Clinic For Ikebukuro is an internal medicine clinic located in Minami-Ikebukuro, Toshima Ward, Tokyo, offering English support, credit card payment, and electronic payment options. The clinic provides both insurance-covered and self-pay treatments, and as part of promoting medical DX, it requests patients to present their My Number Card (My Number Insurance Card) in principle. By using the My Number Insurance Card, past medication history and specific health examination information can be shared with doctors, enabling more accurate diagnosis and smoother prescribing. Conventional health insurance cards can also be used, but the use of My Number Insurance Card is recommended. At Clinic For Group, internal medicine and allergy departments accept patients aged 10 and above, while the dermatology department accepts those aged 6 and above, and all consultations can be made without reservations. Walk-in visits are possible, but since priority is given to patients with reservations, using the web reservation system can reduce waiting time. Combining web reservations and online consultations further shortens waiting time, and for first visits, it is recommended to arrive about 10 minutes before the scheduled appointment time as electronic medical record registration takes time.
