Osada Naika Clinic is an internal medicine specialty clinic located in Yamamiyacho, Kofu City, Yamanashi Prefecture. In June 2025, due to prefectural road widening construction, the clinic relocated approximately a 2-minute walk south from its former facility, continuing regional healthcare services in its new medical environment. Post-relocation consultation hours are 9:00 AM to 12:15 PM (Monday through Saturday), with afternoon sessions from 3:00 PM to 5:45 PM (Monday and Friday only). The clinic is closed on Sundays, national holidays, and the fifth Wednesday of each month. Covering general internal medicine, the clinic addresses a wide range of conditions from acute illnesses such as fever, colds, and gastrointestinal symptoms to ongoing management of lifestyle-related diseases including hypertension, diabetes, and dyslipidemia. The clinic features a parking lot, providing easy access by car. Additionally, barrier-free facilities are in place, creating an environment where elderly patients and those with physical disabilities can receive care with peace of mind. Continuing its community-rooted attentive medical care after relocation, the clinic has earned trust as a reliable primary care provider in the northern Kofu City area.
