Niwa Dental Clinic, located in Tsujimachi, Kita Ward, Nagoya City, is an accessible dental clinic with on-site parking and barrier-free access. The clinic offers English-speaking services and provides children's clear aligner orthodontics for patients aged 6 to 10. This orthodontic method involves wearing soft prefabricated aligners for one hour during the day and while sleeping, which is expected to reduce both physical burden and treatment costs for children. The reception system supports My Number cards, and health insurance cards continue to be accepted. The clinic is closed on Thursdays and Sundays, as well as during year-end and New Year holidays, Golden Week, and the Obon period. The official website regularly updates information about holiday closures, including year-end and New Year and summer holidays.
