Osono Internal Medicine Clinic, located in Tosu City, Saga Prefecture, is an internal medicine clinic operated by the medical corporation Taikeikai. Alongside its core internal medicine practice, the clinic offers a broad range of specialties including gastroenterology, gastrointestinal medicine, endoscopic medicine, and rehabilitation, and is recognized as a central family practice serving patients not only from the Tosu area but also from a wide region encompassing Ogori City, Kiyama, Miyaki, and Kurume City. A defining feature of the clinic is its gastrointestinal endoscopy services performed by Deputy Director Dr. Taiki Osono, who holds certifications as a specialist endoscopist from the Japan Gastroenterological Endoscopy Society, a specialist from the Japanese Society of Gastroenterology, and a specialist from the Japan Society of Hepatology. Upper and lower gastrointestinal endoscopy using high-resolution Fujifilm endoscopy systems and image-enhanced endoscopy is conducted every Friday and on the first, second, and fourth Saturdays, with same-day colorectal polyp removal also available. The use of sedatives to minimize discomfort during examinations is another aspect that has earned high praise. The clinic also places emphasis on managing lifestyle-related diseases and chronic conditions, and has implemented infection control measures including an online eligibility verification system, ozone generators, and UV sterilization equipment. Convenience is well addressed with English-language support, credit card and electronic payment options, parking, and barrier-free facilities. The ability to provide seamlessly integrated medical and nursing care through collaboration with the adjacent nursing care facility "Iyashi" stands as one of the clinic's key strengths.
