Ohisama Dental Clinic, located in Junan, Matsumoto City, Nagano Prefecture, is a fully private-pay dental practice dedicated to "whole-body dentistry." Director Dr. Hiroshi Aoki brings experience from general hospital practice and has spent over 20 years refining a distinctive approach that focuses on the systemic impact of dental treatment. The clinic's hallmark is its comprehensive assessment process, which includes an 80-item detailed medical questionnaire along with multifaceted diagnostic methods such as O-ring testing and electromagnetic response testing to evaluate the overall condition of the body. Treatment is fully customized for each patient, covering occlusal adjustment, material selection, and prosthetic structure, enabling the kind of meticulous care that is difficult to achieve under insurance-based dentistry. While the clinic adopts a metal-free philosophy as a baseline, material selection is guided by biocompatibility testing to ensure suitability for each individual—an approach that places the balance of the whole body, not just the teeth, at the core of its treatment philosophy. Consultations are available on weekday and Saturday mornings (9:00–12:00) and weekday afternoons (14:00–17:00), with English-language support also offered. The clinic accepts credit cards and electronic payments, and a dedicated parking lot with seven spaces is available, making it convenient for patients traveling from a distance.
