Obayashi Clinic, located in Suzuki-cho, Kodaira City, Tokyo, is an internal medicine and pediatrics practice within walking distance of Hanakoganei Station on the Seibu Shinjuku Line. Director Dr. Yutaka Obayashi has established "patient-centered care" as his guiding principle, placing great importance on carefully listening to patients' symptoms and explaining treatment plans until patients are fully satisfied. The internal medicine department covers a broad spectrum of conditions including diabetes, cardiovascular diseases, gastrointestinal disorders, and rheumatism and collagen diseases, while general pediatric consultations are also available. On Wednesdays and Fridays, pediatric specialist Dr. Osada joins the director for full-day practice, enabling children to receive examinations under more specialized support. The clinic also offers a walk-in smoking cessation program and provides a wide range of health screenings, including general health checkups, specified health examinations, corporate health examinations, and school and employment entrance health checks, as well as both routine and voluntary vaccinations. The clinic participates in the publicly subsidized pneumococcal vaccination program, fulfilling its role as a community preventive care provider. A parking lot and barrier-free design ensure easy access for those arriving by car or with mobility limitations.
