Minami-Osawa Clinic, located in Minami-Osawa, Hachioji City, Tokyo, is a medical facility specializing in internal medicine and gastroenterology. As a community-based primary care physician, the clinic provides comprehensive internal medicine services, including treatment for lifestyle-related diseases and metabolic syndrome such as hypertension, diabetes, hyperlipidemia, and hyperuricemia. The clinic places particular emphasis on the diagnosis and treatment of gastrointestinal disorders, addressing a wide range of conditions affecting the esophagus, stomach, duodenum, large intestine, liver, biliary tract, and pancreas. For examinations, the clinic has introduced transnasal endoscopy, which is inserted through the nose rather than the mouth, allowing patients who feel uncomfortable with conventional gastroscopy to undergo the procedure with relatively less burden. Colonoscopy examinations are also available, enabling comprehensive gastrointestinal examinations to be completed at a single facility. Additionally, the clinic provides home healthcare services (house calls), making it a reliable option for patients who have difficulty visiting the clinic. Operating hours are divided into morning (9:30-12:00) and afternoon (15:00-19:00) sessions, with a dedicated fever outpatient service also available. The clinic is equipped with parking facilities, accommodating access by car.
