Yanagizawa General Internal Medicine Clinic Asakusa is an internal medicine clinic located in Hanakawado, Taito Ward, Tokyo, offering English language support and barrier-free accessibility. The clinic provides preventive administration of anti-influenza medications for influenza virus prevention as out-of-pocket treatment, prescribed when a physician deems necessary after examining the patient. Preventive administration is available for those who cohabit with or have had close contact with influenza patients, particularly those aged 65 and older or with chronic diseases, and it is recommended to start within 48 hours after exposure. Vaccinations are administered on specific Saturdays; however, on the 1st and 3rd Saturdays of each month, regular internal medicine services are suspended as the clinic offers ophthalmology and fever outpatient services concurrently. Starting from December 2, 2024, the clinic supports online eligibility verification using the My Number insurance card, and also provides telephone consultation outside regular hours for patients receiving ongoing treatment. While accepting patients with fever and cold symptoms, the clinic also treats patients at high risk of severe illness, implementing spatial or temporal isolation during medical care.
