Located in Okusawa, Setagaya Ward in Tokyo's Jiyugaoka area, Kyōsei Jiyūgaoka Shikashitsu is a clinic specializing in orthodontics. A notable feature of their practice is their fundamental policy of "non-extraction orthodontics." While many conventional orthodontic treatments involve tooth extraction to create space for proper alignment, this clinic analyzes the underlying causes of misalignment from multiple angles and explores treatment methods that restore beautiful teeth and proper bite without extracting teeth whenever possible. The clinic director is an orthodontic specialist with graduate-level teaching experience, developing individualized treatment plans based on extensive clinical expertise and theoretical foundations. The clinic actively incorporates advanced technology such as dental CT and 3D scanning systems for diagnosis and treatment, achieving high-precision orthodontics while minimizing patient burden. Regarding fees, they follow pricing standards aligned with Tokyo Medical and Dental University, where the director graduated, maintaining a transparent pricing system that presents the total cost before treatment begins. Clear aligner treatment is also available for those preferring less visible orthodontic options. The clinic accepts credit cards and electronic payments, and features barrier-free facilities and parking.
