Ishii Children's and Internal Medicine Cardiology Clinic is a medical clinic located in Matsunogi, Suginami-ku, Tokyo, with two doctors providing care: a pediatric specialist and an internal medicine certified physician/cardiology specialist. The clinic inherited the history of Ishii Pediatrics and Internal Medicine Clinic, which operated in this area from 1969 to 1982, and reopened under a new name in October 2006. Appointments are accepted for pediatrics and infant health checkups. First-time patients are advised to fill out the pediatric initial visit questionnaire at home and bring it with them for smoother registration procedures. If a fever is observed within 48 hours, patients are advised to contact the reception in advance. The clinic also features English support, on-site parking, and barrier-free accessibility. Closed days are Sundays, holidays, and the New Year holiday period from December 29 to January 4.
