NIGINTERN is the summer research internship of Japan’s National Institute of Genetics (NIG) in Mishima, Shizuoka. Interns spend about six weeks doing an independent life science project in an NIG lab, then present it at the NIGINTERN Reports Symposium. It is open to students of any nationality who live outside Japan and are in their pre-final year of a bachelor’s or master’s programme. It is also one of the hardest internships in Asia to get: in 2025, six students were picked from more than 1,240 applications.
The Deadline for the NIG internship is 5 January 2027 at noon Japan time (03:00 GMT), based on the 2026 round, which ran from 1 December 2025 to noon on 5 January 2026. Before you apply, know that the funding changed. NIG says the 2026 programme was not fully funded: it paid airfare up to 200,000 yen and travel insurance, while interns paid about 70,000 yen for the guest house, domestic travel and all living costs. Many guides still describe NIGINTERN as fully funded.

NIG internship dates and deadline
NIG publishes a fresh page for each year’s round, usually opening applications on 1 December. The 2026 timeline, from NIG’s application guideline, shows how the year runs:
| Stage | 2026 round | Next round |
|---|---|---|
| Online application opens | 1 December 2025 | 1 December 2026 |
| Deadline (applications and both recommendation letters) | 5 January 2026, noon JST | 5 January 2027, noon JST |
| Results | By the end of February 2026 | By the end of February 2027 |
| Passport copy due from selected interns | Early March 2026 | Early March 2027 |
| Travel arrangements | March to May 2026 | March to May 2027 |
| Internship | 8 June to 17 July 2026 | June to July 2027 |
| Essay, questionnaire and boarding pass stub due | 24 July 2026 | About one week after the internship |
Next-round dates are based on this year’s dates; confirm on the official page when the call opens.
Watch the holiday gap. NIG’s office closed from 27 December 2025 to 4 January 2026, so any question you send over Christmas will not be answered before the deadline. Your two referees also have to submit by the same noon cut-off, at a time when many lecturers are on leave. Ask them in November.
What NIG interns actually do
Each intern joins one host lab and works on an independent research project under the lab’s principal investigator. You work full time, five days a week, on a schedule agreed with your supervisor. Around the lab work, NIG runs lab visits where you can talk to other PIs about their research, and you can attend graduate programme lectures, journal clubs and seminars by NIG and visiting researchers. Japanese language classes are offered too.
At the end, every intern gives an oral presentation at the NIGINTERN Reports Symposium. After you go home, you submit an essay and a questionnaire, plus the stubs of the boarding passes for flights NIG paid for. Interns who complete the programme receive a certificate. NIG warns that failing these duties can lead to reduced financial support or termination, so keep your boarding passes.
You also agree to keep unpublished information you see at NIG confidential. That matters in genetics, where a lab may be months from publishing.
NIG is the home of a graduate programme in genetics, and the internship is partly a recruiting tool. NIG encourages interns interested in its PhD programme to apply, and six weeks in a lab is the best possible preparation for that later application.
NIG internship funding: what is covered and what you pay
NIG’s 2026 page states plainly that, unlike previous years, the programme was not fully funded. Here is the split NIG published:
| Cost | Who paid in 2026 | Notes |
|---|---|---|
| Round-trip international airfare | NIG, up to 200,000 yen | Actual cost between your home institution and Japan. You pay anything above 200,000 yen |
| Travel insurance | NIG | For the programme period |
| Domestic travel (airport to Mishima) | Intern | Earlier guides say NIG covers this; the 2026 page lists it as the intern’s cost |
| NIG Guest House | Intern | About 70,000 yen for 39 nights |
| Food and living costs | Intern | No stipend or daily allowance is listed |
| Visa and passport | Intern | Depends on your country |
Budget for at least the guest house fee, domestic travel and six weeks of food in Japan, on top of any flight cost above the cap. If you fly from West Africa, South America or other far regions, check fares early: a return flight to Tokyo can exceed 200,000 yen, especially if you book late. Ask your university or a local research foundation whether it will cover the gap; a letter of acceptance from NIG helps with that request.
NIG may restore full funding in a later year. Read the funding section of the 2027 page carefully when it appears instead of assuming either version.
NIG internship eligibility: the pre-final-year rule
The rule that disqualifies most applicants is the year of study. You must be in your pre-final year at the time you apply, which means one of these:
| Programme length | Year you must be in when applying |
|---|---|
| 4-year bachelor’s | 3rd year |
| 3-year bachelor’s | 2nd year |
| 5-year programme | 4th year |
| 6-year programme (for example medicine, pharmacy or veterinary) | 5th year |
| 2-year master’s | 1st year |
Other conditions from NIG’s page:
- You must be interested in life sciences.
- You must live outside Japan when you apply. Students already living in Japan cannot apply.
- Any nationality and any country of university is accepted.
- PhD students and students who are not in their pre-final year are not considered.
- The dates are fixed. NIG will not consider requests for a shorter or longer stay.
Final-year students often ask whether they can apply anyway because they will graduate after the internship. They cannot. NIG wants interns who can return to their university for a final year and possibly apply to NIG’s PhD programme afterwards.
Documents for the NIGINTERN application
Everything goes through NIG’s online system. NIG states that materials sent by email are not accepted.
| Document | Requirement |
|---|---|
| Letter of motivation (self-advertisement) | Up to 500 English words |
| CV | In English, education from high school onwards, with your current year of study stated |
| Academic transcript | Latest undergraduate or postgraduate transcript, scanned. Add an English or Japanese translation if needed. Merge several pages into one file |
| Two recommendation letters | From teachers. You enter both recommenders’ names and emails at registration; they receive an email and upload through the recommender page |
| Registration details | Current postal address, field of interest and preferred host lab |
NIG advises using an institutional email address, because free accounts such as Gmail may not receive its messages reliably. If you are selected, you must send a copy of a valid passport by early March, so apply for a passport now if you do not have one.
How to apply for the NIG internship
- Read the host lab list: NIG posts the participating labs with each year’s call. Pick the lab whose work you can describe in your own words.
- Ask two teachers in November: confirm they will upload before noon JST on 5 January, and give them your CV and a short note on the lab you chose.
- Register on the online system: from 1 December, using your university email. Enter your recommenders’ details at this stage, which triggers their invitation email.
- Upload your documents: motivation letter, CV and a single merged transcript file.
- Check your recommenders’ status: chase them gently in late December if letters are missing. Remember the NIG office is closed over the New Year.
- Submit before noon JST on 5 January: that is 03:00 GMT, which is still the night of 4 January in the Americas.
- Wait for results: by the end of February. The host lab PI may contact you during screening, so watch your inbox.
How to write the NIGINTERN motivation letter
NIG calls this document a self-advertisement, and that is a useful hint. In 500 words you need to show a selector, often the PI of your chosen lab, that you understand their research and would use six weeks well. NIG has no separate research proposal, so the letter also carries your research idea.
- The question (about 100 words): the biological problem that interests you and why, tied to the host lab’s recent work.
- Your preparation (about 200 words): lab skills you have actually used, such as PCR, cell culture, microscopy, or R and Python for sequence data. Describe one project and what you found.
- Your plan (about 120 words): what you would like to try in six weeks and what you hope to learn.
- Your direction (about 80 words): how this fits your next step, for example graduate study in genetics, at NIG or elsewhere.
A sample opening line: “While sequencing mitochondrial DNA from local cichlid populations for my third-year project, I became curious about how new species keep their genomes apart, which is the question your lab studies in Drosophila.” Swap in your own project and the lab you are applying to. One honest, specific sentence like this tells the PI more than a paragraph about a lifelong passion for science.
With six places and more than a thousand applicants, a letter that could be sent to several labs will not get far, so name the lab and refer to its published work.
NIG internship selection process
NIG describes selection as highly competitive and does not publish its criteria in detail. What the official pages do show:
- Only complete applications submitted before the deadline, with both letters, are screened.
- The prospective host PI may contact you during screening, so a short email or video call can be part of the process.
- Results come out by the end of February. NIG lists successful applicant numbers on its site.
- NIG does not answer individual questions about selection status or results, so check the FAQ instead of emailing.
- Selected interns send a passport copy in early March, and NIG arranges travel between March and May.
Common NIGINTERN mistakes
- Applying in your final year. You must be in your pre-final year when you apply.
- Applying while living in Japan, including as an exchange student there.
- Writing a motivation letter that could go to any lab.
- Registering with a Gmail address and missing NIG’s emails.
- Assuming referees will remember during the holidays. Both letters are due at the same noon cut-off as your application.
- Planning around full funding. In 2026 you paid for housing, domestic travel and food.
- Asking NIG for a shorter stay because of exams. The dates are fixed.
NIGINTERN vs other research internships in Japan and abroad
| Programme | Country | Length | Main funding | Who it suits |
|---|---|---|---|---|
| NIGINTERN | Japan | About 6 weeks, June to July | Airfare up to 200,000 yen and insurance (2026) | Pre-final-year life science students |
| UTRIP (University of Tokyo) | Japan | 6 weeks, late June to early August | 140,000 to 170,000 yen one-time allowance, free housing | Bachelor’s students in natural sciences, year 2 or later |
| OIST Research Internship | Japan | 4 to 6 months | 2,400 yen per working day, flight, housing | Final-two-year bachelor’s, master’s, graduates |
| Mitacs Globalink Research Internship | Canada | 12 weeks | Funded; amounts vary by country | Undergraduates in 23 partner countries |
| METI Japan Internship Program | Japan | Varies by course | Flight, housing, 3,000 yen a day for the in-person course | Final-year students and graduates from DAC-list countries (company internship) |
If NIGINTERN confirms you want a research career in Japan, the MEXT scholarship is the usual route to a funded master’s or PhD there.
Who should apply, and who should not
Apply if you are in your pre-final year, you have done some hands-on lab or computational biology work, and you can name a host lab whose research you would like to join. It is a good fit for students thinking about a PhD in genetics or molecular biology, in Japan or anywhere else.
Think twice if you cannot cover roughly 70,000 yen for housing plus food and domestic travel for six weeks, if your exams fall in June or July, or if your interest is in clinical medicine rather than basic research. With six places a year, I would also apply to UTRIP or Mitacs in the same season rather than putting everything on NIG.

Sources and updates
Checked on 25 October 2026 against the National Institute of Genetics NIG-INTERN page (2026 dates, eligibility, funding split, number selected) and the NIG-INTERN application guideline (documents, word limit, recommendation process, results and travel timeline). The full-time schedule, confidentiality rule and Japanese classes are listed in NIG’s programme conditions page, which is linked from the intern page; read it before you accept an offer. Older guides describe the internship as fully funded with free guest house housing; NIG’s 2026 page says otherwise. We will update this guide when NIG posts the 2027 call.
I am Jude Chinecherem, a final-year MBBS student at the University of Nigeria, Nsukka. I know what it feels like to want an education your family cannot afford. When my parents could not pay for my schooling, I had to learn how to find scholarships and work the system out on my own, with nobody to guide me. I came out the other side, and now I share everything I learned so the next student does not have to figure it out alone. This is the advice I wish someone had given me back then.
