Sophia University's library system contains one million volumes and 11,000 periodicals. The Central Library has open stacks for ease of use while smaller libraries and research institutes contain specialized collections. The library system is especially rich in English books and journals related to the study of Japan. Digital resources include on-line searches of library (OPAC), extensive databases, e-journals, and specialized search engines for journal and newspaper articles.

The GPGS draws on the resources of the Institute of Comparative Culture. The Institute sponsors a lecture series that invites leading scholars in Japan studies and other areas, and prominent international figures, such as Nobel Prize winners, and the heads of international organizations. It also sponsors research projects and seminars, such as: "Globalization of Food Consumption and the Construction of Social Hierarchy" and "Teaching Tokyo."

The GPGS has its own study rooms and computer facilities and provides students with on-campus lockers for storing materials. In addition, graduate students can use the university computing facilities, cafeterias, gymnasium, athletic fields, and medical and counseling facilities. As with urban universities generally in Japan, Sophia has limited dormitory space and most students live off campus.
