Sansan Clinic, located in Naokawa, Wakayama City, is a medical facility offering both otolaryngology (ENT) and pediatric care. A notable feature of this clinic is that both a board-certified ENT specialist and a board-certified pediatrician are on staff full-time. When a child catches a cold, upper respiratory symptoms are typically handled by ENT and lower respiratory symptoms by pediatrics — but at this facility, patients can be seen by specialists in both fields in a single visit. The pediatric department treats common cold symptoms such as fever, cough, and runny nose, as well as allergic conditions including bronchial asthma and atopic dermatitis, and gastrointestinal issues such as vomiting and diarrhea. Consultations regarding children's health, growth, and development are also welcome. Dedicated vaccination hours are available (Monday, Tuesday, Wednesday, and Friday, 2:00–3:30 PM), and vaccinations can also be administered during regular consultation hours. The clinic is fully barrier-free and equipped with a kids' play area, a nursing corner, child-height sinks, and child-sized toilets. Infection control is taken seriously, with a dedicated waiting room and examination room for patients with high fever or suspected contagious illnesses such as influenza. An online appointment system is in place to help reduce waiting times. English-language support is available. The clinic provides a dedicated parking lot with 13 spaces and a covered bicycle parking area. Hours are 9:00 AM–12:00 PM in the morning; afternoon hours are 3:30–5:30 PM for pediatrics and 3:30–6:30 PM for ENT. The clinic is closed on Sundays and public holidays.
