Located in Takakuradai, Minami-ku, Sakai City, Osaka Prefecture, Yagi Clinic is a pediatric clinic offering English services, parking, and barrier-free accessibility. The clinic treats children's illnesses, injuries, burns, and general health concerns, providing care not only to children but also to high school students and older patients. The clinic's treatment philosophy emphasizes home care that respects children's natural healing abilities, avoiding unnecessary prescriptions of cough suppressants, nasal decongestants, antipyretics, or antibiotics for colds. This approach supports parents in confidently managing care at home. The clinic places strong emphasis on infection control—patients with suspected infectious symptoms such as fever or rash are guided through a separate entrance from the main entrance, and all services from reception to payment are provided in a private examination room with windows for constant ventilation. The clinic offers rapid antigen tests for influenza, streptococcal infection, adenovirus, RSV virus, and COVID-19, and can perform blood tests, X-rays, ultrasounds, and pulmonary function tests. A distinctive feature of the clinic is allergy specialist care, treating conditions requiring long-term management such as atopic dermatitis, food allergies, bronchial asthma, and hay fever. For atopic dermatitis, the clinic advises on ointment selection based on symptoms and skincare methods; for food allergies, blood tests are performed as needed, and food challenge tests are conducted in-house. For bronchial asthma, treatment and daily life advice are provided through pulmonary function tests and blood tests, with online consultations available when conditions are stable.
