Located in Takaban, Meguro-ku, Tokyo, Osawa Dental Clinic is a dental practice offering services in English. Dr. Hayato Osawa, the clinic director, pursued dentistry guided by a craftsman's spirit believing that "effort returns to oneself" and a dedication to patient contribution. The practice is founded on five philosophies advocated by Dr. Beach from the United States, featuring a comprehensive approach that goes beyond mere symptom treatment. These five principles progress in stages: beginning with eliminating pain and discomfort, followed by establishing and maintaining oral hygiene, enhancing tissue resistance to boost immunity, adjusting the mechanical balance between upper and lower teeth, and finally creating an aesthetic appearance as the ultimate goal. The clinic's brushing instruction incorporates techniques to boost immunity beyond simple plaque removal, and the "HC=0" philosophy—aiming for patients to independently maintain their health—is consistently applied throughout all treatment. Clinic hours are 10:00 AM to 7:00 PM on weekdays and Saturdays (with a lunch break), closed on Thursdays, Sundays, and national holidays.
