Due to COVID-19, university campuses have been closed since April 2020, and campus space usage was restricted. The significance of campus space will be discussed by comparing the campus use by the students before and after the self-restraint. A web-based questionnaire survey was conducted on 6,789 students to identify the actual situation of activities such as classes and interactions, as well as their keen opinions through open-ended responses. Restrictions on campus use lead to the loss of interaction and campus spaces for students to study and to live. This research clarifies the significance of campus space for future campus planning.
