Located in Otowa, Bunkyo Ward, Tokyo, Otowa Naika & Neurosurgery Clinic is a community-based clinic centered on internal medicine. In addition to weekday morning and afternoon sessions, the clinic is also open on Saturdays, making it accessible for patients balancing work and daily commitments. Since October 2025, the director has taken charge of all consultation days, including Tuesdays, ensuring continuous care under a consistent treatment policy. The clinic places particular emphasis on managing lifestyle-related diseases such as diabetes, hypertension, and dyslipidemia, regularly providing individualized treatment plans to each patient as part of its commitment to transparent, visible care. The clinic has also concluded a medical measures agreement with the Tokyo Metropolitan Government for febrile patients, enabling it to accept both initial and follow-up consultations when infectious disease is suspected. Active adoption of healthcare digital transformation — including electronic medical records, electronic prescriptions, online consultations, and My Number health insurance cards — is another distinguishing feature. Payment options include a wide range of cashless methods such as credit cards, transit IC cards, and electronic money, and the facility is fully barrier-free.
