Located in the mountainous Koyadaira district of Mima City, Tokushima Prefecture, the Mima City National Health Insurance Koyadaira Dental Clinic is a publicly operated dental facility run by the city. As a designated remote area medical institution, the clinic provides dental care to residents of mountain communities with limited transportation access. Consultations are held once a week on Wednesdays only, from 9:00 AM to noon and from 2:00 PM to 5:00 PM in the afternoon. Despite its limited operating days, the clinic plays a vital role in supporting dental healthcare in the region. The clinic offers general dentistry services, and in addition to standard dental treatments, also conducts health promotion programs, awareness campaigns, and home visit services for patients who have difficulty commuting, providing multifaceted support for the oral health of local residents. The facility is equipped with a parking lot, accommodating the mountain location where car access is the primary means of transportation. The clinic is also barrier-free, making it accessible for elderly individuals and those with physical disabilities. English-language support is available, allowing those who require communication in languages other than Japanese to consult with ease. As a community-rooted public medical institution, this clinic serves as the hub of dental care in the Koyadaira district.
