What is PMDA?

The Pharmaceuticals and Medical Devices Agency (PMDA) is an independent administrative agency in Japan that reviews and approves pharmaceuticals, medical devices, and regenerative medical products. PMDA also conducts post-marketing safety measures and provides relief services for health damages.

PMDA works closely with the Ministry of Health, Labour and Welfare (MHLW), which grants final approval based on PMDA review. The regulatory system includes Shonin (approval) for new drugs and medical devices.

Japan participates in ICH and has harmonized many requirements with global standards, though some Japan-specific requirements remain, including Japanese bridging studies in some cases.
