JSPS Invitational Fellowships for Research in Japan: A Practical Guide for Invitation-Based Research Visits

Japan’s JSPS Invitational Fellowships for Research in Japan are a distinctive route for experienced overseas researchers who want focused collaboration with Japanese peers—without enrolling in a degree program. Unlike many fellowships where the applicant applies directly, a Japanese host researcher submits the application through their institution using JSPS’s electronic system.

In this guide, you will learn what the program supports, how Long-term [L] and Short-term [S] tracks differ, who is eligible, and how to plan an application that reviewers can score highly. The goal is simple: help you convert a promising Japan collaboration into a complete, compliant proposal that a host institution can submit confidently.

Overview: what the JSPS Invitational Fellowships are

The Japan Society for the Promotion of Science (JSPS) runs these fellowships to bring excellent overseas researchers to Japan for collaborative research, discussions, and exchange of perspectives with researchers in Japan.

Two categories matter for most candidates:

• • Invitational Fellowship (Long-term) [L]: collaborative research through longer visits.

  • Invitational Fellowship (Short-term) [S]: short visits for discussions, opinion exchange, lectures, and related activities.

Importantly, the program covers all fields, including humanities, social sciences, and natural sciences.

Why this program matters for international researchers

This is not a generic visiting position. Instead, JSPS Invitational Fellowships work best when you already have a clear match with a Japanese lab, center, or department.

Key benefits include:

• • High-signal affiliation: A JSPS-backed visit can strengthen credibility for future joint grants and publications.

  • Fast collaboration cycles: Short-term visits support workshops, invited lectures, and project kickoffs that can mature into longer research outputs.

  • Defined support structure: JSPS specifies the support items and expects a concrete plan, which keeps the visit outcome-focused.

Moreover, the host-led format can reduce uncertainty because the Japanese institution anchors timelines, internal approvals, and compliance steps.

Long-term [L]: when you need sustained collaboration

Long-term [L] supports 2 to 10 months in Japan, counted in full-month units, and JSPS does not allow tenure extensions. This track fits goals such as building datasets together, running experiments that need lab access, or writing a multi-institution manuscript.

Short-term [S]: when outcomes are meetings, lectures, and rapid planning

Short-term [S] supports 14 to 60 days, and it also prohibits tenure extensions. Use it for seminars, invited lectures, planning sessions, and early-stage collaboration where a short, intensive visit creates momentum.

A simple decision rule

If your deliverables require continuous lab or archive time, start with [L]. However, if your deliverables are workshops, lecture series, and project design, [S] is usually the better fit.

Eligibility: who can be invited and who can host

Candidate (invited overseas researcher) eligibility

JSPS expects the invited researcher to be a citizen or permanent resident of a country with diplomatic relations with Japan (with specific treatment noted for Taiwan and Palestine).

In addition, candidates should hold full-time researcher status at a foreign university or research institution, typically at a senior rank comparable to professor/associate professor/assistant professor (including emeritus). Alternatively, researchers of other status may qualify if it has been six years or more since the doctoral degree, and the host institution judges they have continuously conducted research abroad.

JSPS also describes a pathway for Japanese nationals who have lived abroad for 10 years or longer and played an active role in the host country’s scientific community.

Host researcher and host institution eligibility

The applicant is the Japanese host researcher, not the overseas candidate. Applications must go through the host institution and the JSPS electronic system. JSPS does not accept individual submissions from candidates.

Hosts must be affiliated with eligible research institutions and be able to apply for KAKENHI, with the intent to host an overseas researcher. They should also be full-time researchers, although certain non-full-time cases may qualify if the institution confirms the host can execute responsibilities throughout the fellow’s tenure.

Funding and support: what JSPS typically covers

JSPS defines the main support items and notes they may change due to budget conditions.

Financial support for Long-term [L]

Support typically includes:

• • Roundtrip airfare (economy-class) based on JSPS regulations

  • Maintenance allowance: JPY 387,600 per month

  • Overseas travel insurance

  • Research support allowance: up to JPY 150,000 (applied for by the host through their institution)

Financial support for Short-term [S]

Support typically includes:

• • Roundtrip airfare (economy-class)

  • Maintenance allowance: JPY 18,000 per day

  • Overseas travel insurance

  • Research support allowance: up to JPY 150,000 (host-applied)

Also note: if a fellow is already in Japan before the fellowship starts, JSPS may not pay airfare for the flight to Japan.

Step-by-step: how to apply for the JSPS Invitational Fellowship

Step 1: build a host agreement and a review-ready plan

First, align on a defined research theme, visit dates, and expected outputs. Reviewers expect clear evidence that the host and candidate established contact and planned activities in advance.

Step 2: confirm deadlines early (internal deadlines may be earlier)

JSPS sets the deadline for institutions. However, host universities often impose an earlier internal deadline, sometimes more than a month before the JSPS cutoff. Therefore, ask the host’s research administration office for the internal deadline before drafting.

For FY2026, JSPS lists (among other rounds) a Short-term (2nd) deadline of August 28, 2026 (5 p.m. JST).

Step 3: prepare the correct forms with your host

For Long-term [L], the forms include:

• • L-1 (entered in the electronic system by the host)

  • L-2 (research proposal document prepared jointly)

  • L-3 (candidate CV)

For Short-term [S], the equivalents are:

• • S-1 (entered by the host)

  • S-2 (research proposal document prepared jointly)

  • S-3 (candidate CV)

Step 4: host submits via the JSPS Electronic Application System

Your host completes the online entry, uploads the proposal and CV files, and submits to the host institution. Then the institution transmits the final application to JSPS.

Step 5: understand selection and plan logistics early

JSPS selection typically includes a document review and a panel review. In addition, JSPS defines the fellowship period in relation to arrival and departure at Japanese airports, which affects travel planning and budgeting.

Tips, common mistakes, and expert advice

What strong applications do consistently

• • Make the “why Japan, why now” argument explicit. Link facilities, datasets, archives, or scholarly communities to your plan.

  • Define outputs that match the tenure. For [S], aim for workshops, lectures, joint outlines, or pilot results. For [L], plan for publishable results and measurable milestones.

  • Show capacity on both sides. Explain what the host provides and what the invited researcher contributes.

Common mistakes that weaken otherwise good profiles

• • Treating it like a personal grant. The host institution owns submission and compliance steps, so plan around their workflows.

  • Overpromising deliverables. Short visits cannot credibly deliver multi-year outcomes. Instead, propose staged outputs.

  • Using copied text. JSPS warns that falsified or plagiarized content can lead to rejection or withdrawal. Write everything fresh and specific to the project.

A practical candidate checklist before your host submits

• • Updated CV aligned to the visit’s theme, with selected publications and projects

  • One-page “visit outcome plan” listing deliverables and a realistic timeline

  • A short list of facilities, data, or collaborations you need from Japan

  • A risk note covering ethics approvals, data privacy, or sensitive technology topics

  • Clean writing with consistent terminology across the proposal and CV

Finally, JSPS cautions applicants about risks associated with generative tools, such as copyright issues and information leakage. Treat this as a reminder to keep your proposal original and to avoid sharing sensitive institutional data in public tools.

Conclusion

JSPS Invitational Fellowships for Research in Japan reward one thing above all: a well-matched partnership with a Japanese host and a credible plan that fits the visit length. Choose [S] when outcomes are discussion-led and fast-moving, and choose [L] when you need sustained collaboration to produce deeper research outputs. In either case, work backward from your host institution’s internal deadline and co-write the proposal so it reads like a joint project, not a solo visit.

For the most accurate schedules, forms, and submission rules, rely on the official JSPS program guideline page and your host institution’s research office. Prepare your documents early so your host can submit without last-minute risk.
