Mawatari Clinic, located in Arita-cho, Nishimatsuura-gun, Saga Prefecture, is an internal medicine practice. The clinic is distinguished by its focus on the early detection and treatment of gastrointestinal diseases. In addition to upper and lower gastrointestinal endoscopy, the clinic has introduced CT colonography, a procedure that allows visualization of the colon without inserting a camera, which is well regarded for its reduced burden on patients compared to conventional endoscopy or barium examinations. Endoscopic procedures are also available with intravenous sedation to minimize discomfort, and transnasal endoscopy is offered as an option. For general medical care, the clinic places emphasis on managing chronic conditions such as hypertension, diabetes, and hyperlipidemia, as well as treating lifestyle-related diseases, and also handles infectious diseases including COVID-19 and influenza. A wide range of health checkup and cancer screening programs are available, including a comprehensive full-body examination course priced at 77,000 yen (tax included), which covers chest and abdominal CT scans, upper endoscopy, and colorectal examination. English-speaking support is available, and the clinic accepts credit cards and electronic payments. Parking and barrier-free facilities are also provided, making the clinic accessible to a broad range of patients.
