Change Visa from Researcher to Engineer in Japan: Steps (2026)
If you hold Researcher, Professor or Cultural Activities status and you move into an engineering job at a company, you usually need a change of status to Engineer/Specialist in Humanities/International Services before you start the new job. The Immigration Services Agency (ISA) standard processing time is 1 to 2 months, but in practice you should plan for 1 to 3 months.
Many postdocs and researchers at Japanese universities and public research institutes want to move into industry. The visa step is often the part that worries them most. This guide explains when a change is needed, how long it takes, which documents ISA asks for, and how to plan your resignation date safely.
All rules are described as of October 2026, based on ISA sources. This is general information, not legal advice. ISA decides each case.
Key takeaways
Cultural Activities status does not allow paid work. You must change status before you start any job.
Professor status covers university research and teaching. Moving to a company requires a change of status.
Researcher status can cover research at private companies. If the new job is engineering rather than research, you need a change.
Do not start the new job before permission. Keep your current position until the decision, if you can.
Plan for 1 to 3 months. Applications increase before April each year.
Do you need to change your visa? Check your current status
Your current status of residence decides what you must do. Look at your residence card, not your contract or your institute's job title.
Your current status | What it covers (ISA) | Moving to an engineering job at a company |
|---|---|---|
Researcher (研究) | Research under a contract with a public or private organisation in Japan, including researchers at private companies | Change needed if the new job is engineering, development or production, not research |
Professor (教授) | Research, research guidance and teaching at universities and similar institutions | Change needed |
Cultural Activities (文化活動) | Academic or artistic activities without income, or specialised study of Japanese culture | Change needed. You cannot work at all until it is approved |
Highly Skilled Professional (i)(a) or (i)(b) | Work for a specific designated organisation | Change of status needed before changing employer |
Designated Activities (特定活動) | Depends on the designation in your passport | Check with ISA or a licensed specialist |
Why Cultural Activities is a special case
Some researchers at public research institutes stay under Cultural Activities, for example when they are invited and funded by a fellowship. ISA's definition says this status is for activities "without income" (収入を伴わない). So you cannot take a paid job, even part-time, until your change of status is approved.
Researchers who stay in research
If your new company role is truly research, you may be able to keep Researcher status. You still must notify ISA within 14 days about the change of contracting organisation. But most industry roles, such as process engineer, device engineer or measurement engineer, are engineering work, not research. These usually need the Engineer/Specialist in Humanities/International Services status.
Highly Skilled Professional holders: a different rule
If you hold Highly Skilled Professional (i), your status is tied to a designated employer. ISA states that you need a change of status permission when you change jobs. You must get this before you start with the new employer. At the Tokyo bureau, this can take about 1.5 months or more. You need at least 70 points under the new job's conditions. For details, read Highly Skilled Professional visa and job change.
The step-by-step timeline
A typical move from research into industry looks like this. Times vary by person and by season.
Step | What happens | Typical time |
|---|---|---|
1. Job search and interviews | You apply, interview and receive an offer | 2 weeks to 2 months |
2. Employment contract | You sign the contract, or a written offer with the start date "after visa permission" | 1 to 2 weeks |
3. Prepare documents | Your employer and a licensed specialist prepare the application with you | 1 to 3 weeks |
4. Apply to ISA | You apply at your regional immigration bureau or online | — |
5. ISA review | ISA reviews the application and may ask for more documents | 1 to 2 months standard; about 73 days on average for July 2026 approvals |
6. Permission | You pay the fee and receive a new residence card | 1 day |
7. Start work | You start the new job and notify ISA within 14 days of the new contract | — |
So from offer to first day, many people should expect 2 to 4 months. If your research contract ends soon, start early.
When to tell your institute
Do not resign too early. If your status is Researcher or Professor, staying in Japan for 3 months or more without doing your status's activity can be a reason to revoke your status, unless you have a justifiable reason. A common safe plan:
Get a written offer first.
Apply for the change of status while you are still in your current position, if possible.
Agree with your institute on an end date that fits the expected decision date.
Start the new job only after permission.
Your institute's rules on notice periods also matter. Check your research contract.
Which documents does ISA ask for?
ISA's document list depends on your employer's category (1 to 4). Category 1 and 2 employers need fewer documents. Category 3 and 4 employers need more. If you will be a dispatch worker, your employer is the dispatch agency, so its category counts.
Documents for all categories
Application form for change of status of residence
One photo (4 cm × 3 cm, taken within 6 months)
Passport and residence card (shown at the counter)
A document proving the employer's category
For dispatch work: pledges from the agency and the client, your employment terms, and the individual dispatch contract
Extra documents for Category 3 and 4 employers
Document | Who usually prepares it |
|---|---|
Written working conditions (employment terms) | Employer |
CV showing where and how long you did related work | You |
Degree certificate or proof of equal education | You |
Certificates of employment for related work, if you use experience | You and past employers |
Company registration certificate | Employer |
Description of the business | Employer |
Latest financial statements (Category 4 also needs more tax documents) | Employer |
Declaration about the representative (for applications from April 15, 2026) | Employer |
ISA can ask for more documents during the review. If you are leaving research before your contract ends, you may also be asked to explain your research period, the reason it ended, and how you found the new job. Keep a certificate of employment from your institute.
What about the April 2026 language rule?
From April 15, 2026, ISA asks for CEFR B2-level proof only when the job mainly uses language with people, such as translation or interpretation. Engineering work is not that type of job. You do not need JLPT N2 just because you are an engineer. See our Engineer/Specialist in Humanities visa guide.
Fees and the special period
The fee is paid when permission is granted. From October 1, 2026, it depends on the period of stay granted: from ¥10,000 for 3 months or less, up to ¥75,000 at the counter for 5 years or more. A 1-year permit is ¥33,000 at the counter (¥27,000 online). A 3-year permit is ¥64,000 (¥56,000 online). Applications received by September 30, 2026 paid the old fee of ¥6,000.
If you applied before your period of stay ends and the decision comes later, you can stay under your current status until the decision, or until 2 months after the expiry date, whichever comes first. ISA explains this on its special period page. This rule lets you stay in Japan, but it does not let you start the new job early.
Who can submit the application?
You can apply yourself at the regional immigration bureau for your address, or online. ISA's change of status page explains who can apply. A registered staff member of your employer, or a licensed lawyer or administrative scrivener (gyoseishoshi) who has notified ISA, can also submit it for you. You must be in Japan when the application is made. Using a specialist reduces errors, especially for Category 3 or 4 employers and dispatch work.
Making your research experience count
The visa is only one part. Companies also look at whether your research matches their work. Clean-room experience in a lab is valuable, but many fabs ask for experience on mass-production tools. Explain your work in industry terms: tools you operated, processes you controlled, data you analysed, and problems you solved. For more advice, read postdoc to industry in Japan and from cleanroom research to a fab job.

Frequently asked questions
Q. Can I work in a company with a Cultural Activities visa in Japan?
No. ISA defines Cultural Activities as activities without income. You cannot take a paid job, even part-time, while you hold this status. To join a company as an engineer, you must apply for a change of status, usually to Engineer/Specialist in Humanities/International Services, and wait for permission. The standard processing time is 1 to 2 months. Plan for 1 to 3 months, and keep your current activity until the decision.
Q. How long does it take to change from Researcher to Engineer visa in Japan?
ISA's standard processing period for a change of status is 1 to 2 months. In ISA's statistics for approvals in July 2026, a change to Engineer/Specialist in Humanities/International Services took about 73 days on average. Times are often longer before April. Add time for the job search and document preparation. Many people should expect 2 to 4 months from offer to first day.
Q. Can I keep my Researcher visa if I join a private company?
Sometimes. ISA's description of Researcher status includes researchers at private companies. If your new job is truly research under a contract with the company, you may keep the status and notify ISA within 14 days. If the job is engineering, development, process or production work, you usually need to change to Engineer/Specialist in Humanities/International Services. A licensed specialist can review your job description.
Q. Can I start my new job while my change of status application is pending?
No. You should not start the new job until ISA grants permission. While the application is pending, you can stay in Japan under your current status, within the special period rules (until the decision, or 2 months after your expiry date, whichever comes first). If you hold Cultural Activities status, you cannot do any paid work during this time. Agree a start date with your new employer that allows for the review.
Q. Which documents do I need to change from Professor to Engineer visa?
For all employers: the application form, a photo, your passport and residence card, and proof of the employer's category. For Category 3 and 4 employers, ISA also asks for your employment terms, a CV, degree certificate, company registration, business description and financial statements. From April 2026, these employers also submit a declaration about the representative. Dispatch work needs pledges and the dispatch contract. ISA may ask for more.
Q. Should I resign from my research position before applying?
Usually not. If possible, apply while you are still in your current position. Staying in Japan for 3 months or more without doing your status's activity can be a reason for revocation, unless you have a justifiable reason. A safe plan is: get a written offer, apply, agree an end date with your institute, and start work only after permission. Check your research contract's notice period too.
Q. Do I need JLPT N2 to change to an Engineer visa?
No, not for engineering work. The April 2026 rule asks for CEFR B2-level proof only for jobs that mainly use language with people, such as translation or interpretation. However, Japanese ability can still help in interviews and career growth. Some jobs list a Japanese level on the job card. Check each job's language requirement before you apply, and mention any Japanese study on your CV.
Summary
Cultural Activities, Professor and most Researcher holders need a change of status for engineering jobs.
Highly Skilled Professional (i) holders need a change of status before changing employer.
Plan for 1 to 3 months of ISA review, and 2 to 4 months from offer to first day.
Documents depend on the employer's category. Dispatch work needs extra pledges and contracts.
Do not resign too early, and do not start work before permission.
