• A PhD or equivalent research experience in a relevant field of natural sciences or related areas.
• A strong research track record that demonstrates independence, originality, and the potential to lead a group.
• No formal age limit, and no strict cap on years since PhD; the emphasis is on being at an early career stage and having limited PI experience.
• Willingness to work full-time at a RIKEN campus in Japan; remote work from outside Japan is not permitted.

International Applicants

The RIKEN ECL Program is explicitly open to researchers from around the world, not only from Japan.

For international candidates (including those currently based in India, Europe, or North America), this means:

• • You can apply directly from your current institution.
  • If successful, relocation support and standard RIKEN benefits (such as commuting and housing allowances) are typically available under RIKEN regulations.

Support for Women Researchers: The Sechi Kato Program

Women scientists hired as ECL Team or Unit Leaders may receive additional research funding of up to 10 million JPY per year through the Sechi Kato Program, aimed at fostering women research leaders.

This integration of the Sechi Kato Program into the ECL framework is a major advantage for female applicants planning to build strong, well-funded labs in Japan.

Key Features, Salary, and Research Environment

Appointment Term and Work Conditions

• • Term of employment: up to seven years (with contracts structured as single-year or multi-year agreements).
  • Working hours: Standard daytime schedule with flexibility as long as research duties are met.
  • Leave and benefits: Annual paid leave, special leave (childcare, family care), and dedicated work–life balance leave are available, along with social insurance.

Salary and Allowances

• • ECL Team Leader: approximately 10.92 million JPY per year.
  • ECL Unit Leader: approximately 8.52 million JPY per year.
  • Commuting and housing allowances, social insurance, and membership in the RIKEN Mutual Benefit Society apply according to internal regulations.

Research Funding and Infrastructure

• • Team Leaders receive an average of 30 million JPY per year in research funding.
  • Unit Leaders receive an average of 10 million JPY per year in research funding.
  • Additional start-up funds help establish the lab quickly.
  • Leaders can use shared equipment and advanced core facilities across various RIKEN campuses.

This combination of stable salary, strong research budget, and infrastructure makes it possible to pursue high-risk, high-impact projects from day one.

Step-by-Step: How to Apply for the RIKEN Early Career Leaders Program

While specific procedures vary

by fiscal year, the application flow typically includes these stages. Always confirm details in the official call for applications on the RIKEN website 

1. 1. Check the Latest Call and Eligibility: First, read the Recruiting Policy and the current Call for ECL Team / Unit Leaders carefully. For example, the FY2025 call sets separate deadlines for pre-registration and document submission and explains how many positions may be filled.

1. 2. Pre-Registration: Most recent calls require online pre-registration by a specified deadline (for FY2025, early August Japan time. Prepare ahead:

• • • A concise research summary.
    • Basic personal and academic information.
    • Your preferred track (Team Leader or Unit Leader).

1. 3. Full Application Submission: After pre-registration, you will receive instructions to upload:

• • • A detailed research proposal (usually multi-year, including budget strategy).
    • CV and publication list highlighting key achievements and leadership potential.
    • Recommendation letters, often from international leaders in your field.
    • Any additional documents requested in the specific call (e.g., diversity statements).

For FY2025, the deadline for final document upload and recommendation letters falls around mid-August (Japan time).

1. 4. Screening and Interviews: The selection process typically involves:

• • • Document screening, focusing on originality, feasibility, and impact of the research plan.
    • Interviews or presentations, where candidates present their vision as independent PIs and answer questions from a selection committee.

Final offers are made after a comprehensive evaluation of scientific track record, leadership potential, and fit with RIKEN’s long-term strategy.

Tips, Common Mistakes, and Expert Advice

Practical Tips for a Strong Application

• • Align your proposal with RIKEN strengths
    Show how your group will complement or extend existing programs in areas such as life sciences, materials science, computational science, or interdisciplinary fields.
  • Demonstrate leadership, not just excellence
    The ECL Program is about building leaders. Therefore, highlight mentoring experience, cross-disciplinary collaborations, and previous initiative in starting new lines of research.
  • Build a realistic seven-year plan
    The selection committee expects a coherent timeline: early proof-of-concept work, group expansion, external funding strategy, and pathways to translation or societal impact.
  • Clarify your international profile
    For non-Japanese applicants, emphasise international collaborations, mobility, and your plans for integrating into Japanese research ecosystems.

Common Mistakes to Avoid

• • Generic research proposals
    Vague or overly broad projects that could be done anywhere tend to underperform. Instead, clearly explain why RIKEN and its facilities are essential to your plan.
  • Underestimating budget planning
    Some candidates propose ambitious experiments without matching resource and staffing plans. Therefore, link your budget and personnel requests to specific work packages.
  • Ignoring diversity and inclusion aspects
    RIKEN explicitly emphasises diversity and better representation of women in PI roles. If relevant, explain how your lab will build an inclusive research culture.
