Naito Internal Medicine & Diabetes Clinic is located in Happonmatsu-minami, Higashihiroshima City, Hiroshima Prefecture, and opened in 2025 as a clinic specializing in internal medicine and diabetology. Director Dr. Maiko Nomura holds certifications as a diabetes specialist and general internal medicine specialist, and upholds the philosophy of giving back to the local community with the knowledge and experience cultivated in her hometown of Happonmatsu. The clinic places particular emphasis on diabetes care, addressing this condition—which has been shown to be associated with increased risks of myocardial infarction, cerebral infarction, dementia, and cancer—by proposing treatment plans tailored to each patient's lifestyle. The clinic actively utilizes newly developed medications and considers the optimal approach from a wide range of treatment options. Beyond diabetes, the clinic also handles general internal medicine consultations, including abnormal values found in health checkups and concerning changes in physical condition, serving as a reliable primary care provider. Office hours are set for weekday mornings (excluding Thursday) and Saturday mornings, with reception on Saturdays until 12:30. The facility is barrier-free and accepts credit cards and electronic payments, making it accessible to a wide range of patients. English-language consultations are also available, ensuring that non-Japanese speakers can receive care with confidence.
