Kumamoto Central Hospital, located in Taisima, Minami Ward, Kumamoto City, Kumamoto Prefecture, provides medical care specializing in internal medicine and diabetes/metabolic medicine. Reception hours on weekdays are from 8:00 to 11:00, and the hospital is closed on weekends, holidays, and during the year-end and New Year period (December 29 to January 3). First-time patients generally do not require appointments and can visit directly during outpatient reception hours. However, some departments such as Breast Surgery and Pediatric Endocrinology operate by appointment, so prior confirmation is recommended when visiting these departments. Patients are advised to bring a referral letter or detailed examination request form; without these, an additional fee of 7,700 yen (tax included) may apply as a non-covered medical expense for initial consultations. The hospital accepts credit cards, debit cards, and electronic payments, offering various payment options. English assistance is available, and the facility features parking and barrier-free access. With a system that provides specialized diabetes and metabolic care alongside general internal medicine, patients can expect smoother consultations by bringing a referral letter.
