Promoting Data Deposit in SSJDA: Introducing the Improvements in Our New Data Management System

The Social Science Japan Data Archive (SSJDA) is an institution that collects and stores raw data from statistical and social surveys for safekeeping, and provides access for its secondary use in academic endeavors. It is a core part of the Center for Social Research and Data Archives (CSRDA) in the Institute of Social Science at The University of Tokyo. To support empirical research in the social sciences in Japan, data collection and storage in SSJDA have been smoothly conducted since 1996. Nearly 200 institutions, organizations, and individual researchers have deposited data with SSJDA, and over 2000 data sets have been made available in the public domain thus far. CSRDA was designated as a “Joint Usage/Research Center” by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) beginning in 2010, and was selected for the Promotion of Science Humanities and Social Sciences Data Infrastructure Construction Program by the Japan Society for the Promotion of Science (JSPS) in 2018. Through this program, we have improved SSJDA Direct (Data Download System) and added an online function for a deposit procedure which allows depositors to check the status of their data cleaning and usage from their personal page. It is possible to increase the level of convenience enjoyed by depositors, as well as to increase the quantity of data that is deposited and shared with SSJDA. The improvement of SSJDA Direct contributes to research in the humanities and social sciences in Japan, and will lead to the development of data archives in the future.
