Located in Kenkyugakuen, Tsukuba City, Ibaraki Prefecture, Igarashi Dental Clinic is conveniently situated a 5-minute walk from Kenkyugakuen Station on the Tsukuba Express. The clinic's most notable feature is that the director is a board-certified periodontist—one of only 18 such specialists in Ibaraki Prefecture. A periodontist is a dentist who has completed over five years of specialized training after dental school, acquired advanced knowledge and skills, and passed the specialist board examination, making them experts in providing high-level periodontal treatment. Periodontal disease is the leading cause of tooth loss in Japan, and since it often progresses without noticeable symptoms in its early stages, having a professional diagnostic and treatment system is a significant strength. In addition to periodontal treatment, the clinic offers preventive dentistry, general dentistry, and pediatric dentistry, embracing its role as a community family dentist. The clinic emphasizes counseling and values dialogue with patients throughout the treatment process. With English-speaking staff and on-site parking, the clinic provides an accessible environment that meets diverse patient needs.
