1. Who Qualifies for the Engineer Visa

The official name is the Engineer/Specialist in Humanities/International Services visa (技術・人文知識・国際業務). It’s the primary work visa for white-collar foreign professionals in Japan — software engineers, IT professionals, data scientists, designers, and similar roles all fall under this category.

To qualify, you need to meet requirements across three areas: your employer, your qualifications, and the role itself.

Your employer must be a registered Japanese company

The company offering you the job must be a legally registered entity in Japan — a kabushiki kaisha (株式会社, KK) or godo kaisha (合同会社, GK) or equivalent. Startups registered in Japan qualify. Foreign companies with Japan branches qualify. Freelance or self-employment does not qualify for this visa category.

You need either a degree or significant experience

This is where most questions arise. The requirement is one of the following:

Important: The degree must be relevant to the job you’re being hired for. A computer science degree for a software engineering role: clearly fine. A business degree for a software engineering role: may require additional documentation explaining the connection. A history degree for a software engineering role: likely to be questioned — see Section 7 on when to use a professional.

The role must match your qualifications

Immigration officers check that the job you’re being hired for logically requires the qualifications you hold. A software engineer with a CS degree being hired to write software: straightforward. The connection must be clear in the documentation — if it isn’t obvious, your employer’s HR or an immigration lawyer will need to explain it in a supplementary letter.

Your salary must be fair

Your salary must be equivalent to or greater than what a Japanese national would earn in the same role. Immigration has tightened checks on this in recent years. Companies hiring through established channels (TokyoDev, Japan Dev, major tech companies) are well aware of this requirement and price offers accordingly. This is the employer’s problem to solve, not yours — but be aware that very low offers may flag issues.

2. Complete Document Checklist

The engineer visa application has two separate document sets: what you provide, and what your employer provides. Most people are surprised by how much the employer handles.

Documents you provide

• ✅ Valid passport — original, with at least 6 months validity remaining
• ✅ University degree certificate — official copy, with certified translation if not in English or Japanese
• ✅ University transcript — official copy showing coursework completed
• ✅ CV / resume — typically in English; some companies also request a Japanese version (rirekisho)
• ✅ Passport-sized photo — 4cm × 3cm, white background, taken within 3 months
• ✅ Completed application form — provided by your company or immigration lawyer
• ✅ Employment contract — signed copy of the offer letter / employment agreement

If you’re applying on the basis of work experience rather than a degree, you’ll also need:

• ✅ Employment certificates from each previous employer covering the 10-year period — on company letterhead, stating your role, dates, and responsibilities
• ✅ Explanation letter connecting your experience to the role you’re being hired for

Documents your employer provides

• ✅ Certificate of Eligibility (COE) application — the main application submitted to the Immigration Services Agency
• ✅ Company registration certificate (登記事項証明書) — proves the company is a registered Japanese entity
• ✅ Company financial statements — typically the most recent 2 years of financial accounts
• ✅ Explanation of the role — a letter describing what you’ll be doing and why your qualifications are relevant
• ✅ Reason for hiring letter — explains why the company is hiring a foreign national

Practical note: Your employer — or their immigration lawyer — will provide you with a checklist and tell you exactly what they need from you. Follow their list precisely. Don’t add documents they haven’t asked for, and don’t omit anything they have. Incomplete applications are one of the most common causes of delay.

3. The Application Process, Step by Step

Step 1: Accept the job offer and confirm visa sponsorship

Before anything else, confirm in writing that your employer will sponsor the engineer visa. Reputable companies hiring international engineers do this as standard — but confirm it explicitly during offer negotiation. Ask specifically: “Will the company handle the COE application?” and “Do you use an immigration lawyer for this process?” Both should be yes.

Step 2: Provide your documents to your employer

Your HR team or their immigration lawyer will send you a document request. Gather and send everything on their list. Key things that slow people down at this stage:

• Degree certificates that need to be retrieved from a university registry (allow 2–4 weeks if your university is slow)
• Certified translations of documents not in English or Japanese (allow 1–2 weeks and budget ¥5,000–15,000 per document)
• Employment certificates from previous employers that need to be requested formally

Start gathering these the moment you accept an offer — don’t wait for the formal document request.

Step 3: Employer submits the COE application to immigration

Your employer (or their immigration lawyer) submits the Certificate of Eligibility application to the Immigration Services Agency of Japan. This is done by your employer — you don’t do this part. The application is submitted in Japan, and you don’t need to be in Japan for it to be processed.

Step 4: Wait for the COE

Standard processing: 1–3 months. Large, established companies that frequently sponsor visas sometimes get faster processing because immigration is familiar with their applications. Startups applying for the first time may take longer.

You’ll receive updates from your employer when there’s news. Don’t contact immigration directly during this period — your employer or their lawyer is the point of contact.

Step 5: Receive the COE and apply for your visa

When the COE is approved, it’s sent to your employer in Japan, who then sends it to you overseas (usually by international post). Once you have the physical COE, go to the Japanese Embassy or consulate in your country and apply for your visa sticker. Bring:

• Your COE (original)
• Your passport
• Completed visa application form (download from the Embassy website)
• Passport photo
• Application fee (varies by country — check the Embassy website)

Processing at the Embassy: 5–10 working days in most countries.

Step 6: Enter Japan

At the airport, present your passport with the visa sticker and your COE. Immigration will issue your Residence Card (在留カード) on the spot. This is your ID in Japan — keep it with you at all times.

Step 7: Register your address within 14 days

Go to your local city hall (区役所 or 市役所) within 14 days of arrival and register your address. Bring your Residence Card and passport. They’ll update your Residence Card with your address — this is a legal requirement and unlocks access to health insurance, banking, and other services.

4. Timeline: How Long Everything Takes

Plan for 3 months as your baseline when negotiating your start date. Tell your employer you need approximately 3 months from offer acceptance to starting work. Most Japanese companies are familiar with this timeline and will accommodate it. If they’re pushing for faster, ask whether they’ve used an immigration lawyer — expedited COE processing is sometimes possible for companies with established relationships with immigration.

5. Switching from a Working Holiday Visa: How It Works

If you’re currently in Japan on a working holiday visa and have secured a job offer, you can change your visa status from within Japan. This is one of the most common paths — many engineers arrive on a WHV, find a full-time role while here, and then switch to an engineer visa without leaving the country.

The key differences from applying from overseas

• You apply at the local Regional Immigration Services Bureau — not the Japanese Embassy (you’re already in Japan)
• The process is called a “status of residence change” (在留資格変更許可申請, zairyū shikaku henkō kyoka shinsei)
• No COE is issued — instead, your Residence Card is updated directly with the new visa status
• You can continue working on your WHV while the application is pending — but only until your WHV expiry date; apply well before it expires

Critical timing: apply before your WHV expires

This is where WHV holders get into trouble. If your working holiday visa expires before your change-of-status application is processed, you’re in a difficult position. The rule of thumb:

• Apply at least 3 months before your WHV expires — processing takes 1–3 months
• If your WHV has less than 3 months remaining when you receive a job offer, contact your employer immediately and flag the timeline — they may be able to expedite
• If your WHV expires during processing and you’ve filed before expiry, you can generally remain in Japan on a “special permission to stay” while the application is pending — but confirm this with your employer’s immigration lawyer

Documents for a status change (additional to the standard list)

• Your current Residence Card
• Application form for status of residence change (available at immigration or from your employer)
• All the same documents as a standard engineer visa application

The document requirements are essentially the same as applying from overseas. Your employer handles the company-side documents; you handle your personal documents. The submission is made in person at the immigration bureau, usually by your employer’s HR or immigration lawyer on your behalf.

6. Common Mistakes That Cause Rejections and Delays

Most engineer visa applications are approved. But delays and rejections happen — and they almost always come from one of the following.

Mistake 1: Degree field doesn’t clearly match the role

This is the most common source of problems. Immigration expects a logical connection between your academic background and your job. If you studied business and you’re being hired as a software engineer, that connection needs to be explicitly explained in a supplementary letter — it won’t be assumed.

If your degree is clearly adjacent but not exact — mathematics for a data engineering role, for example — a well-written explanation from your employer is usually sufficient. If the connection is genuinely tenuous, get professional advice before submitting.

Mistake 2: Missing or incomplete employment certificates (experience route)

If you’re applying on the basis of 10 years’ experience rather than a degree, every year of that experience needs to be documented. A gap in the certificate chain — a company that no longer exists, a period of freelance work without formal documentation, a role you can’t get a certificate from — creates problems. Address these proactively before submitting, not after a rejection.

Mistake 3: Degree certificate without certified translation

If your degree certificate is in a language other than English or Japanese, it needs a certified translation. “Certified” means translated by a professional translator who attests to the accuracy — not Google Translate, not a bilingual friend. Immigration will reject or delay applications with non-certified translations.

Mistake 4: Timing issues on WHV switches

Applying for a status change too close to your WHV expiry is the most common crisis scenario for working holiday visa holders. Process your application as soon as you have a confirmed offer — don’t wait until you’ve signed the employment contract, because drafting the company documents takes time.

Mistake 5: Inconsistencies between documents

Your CV, your degree certificate, your employment certificates, and your employer’s description of your role all tell a story about you. Immigration reads all of them together. If your CV says you worked somewhere from 2018–2021 but your employment certificate says 2019–2021, that inconsistency will be noticed. Check every date, every role title, and every company name across all documents before submission.

Mistake 6: Using an employer not set up for visa sponsorship

Not every Japanese company has sponsored a visa before. A company with no experience in the process can make mistakes on their side of the application that cause delays or rejections — even when the candidate is perfectly qualified. Ask your employer directly: “Have you sponsored engineer visas before?” If the answer is no, recommend they use an immigration lawyer. This protects both of you.

7. When to Use a Professional — and When You Don’t Need To

Most straightforward engineer visa applications don’t require you personally to hire a lawyer — your employer’s HR or their immigration lawyer handles it. But there are specific situations where getting independent professional advice is worth the cost.

You probably don’t need independent professional help if:

• Your degree is in a clearly relevant field (CS, engineering, IT, mathematics)
• Your employer has sponsored visas before and has an established process
• Your employment history is clean and well-documented
• You have no prior visa complications in Japan or other countries

Get professional advice if:

• Your degree is in an unrelated field and you need to explain the connection
• You’re applying on the basis of 10 years’ experience without a degree
• There are gaps or complications in your employment history
• Your employer has never sponsored a visa and doesn’t have an immigration lawyer
• You’ve had visa complications in Japan or another country previously
• Your WHV is expiring soon and you’re concerned about timing
• You want to apply for Highly Skilled Professional status simultaneously
• You received a rejection or a request for additional information on a previous application

In these situations, the cost of a professional consultation is small compared to the cost of a rejected application — which means starting the entire process again, potentially missing your start date, and months of additional waiting.

8. Frequently Asked Questions

Can I work while my COE application is being processed?

If you’re outside Japan: no. You can’t work in Japan until you’ve entered on the visa. If you’re in Japan on a working holiday visa and have applied for a status change: yes, you can continue working on your WHV while the change application is pending — but only until your WHV’s expiry date.

How long is the engineer visa valid for?

The initial engineer visa is typically granted for 1, 3, or 5 years, depending on your employer’s track record and your qualifications. After your first visa period, renewal is usually straightforward if you’ve been employed and compliant throughout. Renewals are typically granted for longer periods over time.

What happens if I change jobs?

When you change employers, you must notify immigration within 14 days using the online immigration notification system. If your new job is in the same field (software engineering to software engineering), your visa status stays the same — you just update your employer information. You don’t need to apply for a new visa. If you’re moving to a significantly different type of work, check with your employer or an immigration lawyer whether a status change is required.

Can my family come with me?

Yes. Your spouse and dependent children can apply for a Dependent visa (家族滞在ビザ) once your engineer visa is approved. The process runs parallel — your family applies after your COE is issued. Your spouse on a Dependent visa can work up to 28 hours per week with a work permit (資格外活動許可).

Does the engineer visa lead to permanent residency?

Yes, via two routes. The standard route requires 10 years of continuous residence in Japan. The Highly Skilled Professional (HSP) route can reduce this to 1–3 years if you qualify based on the points system. See the HSP visa guide for details on whether you might qualify — it’s worth checking if your salary and qualifications are strong.

My application was rejected. What now?

First: don’t panic. A rejection is not a permanent bar. You’ll receive a reason for the rejection, which tells you exactly what to fix. In most cases, rejections on engineer visa applications come from document issues — missing information, unclear connections between qualifications and role, or employer-side documentation problems. Fix the specific issue identified, and reapply. At this point, engaging a professional to review your application before resubmission is strongly recommended.

I don’t have a degree. I have 8 years of experience. Do I qualify?

The requirement is 10 years. 8 years does not meet the threshold under the standard rules. Options: wait until you have 10 years, find an employer willing to sponsor you under a different visa category, or explore whether any of your academic history can be counted toward the 10-year requirement (some vocational school time counts in certain circumstances). This is a situation where a professional consultation is essential — the rules have nuances that vary by circumstance.

Your Next Steps

If your situation is straightforward — relevant degree, job offer from an experienced employer, clean history — here’s what to do right now:

1. Start gathering your documents today — degree certificate, transcript, employment certificates. Don’t wait for the formal request from your employer.
2. Confirm your employer has visa sponsorship experience — ask HR directly. If they don’t, recommend they use an immigration lawyer.
3. Negotiate your start date with 3 months buffer — this is the realistic COE processing timeline.
4. If your situation has any complexity — get a consultation with WeXpats before submitting. It’s far cheaper than fixing a rejection.

The engineer visa process is manageable. The mistakes that cause problems are predictable — and avoidable with the right preparation.
