Asahi Kokubunji Naika is an internal medicine specialty clinic conveniently located just a 4-minute walk from the south exit of JR Kokubunji Station. Situated on the first floor of the Kokubunji Minami Medical Building, it can be found by heading south along the west side of Tonogayato Park. The clinic is led by Dr. Yoshihiko Yamamoto, who provides general internal medicine services and supports the health of local residents. Consultation hours are from 9:30 AM to 12:30 PM and 2:30 PM to 6:00 PM, with the clinic open on Monday, Tuesday, Wednesday, and Friday (Saturday mornings only). Patients experiencing fever, cough, or sore throat are required to make an appointment in advance—by phone, web, or LINE—as an infection control measure. The clinic also offers a wide range of services including pre-employment health screenings, municipal health checkups, and vaccinations such as the shingles vaccine. Cashless payment is well established, with support for credit cards, electronic money, transit IC cards, and QR code payments. Infection prevention measures are strictly enforced, including mandatory mask-wearing inside the clinic.
