Located in Mizusawa, Oshu City, Iwate Prefecture, Chiba Dental Clinic is a dental clinic operated by the medical corporation Hyakuseikai. Dr. Masayuki Chiba, the clinic director, established the practice in the local area after gaining research and teaching experience at a graduate school, and has been supporting the community's oral health for over 25 years. The clinic's treatment philosophy focuses not merely on superficial improvement of symptoms but on investigating the root causes of problems to prevent recurrence. Additionally, they practice 'narrative-based medicine' that respects each patient's life background and values, with a notable emphasis on supporting long-term health maintenance and care with a 10-20 year perspective. Each patient receives a 60-minute appointment in private treatment rooms, allowing for a relaxed environment. They implement 'visualization' by taking intraoral photos before and after treatment to share treatment goal images, showing thoughtful touches throughout that help patients feel at ease. English support is available, and they accept credit cards and electronic payments. The facility has a dedicated parking lot for 30 vehicles and barrier-free design, creating an accessible environment for diverse patients.
