IT Jobs in Japan for Foreigners: Roles, Visa Fit and How to Get Hired

The main types of IT roles

Software developers are the largest group: web and mobile application engineers, backend engineers, and engineers working on business systems for banks, retailers, manufacturers and government. In-house product companies build and run their own services, while system integrators (SIer) build systems for clients, often in large projects with many subcontractors.

Bridge system engineers (ブリッジSE) connect Japanese clients with development teams abroad, often in Vietnam, China, India or the Philippines. The work is part engineering, part translation of requirements and part project management, and it usually needs business-level Japanese plus your native language. Infrastructure engineers build and operate servers, networks and cloud environments; many start in monitoring or operations and move up to design and construction. QA and test engineers design test cases, run manual and automated tests and report defects.

There are also adjacent roles: IT support and helpdesk, data analysis, pre-sales engineering and technical writing. Whether a given role fits a work status depends on the actual duties, not the job title, so read the job description closely.

English-speaking teams vs Japanese-speaking teams

English-speaking teams exist mainly at global tech companies, startups aimed at international markets, and some larger Japanese product companies that have made English their engineering language. They are concentrated in Tokyo, competition is strong, and they usually expect solid experience and a track record you can show. Japanese ability is often listed as a plus rather than a requirement, but it still helps with daily life and with working alongside Japanese colleagues outside engineering.

Japanese-speaking teams make up most of the market, especially at system integrators and in-house IT departments. Specifications, meetings and client communication are in Japanese, and many employers ask for JLPT N2 or equivalent, sometimes N1 for client-facing or bridge work. In exchange, the number of openings is far larger and junior candidates have more room to enter.

Many people combine the two: they start in a team where English or their native language is enough, keep studying Japanese, and move toward Japanese-speaking roles as their level rises. On OlaJob you can filter for English-speaking workplaces and for the JLPT level each job requires.

How IT work fits the Engineer/Specialist status

Most foreign IT professionals in Japan work under the Engineer/Specialist in Humanities/International Services status (often called 技人国). For engineering work, the review generally looks at whether the job content is specialized IT work and whether it relates to what you studied, for example a university degree in computer science or a related field, or a qualifying diploma from a Japanese vocational school in a related subject.

There are other paths to meeting the requirement. People who have passed or hold certain IT qualifications designated by the Minister of Justice, which include some Japanese national IT exams and some exams in other countries, can be treated as meeting the education requirement for IT work. Long professional experience in the field can also count, but the rules on how many years and how it must be proven are specific, so check the Immigration Services Agency's current guidance before relying on it. Your own case depends on your documents, and no degree, exam or job offer makes approval certain.

Employers also have to explain that the duties are specialized. Pure operations work such as simple data entry or repetitive manual checking may be questioned, while design, development, testing with engineering judgment and infrastructure construction are usually easier to explain. The final decision always rests with the Immigration Services Agency of Japan.

Highly Skilled Professional points: a later option

Experienced engineers sometimes look at the Highly Skilled Professional status, which uses a points system covering education, work experience, annual salary, age, Japanese ability and certain qualifications. If your total passes the threshold, the status comes with benefits such as a longer period of stay and a possibly shorter route to permanent residence.

Treat it as something to calculate carefully rather than assume. The point table and conditions are published by the Immigration Services Agency and can change, and salary and qualification points depend on how your documents are assessed. Many people start on the Engineer/Specialist status and consider the points system later, once their salary and experience have grown.

Presenting your GitHub and portfolio

Japanese hiring still relies heavily on the resume (履歴書) and the career history document (職務経歴書). Your GitHub and portfolio work best as evidence that supports those documents, not as a replacement. In the career history, list each project with its period, team size, your role, the technologies used and what you personally delivered.

On GitHub, a few well-documented repositories beat many half-finished ones. Pin the projects you want reviewed, write a clear README with the purpose, setup steps and screenshots, and keep commit history readable. If most of your work is under confidentiality, write short case descriptions instead and never upload client code.

For Japanese-speaking companies, a README or project summary in Japanese is a strong signal, even if it is short. For English-speaking teams, expect technical interviews, coding tests or take-home assignments, and be ready to explain your design choices out loud.

• Pin two to four repositories that match the jobs you are applying for
• Write READMEs that explain the problem, your approach and how to run the project
• Link your portfolio from your resume and career history document
• Prepare a short, clear explanation of one project for interviews
• Remove secrets, API keys and any client or employer code before publishing

SES and dispatch-style contracts: what to check

A large share of IT jobs in Japan are at SES (system engineering service) companies or IT staffing firms. You are employed by one company but work at a client site or on a client project, often moving between projects every few months. This can be a real entry point for junior engineers, but conditions vary widely.

Before signing, ask which projects you will realistically be placed on, who gives you daily instructions, what happens to your salary between projects (待機, waiting time), and how your skills will be developed. Being told to do tasks unrelated to your field, or being left without projects for long periods, can create problems not only for your career but also when you renew your status, because the review looks at the work you actually do.

Worker dispatch (労働者派遣) is a legally separate arrangement with its own rules, and the dispatching company must hold a license. If a contract is called outsourcing but the client directs you like its own employee, that may be a sign of disguised contracting (偽装請負). The Ministry of Health, Labour and Welfare publishes information on dispatch rules, and labor bureaus can advise if something seems wrong.

A realistic plan for getting hired

Decide first which market you are aiming at: English-speaking product teams, Japanese-speaking companies, or bridge roles that use your native language. Your study plan, resume language and target companies all follow from that choice.

Keep your documents ready early: degree certificate and transcript, proof of any IT qualifications, and employment certificates from past employers that describe your duties. These matter for the status application as much as for the hiring decision. Then apply in batches, track each application, and use every interview to improve your explanation of your projects.
