Quick Read
- Internships in Japan run via named research programs (OIST, RIKEN, KEK), professor outreach, or company internships.
- OIST pays JPY 2,400/day (Rs.1,451) plus free flights, housing, and visa support.
- KEK selects only 20-25 students globally each year for its 8-week physics internship.
- JSPS’s Summer Program excludes India; only their Postdoctoral Fellowship is open to Indians.
- Budget: Rs.70,000-90,000/month for living costs on top of any internship stipend.
Can Indian Students Get Internships in Japan?
Yes, through three main routes, each with a different application process and visa mechanism.
- Named research institute programs, like OIST, RIKEN, and KEK, place you in a Japanese lab for 2 to 6 months, fully funded, with no existing Japan visa required beforehand.
- Independent professor outreach, contacting a specific lab or PI directly, works for institutes without a formal internship portal.
- Company internships, at firms like Sony, Toyota, Rakuten, and SoftBank, follow Japan’s standard visa framework and are typically shorter and less research-focused.

End-to-End Application Support
Note: Not every internship in Japan for Indian students is actually open to India. JSPS's well-known Summer Program, for example, restricts applicants by nationality, a detail that most listicle-style articles miss. Verify eligibility on the program's own page before investing weeks in an application.
OIST Research Internship: The Most Accessible Funded Route
OIST runs the most genuinely open research internship on this list: no nationality restriction and no IELTS/TOEFL requirement.
| Detail | Information |
|---|---|
| Eligibility | Final 2 years of a Bachelor's, any year of a Master's, or recent Bachelor's/Master's graduate. PhD students and graduates are not eligible. |
| Nationality | Open to all countries, including India |
| Duration | 3 to 6 months |
| Stipend | JPY 2,400/day (Rs.1,451), non-taxable, weekends excluded |
| What's covered | Round-trip airfare, accommodation, commuting allowance, visa support (Certificate of Eligibility assistance) |
| Application fee | JPY 5,000 (Rs.3,024), non-refundable |
| Fields | Physics, chemistry, biology, neuroscience, mathematics, computational science, marine science, engineering |
| Deadlines | Mid-October (Spring cycle) and mid-April (Fall cycle), tentative each year |
Exchange rate: Rs.0.6047/JPY (August 2026). Verify current rate before budgeting.
Currently enrolled students need home institution approval before applying, and your academic background must align with your chosen OIST research unit. Since OIST has no departments, interdisciplinary applicants (a CS student interested in marine biology data, for instance) are genuinely welcome.
Counselor insight: The JPY 2,400/day stipend looks small in isolation, but since housing, flights, and commuting are already covered, the amount is discretionary spending money, not your actual cost of living. Don't compare it directly to a paid company internship salary.
RIKEN Internships in Japan: Multiple Programs, No Single Application Route
RIKEN is Japan's largest research institution, and unlike OIST, it doesn't run one central internship portal. Each RIKEN centre manages its own program independently.
| Program | Location | Duration | Stipend | Level |
|---|---|---|---|---|
| RIKEN CBS Summer Program | Tokyo (Wako) | 2 months (Plan A) or 5-day lecture course (Plan B) | JPY 5,200/day (Rs.3,144), ~JPY 156,000/month | Advanced UG to postdoc; highly competitive, grad-oriented |
| RIKEN IMS Summer Internship | Yokohama | Summer, variable | JPY 3,000/day (Rs.1,814) | UG and Master's, biomedical/immunology focus |
| RIKEN RIH Internship | Kyoto | 4 or 8 weeks | Varies by placement | UG and grad, robotics focus |
| RIKEN IPA (International Program Associate) | Varies | Up to 3 years | Living allowance + housing up to JPY 70,000/month rent (Rs.42,329) | PhD students only; requires your university to hold a joint graduate school agreement with RIKEN |
Exchange rate: Rs.0.6047/JPY (August 2026). Verify current rate before budgeting.
Note: RIKEN CBS is described by past applicants as "grad or even postdoc oriented" despite technically accepting undergraduates; your project description needs to be exceptional to compete against Master's and PhD-level candidates.
Unlike the summer programs above, RIKEN IPA is a multi-year PhD funding mechanism and only works if your home university already has, or is entering, a joint graduate school agreement with RIKEN. Check with your department directly.
KEK Summer Student Program: Highly Selective, Physics-Focused
KEK (High Energy Accelerator Research Organization) runs the most competitive internship named on this list, for students interested in particle physics, nuclear physics, or accelerator science.
| Detail | Information |
|---|---|
| Eligibility | Latter half of undergraduate or early Master's; PhD students not eligible |
| Nationality | Open to international and Japanese students |
| Duration | Up to 8 weeks (4 weeks for theory-track projects) |
| Stipend | JPY 1,500/day (Rs.907) |
| What's covered | Round-trip airfare, dormitory accommodation, domestic travel between Tokyo airports and campus |
| What's not covered | Visa fees and medical insurance, arranged independently |
| Selection | Only 20-25 students selected globally each year |
| Application fee | None |
Exchange rate: Rs.0.6047/JPY (August 2026). Verify current rate before budgeting.
Read our dedicated KEK Summer Student Program guide for the full application walkthrough.
Counselor insight: With only 20-25 global selections, KEK is arguably harder to get into than most named US or European research internships on a per-seat basis. Dynamics, electromagnetism, and quantum mechanics are desirable, not mandatory; applicants without this coursework should target materials science or computing tracks instead.
JSPS Routes for Indian Students: What's Actually Open to You
This field is where accuracy matters most and where most competitor content gets it wrong. JSPS runs several distinct programs, not equally open to Indian nationals.
| JSPS Program | Open to India? | Level | Duration | Stipend |
|---|---|---|---|---|
| JSPS Summer Program | No, it's restricted to UK, French, German, Canadian, Swedish, and US citizens | Graduate students and postdocs | 2 months | JPY 534,000 total (Rs.3.23L) + round-trip airfare + insurance |
| JSPS Postdoctoral Fellowship (Standard) | Yes, open to all nationalities with diplomatic ties to Japan | Postdoctoral researchers (PhD within 6 years, or PhD expected within 2 years) | 12-24 months | ~JPY 362,000/month (Rs.2.19L/month) research grant |
| JSPS International Fellowships (broader category) | Yes, criteria vary by subcategory. | Researchers across career stages | Varies | Varies by subcategory. |
| ICSSR-JSPS Joint Research Call | Yes, but for established faculty team leaders, not students | Faculty-level joint research projects | Project-based | Covers international airfare + research costs (project grant, not a personal stipend) |
Exchange rate: Rs.0.6047/JPY (August 2026). Verify the current rate before budgeting.
Note: If you've seen "JSPS Summer Program" listed alongside OIST, RIKEN, and KEK in a generic scholarship roundup, that listing is incomplete. JSPS's own eligibility page restricts the Summer Program to citizens of six specific countries, and India isn't one of them. Without a PhD, no current JSPS route is genuinely open to you; the realistic pathway starts once you hold, or are about to complete, a doctorate.
Counselor insight: Don't spend outreach time on a JSPS Summer Program application as an Indian undergraduate or Master's student; it will be rejected on nationality grounds regardless of academic strength. Treat OIST, RIKEN, or KEK as your near-term route, and revisit JSPS's Postdoctoral Fellowship at the PhD-completion stage.
Other Named Research Internships in Japan Worth Knowing
- NIGINTERN (National Institute of Genetics): A structured genetics research internship under Japan's Ministry of Education, with the application window typically opening late November.
- Independent professor outreach: For institutes without a formal portal, identify 10-15 professors whose recent published work matches your interests, and send a specific, non-generic email referencing their work, using the same approach as for DAAD WISE or Max Planck.
What an Internship in Japan Actually Costs You Monthly
Named programs cover flights and housing, but your daily stipend rarely covers everything. Here's what Japan actually costs.
| City | Monthly Cost (excl. rent) | Typical Rent (1-room) | Total Realistic Budget |
|---|---|---|---|
| Tokyo | JPY 130,000-150,000 (Rs.78,611-90,705) | JPY 60,000-100,000 (Rs.36,282-60,470) | Rs.1.15L-1.51L/month |
| Osaka | JPY 110,000-130,000 (Rs.66,517-78,611) | JPY 45,000-70,000 (Rs.27,212-42,329) | Rs.93,729-1.21L/month |
| Fukuoka/Sapporo | JPY 90,000-110,000 (Rs.54,423-66,517) | JPY 35,000-55,000 (Rs.21,165-33,259) | Rs.75,588-99,776/month |
Exchange rate: Rs.0.6047/JPY (August 2026). Verify the current rate before budgeting.
Read our full guide on the cost of living in Japan for international students for a city-level breakdown.
If you're on a named program like OIST or KEK, accommodation is covered, so your stipend mainly needs to stretch across food, transport, and personal spending; realistically, JPY 30,000-50,000/month (Rs.18,141-30,235) even in Tokyo. If arranging an internship independently, budget the full figures above; Okinawa and regional cities track closer to the Fukuoka/Sapporo range.
Counselor insight: Students on KEK or RIKEN stipends sometimes assume the daily allowance covers a full month. It won't, especially in Tokyo. Bring a modest buffer from home, since the allowance only covers housing, not an independent living budget.
Company Internships in Japan for Indian Students: A Different Visa Track Entirely
If you target a company internship instead (at Sony, Toyota, Mitsubishi, Rakuten, or SoftBank), the visa mechanics change completely.
| Internship Type | Visa Required | Maximum Duration |
|---|---|---|
| Unpaid, part of your degree curriculum, 90 days or less | Temporary Visitor | 90 days, not extendable |
| Unpaid, part of your degree curriculum, over 90 days | Cultural Activities | Up to 1 year, capped at half your total program length |
| Paid (any remuneration), part of your degree curriculum | Designated Activities | Up to 1 year, capped at half your total program length |
| Already on a Student visa, doing a paid internship | Permission to Engage in Activity Other Than That Permitted | Subject to your 28 hrs/week cap unless you qualify for an exception |
Note: Receiving any stipend or wage is legally classified as "work," regardless of amount. A company describing a paid role as an informal "internship" doesn't exempt you from needing the correct visa.
Adding a Paid Internship On Top of Your Student Visa
If already on a Student visa, the default work-hour cap for adding a paid internship is 28 hours a week, extendable to 8 hours a day during official long breaks. Final-year undergraduates who have completed 90% or more of the required credits can apply for individual permission to exceed this limit. The cap is cumulative across all paid activity combined, not per employer.
See our part-time jobs in Japan guide for the full breakdown.
Counselor insight: A common mistake is treating a paid research assistantship and a part-time café job as separate 28-hour allowances. They aren't; immigration counts all paid activity together against the same weekly cap.
Which Situation Are You In While Applying to Internships in Japan?
3rd-year engineering/science undergrad, no prior research experience: OIST is your strongest start: no nationality restriction, no English test, and broad eligible fields.
Specifically interested in particle physics or accelerator science: KEK is worth the odds, but apply to OIST or RIKEN in parallel, given that there are only 20-25 global seats.
PhD student or about to complete one: JSPS's Postdoctoral Fellowship is genuinely open to you, unlike its Summer Program. Also check whether your university could pursue a joint agreement with RIKEN for the IPA route.
Documents Required for Internships in Japan for Indian Students
| Document | India-Specific Detail |
|---|---|
| CV/Resume | English language; OIST requests a specific format; others accept your own |
| Statement of Purpose or Personal Statement | Typically 400 words for OIST; check exact word limits per program |
| Academic transcript | Official, in English or with certified translation |
| Letter of recommendation | At least one academic referee; KEK and OIST both require this |
| Home institution approval | Required for currently enrolled students applying to OIST and several RIKEN tracks |
| Passport | Valid well beyond your internship end date; required before visa/CoE processing begins |
Planning Calendar for Indian Students Applying to Internships in Japan (2027 Cycle)
| When | Indian Academic Context | What to Do |
|---|---|---|
| September-October 2026 | Odd semester underway | Shortlist OIST host units, KEK research groups, and RIKEN centre-specific programs; request recommendation letters early |
| Mid-October 2026 | Odd semester underway | OIST Spring 2027 cycle deadline (tentative; confirm exact date on oist.jp) |
| November-December 2026 | Odd semester exams | Prepare KEK application materials; KEK deadlines have historically fallen late Feb to early March |
| February-March 2027 | Even semester underway | KEK Summer Student Program deadline (confirm exact date on kek.jp/en); RIKEN CBS and IMS applications typically open in this window |
| April 2027 | Even semester underway | OIST Fall 2027 cycle deadline (tentative) |
| June-August 2027 | Summer break | Most Japan internship placements run during this window |
What to Do When Your Japan Internship Plan Hits a Problem
Your OIST application was rejected due to a host-unit mismatch: OIST weighs available space and funding per unit, not just merit. Reapplying with a revised host preference is legitimate, not a sign to give up.
No RIKEN centre has a formal listing in your field: Use direct professor outreach; many labs accept interns without a public posting if you ask directly.
JSPS's Summer Program rejected you: Expected if Indian without a completed or near-complete PhD; it's a nationality restriction, not a reflection on your application. Redirect toward OIST, RIKEN, or KEK.
Your paid company offer doesn't specify which visa applies: Ask the company directly before accepting. The distinction between Temporary Visitor, Cultural Activities, and Designated Activities depends on payment and duration, and getting this wrong risks a visa refusal or unlawful work violation.
How a Japan Internship Feeds Into Your Longer-Term Plans
A research internship is rarely the endpoint. For most Indian students, it's the first step toward a Japanese degree, a MEXT scholarship, or eventually a work visa.
| Next Stage | Eligibility / Requirement | Value to You | Source |
|---|---|---|---|
| OIST PhD Program (if internship was 4+ months) | Completing a 4-6 month OIST internship may satisfy one required lab rotation | Fast-tracks part of OIST's PhD program structure | OIST Research Internship Program Description |
| MEXT Scholarship (Master's/PhD) | Strong research profile; often needs a preliminary acceptance from a Japanese professor | Covers full tuition, JPY 117,000-145,000/month stipend (Rs.70,750-87,682), and airfare | Embassy of Japan in India |
| JSPS Postdoctoral Fellowship | PhD in hand or within 2 years of completion | 12-24 months of funded research, open to all nationalities including India | JSPS Postdoctoral Fellowships: Official Program Page |
| Specialist in Humanities/International Services or Engineer visa | Job offer from a Japanese employer post-graduation | Standard route into full-time work in Japan after study | Immigration Services Agency, Japan (J-Skip) |
| J-Find visa | Graduate of a top-ranked global university (within the last 5 years) | Longer job-hunting window than the standard post-graduation route | Immigration Services Agency, Japan (J-Find) |
OIST considers a 4+ month internship as potentially satisfying one lab rotation if you later join their PhD program, and a professor reference from your internship is particularly valuable in a MEXT application.
Counselor insight: The highest-leverage move after a research internship is asking your supervising professor directly whether they'd support a MEXT nomination or PhD application. Many Indian students complete a strong internship, then restart their Japan search from scratch instead of building on that relationship.
3 Takeaways for Internships in Japan
- OIST is the most accessible funded research internship in Japan for Indian students, with no nationality restriction and no English test; start there if unsure which program fits.
- JSPS's Summer Program isn't open to Indian nationals; only pursue JSPS via their Postdoctoral Fellowship at the PhD-completion stage.
- Company internships use a different visa framework than research institutes; confirm whether your offer needs a Designated Activities, Cultural Activities, or Temporary Visitor visa before accepting.

Frequently Asked Questions About Internships in Japan for Indian Students
-
Can Indian students get internships in Japan?
Yes, through named research programs like OIST, RIKEN, and KEK, none of which restrict India by nationality, plus professor outreach and company internships under Japan's standard visa framework.
-
Is JSPS open to Indian students for internships in Japan?
Not for their Summer Program, restricted to UK, French, German, Canadian, Swedish, and US citizens. Their Postdoctoral Fellowship is open to all nationalities, including Indian, but only for researchers with a PhD or within two years of completing one.
-
What is the OIST stipend, and how far does it go?
The stipend is JPY 2,400 per day (Rs. 1,451), non-taxable, and it is in addition to fully covered airfare, accommodation, and commuting. Since housing is covered, budget separately for food and personal spending, roughly Rs. 75,000-1.5L/month depending on the city if you are arranging anything independently.
-
How competitive is the KEK Summer Student Program?
Very. Only 20-25 students are selected globally each year, regardless of nationality. Apply to OIST or RIKEN in parallel rather than relying on KEK alone.
-
What visa do I need for a paid internship in Japan?
A curriculum-linked paid internship needs a Designated Activities visa, capped at one year and half your program length. If already on a Student visa, you need Permission to Engage in Activity Other Than That Permitted instead, subject to the 28-hour weekly cap.
-
Can PhD students apply for OIST or KEK internships?
No. Both exclude current or graduated PhD students; OIST's internship targets those considering a future PhD. PhD-level researchers should look at RIKEN's IPA program or JSPS's Postdoctoral Fellowship instead.
-
Do I need Japanese, and what if RIKEN has no listing in my field?
No Japanese is required; OIST, RIKEN, and KEK all operate in English. If no RIKEN centre has a formal listing in your field, direct outreach to a specific lab or PI is a legitimate, commonly used route, since RIKEN has no central internship portal.
