It became Teikyo University in 1966. It is part of Teikyo Group, a multinational educational foundation that also operates language and cultural exchange facilities at pre-university levels in various countries.
The university consists of eight undergraduate facilities, one junior college, and six graduate schools. Five main campuses in Japan are supplemented by several overseas campuses that provide study-abroad opportunities for Japanese students, as well as Japanese-oriented learning for residents of the campuses' home countries. Total enrollment is about 20,000 students. Although the headquarters is the Itabashi campus, the majority of students (approximately 17,000) are enrolled at the Hachiōji campus in West Tokyo.
