Regulatory Guidelines For Medical Device Registration In Japan: What You Need To Know

Japan is one of the world’s most sophisticated and tightly regulated medical device markets. Governed by the Pharmaceuticals and Medical Devices Agency and the Ministry of Health, Labour and Welfare, the regulatory framework ensures that all medical devices meet stringent standards for safety, quality, and clinical effectiveness.

With increasing emphasis on digital health, SaMD, and global harmonization, manufacturers entering Japan must navigate a structured yet complex approval process.

For global companies, compliance is not just mandatory, it’s a gateway to one of the most valuable healthcare markets worldwide.

What are Japan’s medical device registration requirements?
Japan requires medical devices to be classified by risk (Class I–IV), registered through a local Marketing Authorization Holder (MAH/DMAH), supported by Foreign Manufacturer Accreditation (FMA), and submitted with a STED dossier to the Pharmaceuticals and Medical Devices Agency (PMDA) for approval or certification.

Key Regulatory Framework

1. Product Classification (Risk-Based System)

Medical devices in Japan are categorized into four classes based on risk:

Why it matters:
Classification directly determines the approval route, documentation depth, and review timeline.

2. Marketing Authorization Holder (MAH/DMAH)

A Japan-based entity must hold the product license.

• MAH (Marketing Authorization Holder): Local legal manufacturer or subsidiary 
• DMAH (Designated MAH): Appointed representative for foreign manufacturers 

Responsibilities include:

• Regulatory submissions 
• Product release oversight 
• Post-market compliance 

Without a MAH/DMAH, market entry is not possible.

3. Foreign Manufacturer Accreditation (FMA)

All overseas manufacturing facilities must obtain FMA approval from the Ministry of Health, Labour and Welfare.

FMA Covers:

• Manufacturing site inspection readiness 
• Compliance with Japan’s QMS Ordinance 
• Alignment with ISO 13485 principles 

Think of FMA as a prerequisite license for manufacturing sites.

4. Application Dossier (STED Format)

Japan follows the Summary Technical Documentation (STED) format aligned with global standards.

Core Components:

• Device description & specifications 
• Intended use & indications 
• Risk management (ISO 14971 aligned) 
• Clinical evaluation data 
• Performance testing results 
• Quality Management System (QMS) evidence 

The dossier must demonstrate safety, performance, and benefit-risk balance.

5. Electronic Submissions & Language Requirements

Japan is actively transitioning toward digital regulatory systems, aligned with global frameworks like eCTD.

Key Points:

• Electronic submissions are increasingly required 
• Core documents may be in English 
• Critical sections must be translated into Japanese 

Poor translation quality is a common cause of delays.

6. Review Pathways in Japan

PMDA Review Includes:

• Technical dossier evaluation 
• Clinical data assessment 
• QMS inspection (onsite/remote) 

High-risk devices undergo rigorous scientific and regulatory review.

7. Quality Management System (QMS) Compliance

Japan enforces its own QMS Ordinance, aligned but not identical to ISO 13485.

Key Requirements:

• Design controls 
• Supplier management 
• CAPA (Corrective & Preventive Actions) 
• Risk management integration 

QMS compliance is verified during:

• FMA approval 
• PMDA inspections 
• Periodic audits 

8. Post-Market Surveillance (PMS)

Approval is just the beginning of ongoing compliance is critical.

MAH/DMAH Responsibilities:

• Adverse event reporting 
• Periodic safety update reports (PSURs) 
• Recalls and field safety corrective actions (FSCA) 
• Re-examination and re-evaluation processes 

non-compliance can lead to product suspension or revocation.

Recent Regulatory Updates (2024–2025)

1. Digital Transformation Initiatives

• Expansion of electronic submission frameworks 
• Integration with structured data systems (e.g., eCTD-like models) 

2. SaMD & AI Regulation Expansion

• Increased scrutiny for Software as a Medical Device (SaMD)
• AI/ML-based products now require robust validation and transparency 

3. Accelerated Approval Pathways

• Fast-track programs for: 
  • Breakthrough devices 
  • Orphan medical technologies 

4. Unique Device Identification (UDI)

• Mandatory UDI implementation for traceability 
• Alignment with global identification systems 

5. Bilingual Labeling Requirements

• Japanese labeling mandatory 
• English allowed as supplementary

Action Steps for Successful Registration

To ensure a smooth approval process:

• Conduct device classification assessment 
• Appointing a qualified MAH/DMAH partner 
• Secure Foreign Manufacturer Accreditation (FMA) 
• Prepare a complete STED dossier 
• Align QMS with Japan’s requirements 
• Plan for translation and localization 
• Develop a post-market surveillance strategy 

Quick Facts 

• Japan uses a 4-class risk-based system 
• MAH/DMAH is mandatory for market entry 
• FMA required for all foreign manufacturers 
• STED dossier aligns with global standards 
• PMDA conducts rigorous scientific reviews 
• Strong focus on post-market surveillance 

 Why This Matters

Japan’s regulatory system reflects a high-trust, high-compliance environment where technical precision and regulatory discipline are critical.

Under the oversight of the Pharmaceuticals and Medical Devices Agency, companies must demonstrate:

• Scientific rigor 
• Regulatory expertise 
• Quality system maturity 

Organizations that invest early in compliance frameworks gain:

• Faster approvals
• Stronger regulatory credibility
• Sustainable market access
