Kasahara Dental Clinic, located in Nihonbashi Ningyocho, Chuo Ward, Tokyo, is a historic dental practice that has served the local community for over 90 years since its establishment in 1932. Having provided care across three generations at the same location, the clinic features a staff comprised of graduates from the Tokyo Medical and Dental University Faculty of Dentistry, with refined technical expertise cultivated in the Crown and Bridge Prosthodontics Department. Physicians with specialist and instructor certifications are also on staff, ensuring a high level of professional expertise. Additionally, all prosthodontic restorations for self-funded treatments are fabricated by in-house dental technicians, pursuing high-quality outcomes in both precision and aesthetics. The clinic is certified as an "Enhanced Primary Care Dental Clinic," a qualification held by only about one in ten dental practices nationwide, enabling patients to receive periodontal maintenance treatment within insurance coverage. Furthermore, since 2023, the clinic has expanded its treatment options to include removable clear aligners in addition to traditional wire orthodontics. In 2024, the clinic was registered as a medical cooperation facility of The University of Tokyo Hospital, establishing a framework for collaboration with more advanced medical care. Consideration for patient convenience is also evident, with support for credit card and electronic payments, as well as barrier-free facilities.
