Located on the 11th floor of the Marunouchi Building, directly in front of Tokyo Station's Marunouchi Exit, this dental clinic has a history spanning over 70 years since its establishment. Following the renovation of the Marunouchi Building, the clinic offers a bright and clean environment, complete with an operating room and counseling rooms. The clinic provides a wide range of dental services including cavity treatment, periodontal disease treatment, calculus removal, dentures, implants, ceramic crowns, teeth whitening, and wisdom tooth extraction. In August 2015, the clinic underwent expansion and introduced Class B sterilizers, which meet the highest standards, implementing a comprehensive system where all instruments are sterilized for each patient to prevent hospital-acquired infections. The clinic established the Tōkyō Dental Laboratory (Tōkyō Dental Lab), enabling the provision of high-quality prosthetic devices. With a dedicated physician system and well-trained staff, the clinic is structured to allow doctors to focus entirely on treatment. The clinic accepts credit cards and electronic payments, and is equipped with parking and barrier-free facilities. Clinic hours are Monday and Wednesday from 9:30 to 17:30, Tuesday and Friday from 10:00 to 19:00, Thursday from 10:30 to 19:00, and Saturday from 10:00 to 16:00.
