IMS Group

IMS Group, also known as the Itabashi Medical System Group, is one of Japan's largest comprehensive healthcare provider networks. Founded in 1956, the group operates an extensive infrastructure of over 140 facilities, including general hospitals, specialized clinics, rehabilitation centers, and nursing care facilities across the Kanto and Tohoku regions. The organization provides a full spectrum of medical services ranging from acute emergency care and advanced surgical interventions to preventive medicine and long-term elderly care. While primarily a service provider rather than a drug developer, IMS Group plays a critical role in the Japanese healthcare ecosystem through its large-scale clinical operations and medical education initiatives.
