OUJ has 50 Study Centers (4 in Tokyo), 7 Satellite Spaces, and 64 Audio-visual Rooms throughout Japan. The Study Centers are used for conducting face-to-face class sessions and credit accreditation examinations. In addition, tutorials and academic counseling are offered at these centers.
There are facilities for students to view or listen to broadcast lectures, and library services are also provided at the Study Centers. In addition, they function as venues for students to hold extracurricular and social activities. The Study Centers are located on the campuses of public or private universities, or in municipal facilities. The Satellite Spaces and Audio-visual Rooms provide easier access to the above-mentioned facilities to those students who live far away from the Study Centers in their prefectures.
