Takamatsu Medical Clinic, located in Shimorenjaku, Mitaka City, Tokyo, is an internal medicine clinic that opened in November 2007 along Chuo-dori near the south exit of Mitaka Station. The clinic director studied infectious diseases, HIV/AIDS, and hepatitis C at Yamaguchi University and the graduate school of Tokyo Medical and Dental University, and subsequently spent many years engaged in the prevention and treatment of lifestyle-related diseases at a hospital in Mitaka City. Drawing on this extensive experience, the clinic emphasizes disease prevention, early detection, and early treatment. Covering general internal medicine, the clinic treats conditions such as influenza, Hashimoto's disease, and cough-variant asthma, and also offers various vaccinations and health checkups. A notable feature is that small dense LDL (sd-LDL) testing — considered a highly atherogenic marker — is available without an appointment. The clinic also participates in the Mitaka City Resident Health Examination program, playing a key role in supporting preventive healthcare in the community. Consultation hours are from 9:00 AM to 12:30 PM and from 2:00 PM to 6:00 PM, with closures on Sundays, national holidays, and approximately one week during the Obon period and the New Year holidays. The clinic accepts credit cards, debit cards, and electronic payments, and is equipped with barrier-free facilities, making it accessible to a wide range of patients.
