Usui Internal Medicine Clinic opened in Azabu in 2003 and serves as the local family doctor based in Roppongi, Minato City. The clinic provides comprehensive internal medical care ranging from common illnesses like colds to management of chronic diseases and lifestyle-related conditions. It also offers district health checkups, corporate periodic health examinations, and vaccinations such as influenza. In terms of specialization, the clinic employs specialists certified by the Japan Gastroenterological Endoscopy Society and the Japan Gastroenterological Society, with a comprehensive system for gastrointestinal examinations including gastroscopy and abdominal ultrasound. For endoscopic examinations, the clinic uses thin scopes and strives to provide less invasive, painless testing that minimizes patient discomfort. In the field of cardiology, electrocardiograms and echocardiograms are performed regularly, and a collaborative system with the adjacent Cardiovascular Institute has been established. Examinations are conducted daily, but appointments are generally required, including for health checkups and vaccinations, which can be booked during clinic hours. Clinic hours are from 9:00 AM to 5:00 PM, with consultations held in morning and afternoon sessions. The clinic is closed on weekends, holidays, and during specific periods including year-end/New Year's and summer. For payment, the clinic accepts credit cards, debit cards, and electronic payments, with English language support available.
