Medical Corporation Koike Clinic, located in Fujimi-machi, Suwa-gun, Nagano Prefecture, is an internal medicine clinic situated in a nature-rich environment with views of the Yatsugatake Mountains, Mt. Fuji, and the Southern Alps. The clinic's history dates back to 1935, when the first director established the practice in Fujimi-machi. Since then, it has served as a family doctor for local residents across generations. The five pine trees standing in the front garden since the clinic's founding continue to welcome visitors, bearing witness to this long history. Currently, the clinic operates with a two-physician system led by Director Hajime Koike and Vice-Director Tomohiro Koike, and its family-oriented approach to community healthcare is a distinctive feature. The clinic focuses on treating lifestyle-related diseases such as hypertension, diabetes, and hyperlipidemia, while also providing vaccinations and health examinations, covering a wide range of services from daily health management to ongoing care for chronic conditions. The facility includes parking and is barrier-free, creating an accessible environment for those traveling by car or requiring physical assistance. The clinic is closed on Sundays, public holidays, during the New Year period, and during the Obon season.
