Graduate Program in Japan: A Guide for International Students

A graduate program in Japan is structured differently from the model most international applicants have in mind, and the differences are not cosmetic. They change how you get in, who decides, what your two or three years look like, and what the degree is worth at the end.

Applicants who understand the structure apply well. Applicants who apply as though Japan were the United States with different scenery tend to make the same handful of avoidable mistakes — approaching the admissions office instead of a professor, underestimating the entrance examination, and discovering the laboratory system only after they have committed to it.

This guide explains how the system actually works. For choosing between programmes, see our guide to choosing a master’s programme in Japan; for the full two-year budget, see our cost guide to a master’s in Japan.

Why is the laboratory the unit that matters?

Start here, because everything else follows from it.

In a Japanese graduate programme in the sciences, engineering, agriculture and much of medicine, you do not simply enrol in a department. You join a laboratory — a kenkyushitsu — headed by a professor and made up of master’s students, doctoral students, and sometimes postdoctoral researchers and technical staff.

The laboratory is your academic home and, in practice, a large part of your social one. Its seminars are compulsory. Its group meetings are where your work is scrutinised. Its professor determines your research direction, in many cases your funding, and your reference when you leave.

The practical consequences:

• Choose the laboratory, not the university. Two labs in the same department can differ enormously in funding, working language, supervision style and where their graduates end up.
• Contact the professor before you apply. This is expected, not presumptuous. A short, specific email about your interests and their recent work is the normal opening move, and an application backed by a professor who wants you is a different application. Our guide to faculty approval versus scores in Japanese applications covers how to write that email.
• Ask where their graduates went. By name, over the last few years. It is the single most informative question you can ask, and a specific answer tells you what the lab is a route into.

How does the model change by field?

The laboratory model is the science and engineering version. It is not universal, and applying to a humanities programme as though it were will not work.

The practical implication is that most advice about “graduate study in Japan” is advice about the laboratory model. If you are applying to a professional graduate school, much of it does not apply to you — and if you are applying to a science programme, the parts about taught coursework do not apply either.

What is the entrance examination like?

Most Japanese graduate schools admit through their own examination, set and marked by the department.

A typical examination covers subject knowledge in your field, frequently mathematics for science and engineering, sometimes a foreign-language component, and almost always an interview. It runs on the department’s own calendar, often with a summer sitting for an autumn or following-spring intake.

This is the step international applicants most consistently underestimate. It is not a formality and it is not a light screen. Departments frequently publish past papers or supply them on request — get them and treat them as the syllabus, because they are the most accurate statement of what the department expects you to know.

Some programmes, particularly English-taught ones designed for international intake, admit on documents and interview without a written examination. Check which regime applies to you rather than assuming.

What is the research-student route?

A distinctively Japanese option, and one that solves a number of problems.

A kenkyusei is a non-degree research student attached to a laboratory. You are enrolled at the university, you work with the group and you may attend classes, but you are not on a degree programme and earn no credits towards one. Many international students spend six months to a year in this position and then sit the entrance examination for the master’s.

• Why people use it: to prepare for the entrance examination with the department’s own materials and people; to improve their Japanese; to confirm the laboratory is a good fit before committing years to it; or because their academic background does not map cleanly onto the examination.
• What it costs: research students pay their own, lower fee scale — Kyoto University, for example, charges ¥29,700 a month plus an ¥84,600 admission fee. Scholarships aimed at degree students often do not cover this period, so a self-funded year is a real cost. Establish what is available before you commit.

Our Kyoto University master program guide walks through how one university runs this route in practice.

When does the academic year start?

Japan’s academic year begins in April, and that remains the main intake. Many universities now also run a September or October intake, particularly for English-taught and international programmes.

The implication is that application deadlines are spread across the year and vary by department rather than following one national calendar. Two departments at the same university can have entirely different timelines. Check each one individually, and early.

How long are the degrees?

• Master’s: two years. Research-first in the sciences and engineering, with a thesis; more taught content in professional and social science programmes.
• Doctorate: three years after a master’s. Research from the start — no substantial coursework phase and no qualifying examination in the American sense. Faster than the five-to-six-year American model, and narrower in formal training.
• Integrated programmes: some universities offer combined master’s-doctoral tracks, typically five years, which can change the funding position favourably.

How is graduate study funded?

The usual sources are MEXT (by embassy or university recommendation, one route per year), university tuition reduction or exemption, the JASSO Honors Scholarship on university nomination, laboratory assistantship income, and foundation awards — usually in combination. Our guide to the four routes to a Japan master’s scholarship explains each.

Two structural points catch people out. First, much university funding is decided after you arrive, so arriving self-funded and securing a tuition reduction or nomination in your first year is a normal path — budget for the opening months accordingly. Second, laboratory money never appears on any scholarship list; it is obtained by asking a professor directly.

What about language?

English-taught graduate programmes are real and reasonably numerous, concentrated in engineering, science, and international policy and business at the larger universities. Japanese-taught programmes generally expect JLPT N2 or above and open the full range of institutions. The laboratory’s working language is a third, separate question. Many labs at major universities function in English regardless of the programme’s formal language; many do not. Seminars and group meetings are where this actually bites, so ask the professor.

What sequence works?

1. Identify two or three target laboratories. Search departmental pages and recent papers for labs whose active work matches your interests — research alignment, not rankings.
2. Write to each professor. Keep it short and specific: your background, a research idea, and why their lab in particular.
3. Ask the practical questions. Are they taking international students? What is the day-to-day working language? Are there RA or TA positions? Where did recent graduates go?
4. Get the past examination papers. From the department office or its website, and prepare against them.
5. Choose your entry track. Direct entry to the master’s, or a research-student period first.
6. Apply on the department’s own deadline, with a research proposal realistic enough to defend in an interview.
