Hiro Internal Medicine Clinic, located in the Asama Onsen area of Matsumoto City, Nagano Prefecture, is a medical facility specializing in internal medicine. A distinctive feature of this clinic is its dedicated sleep medicine outpatient clinic, with appointment-based sleep consultations available on Monday, Tuesday, Wednesday, and Friday afternoons as well as Saturdays. For sleep disorder consultations, patients are encouraged to keep a "sleep diary" for at least two weeks prior to their visit, reflecting the clinic's thorough approach to understanding daily sleep patterns before initiating treatment. Morning hours begin at 8:45 AM, and afternoon consultations run from 3:00 PM to 6:00 PM. The clinic is closed on Thursdays, Sundays, national holidays, as well as during the year-end/New Year and Obon periods. An on-site parking lot ensures easy access by car, and the acceptance of credit cards and electronic payments adds to overall convenience. With its combination of general internal medicine and a highly specialized sleep clinic, Hiro Internal Medicine Clinic serves as a healthcare facility that addresses a broad range of health needs in the local community.
