Ishii Orthodontic Clinic is located in Ichigayahachimancho, Shinjuku-ku, Tokyo, and is a dental clinic specializing in orthodontics, conveniently situated about a 4-minute walk from Ichigaya Station on the JR Chuo-Sobu Line and Toei Shinjuku Line, and about a 2-minute walk from Exit 7 of Ichigaya Station on the Tokyo Metro Yurakucho and Namboku Lines. The clinic director graduated from the Faculty of Dentistry at Tokyo Medical and Dental University, trained in the orthodontics department at the same university, and established this clinic in 2001. The director is a member of several professional societies, including the Japanese Orthodontic Society and the Japanese Cleft Palate Association. A key feature of this clinic is its emphasis on orthodontic treatment as medical care, not merely aesthetic improvement, serving patients of all ages from children to adults. Additionally, as a designated medical institution for self-support medical care (growth medical care) and jaw function diagnosis, the clinic provides insurance-covered orthodontic treatment for conditions such as cleft palate and dentofacial deformities, offering advanced specialized care. Appointments are required, the facility is barrier-free, and payment by credit card and electronic payment is accepted. English assistance is available, creating an accessible environment for non-Japanese speakers. The clinic accepts consultations on a wide range of dental alignment concerns, with a system in place for discussing treatment timing, duration, and costs in advance.
