The Nippon Dental University is a private university in Tokyo and Niigata, Japan, established in 1947. The predecessor of the school was founded in 1907. One out of every seven dentists in Japan is a graduate of this school. The Nippon Dental University, Japan's first dental university, was founded by Ichigoro Nakahara in 1907 under the Japanese Dental Law, which introduced regulations for the accreditation of both public and private dental schools. Dentistry was in its infancy at the time, and the purpose of establishing this school was "to foster excellence in dentists as regards their character as well as their scholastic achievements and technique." The school trained students on the medical aspects of the teeth, jaw, and oral cavity, and produced dentists with the necessary academic and technical knowledge as well as an appropriate ethical attitude. It also endeavored to introduce improvements in dental medicine and treatment, and in the general welfare of patients.
