Horii Hospital Medical Corporation, located in Funakicho, Ibaraki City, Osaka Prefecture, is an internal medicine clinic specializing in gastroenterology. Since 2005, the hospital has introduced thin-diameter transnasal endoscopy, performing gastrointestinal examinations with minimal discomfort using gastric cameras inserted through the nose. Traditional oral gastric camera examinations are also available, and appointments for gastric cameras can be made by phone, at the counter, or online. The hospital also performs minimally painful colonoscopy examinations for early detection of colorectal cancer and polyps, which have been increasing due to recent changes in dietary habits. In addition to gastroenterology, the hospital provides treatment for lifestyle-related diseases such as diabetes and hypertension, as well as general internal medicine care. Consultations are generally on a first-come, first-served basis, with a numbered ticket system upon arrival. However, reservations are accepted only for gastric cameras and screenings. The hospital accepts credit cards and electronic payments, and has parking spaces. It is barrier-free and provides services in English. The director is a gastroenterologist who graduated from Hokkaido University School of Medicine and has 25 years of clinical experience. Patients are required to wear masks when visiting the hospital.
