MAPI's next-generation medical database is a powerful foundation for accelerating medical AI research and development in Japan.
Here we describe its key features, the data it contains, the benefits of using it, the application process,
and our commitment to security and ethics.
MAPI's database integrates high-quality clinical information (electronic medical records, laboratory results, etc.) and medical imaging data (CT, MRI, etc.) collected from partner medical institutions across Japan, properly anonymized under the Next-Generation Medical Infrastructure Act. Its scale, the variety of its data, its quality management, and its rigorous security measures set it apart. We provide an environment where researchers can access valuable data with confidence.
The database contains diverse data items to meet research needs: diagnoses, prescription and injection histories, laboratory results, surgical records, medical images (CT, MRI, X-ray, pathology, etc.), and genomic information (in part). Please contact us for specifics such as the time span, cohort size, and main data items of each dataset. We aim to provide the data best suited to your research theme.

Using the MAPI database offers many benefits: dramatically shorter research timelines, lower R&D costs, large-scale data analysis beyond the reach of any single institution, new discoveries, and more accurate AI models. It powerfully supports innovation—from drug development to new diagnostics and treatments and personalized medicine. Selected use cases are also available.
Researchers at institutions and companies wishing to use the MAPI database can do so through a defined procedure. We will guide you through the application process, ethics review requirements, contract terms, and fees. Our support structure is designed to get you started smoothly and keep your research moving. Please feel free to contact us.
MAPI operates the database in compliance with the Act on the Protection of Personal Information and the Next-Generation Medical Infrastructure Act, under the highest standards of security and ethical consideration. Through thorough anonymization, prevention of unauthorized access, safeguards against data leakage, and strict access-log management, we are fully committed to protecting the valuable information entrusted to us and ensuring a safe environment for data utilization.
