Johoku-Ya Dental Clinic is a dental facility located in Yamagoshi, Matsuyama City, Ehime Prefecture, with preventive dentistry as an important concept. To maintain oral health, the clinic provides treatment that always focuses on preventing diseases throughout the entire mouth, rather than simply treating individual teeth. Based on the belief that dental care without considering cavity and gum disease prevention is counterproductive to health improvement, the entire staff continues to develop their skills to provide high-quality medical technology and information. Operating hours are from 9:00 to 13:00 and 14:30 to 19:30, with a lunch break in between. Closed days are Thursday and Saturday afternoons, Sundays, and national holidays, but on weeks with national holidays, afternoon consultations are also conducted on Thursday. The clinic provides English support, has parking facilities, and offers barrier-free access.
