Why the Engineer Visa Is Harder for Vocational School Graduates | Proving the Link Between Coursework and Job Duties

“I graduated from a vocational school and hold the Diploma of Specialist, yet my Engineer visa application was refused.” We hear this often. The education requirement itself is met, but the outcome turns on a single point: the relevance between the subjects studied and the job duties. This article confirms from the published guideline why this is a difficult category, and sets out how relevance is actually proved. For the basics of the education requirement, please see How to Obtain an Engineer Visa as a Vocational School Graduate.

The basis for “difficult” is in the text of the guideline

“Vocational school graduates get a stricter review” is not folklore among practitioners. The guideline published by the Immigration Services Agency of Japan explicitly distinguishes how relevance is judged, based on the nature of the educational institution.

On universities: “In light of the character of a university as such an educational institution, the relevance between subjects majored in at university and the work to be engaged in has traditionally been judged flexibly (a comparable judgment is applied to overseas universities).”

On specialized training colleges: “On the other hand, since a specialized training college is intended to develop the abilities necessary for an occupation or practical life, or to improve general education (Article 124 of the School Education Act), in principle a considerable degree of relevance is required between the subjects majored in at a specialized training college and the work to be engaged in.”

“Judged flexibly” versus “a considerable degree of relevance is required.” The difference in status under the School Education Act — a university as an institution that “imparts broad knowledge,” a specialized training college as one that “develops the abilities necessary for an occupation or practical life” — is carried directly into how applications are examined.

Educational institution	How relevance between major and duties is judged
University / graduate school (including overseas universities)	Judged flexibly, as traditionally done
College of technology (kosen)	Judged in the same way as a university
Certified specialized training college course (certified by the Minister of Education)	Judged flexibly
Other specialized training college courses and advanced courses	A considerable degree of relevance is required

The education requirement itself sits in item 1 of the “Engineer/Specialist in Humanities/International Services” section of the Ministerial Ordinance on Criteria, where clause (ro) requires “having majored in subjects relating to the relevant technology or knowledge and completed a specialized training college course or advanced course in Japan (limited to cases where the completion meets the requirements specified by public notice of the Minister of Justice).” The provision itself says “having majored in related subjects” — relevance is not a side issue, it is the requirement.

”Diploma of Specialist,” “Advanced Diploma,” and “certified courses” open different doors

The guideline sets out three routes by which a vocational school graduate can satisfy the education requirement: (1) being entitled to use the title of Diploma of Specialist (Article 131-2 of the School Education Act); (2) completing a course or advanced course that confers eligibility for graduate school admission and being entitled to use the title of Advanced Diploma (Article 186-3 of the Enforcement Regulations of the School Education Act); or (3) entering an advanced course as a person recognized as having academic ability equal to or above that of a graduate of a designated specialized course, and completing that advanced course.

Item	Diploma of Specialist	Advanced Diploma
Length of program	2 years or more	4 years or more
Total class hours	1,700 unit hours (62 credits) or more	3,400 unit hours (124 credits) or more
Curriculum	—	Must be systematically organized
Assessment	Grades assessed by examination etc., with completion certified on that basis	Same as left
Further study	Eligibility to transfer into a university	Eligibility for graduate school (courses separately designated by the Minister of Education)

A separate axis is the “certified specialized training college course.” These are courses certified by the Minister of Education under Article 2 of the Regulations on Certification of the Career Development Promotion Program for International Students in Specialized Training College Courses (MEXT Public Notice No. 53 of 2023), with certification requirements including practical classes run in cooperation with companies. The guideline states that for graduates of such courses, “because they have received high-quality education and can be considered able to apply the knowledge they have acquired, the relevance between the subjects majored in and the work to be engaged in is judged flexibly.” Whether your own department is certified can be checked against the list of certified courses published by MEXT.

The practice of proof: matching coursework to duties line by line

Proving relevance takes more than an abstract assertion that “the two are related.” In practice it means matching, one line at a time, the subjects listed on the academic transcript against the duties written in the employment contract and the statement of job duties.

1. Inventory the transcript subject by subject. Look not only at subject names but at credits and grades. Even under a department name like “International Business,” the conclusion differs depending on whether the content is mainly language study or mainly management and trade practice.
2. Break the contractual duties down to the level of actual tasks. Not “sales,” but “reviewing contracts with overseas clients” and “preparing import and export documentation.”
3. Draw lines between subjects and duties, and identify duties that cannot be linked. If unlinked duties make up a large share of the role, the issue becomes one of eligibility for the status of residence itself.
4. Decide how to handle the unlinked portion. Work with the company to either remove it from the role or position and explain it as initial in-house training.
5. Put this correspondence into the statement of job duties in writing. Cite subject names and state concretely where in the work that knowledge is needed.

The guideline states that even where a subject cannot be regarded as directly “majored in,” “where, looking at the content of the coursework as a whole, the applicant can be recognized as having acquired knowledge relating to the work, a comprehensive judgment is made.” The weaker the single-subject match, the more valuable it is to show the whole picture in numbers, that is, in credits. Indeed, a published refusal case records that “the central subject majored in was English, coursework relating to real estate and sales knowledge was minimal, relevance to the subjects majored in was not recognized, and the application was refused” — examiners do look at the weight of credits.

Documents prepared by the employer matter just as much: a company brochure, an organizational chart showing the assigned department, and an explanation of the education, career history, and pay of Japanese employees doing the same work. A published approval case describes an application granted after it emerged that Japanese employees in the same role were science and engineering graduates, that recruitment for the role specified university-level education, and that pay was identical. The question “would this job require a degree of a Japanese employee too?” is strong evidence of professional content.

The most common pitfall is how the employment contract is written

What most often derails these applications is not the education itself, but the wording of the contract.

Note: Under Article 15(1) of the Labor Standards Act and Article 5, item 1-3 of its Enforcement Regulations, “the place of work and matters relating to the duties to be performed (including the scope of change to the place of work and the duties to be performed)” are working conditions that must be stated in writing. This written statement of working conditions is a required document for the Engineer visa application.

Two failures recur here.

First, the description of duties is too abstract. A contract that says only “general position,” “clerical work,” or “sales in general” gives you nothing to link to your coursework. From the examiner’s side, what is not written is simply unknown.

Second, the application form and the contract contradict each other. The application says “translation and interpretation work,” while the employment contract says only “store staff.” Filed in that state, the application invites the question of which one is true. A published refusal case describes exactly this: the worker dispatch contract listed the duties as “store staff,” and when the host company was asked, it explained that the person would handle customer service and sales, so the application was refused.

Never write duties into the application form that do not appear in the contract. If the person really will perform those duties, the contract is what should be corrected. Once consistency is questioned, any explanation tends to look like an afterthought. Other typical failure patterns are collected in Engineer Visa Refusal Cases and Countermeasures: Five Pitfalls.

Facing combinations where relevance is hard to establish

Where the department and the desired role are a poor fit, the available directions are as follows.

Situation	Direction to consider
Only part of the duties links to the coursework	Rebuild the role around the linked duties and make the proportion of peripheral duties explicit
The department name shows no link, but individual subjects do	Build documentation that explains subject by subject and credit by credit, rather than relying on the department name
Moving from a language department into translation or interpretation	Note that subjects that only raise basic Japanese ability are not credited as relevant
Relevance cannot be constructed at all	Consider the ten-year work experience route, or substitution through designated information technology examinations and qualifications

Translation and interpretation work needs particular care. Appendix 3 of the guideline states that even where a transcript contains a substantial number of subjects relating to “Japanese,” those subjects will not be treated as a major in the subjects required for translation and interpretation work if they were taken in order to acquire the technical vocabulary needed to study specialist subjects, if they remain at the level of raising basic Japanese ability such as conversation, reading, listening, and kanji, or if they are “Japanese” classes from which Japanese students in the same course are exempted. The applicant must also actually be capable of the work, and the employer must have sufficient volume of it. For details, see The Engineer Visa for Interpretation, Translation, and International Services Roles. For the wider problem of a gap between major and role, see Mismatch Between Major and Job? Mastering the Engineer Visa Relevance Requirement.

As for the period after relevance has been recognized and work has begun, the guideline states that “for those who have been engaged for approximately three years in work for which relevance was recognized, the relevance of the work they subsequently intend to engage in will be judged flexibly.” Proof at the first job shapes later career choices as well.

Another route: Designated Activities No. 46

For vocational school graduates, a route other than the Engineer visa may also be open: the Designated Activities status supporting the employment of international students (graduates of Japanese universities, commonly called No. 46).

Under the February 2024 revision, those who completed a specialized training college course certified under the Career Development Promotion Program for International Students and obtained the Advanced Diploma were added to the eligible group. Under this status, general service work and manufacturing work that would not be accepted under the Engineer visa may be performed, provided the requirements are met.

Note: On eligibility, the guideline states plainly that “graduates of overseas universities and graduate schools, and those who have completed a specialized training college course or advanced course that is not a certified specialized training college course, are not eligible.” Graduates of courses at non-certified schools are outside the scheme, and a “Diploma of Specialist” alone is not enough. There is also a Japanese language requirement: JLPT N1, or 480 points or more on the BJT Business Japanese Proficiency Test.

Because eligibility changes how the whole career plan is built, please check the requirements at Designated Activities No. 46.

Summary

• The guideline judges the university major-to-duties link “flexibly,” while requiring “a considerable degree of relevance” for specialized training colleges
• Proof means matching transcript subjects against the duties in the employment contract and statement of job duties, one by one
• The most common pitfalls are abstract duty descriptions in the contract and contradictions between the application form and the contract
• Writing duties into the application form that are absent from the contract invites questions about consistency
• Graduates of courses certified by the Minister of Education are judged flexibly, and an Advanced Diploma also opens the Designated Activities No. 46 route
