Case Study: Research Doesn’t Stop, Even Without a Legal Entity – Building an Immediate-Impact Team in Japan Through Flexible Engagement
For early-stage biotech companies entering Japan, access to specialised talent is often required before permanent hiring becomes viable.
In this case, Greenstaff Life Sciences supported a biotech client in launching research activities in Japan through temporary staffing and contract-based engagement – enabling speed, compliance, and flexibility without delaying critical timelines.
The Challenge
- No Japanese legal entity, making permanent hiring impractical
- Immediate need for specialised talent across drug discovery, TR, and CMC
- Tight research timelines with limited hiring flexibility
- Limited familiarity with Japanese labour and contract frameworks
Our Approach
- Designed a phased structure using temporary staffing and contract-based engagement
- Rapidly deployed specialist talent across core research functions
- Defined clear scopes aligned with research deliverables
- Ensured compliance with Japanese labour and contract requirements
- Preserved flexibility for future transition to permanent hiring
The Results
- Research activities launched on schedule without a local entity
- Specialist professionals deployed within weeks
- Critical research capability secured with controlled cost and risk
- Clear pathway established for team expansion
Key Takeaway
Immediate talent needs do not always require permanent employment.
When applied strategically, temporary staffing (haken) and contract-based engagement enable speed, expertise, and flexibility – while keeping long-term options open.
