Located just a 1-minute walk from the south exit of Oizumi Gakuen Station in Nerima Ward, Tokyo, Yasuhisa Naika Clinic is an internal medicine specialty clinic operated by Iryo Hojin Shosennkai. Housed on the first floor of the Sandlerion Building, the clinic features barrier-free architecture, ensuring a comfortable environment for wheelchair users and those with mobility concerns. Clinic hours run from 8:30 AM to 1:00 PM and 3:00 PM to 6:30 PM, offering a schedule that accommodates patients around work and school commitments. The clinic is closed on Wednesdays, Sundays, national holidays, and during the New Year period. For patients presenting with cold symptoms such as fever, sore throat, or cough, the clinic has established a dedicated Fever and Cold Outpatient service requiring advance telephone consultation and appointment booking, demonstrating their commitment to infection control and minimizing contact with general patients. As a community-based internal medicine clinic, they provide comprehensive care ranging from routine health management to acute illnesses. Please note that payment is cash only, so it is advisable to be prepared in advance.
