The field: CS, informatics, data science and AI in Japan
In Japan, computer science is often housed under "informatics," "information science and technology," or "computer science and engineering." The field covers the usual core — algorithms, systems, software engineering, networks, databases — plus fast-growing areas like artificial intelligence, machine learning, data science, human-computer interaction and computer graphics.
This is a dedicated field guide for CS/IT within Japan specifically. It is distinct from region-wide "best universities for engineering and technology" comparisons: here the focus is on how the CS field is taught and entered in Japan, and where English-medium study is realistic.
Where English-taught CS/informatics degrees exist
At undergraduate level, the University of Aizu — Japan's first university to specialise in computer science and engineering — runs an all-English ICT program, and a handful of other universities offer English-medium informatics tracks. At graduate level, English-medium options are broader: the Institute of Science Tokyo and other national research universities run master's and doctoral study in information science and engineering in English.
Availability changes and many CS programs are still Japanese-medium, so confirm on each university's official department page whether your intended course runs in English for your intake year. Use the Study in Japan portal's school search as a starting point, then verify on the university site.
- Undergraduate: University of Aizu (all-English ICT) and a few others
- Graduate: broader English-medium informatics/CS at research universities
- Always confirm language of instruction on the official department page
Entry expectations: background, tests and the research route
For undergraduate CS, expect a strong mathematics background; universities may use the EJU (Mathematics and Science, available in English) plus their own documents or exam. Prior programming is often welcome but not always required — check each program.
For a graduate CS/AI degree, the research-supervisor route dominates: identify a lab (for example in machine learning, systems or data science), prepare a research plan, and apply with your transcript and an accepted English test such as IELTS or TOEFL. Some programs consider GRE. Requirements differ, so verify each program's official admissions page rather than assuming a common standard.
- Undergraduate: maths-heavy; EJU (Maths/Science in English) plus university documents
- Graduate: lab fit + research plan + English test (IELTS/TOEFL); some accept GRE
- Programming background helps but requirements vary — confirm per program
How coursework and research labs are structured
Japanese CS education is strongly lab-centred, especially from the later undergraduate years and throughout graduate study. Students join a research lab (kenkyushitsu) led by a professor and work closely with the group on projects, seminars and papers.
Undergraduate years typically build core theory and programming before specialisation; master's study is research-intensive with a thesis. If you want a research career or a PhD, the lab you join matters as much as the university name — read faculty pages and recent lab publications to judge fit, and confirm current supervisors and openings on the official site.
Cost, scholarships and verifying the details
Tuition differs between national and private universities and changes yearly, so this guide does not quote fees — check the current numbers on each university's official page. Funding routes include the MEXT scholarship, JASSO support and university awards, each with its own official eligibility rules and deadlines.
As always, verify amounts and deadlines on the official scholarship pages, and treat any "guaranteed admission," "guaranteed scholarship" or paid-placement offer as a scam. Legitimate programs never sell a seat.
- Verify tuition on the official university page (national vs private differ)
- MEXT / JASSO / university scholarships — check official eligibility and deadlines
- No legitimate program guarantees admission for a fee
Career direction in Japan's tech and IT industry (neutral)
Japan has a large IT and technology sector spanning software, electronics, robotics, gaming, telecoms and research, and universities usually provide structured job-hunting support. Graduate degrees are common for research and specialist R&D roles.
Working in Japan after study depends on Japan's official immigration rules for work status, which are separate from student status and change over time. This is general information, not immigration advice — verify the current rules on the official government source. This guide makes no salary or hiring guarantees; outcomes depend on your skills, field, Japanese ability and employer.
Frequently asked questions
Are there English-taught computer science degrees in Japan?
Yes — at undergraduate level the University of Aizu runs an all-English ICT program and a few others exist, while graduate CS/informatics has broader English-medium options at research universities. Many CS programs are still Japanese-medium, so confirm the language on the official department page for your intake year.
What background do I need for CS in Japan?
A strong mathematics foundation is expected; prior programming helps. Undergraduate entry often uses the EJU (Maths and Science, available in English) plus university documents, while graduate entry centres on lab fit and a research plan. Check each program's official requirements.
How do I apply for a master's or PhD in AI or data science in Japan?
Identify a professor whose lab matches your interest (for example machine learning or data science), prepare a research plan, and apply with your transcript and an accepted English test. Some programs also consider GRE. Verify the exact steps on the official program page.
Do I need Japanese to study CS in Japan?
Not to complete a genuinely English-medium degree, but Japanese is useful for daily life and internships, and most universities offer Japanese classes. Confirm the English-test requirement and any Japanese expectation on the program page.
