The SSJ Data Archive is a comprehensive archive of social science data concerning Japan.

The SSJDA collects, compiles, and digitizes micro-level data on Japanese society, and offers them for secondary analysis.

Please note that the data sets are provided only in Japanese except some data sets (for detailed information, please visit this site). We believe, however, that the Archive is useful for comparative purposes as well as for Japan studies. Researchers without knowledge of the Japanese language are encouraged to utilize the SSJDA’s resources with the help of Japanese-speaking people.
