Okoda Naika Clinic is an internal medicine clinic conveniently located right in front of the JR Kofu Station North Exit. One of the clinic's distinctive features is that the director, a board-certified specialist of the Japan Society of Hepatology, personally oversees the diagnosis and treatment of liver diseases. With 20 years of experience in gastroenterology at a university hospital, the director develops appropriate treatment plans tailored to each patient's condition and provides referrals to advanced medical institutions when necessary. For endoscopic examinations, a specialist certified by the Japan Gastroenterological Endoscopy Society provides care, employing transnasal endoscopy that prioritizes patient comfort, while also performing colonoscopies. Gastroscopies are available without prior appointment. The clinic treats a wide range of conditions, from general internal medicine issues such as colds and fevers to lifestyle-related diseases including hypertension and diabetes, as well as providing vaccinations, serving as a primary care physician for the local community. The facility is wheelchair accessible and offers free parking vouchers for affiliated parking lots, ensuring convenient access for patients visiting by car.
