Iijima Orthodontic Clinic, located in Amanuma, Suginami Ward, Tokyo, specializes in orthodontic treatment. Director Masakazu Iijima graduated from Josai Dental University (now Meikai University School of Dentistry), pursued extensive orthodontic training in graduate school, and obtained certification as a specialist and instructor from the Japanese Orthodontic Society, as well as a Doctor of Dental Science degree. With over 4,000 orthodontic cases treated in approximately 30 years, his extensive experience is a defining feature of the clinic. Treatment philosophy prioritizes avoiding unnecessary extractions, focusing on orthodontic care that respects each patient's natural dental alignment, with an emphasis on clearly explaining treatment options. Dr. Yukari Iijima, also a member of the Japanese Orthodontic Society, provides care alongside the director, creating a professional team-based approach. Consultation hours are available weekday and Saturday mornings and afternoons, with English-speaking support available to meet diverse patient needs. Combining orthodontic expertise with decades of clinical experience, the clinic has earned trust as a community-based orthodontic practice.
