Arita Dental Clinic, located in Shinjuku 4-chome, Shinjuku-ku, Tokyo, just a 2-minute walk from the Shinjuku Shinnan-guchi and Minami-guchi exits, has been providing community-based dental care since its establishment in 1998. What sets the clinic apart is its approach that goes beyond simply treating teeth and oral conditions, encompassing the patient's overall health. In recent years, medical research has increasingly pointed to the link between periodontal disease and systemic conditions, and the clinic draws on this knowledge, operating under the principle that oral health directly affects one's overall quality of life. The clinic also places strong emphasis on counseling and thorough explanations, creating an environment where patients can fully understand treatment options and proceed with confidence. For those who feel anxious or nervous about dental treatment, Arita Dental Clinic offers a welcoming space where consultations feel approachable. Hours are 10:00–13:00 and 14:00–19:00, primarily on weekdays. The clinic is closed on Thursdays, Sundays, and national holidays, with additional closures during the year-end and New Year period. Situated in the highly accessible Shinjuku area yet committed to long-term, patient-centered care, the clinic reflects a sincere and thoughtful approach to healthcare.
