & time
The form itself is free. A fee (paid with a 収入印紙 revenue stamp) applies only when your application is APPROVED — check the Agency's current fee notice.
Notes
Each procedure uses a different form — submitting the wrong one gets your application returned. Check the form name above before printing.

What this document is
These questions decide (1) which income-proof documents the sponsor must gather and (2) whether you must prepare a return envelope yourself. A wrong answer means wasted trips or a returned application.
What it must show
- Tax certificates key off 1 January (賦課期日). The city issues 課税証明書・納税証明書 only to people registered as residents on 1 January of that fiscal year. Arriving mid-year means going home empty-handed.
- What to submit instead. The last 2-3 payslips (給与明細) plus a certificate of employment (在職証明書). Add a short written reason (理由書) stating you arrived recently so the city cannot issue them.
- What Immigration says. The official page states: 「入国後間もない場合や転居等により、お住まいの区役所・市役所・役場から発行されない場合は、最寄りの地方出入国在留管理官署にお問い合わせ下さい」— newcomers are an anticipated case, not an automatic refusal.
- Who files. The return envelope only exists so the Bureau can post the COE. When a law / immigration office files as your 申請取次, they use an envelope addressed to their own office. Since 17 Mar 2023 you may also receive the COE by e-mail (電子交付), which removes the envelope entirely.
Notes
If you are unsure, leave it blank — the app then shows the FULL set, which is the safe side: extra papers are accepted, missing ones get you sent home.

The gensen is issued by the company after 年末調整 (year-end tax adjustment), around December / early the next year. ➊ You've worked through at least one year-end adjustment (year 2025 or earlier): you HAVE a gensen (令和7年分, 2025 income). ➋ Just arrived / just started working this year: you have NO gensen yet since you haven't been through a year-end adjustment → the first one comes out in around December 2026 – early 2027; while waiting, submit your last 3 MONTHS' PAYSLIPS instead to prove income.

The last 3 MONTHS' payslips (給与明細, kyuuyo-meisai) of the SPONSOR (you) — proving your CURRENT income. Especially needed when you're NEW to Japan / just started working and don't yet have a full year of income, so you don't yet have income & tax certificates (課税/納税証明書).

- Clearly show the recipient's name + pay month + total received (支給額)
- The company-issued version (paper or printed from the payroll system)

How to get it
- Request or print the payslips for the last 3 months
- Photograph each one clearly — one image per month (3 slots)
Cost & time
Free (issued by the company).
Notes
If you've worked in Japan for LESS than a year: you don't have 課税/納税証明書 yet → submit 3 months' payslips INSTEAD to prove income. If you already have the tax certificates, this is a supporting document for extra assurance.
Income certificateCertificate of annual INCOME + municipal (resident) tax (課税証明書, kazei-shōmeisho). The version to use now is Reiwa 7 nendo · 2024 income.See detailsWhat this document is
Certificate of annual INCOME + municipal (resident) tax (課税証明書, kazei-shōmeisho). The version to use now is Reiwa 7 nendo · 2024 income.
What it must show
- Shows total annual income + municipal tax amount
- Request exactly the Reiwa 7 nendo · 2024 income version
Where to get it
Apply at the CITY HALL (shiyakusho) where you were REGISTERED AS A RESIDENT on 1/1/2025. If you lived in a different city on that date, you must apply at that former city.
How to get it
- Bring your residence card (or My Number card) to the city hall
- Request the Reiwa 7 nendo · 2024 income version
- With a My Number card you can also get it at a kiosk in a convenience store
Cost & time
About 300 yen per copy. Issued the same day.
Notes
Why NOT a newer year (income 2025): that year's municipal tax is paid in several installments and is only FULLY paid around early 2027 — until then the tax-payment certificate is not “clean”. So for now, get all 3 documents consistently for the 2024 income year.

- Clearly ask for the “fully paid, no arrears” version
Cost & time
About 300 yen per copy. Issued the same day.
Notes
If you have arrears or haven't finished paying, you can't get a “clean” certificate — that's why you use an income year for which tax is already fully paid.
Employment ContractNeeded only if the SPONSOR (you) just changed jobs: the NEW company's employment contract (雇用契約書) + the FORMER company's separation slip (離職票…See detailsWhat this document is

How to get it

The Tokutei category is temporarily EXEMPT; but the family-reunification category REQUIRES it — double-check with the Embassy / hospital. The hospital list may be updated.

An envelope for the Bureau to MAIL BACK the Certificate of Eligibility (COE) after review. It is only the DELIVERY channel — whoever receives the COE prepares the envelope.
What it must show
- You file in person and want it posted → NEEDED. A standard (定形) envelope, your name and Japanese address written clearly, with a registered-mail (簡易書留) stamp.
- A law / immigration office files as your 申請取次 → YOU need nothing. The Bureau returns the COE to the filer, so the office uses an envelope addressed to itself (or collects at the counter). Just confirm with them once.
- Receiving the COE by e-mail (電子交付, since 17 Mar 2023) → no envelope at all. You must register on the online system first, then hand in 「(窓口申請)在留資格認定証明書電子交付希望申出書」 at the counter. Filing online: pick 受領方法 = メール.
Where to get it
Buy the envelope + stamp at the post office (yuubinkyoku) or a convenience store.
How to get it
- First ask: are you filing yourself, or is an office filing for you? — if the office files, STOP, buy nothing
- Filing yourself: buy one ordinary-format envelope
- Write your (the sponsor's) home address in the recipient box
- At the post office, buy & affix a registered-mail stamp (say: 'kani-kakitome')
- Include it with the document set when submitting
Cost & time
A registered-mail stamp (kani-kakitome) is about 400+ yen (ask the post office for the exact amount).
Notes
Stamp rates change with postal prices and vary by local Bureau — ask a postal clerk. If you already submitted an envelope and later switch to e-mail delivery, the Bureau returns the envelope to you.
Information for the formThe remaining form fields you fill in yourself: current address, phone number, planned timing, how living costs are paid (shiben-houhou)…See detailsWhat this document is

What it must show

- The phone number must be reachable
How to get it
- The app will ask each field simply (later version)
- Check consistency with the documents you've submitted
Notes
Inconsistent information across documents easily leads to extra questions from the Bureau / a longer review.
Part-time work permit (28h)If your status does not allow work — for example 家族滞在 (Dependent) or 留学 (Student) — you must get permission from the Immigration Bureau before taking…See detailsWhat this document is
If your status does not allow work — for example 家族滞在 (Dependent) or 留学 (Student) — you must get permission from the Immigration Bureau before taking a part-time job. That permission is called 資格外活動許可.
What it must show
- NEEDED: a 家族滞在 (Dependent) holder who wants a part-time job
- NOT needed: a status that already allows work (Engineer, Tokutei Ginou…)
- NOT needed: a residence card marked 就労制限なし (no work restriction)
Where to get it
The Immigration Bureau (入国管理局) for your area — submit it at the same time as your main application, so you only go once.
How to get it
- Tick “I want to apply for permission to work part-time” on this step
- Enter the planned workplace (leave blank if you don't have one yet)
- Download the 資格外活動許可申請書 the app filled in for you
- Submit it TOGETHER with your main application — free of charge
Cost & time
Free. It is reviewed alongside your main application, so the result usually comes at the same time.
Notes
Limits: up to 28 hours a week (students may work up to 8 hours a day during long school holidays). Adult-entertainment work (風俗) is NOT allowed. Working over the limit will hurt your next extension or visa application.
