Iwase Internal Medicine & Gastroenterology is a clinic specializing in internal medicine and gastroenterology, located in Shinae-cho, Naka-ku, Nagoya, Aichi Prefecture, and opened in May 2020. The director, Dr. Hiroaki Iwase, holds a doctorate in medicine and brings extensive experience as a specialist and supervising physician, having spent 25 years at Nagoya Medical Center in the diagnosis, treatment, and research of gastrointestinal diseases. The clinic leverages this expertise to provide gastroenterological care as its core service, while also offering prevention and treatment of lifestyle-related diseases such as hypertension, diabetes, hyperlipidemia, and hyperuricemia (gout), as well as general internal medicine for conditions including allergies, fever, cough, and runny nose. The gastroenterology department employs low-discomfort endoscopic examinations and abdominal ultrasound, using cameras to examine the esophagus, stomach, duodenum, and colon, and ultrasound for the diagnosis and treatment of the liver, pancreas, and biliary tract. Upper endoscopy is available for diagnosing cancer, polyps, Helicobacter pylori-related gastritis, gastric ulcers, and reflux esophagitis, while lower endoscopy enables detailed observation of the entire colon. English-language consultations are available. Office hours are 9:00–12:30 in the morning and 14:00–16:00 in the afternoon, with closures on Sundays, public holidays, year-end and New Year holidays, Golden Week, and Obon.
