ISSP belongs to the University of Tokyo. At the same time, its facilities are open to all domestic researchers participating in joint research. In April 2010, ISSP was granted the authorization to become a joint use/research center.

ISSP currently consists of four Research Divisions, two Research Groups, five Research Facilities, Visiting Professors and Foreign Visiting Professors. Among these, Synchrotron Radiation Laboratory has a branch at the SPring-8 synchrotron in Hyogo and the Neutron Science Laboratory maintains spectrometers at the research reactor of the Japan Atomic Energy Agency and at J-PARC/MLF in Ibaraki. Apart from the Research Divisions and Facilities, supporting facilities that include the Cryogenic Service Laboratory, the Machine Shop, the Radiation Safety Laboratory, the Library and the International Liaison Office, provide services to both in-house and outside users. The Public Relations Office offers various information on ISSP activities, and the Information Technology Office handles network-related matters, and Counseling Services provide brief counseling and referral services to students, faculty, and staff.

Administrative decisions are made at the faculty meeting chaired by the director and attended by professors and associate professors. The ISSP Advisory Committee, consisting of nearly equal number of members from the University of Tokyo and from outside to represent the interests of the broader community, gives advice on various aspects of administration upon inquiry of the director. The Advisory Committee for Joint Research, consisting of both the in-house and outside members, evaluates proposals for joint research and workshops, allocating funds for user activities. The Research Strategy Office headed by the director proposes future plans to reinforce the research and management of ISSP.

ISSP recruits all positions for professors, associate professors, and research associates openly. ISSP`s hiring of professors and associate professors is decided in a Faculty Meeting. Prior to the Faculty Meeting, the Personnel Selection Council, (composed of approximately an equal number of members from inside and outside of ISSP), reviews all candidates. ISSP`s final hiring decisions of research associates positions are also decided in a Faculty Meeting. Prior to the Faculty Meeting, the Personnel Selection Council makes recommendations after reviewing candidates provided by a selection committee.
