Located along National Route 5 in Otaru City, Hokkaido, Kitaoka Internal Medicine and Gastroenterology Clinic is a medical clinic specializing in internal medicine and gastroenterology. Physicians certified by the Japan Gastroenterological Endoscopy Society provide consultations, addressing a wide range of conditions from lifestyle diseases such as diabetes and hypertension to gastrointestinal disorders including abdominal pain, diarrhea, and heartburn. The clinic places particular emphasis on endoscopic examinations, creating a minimally uncomfortable environment through appropriate sedation (light general anesthesia) and the use of slim and transnasal endoscopes. The facility features Fujifilm's latest laser endoscopy system, making it the third institution in Otaru City to adopt this technology. By combining laser light with magnified imaging, the system enables more precise assessment of colonic polyp characteristics. Additionally, the clinic provides two private rooms equipped with dedicated restrooms and reclining chairs for patients taking laxatives before colonoscopy, allowing for examination preparation in a privacy-conscious environment. Upper gastrointestinal endoscopy is available on the same day, and the clinic also offers Helicobacter pylori testing and treatment as well as same-day polypectomy. English-speaking support is available, and the facility offers 18 free parking spaces and barrier-free access.
