This study legally compared the personal information protection systems between Japan and South Korea that must be observed when providing Real-World Data obtained at medical institutions to third parties. It was clarified that Japan does not have a system to link pseudonymized data with each other, and Korea does not have a system for DB operators to collect medical data from medical institutions on a large scale. For both countries, understanding the operation of each other's systems will lead to improvements in their own systems.
