Target companies that already hire engineers in English, apply through their global careers pages and university career services, and plan the visa with your university early. The right visa depends on the internship's length, whether it is paid and whether your university grants credit. Japanese helps a lot, but some tech teams work in English.
What people tell me
I am a computer science student and I would love to do an internship in Japan, partly to see whether I would want to work there after graduating. I do not speak much Japanese yet. I do not know which companies take international interns, how the visa works, or whether it is even realistic without being enrolled at a Japanese university.
A composite of the messages behind this question, with personal details left out.
Key takeaways
- Look for companies whose engineering teams already work in English.
- The visa depends on length, pay and university involvement; plan it with your university.
- Students already studying in Japan have more options, including part-time work with permission.
- Some basic Japanese makes daily life and many roles much easier.
- Apply early: Japanese hiring runs on a structured calendar.
Is it realistic?
Yes, but it takes more planning than an internship at home. Japan has a growing number of tech companies whose engineering teams work in English, and some run internships open to international students. The two things that make or break it are finding those companies and getting the visa right.
Two different situations
| Studying outside Japan | Already studying in Japan | |
|---|---|---|
| Typical route | A structured internship arranged with the company and your university | Internships at Japanese companies, often during breaks |
| Visa | Depends on length, pay and whether your university grants credit | Your student status, with permission for part-time work |
| Main challenge | Paperwork and the university agreement | Language and the Japanese recruiting calendar |
If you are studying outside Japan, a paid internship usually needs a Designated Activities status of residence, which generally requires an agreement between your university and the host company, and is limited in length. Short, unpaid programmes can fall under other categories. The rules are specific, so confirm your case with the company, your university and the Japanese embassy or immigration guidance before you commit.
If you are already a student in Japan, you can generally work part-time, up to 28 hours a week during term, once you have permission to engage in activities outside your status. Many international students gain experience this way.
Which companies to look at
- Japanese tech companies with English-speaking engineering teams. Some large internet companies and fast-growing startups hire engineers from abroad and run their engineering in English.
- Global companies with offices in Japan. Their internship programmes often recruit through global careers pages.
- Startups. Smaller companies may be more flexible about language and timing.

How important is Japanese?
For English-first engineering teams, not essential for the work itself. For daily life, team lunches and many other companies, it makes a big difference. Even basic conversational Japanese shows commitment and widens your options. If you are serious about working in Japan after graduating, start now. It is a long-term investment.
What to prepare
- A strong project portfolio. Language barriers make your code and your README do more of the talking.
- An English CV in the usual one-page format, plus willingness to fill in company-specific forms.
- Problem-solving practice. Many internationally minded tech companies run coding assessments. The DSA roadmap is a good structure.
- A talk with your university's international or career office about credit and internship agreements.
Timing
Japanese companies often recruit on a structured calendar, and some internship programmes open months in advance. Start researching at least six to nine months before the dates you want, and keep a simple tracking sheet of programmes and deadlines.

Other routes into Japan
- Exchange semesters at a Japanese university, which make local internships easier. Study in Japan is the official starting point.
- Remote internships with Japan-based companies, which build a connection without a visa.
- Research internships through university labs.
