Sanbommatsu Clinic, located in Higashihanawa, Chuo City, Yamanashi Prefecture, is a community-based internal medicine clinic. Chuo City spreads across the southern Kofu Basin as a residential area, and the clinic serves as a healthcare pillar within this daily living environment. Specializing in internal medicine, the clinic handles a broad range of conditions, from acute illnesses such as colds and fevers to ongoing management of lifestyle-related diseases including hypertension, diabetes, and dyslipidemia. As a local primary care provider, the clinic continuously monitors each patient's condition and facilitates referrals to specialized medical institutions when necessary. The clinic offers parking facilities, enabling convenient car access—a practical advantage given the limited public transportation in Yamanashi Prefecture. Operating mainly on weekdays, the clinic is closed on Sundays, the second Saturday, and national holidays. It serves as an accessible healthcare gateway for local residents seeking care for health concerns or regular health management.
