Regulatory Affairs Service Provider in Japan
The Pharmaceuticals and Medical Devices Agency (PMDA) is the Japanese regulatory body that operates in collaboration with the Ministry of Health, Labour, and Welfare. The PMDA plays a central role in Japan’s regulatory affairs processes by protecting public health through the evaluation of product safety, effectiveness, and quality of pharmaceuticals and medical devices. It is responsible for developing detailed regulatory frameworks, conducting thorough assessments, and ensuring rigorous post-market safety surveillance .
Moreover, the PMDA also provides compensation to individuals who experience adverse drug reactions or biological product-related infections. This falls under a three-pillar system unique to Japan, which integrates:
- Medicinal product review
- Post-marketing safety measures
- Relief services for adverse health outcomes
Our comprehensive system provides PMDA regulatory affairs services. Recognizing the growing importance of international cooperation, the PMDA has actively formed partnerships with agencies across the EU, US, Asia, and other regions. These collaborations support key initiatives under the International Council for Harmonisation (ICH) and contribute to timely, transparent, and effective dissemination of drug safety information to the public. Such global alignment further strengthens Japan regulatory landscape at an international level.
