Located in the Kotobira area of Nagaoka City, Niigata Prefecture, Atago Kodomo Clinic operates by separating consultation hours for general visits treating acute conditions from chronic visits treating chronic conditions to prevent infection. For acute conditions, they treat sudden symptoms such as fever, cough, runny nose, sore throat, diarrhea, vomiting, ear pain, hives, rashes, and impetigo. For chronic conditions, they manage long-term illnesses and ongoing prescriptions including bronchial asthma, hay fever, allergic rhinitis, atopic dermatitis, food allergies, constipation, nocturnal enuresis, developmental disorders, chronic headaches, orthostatic dysregulation, and epilepsy. Medical services are provided primarily by Dr. Yoshikawa from Monday to Saturday, with medical care available in multilingual environments including English support. The developmental clinic is available by phone reservation only on Mondays, Tuesdays, Thursdays, and Fridays from 1:30 PM to 2:00 PM, while the allergy clinic is held on the first and third Fridays. Electronic payment acceptance, parking facilities, and barrier-free equipment improve accessibility, and smooth visit procedures are available through the web booking system and pre-completion web questionnaires.
