Engineer/Specialist in Humanities/International Services Visa Complete Guide

The Engineer/Specialist in Humanities/International Services visa — in Japanese, 技術・人文知識・国際業務 (gijutsu·jinbun chishiki·kokusai gyomu), often shortened to 技人国 (gijinkoku) — is by far the most common work visa for foreign professionals in Japan. It covers most white-collar jobs: software engineers, IT staff, mechanical and electrical engineers, accountants, marketers, corporate planners, sales coordinators, interpreters, translators, designers, and overseas-business specialists.

This guide explains everything a foreign worker needs to understand before applying or changing to this status: who qualifies, the all-important relevance test between your degree and your job, the documents Immigration wants to see, how long it takes, what it costs, the points examiners focus on, the most common reasons applications are refused, and how this status compares to related ones such as the Business Manager visa and naturalization. The aim is to give you an accurate, practical picture so you can prepare a strong application.

What the 技人国 Visa Covers — and What It Doesn't

The 技人国 status of residence authorizes work that requires specialized knowledge or skills in the natural sciences, the humanities, or in fields requiring foreign-culture-based sensitivity. The key idea is that the work is genuinely professional and cannot be performed by just anyone — it draws on academic knowledge or specialized experience.

Typical qualifying jobs include:

• Engineer track: software development, systems engineering, network and infrastructure work, mechanical/electrical/civil engineering, manufacturing technology, R&D.
• Specialist in Humanities track: accounting, finance, corporate planning, marketing, sales planning, human resources, legal affairs, consulting.
• International Services track: interpretation, translation, language teaching at private companies, overseas trade and business liaison, international PR, fashion or interior design that requires a foreign sensibility.

What the visa does not cover is unskilled or simple labor. Factory line work, restaurant service, retail cashier work, cleaning, construction labor, and similar jobs do not qualify under 技人国 — even if you hold a university degree. Those jobs fall under other statuses such as Specified Skilled Worker (SSW) or are not eligible at all.

The Three Categories Inside One Visa

Although it is a single status of residence, 技人国 bundles three historically separate categories. Knowing which one applies to you matters because the requirements differ slightly.

Many real jobs blend categories — for example, an IT engineer who also handles overseas client communication. Immigration assesses the main duties and the overall fit, so a clear written job description is essential.

Core Requirements at a Glance

To be granted 技人国 status, the following conditions generally all need to be satisfied:

• Qualifying background: a university degree (bachelor's or higher, from any country) or Japanese senmon gakko diploma related to the job, OR the relevant work experience (10 years for Engineer/Humanities, 3 years for International Services), OR a recognized IT qualification for engineering roles.
• Job content qualifies: the duties require specialized knowledge in natural sciences, humanities, or international services — not simple labor.
• Relevance: a logical connection between your academic field or experience and the job duties.
• Adequate, fair salary: pay equal to or above that of a comparable Japanese employee.
• A stable employer: the company is real, operating, and financially able to pay you.
• Clean record: no serious immigration violations or false statements.

The Degree-to-Job Relevance Test

This is the single most important and most misunderstood requirement. Immigration does not simply ask "do you have a degree?" It asks "does the knowledge from your degree connect to the work you will do?"

Clear examples of good relevance:

• Computer science graduate → software engineer (strong match).
• Economics or business graduate → marketing, sales planning, or corporate planning (match).
• Mechanical engineering graduate → manufacturing or design engineer (strong match).
• Foreign-language or literature graduate → translator or interpreter using that language (match).
• Native speaker of a foreign language → interpretation/translation in that language (match under International Services).

The Work-Experience Route (No Degree)

You do not always need a degree. Practical experience can substitute, but the bar is high and the documentation must be solid:

• Engineer and Specialist in Humanities: at least 10 years of relevant work experience (this can include time spent studying the relevant subject at university or vocational school in some cases).
• International Services: at least 3 years of relevant experience. However, university graduates (in any field) who engage in interpretation, translation, or language teaching are exempt from the experience requirement.
• IT/engineering qualifications: certain information-technology examinations designated by the Ministry of Justice can replace the degree requirement for engineering roles, even without 10 years of experience.

To prove experience, you will need employment certificates from former employers stating your job title, duties, and dates of employment. Vague or unverifiable experience is a common weak point, so gather official letters early.

Salary and the Equal-Pay Principle

There is no single fixed minimum salary written into the law, but a crucial rule applies: your salary must be equal to or higher than what a Japanese national would receive for the same work. This is the "equal pay for equal work" principle in immigration screening.

In practice, examiners look for:

• A stable monthly salary that supports independent living — commonly around 200,000 yen per month or more for full-time professional roles, though this varies by region and industry.
• Consistency with the company's own pay scale and with the regional market rate for the role.
• A genuine employment relationship (not a sham arrangement just to obtain a visa).

Required Documents

The exact list depends on the employer's category (large listed companies face lighter documentation than small startups), but a typical application includes:

From you (the applicant)

• Application form for the Certificate of Eligibility, change, or extension.
• Passport and residence card (for in-Japan applications).
• Photo (4cm × 3cm).
• Degree certificate / diploma and, when relevant, academic transcripts.
• For the experience route: employment certificates from former employers proving your years of relevant work.
• Relevant professional or IT qualification certificates, if any.
• Proof of language ability at CEFR B2 level or above (e.g., JLPT N2, BJT 400+) — required for applications filed on or after 15 April 2026 when the employer falls under Immigration's Category 3 or 4 and the job involves customer-facing duties using language skills, such as interpretation, translation, sales, or customer support.

From the employer

• Employment contract or letter of offer stating job duties, salary, and working conditions.
• Company registration certificate and a company overview/brochure.
• Financial statements or a statement of profit and loss (to show ability to pay).
• Statutory record of total tax withholding or equivalent, depending on company category.
• For Category 3/4 employers, applications filed on or after 15 April 2026 also require a declaration form concerning the organization's representative.
• A written explanation of duties describing exactly what you will do and how it connects to your background — often the deciding document.

The Application Process Step by Step

Processing Time and Government Fees

The period of stay granted is usually 1, 3, or 5 years, and in some cases 3 months, depending on the stability of the employer and your record. The government fee is paid by revenue stamp only when the application is approved. If you hire an administrative scrivener (gyosei shoshi) to prepare the application, professional fees are separate and vary by case.

What Immigration Examiners Focus On

Examiners are essentially answering four questions:

• Is the work genuinely specialized? The duties must require knowledge that an ordinary worker would not have.
• Does your background fit the work? Degree field or documented experience must connect to the duties.
• Can the employer support you? The company must be real, operating, and financially capable of paying the stated salary.
• Are you a reliable applicant? A clean immigration history, accurate statements, and proper tax/pension compliance (for renewals) all matter.

Common Reasons for Refusal

Most refusals fall into a handful of recurring patterns:

• The job is unskilled. Simple factory, service, retail, or manual work does not qualify, regardless of your degree.
• No clear relevance between your major/experience and the duties (especially scrutinized for senmon gakko graduates).
• The employer looks financially unstable or cannot demonstrate it can pay the salary — a frequent issue with very new or very small companies.
• The salary is too low or below the equal-pay standard for the role and region.
• Incomplete or inconsistent documents, including mismatches between the contract, the explanation of duties, and the actual role.
• Past immigration problems — overstays, undeclared part-time work beyond permitted hours, unpaid taxes/pension, or false statements in earlier applications.

技人国 vs. Business Manager Visa

Foreign workers often confuse these two, but they serve opposite situations.

In short: if a company hires you to do engineering, humanities, or international-services work, you need 技人国. If you are founding or managing your own company in Japan, you need the Business Manager visa, which, under the rules in force since 16 October 2025, requires an independent physical office, capital/investment of at least 30 million yen, the employment of at least one full-time staff member, a business plan confirmed by a qualified expert, and Japanese ability (CEFR B2 / JLPT N2 or above, held by the applicant or a full-time employee).

Toward Permanent Residence and Naturalization

Time spent on 技人国 counts toward longer-term goals.

Permanent residence: generally requires continuous residence in Japan for around 10 years (with at least 5 of those years on a work status), a stable income, proper tax and pension payment, and good conduct. Holders of Highly Skilled Professional status can qualify faster (in as little as 1–3 years under the points system).

Naturalization: becoming a Japanese citizen is a separate process handled by the Legal Affairs Bureau (not Immigration). General requirements include roughly 5 years of continuous residence, being 18 or older with legal capacity, good conduct, a stable livelihood, and renouncing your previous nationality (Japan does not generally allow dual nationality). The naturalization document set is extensive — it typically includes your family register or birth/marriage certificates from your home country, proof of residence, tax payment certificates, income statements, employment certificates, and a written motivation statement — and the screening is more demanding than for permanent residence.

Renewal, Job Change, and Notifications

Once you hold 技人国, a few ongoing obligations matter:

• Renewal (extension): apply before your period of stay expires. Renewal screening checks that you continued the qualifying work and met tax/pension obligations.
• Changing jobs: you can change employers within the same status as long as the new job still qualifies under 技人国. You must notify Immigration of the change of contracting organization within 14 days.
• Different field of work: if your new job no longer fits your status (e.g., moving into management or a non-qualifying role), you may need a change of status, not just a notification.
• Employment Qualification Certificate: when changing jobs, you can voluntarily apply for this certificate to confirm in advance that the new role qualifies — a smart way to avoid surprises at renewal.
• Side work: work outside your authorized activity requires separate permission; unauthorized work can jeopardize your status.

Frequently Asked Questions

Summary

The 技人国 visa opens the door to a real professional career in Japan, and it is far more attainable than many applicants assume — provided the job is genuinely specialized, your background connects to it, and the paperwork tells a clear, consistent story. Focus on a strong explanation of duties, honest documentation of your degree or experience, and a financially sound employer, and your application stands on solid ground.
