Japan is one of the most attractive and lucrative pharmaceutical markets in the world—but it is also one of the most tightly regulated. For foreign manufacturers, one regulatory requirement stands above all others: local agent representation. Without it, product registration in Japan is simply not possible.

The MAH/DMAH Requirement Explained

In Japan, medicinal products cannot be registered, imported, or sold unless a locally established entity holds regulatory responsibility. This role is fulfilled by either a Marketing Authorization Holder (MAH) or a Designated Marketing Authorization Holder (DMAH).

The MAH/DMAH is legally accountable for:

• Product quality, safety, and efficacy
• Post-marketing surveillance
• Regulatory compliance throughout the product lifecycle
• Communication with Japanese health authorities

Without this local presence, applications are automatically rejected—regardless of how strong the scientific data may be.

Why Foreign Manufacturers Face Rejections

Many global companies underestimate the complexity of Japan’s regulatory framework. Common pitfalls include:

• No legally established MAH/DMAH in Japan
• Incomplete or non-localized dossiers
• Misalignment with Japanese guidelines and expectations
• Communication gaps with authorities like the Pharmaceuticals and Medical Devices Agency (PMDA)

These issues often result in costly delays, multiple review cycles, or outright rejections.
