Located in Koenji-Minami, Suginami International Clinic focuses on community health promotion and preventive medicine as a specialized internal medicine clinic. Operating on an appointment-only system, first-time patients are required to book in advance via email or LINE. To accommodate busy working adults, morning consultation slots are available starting at 7:00 AM. Priority appointment slots are available for patients with referral letters from university hospitals or other medical institutions. The clinic also provides treatment for COVID-19 aftereffects and vaccine-related health issues, as well as subsidized shingles vaccinations. As part of COVID-19 infection control measures, the latest air purification systems have been installed to ensure a well-maintained treatment environment. The clinic is closed on weekends, national holidays, and during the New Year period. Medical certificates may not be available for patients who interrupted treatment for personal reasons or if more than one month has passed since their last visit. Cancellation fees and appointment change policies are in place to ensure smooth clinic operations.
