Japanese for Researchers and Academics Moving to Japan
Most international researchers in Japan do their science in English, but they still need Japanese for everything around it: university administration, lab life, safety rules, grant and HR paperwork, seminars with Japanese students, and life outside the campus. A realistic goal for a postdoc or visiting researcher is conversational Japanese plus reading the key words on forms and notices. Faculty planning to stay long-term usually need much more, because committee work, teaching and departmental meetings are often in Japanese. This guide explains what to learn, in what order, and how to fit it around research.
Where researchers meet Japanese
| Situation | How much Japanese it needs |
|---|---|
| Your own research and papers | Usually none. International publishing is in English. |
| Lab life | Daily greetings, lab rules, safety notices, ordering supplies, chatting with students who may be shy about speaking English. |
| University administration | Contracts, expense claims, travel reports and internal systems are often Japanese-first, with partial English support. |
| Seminars and department meetings | Varies by department. Many are mixed or fully in Japanese. |
| Teaching and supervision | Depends on the programme. English-taught courses are growing, but Japanese helps you support students. |
| Committee and faculty duties | Often in Japanese, especially for permanent faculty. |
| Life outside the lab | Housing, city hall, children’s schools, the doctor. See how much Japanese you need to live in Japan. |
What to learn first
- Kana and survival Japanese before you arrive, so your first weeks of paperwork and settling in are easier. See moving to Japan: a first-month checklist.
- A self-introduction for the lab. On your first day you will introduce yourself to the lab, often at a lab meeting. A short, polite introduction in Japanese makes a strong first impression. See how to introduce yourself in Japanese.
- Lab vocabulary and notices. 実験 (experiment), 試薬 (reagent), 廃液 (waste liquid), 安全講習 (safety training), 締切 (deadline), 申請 (application), 精算 (expense settlement).
- Workplace manners. Hierarchy between professors, assistant professors and students, how to ask the lab secretary for help, and the habit of reporting and consulting. See Japanese workplace culture.
- Email and chat in Japanese for administrative staff, who will appreciate even simple Japanese. See business emails in Japanese.
Lab culture: what surprises newcomers
- Students may be reluctant to speak English, not because they can’t, but because they worry about mistakes. A few words of Japanese from you often breaks the ice.
- Lab meetings are formal in some labs, with set reporting formats and a clear order of who speaks.
- The secretary is central. Lab and department secretaries handle much of the administration, and a good relationship with them makes life easier.
- Year-end and welcome parties (忘年会, 歓迎会) are part of lab life and a good chance to connect.
Fitting study around research
Research schedules are unpredictable, with experiments that overrun, deadlines and conference travel. What works for most researchers is short, flexible lessons rather than fixed classes: two lessons a week online at a time you choose, focused on what you need next, whether that is a lab presentation, a meeting with administration or your child’s school letter. Some universities offer free Japanese classes for staff, which are worth joining for the basics; private lessons then fill the gaps classes can’t, such as speaking practice and your own documents.
