Welcome to the social research data archive “RUDA”!


With the understanding that social research data are valuable public resources, RUDA engages in collecting, assorting, and preserving social research data in order to make it broadly available for academic and educational use.


RUDA is managed by the Center for Statistics and Information (CSI) at Rikkyo University in Japan. An introduction of RUDA in CSI is available HERE.

Note: The majority of archived data is presented in Japanese, and RUDA does not provide English translations of Japanese questionnaires. We hope that researchers with no knowledge of Japanese use RUDA data with the assistance of someone who is fluent in Japanese.
