Nagomi Clinic, located in Shimo-Shakujii, Nerima Ward, Tokyo, is an internal medicine clinic conveniently situated just a 5-minute walk from Kami-Igusa Station on the Seibu Shinjuku Line. Director Masahisa Osada holds dual certifications as a General Internal Medicine Specialist and a Gastroenterology Specialist, making a broad, patient-centered perspective the cornerstone of his practice—even in an era of increasing medical specialization. The clinic covers a wide range of services, from general internal medicine to lifestyle-related conditions such as hypertension and diabetes, gastroenterology, and allergy care, as well as a smoking cessation program and private-pay treatments for ED and AGA. For endoscopic examinations, both transnasal and transoral approaches are available, allowing patients to choose the method that best suits their preferences and condition. In addition to state-of-the-art endoscopy equipment, the clinic is well equipped with ultrasonography, electrocardiography, and other diagnostic tools, enabling most tests to be completed on-site. Health checkups are available for individuals and corporate clients, and the clinic is a designated provider for specific health examinations in both Nerima and Suginami Wards. Vaccination services include seasonal influenza and pneumococcal vaccines, as well as self-pay travel vaccines for hepatitis A and B. With 10 patient parking spaces, 30 bicycle spaces, and full barrier-free accessibility, the clinic ensures a comfortable visit for wheelchair users and elderly patients alike. Striving to be a clinic where patients feel free to consult about even minor concerns, Nagomi Clinic supports community healthcare across all generations, from children to the elderly.
