Connected to the mainland by the Tsunoshima Bridge, the clinic serves as a vital hub for remote island healthcare, addressing a wide range of symptoms primarily through internal medicine. Consultation hours include a morning session from 9:00 AM to 12:00 PM as well as select afternoon periods, ensuring continued medical access for island residents.
