Nagata Dental Clinic, located in Omori-Nishi, Ota-ku, Tokyo, is a well-established practice that has served the community's dental care needs for over 40 years since its founding in 1979, relocating to its current premises in 2020. The clinic's guiding philosophy centers on building a philanthropy-based preventive care system, emphasizing long-term care so that patients of all ages—from children to the elderly—can maintain beautiful teeth and a healthy mouth well into their centenarian years. The clinic places particular emphasis on dental implant treatment, with the director continuously honing expertise through training both domestically and internationally, including in Sydney and Stockholm, to deliver highly precise techniques to patients. A dental CT scanner has been introduced, enabling accurate diagnostics even for complex procedures such as implants and tooth extractions. Private treatment spaces designed with patient privacy in mind ensure a comfortable environment for delicate procedures. The clinic is barrier-free, making it easily accessible for those with limited mobility, and supports electronic payments for added convenience. Weekday hours extend until 7:30 PM, making it easy to visit after work.
