Located conveniently in Atsubetsu Ward, Sapporo, directly connected to Exit 5 of Ōyachi Subway Station, Natsuizaka Internal Medicine Clinic has been serving the local community since its opening in 1985. The clinic is staffed by two physicians who hold multiple certifications including Board-Certified General Internist, Pulmonologist, Gastroenterologist, Hepatologist, and Board-Certified Gastroenterological Endoscopist, providing comprehensive care for a wide range of conditions from lifestyle-related diseases such as hypertension, diabetes, and dyslipidemia to respiratory, digestive, and cardiovascular disorders. A distinctive feature of the clinic is its advanced diagnostic equipment, including a 64-slice CT scanner (GE Revolution Maxima), the latest EVIS X1 gastrointestinal endoscopy system, and a high-performance Versana Premier ultrasound system—equipment comparable to that found in large hospitals. The clinic places particular emphasis on early cancer detection and prevention, offering precise diagnostics through a combination of gastroscopy, colonoscopy, and CT scans. Additionally, it is equipped with an exhaled nitric oxide analyzer useful for asthma diagnosis and a rapid infectious disease diagnostic system for early detection of conditions such as influenza. The clinic offers services in English, provides online consultations, issues prescriptions for 28 days or longer, and supports refillable prescriptions. Ample parking is available, making access by car convenient.
