International Internships in Japan — Visa Q&A Summary for HR Managers

Is a visa required for foreigners to do an internship in Japan?

Yes.

Foreign nationals must obtain, in advance, a status of residence (visa) appropriate to the purpose of their internship activities in Japan.

The applicable visa depends on the internship format. The three main categories are the Designated Activities visa, Cultural Activities visa, and Temporary Visitor (Short-Term Stay) visa.

1. Visa Type	Designated Activities	Temporary Visitor	Cultural Activities
2. Length of Stay	Over 90 days, up to 1 year	Up to 90 days	Over 90 days
3. Remuneration	Paid	Unpaid	Unpaid

Eligibility is determined primarily by:
1) Whether academic credit is granted by the university
2) Whether remuneration is paid
3) Length of stay

Do visa requirements differ between paid and unpaid internships?

Yes, the review criteria differ significantly.

Unpaid Internships

If the educational purpose is clear and the objective is to learn through practical experience in Japan, visa approval is generally more straightforward. In such cases, the Cultural Activities or Temporary Visitor visa is typically used. The student must demonstrate the ability to cover living expenses (e.g., bank balance certificates).

Paid Internships

Receiving wages or stipends is regarded as “work” under Japanese law. Applications will be reviewed on points such as:

• Compliance with minimum wage
• Appropriateness of the employment contract and terms
• Working hours and social insurance compliance
• Relevance to the student’s field of study (not merely labor substitution)

Where labor law violations (e.g., unpaid wages, excessive hours) are suspected, scrutiny becomes stricter.

What are the requirements for the Designated Activities (Internship) visa?

The Designated Activities (Internship) visa is examined on a case-by-case basis under ministerial notification. Typical conditions include:

• The applicant is enrolled at a foreign university or graduate school (limited application for students at Japanese universities)
• Internship content is closely related to the student’s academic field
• The host company can provide an educationally appropriate environment
• The student intends to depart Japan after the internship (i.e., not for immediate employment)
• Sufficient funds for living expenses during the stay can be demonstrated

For paid internships, special attention is given to the reasonableness of wages and the alignment between duties and the student’s major.

Requirements for the Designated Activities (Internship) Visa

When inviting overseas students for internships, the applicable status of residence varies by remuneration and duration. This page explains the most commonly used Designated Activities visa requirements.

Are post-graduation internships possible?

As a rule, the Designated Activities (Internship) visa is intended for students who are currently enrolled.

For graduates, alternative statuses such as “Designated Activities (Job-Hunting)” or work-eligible categories like “Engineer/Specialist in Humanities/International Services” should be considered.

For foreign students enrolled at Japanese universities who receive job offers via internships, a status change from “Student” to a work-eligible category (e.g., Engineer/Specialist in Humanities/International Services) at the time of graduation allows lawful employment.

Are there limits on internship duration?

Under the Designated Activities visa, the general upper limit is 1 year.

In many cases, applications are submitted for 3–6 months. If using a Temporary Visitor visa, the stay is capped at 90 days (extensions are not permitted).

The balance between internship content and duration is reviewed; for longer stays, a detailed training plan is recommended.

What responsibilities do host companies have?

Key responsibilities include:

• Clarify educational purpose: ensure activities contribute to learning, not simple labor substitution
• Documentation: internship plan, acceptance letters, and related materials
• Living support: housing arrangements, practical guidance, Japanese language support, etc.
• Labor management (for paid internships): wages, working hours, and social insurance compliance
• Safety & compliance: accident prevention, emergency procedures, and anti-harassment measures

Authorities expect a substantive educational/training environment rather than a purely nominal acceptance.

Is it possible to obtain employment in Japan after an internship?

Yes. For students coming from overseas universities, the common pathway is to return home, graduate, and then be invited to Japan under a work-eligible status such as “Engineer/Specialist in Humanities/International Services.”

For international students at Japanese universities, if a job offer is secured through an internship, they can change from “Student” to a work-eligible status upon graduation and commence employment.

What documents are required for the Designated Activities (Internship) visa application?

Typical documentation includes:

• Certificate of Enrollment (English/Japanese)
• Academic transcript (optional)
• Internship plan (content, schedule, supervisor details)
• Corporate documents of the host company (certificate of registry, company profile, list of officers, etc.)
• Proof of funds for living expenses (bank balance certificate, sponsor income proof, etc.)
• Passport and ID photo
• Application for Certificate of Eligibility (where applicable)

These are general items only. Each case requires consistent and accurate documentation; expert support is recommended.

What are common reasons for denial of the Designated Activities (Internship) visa?

Even with proper applications for the Designated Activities or Cultural Activities visa, approvals may be denied. Reviews are strict; minor errors or inconsistencies can trigger concerns. Below are common causes of denial and how to avoid them.

1) Internship content unrelated to the student’s major

This is the most frequent reason for denial. The internship must be part of the student’s education. If activities are unrelated to the major, educational value is not recognized.

Examples:
• Economics major → kitchen assistant at a restaurant → ✕ high risk of denial
• Architecture major → assistant for on-site safety management → ○ more likely to be approved

Countermeasure: Clearly explain the link between the internship and the major in the plan. Describe how tasks support academic learning.

2) Incomplete or inconsistent documents

Multiple documents are required; inconsistencies or omissions raise red flags.

Common issues:
• Dates on the Certificate of Enrollment do not match the academic year on the application
• Internship period does not coincide with university breaks where required
• Mismatch between host company’s business and internship duties
• Insufficient financial evidence (e.g., bank balance certificates)

Countermeasure: Carefully reconcile all details and share information between the company and applicant in advance.

3) Insufficient hosting framework

Denials may result if the host lacks:

• A designated supervisor
• Structured tasks suitable for interns
• Proper corporate registration (shell companies are disfavored)
• A clean compliance history (no record of encouraging illegal employment)

Plans that appear merely formal or that resemble part-time employment rather than training are particularly problematic.

Countermeasure: Demonstrate a genuine educational intent and framework. Supplement with company brochures, registry certificates, staff lists, etc.

4) Inappropriate labor conditions for paid internships

Paid internships must comply with labor laws. Risk factors include:

• Hourly wage below the regional minimum
• Failure to enroll in social insurance when required
• Working/Rest hours not compliant with labor standards
• Tasks consisting mainly of simple labor without educational value

Countermeasure: Ensure full compliance with labor law. The program must remain education-first, not de facto employment.

5) Suspicion of purposes other than study or training

Screening focuses on whether the stay truly serves the stated purpose. Concerns include:

• No clear plan after the internship (no intent to return)
• Weak financial footing (insufficient proof of funds)
• Repeated short stays by multiple foreigners at the same company

➡ Countermeasures:
• State the plan to depart Japan after the internship
• Document how the program fits academic or career plans
• Provide robust financial evidence (self/family support, etc.)

6) Other denial cases

Case 1: Applicant had already graduated (enrollment is required)
Case 2: Internship too short (e.g., ~1 week) and deemed lacking educational value
Case 3: Interns immediately assigned to routine frontline work (no training element)
Case 4: False statements in documents (e.g., academic fraud)
Case 5: Late submissions or missing documents, etc.
