What documents do you actually need to work in Japan?

Documents in this process fall into two broad types: documents you control and gather yourself, and documents that depend on external parties — your employer, your sending organization, or government agencies.

The documents you control are ones you can start gathering now, regardless of whether you have an employer or intermediary lined up. The documents others provide come later, but understanding what they should look like helps you evaluate whether the people you work with are operating legitimately.

A critical warning: a legitimate process will never require you to hand over original documents and leave them in someone else's keeping for extended periods. Your passport, ID card, and academic certificates remain in your possession. Any operator who says they need to hold your documents 'for safekeeping' is operating outside acceptable norms.

Passport: Your passport must be valid for the duration of your intended stay in Japan. If yours is near expiry, renew it before starting any formal process. Most visa applications require at least 6 months of validity beyond your intended entry date. Keep both the current passport and any expired passports — previous visas and travel history are sometimes requested.

National ID card (CCCD in Vietnam): Required for most formal applications and sending organization registrations. Ensure it is not expired.

Birth certificate: Usually required for identification purposes and, in some cases, for family-related documentation. Obtain an officially certified copy from your local authority. Some processes require a notarized translation — check the specific requirement early.

Household registration document (hộ khẩu): Required in many Vietnam-originating application processes. Get a certified copy from your local government office.

Highest education certificate and transcripts: Even for roles that do not require formal education, your certificate is often required as part of the standard application file. If your original certificate is difficult to obtain, start this process early.

Work history records: These may include employment contracts from previous employers, social insurance book (sổ bảo hiểm xã hội), or employer reference letters. They help demonstrate consistency of employment and confirm the kind of work you have done.

Health certificate: A standard medical exam from a recognized facility confirming you do not have conditions that would prevent safe employment. Requirements vary slightly by destination and employer, but a general health check with chest X-ray, blood tests, and basic physical assessment is typically expected. Use an approved facility — your sending organization should be able to advise on recognized clinics.

JLPT certificate: For most SSW roles, you need a Japanese Language Proficiency Test certificate at N4 level or above. Some employers in lower-communication roles may accept candidates still in preparation, but the certificate is expected before visa issuance. Register for JLPT exams well in advance — test dates are limited and popular sessions fill up.

Sector skills assessment certificate: The SSW visa requires passing a Japan-recognized skills evaluation test specific to your sector. For food production, manufacturing, agriculture, and hospitality, separate tests exist. These tests are administered at authorized sites, including in Vietnam. Scheduling early is important because available test slots are not unlimited. Passing both the language test and the skills test is required before a visa application can proceed.

Note on substitutes: In some cases, holding a Level 2 or higher technical skills certificate in a related field may substitute for the sector skills test. This varies by sector and employer. If you hold a relevant Vietnamese professional certificate, ask specifically whether it is recognized under the current SSW framework.

Labor contract (労働条件通知書 / 雇用契約書): Your employer in Japan must provide a written labor contract before you sign anything and before you depart. It must specify your role, hours, wage, deductions, work location, and contract duration in a language you can understand. If you are shown a contract only in Japanese with no translation, that is a problem. If the wage on the contract differs from what was verbally promised, do not proceed.

Visa sponsorship documentation: Your employer or the registered accepting organization must file the visa application with Japan Immigration on your behalf. You should receive copies of the forms they submit (Certificate of Eligibility, or COE). If a sending organization says they handle visa processing but cannot show you the COE when it is ready, ask clearly where it is and what it says.

Sending organization contract and fee breakdown: The licensed sending organization (XKLĐ) you work with must provide a written contract in Vietnamese that specifies every fee, what each fee covers, and under what conditions fees are refundable. Vietnamese government regulations cap the fees licensed organizations can charge. Any fee structure that cannot be explained item by item — or that uses vague categories — is a warning sign.

Dispatch or support organization registration: In Japan, the receiving organization and any support organization involved in your placement must be registered under the SSW framework. You can request their registration numbers and verify them against the official JLPT and Skills Testing Authority records.

Start now with what you can control: passport validity, national ID, birth certificate, household registration, education documents, and work history records. These have the longest lead times if renewal or replacement is needed.

Once you have a clear sector direction (food production, manufacturing, agriculture, or hospitality), register for the relevant skills test and begin JLPT preparation. These certifications cannot be rushed — they require consistent study over months, not weeks.

Only after you have passed (or are close to passing) the required tests does it make sense to engage seriously with a sending organization. Entering that process without your certifications ready puts you in a weaker negotiating position and increases the pressure to act quickly.

Document gathering is not glamorous preparation. But workers who arrive at the employer or visa stage with complete, ordered documents move through the process faster and with fewer problems than workers who scramble to fill gaps under time pressure.

Any operator who asks to hold your original passport or ID card for any period of time is operating against legal norms. Document confiscation is one of the most recognized early signs of labor exploitation in international migration contexts.

If you are asked to sign documents you have not read or do not understand — especially in a language you do not speak — do not sign. A legitimate process will give you time to read and ask questions.

If the fee breakdown cannot be provided in writing, do not proceed. In Vietnam, DOLAB-licensed sending organizations are required by law to provide itemized written contracts. The absence of one is grounds for disengagement.

If your labor contract is shown to you only a few days before departure, or only at the airport, that is not acceptable. You should have reviewed and confirmed your contract well in advance.
