Engineer Visa Degree & Major Matching Rules Explained

The work visa that most foreign professionals in Japan hold has a long official name: "Engineer / Specialist in Humanities / International Services", usually shortened to 技人国 (gijinkoku). It covers office and technical professionals — software engineers, mechanical and civil engineers, accountants, marketers, planners, translators, interpreters, and language teachers in companies. The single rule that decides most applications is the same one that confuses the most people: your academic background (or work experience) must be relevant to the job you will do.

This guide explains exactly how that degree-and-major matching rule works: what "related field" really means, how the Engineer track and the Humanities/International Services track are judged differently, the alternative routes when your degree does not match (the 10-year and 3-year experience rules, and the IT certification rule), the documents you need, processing time, fees, the points immigration screens for, and the most common reasons applications are refused.

What the Engineer / Humanities / International Services Visa Covers

This status of residence is the main route for white-collar and technical employment in Japan. It is a single status that bundles three categories of work:

• Engineer — work requiring knowledge in the fields of physical sciences, engineering, or other natural sciences: software development, systems engineering, network/infrastructure, mechanical, electrical, civil and chemical engineering, and similar technical roles.
• Specialist in Humanities — work requiring knowledge in the humanities or social sciences: accounting, finance, legal affairs, sales and marketing planning, human resources, general corporate planning, consulting, and similar.
• International Services — work requiring thinking or sensitivities based on a foreign culture: translation, interpretation, language instruction, public relations, overseas business liaison, international trade, and design that draws on foreign cultural sensibility.

What this status does not cover is so-called "simple labor" — routine manual or service work that does not require specialized knowledge. Factory line work, basic food-service, cleaning, and general construction labor fall outside 技人国 (those are addressed by other statuses such as Specified Skilled Worker). The whole screening logic flows from this distinction: the job must genuinely require the specialized knowledge your education gave you.

The Core Rule: Relevance, Not an Exact Match

The requirement that catches the most applicants is the relationship between your background and your duties. A common misunderstanding is that your major must have the same name as your job. That is not the test. The legal test is whether the knowledge and skills you acquired (through your degree or your experience) are relevant to the duties you will perform.

• The match is judged on substance, not job title. Immigration reads the actual course of study and the actual job description.
• The relationship must be explainable — you should be able to draw a clear line from what you learned to what you will do.
• The Engineer track is judged broadly; the International Services track is judged somewhat more strictly (see the next section).
• A perfect, word-for-word match is never required. A reasonable, demonstrable connection is.

The Three Tracks and How Each Is Judged

An important nuance for International Services: for the typical duties of translation, interpretation, language instruction, public relations, advertising, and overseas business liaison, the law sets a 3-year experience requirement — but a person who graduated from a relevant major is exempt from that 3-year requirement. So a fresh university graduate with a relevant major can take an International Services job without the 3 years.

The Academic (Degree) Requirement

The standard academic requirement is one of the following:

• A bachelor's degree or higher (including a master's or doctorate) from a university in Japan or abroad, in a field relevant to the work; or
• An equivalent or higher education; or
• For graduates of a Japanese vocational school: a "Diploma" or "Advanced Diploma" in a relevant field; or
• The work-experience route (10 years, or 3 years for certain International Services duties) where no relevant degree exists; or
• For IT work, a designated information-technology certification in place of a degree.

What Counts as a "Related Field"

Because relevance is judged on substance, the practical question is always: can you connect your transcript to your job description? Some guidance:

• Engineer track: majors in computer/information science, electrical/electronic engineering, mechanical engineering, civil/architectural engineering, chemistry, physics, mathematics and similar natural sciences are read broadly. An information-science graduate, in particular, can move across most IT roles.
• Humanities track: economics, business administration, commerce, law, sociology, international relations, and similar social-science majors map to accounting, finance, sales planning, HR, marketing, and corporate planning.
• International Services track: foreign languages, linguistics, literature, international/area studies, and design map to translation, interpretation, language teaching, PR, and culturally-informed design.
• Borderline cases (e.g., a science graduate taking a marketing job, or an arts graduate taking an engineering job) need a careful written explanation showing which specific courses relate to the duties — and may still be refused if the link is weak.

Immigration will look at your actual transcript, not just the degree name. If your major name is ambiguous, listing the relevant courses you completed strengthens the application considerably.

The Work-Experience Alternative (10 Years / 3 Years)

If you do not have a relevant degree, you may still qualify through practical experience:

• 10 years of relevant work experience for Engineer and Humanities duties (the time you spent studying the subject at university, technical college, or high school can be counted toward these 10 years).
• 3 years of relevant work experience for International Services duties such as translation, interpretation, language instruction, public relations, advertising, overseas business liaison, design, and product development. (As noted above, a university graduate — in any major — is exempt from this 3-year requirement for translation, interpretation, and language instruction only.)

The experience must be documented — usually with an employment certificate from your previous employer(s) stating your position, duties, and the exact period of employment. Vague or unverifiable experience is a frequent cause of trouble, so gather solid evidence before applying.

The IT Certification Exception

For information-technology work, Japan provides a special route that bypasses both the degree and the 10-year experience: if you hold an IT certification designated by the Ministry of Justice, you can qualify for IT engineering work on that basis alone.

• Designated qualifications include certain Japanese IPA examinations and a list of designated foreign IT qualifications from partner countries.
• This route is widely used by IT professionals who studied an unrelated subject but hold a recognized IT certification.
• It applies to IT/engineering duties; it does not extend to non-IT Humanities or International Services jobs.

Japanese Vocational School (Senmon Gakko) Graduates

Graduates of a Japanese 専門学校 who hold a 専門士 (Diploma) or 高度専門士 (Advanced Diploma) can satisfy the academic requirement — but with an important difference:

• For vocational-school graduates, the major-to-job relevance is examined more strictly than for university graduates. The connection between the specific course you completed and your actual duties must be clear and direct.
• A university graduate's degree is read broadly; a 専門士 holder's course content is read closely. For example, a graphic-design 専門士 taking a web-design job is fine, but the same person taking a general sales job may be questioned.
• This is one of the most common stumbling points: many 専門学校 graduates assume a diploma alone is enough, when in fact the course-to-duties match is decisive.

Required Documents

The exact list depends on the size and category of your employer (Immigration sorts companies into Categories 1–4, with large/listed companies needing fewer documents). A typical change-of-status or COE application includes:

• Application form for Certificate of Eligibility or for change/extension of status of residence.
• Photograph (4cm × 3cm) and passport / residence card.
• Your academic proof: degree certificate and, very importantly, an academic transcript showing the courses you took — or the 専門士/高度専門士 certificate, or your IT certification, or employment certificates for the experience route.
• Employment contract or letter of offer stating your duties, working hours, and salary.
• A written explanation of duties — a clear description of what you will actually do, which is central to showing the role is specialized and matches your background.
• Company documents: company registration, the most recent financial statements, a company overview/brochure, and a withholding-tax statement where required.
• Additional documents for Category 3 or 4 employers from April 15, 2026: a declaration concerning the representative of the accepting organization, and, where the applicant will mainly perform interpersonal duties using language ability, evidence of CEFR B2-level language proficiency may be required.
• Additional documents for Category 3 or 4 employers from April 15, 2026: a declaration concerning the representative of the accepting organization, and, where the applicant will mainly perform interpersonal duties using language ability, evidence of CEFR B2-level language proficiency may be required.
• Additional documents for Category 3 or 4 employers from April 15, 2026: a declaration concerning the representative of the accepting organization, and, where the applicant will mainly perform interpersonal duties using language ability, evidence of CEFR B2-level language proficiency may be required.
• For change of status from Student: graduation certificate (or expected-graduation certificate) and, if applicable, a record of your part-time work hours.

The Application Process Step by Step

Processing Time and Fees

The following fees and timeframes apply for applications accepted on or after April 1, 2025. For official details, see the Immigration Services Agency of Japan.

If you engage an administrative scrivener (gyoseishoshi) to prepare and file the case, their professional fee is separate and varies with the complexity of the case. The government fees above are the only mandatory charges.

What Immigration Screens For

Behind every decision, the examiner is checking a consistent set of points:

• Specialization of the duties — does the job genuinely require specialized knowledge, or is it really simple labor dressed up with a fancy title?
• Degree/experience relevance — is there a demonstrable link between your background and your duties?
• Salary appropriateness — are you paid at least the same as a Japanese national doing equivalent work? An unusually low salary suggests the role is not truly specialized.
• Company stability and continuity — can the employer realistically provide the specialized work on an ongoing basis (size, finances, business content)?
• Genuineness and necessity of the role — does the company actually need this position?
• Your compliance history — tax payment, and (for students) staying within the 28-hour part-time limit.

Common Reasons for Refusal

• The duties are not specialized. The job looks like simple labor or routine non-technical work that any person could do without the degree. This is the single most common refusal reason.
• No relationship between major and duties. The transcript and the job description cannot be connected — common for 専門学校 graduates and for borderline university majors.
• Salary too low. Below the level paid to comparable Japanese employees, or below what makes the "specialized" claim credible.
• Weak or unstable employer. The company's scale, finances, or business content cast doubt on whether a genuine specialized role exists.
• Insufficient or inconsistent documents. Missing transcript, vague duties description, or experience that the previous employer will not certify.
• Past violations. Most often, a student applicant who exceeded the 28-hour weekly part-time limit, or unpaid taxes / residence-tax arrears.

Changing Jobs and the Certificate of Authorized Employment

The Engineer/Humanities/International Services status lets you change employers without immediately re-applying, as long as the new job stays within the activities the status permits — so degree/experience relevance still matters at every job change. Key points:

• Notify Immigration within 14 days of leaving an employer and within 14 days of joining a new one (notification of change of contracting organization).
• Consider obtaining a Certificate of Authorized Employment before or soon after switching. This optional certificate confirms in advance that your new duties are appropriate for your status, reducing uncertainty at your next extension.
• If the new duties differ in kind from your background (e.g., moving from engineering to pure sales), reassess the relevance carefully — the new role must still be supported by your degree or experience.
• Your period of stay is unchanged by a job change; you simply continue until your current expiry, then extend in the normal way.

Frequently Asked Questions

Summary

The Engineer/Humanities/International Services visa is generous in its scope but unforgiving on one point: the work must be genuinely specialized and connected to your background. If your degree or experience lines up with a real, specialized role at a stable employer paying an appropriate salary, approval is the normal outcome. The mistakes that cause refusals are almost always the same — an over-general job, a missing transcript, a forced major match, or a salary that undercuts the "specialized" claim. Get those right, and the rest of the process is routine.
