AboutAbout the lab
Evidence for better health policy tomorrow
The lab conducts research to improve future healthcare and long-term care policy.
It aims to produce the evidence that underpins policymaking and to engage with society, as well as to train the people who will support future health policy.
Its work includes evaluating policies using administrative data such as insurance claims, and studying healthcare and long-term care delivery systems, cancer control, and health technology assessment.
Key terms
- Receipts (insurance claims)
- An itemized statement that medical institutions and pharmacies submit to insurers to claim payment for the care they provided and its cost
- Econometric methods
- Statistical methods developed in economics. They isolate from data, and measure, the effects that changes such as institutional reforms have had on people
- Health technology assessment (HTA)
- Evaluating new drugs, treatments, and other technologies in terms of their effectiveness, cost, and social impact

ResearchResearch themes
The lab aims to produce evidence for better health policy tomorrow and to engage with society. It studies healthcare and long-term care delivery systems, policy evaluation using administrative data, cancer control, innovation for healthy living, and health technology assessment.
*Illustrative imageHealthcare and long-term care delivery systems
This research looks ahead to a society with a growing number of older adults who need both medical and long-term care and a shrinking working-age population to support them. The lab broadly examines healthcare and long-term care policies in Japan and abroad, including their background and how policies are decided.
*Illustrative imageEvaluating policy with administrative data
The lab examines how institutional reforms, such as revisions to medical fee schedules and changes in patient copayment rates, have affected the quality of healthcare and long-term care and people's health. It applies econometric methods such as difference-in-differences and instrumental variables to administrative data such as insurance claims.
*Illustrative imageImproving the effectiveness of cancer screening
To make cancer screening programs run by municipalities more effective, the lab focuses on raising participation rates and improving screening quality. Through analysis of administrative data and interviews with municipalities, it examines measures that would make cancer screening more effective.
*Illustrative imageAdvanced technology to support independent living
This research uses advanced technologies such as AI, IoT, and robotics to build a society where people can live independently in the communities they are used to, regardless of age or physical and mental condition. The lab studies how to build systems that embed advanced technologies in society.
