The Use of Official Statistical Micro Data in Academic Research and Higher Learning

The Statistics Act, fully enforced in April 2009 (Act No. 53 of 2007, hereinafter referred to as the “Statistics Act”), placed statistics as the foundation of information for society and established a system to promote the effective use of statistical data.
An amendment to the Statistics Act was enforced in May 2019, and the use of services offering official statistical micro data became more widespread.
The Research Centre for Information and Statistics of Social Science at the Institute of Economic Research, Hitotsubashi University, in collaboration with the National Statistics Center, will promote the provision of official statistical anonymized data for researchers and others conducting academic research.

*Please refer to the National Statistics Center website regarding collaboration with the National Statistics Center and secondary use of official statistical data.


Effect on Operations by the COVID-19 Outbreak

As a measure against the spread of COVID-19, entry into the University is restricted.

Thus, inquiries regarding use of micro data are accepted by email as usual, but for issues that require face-to-face meeting such as user authentication for first-time use of anonymized data, we request your patience until the restrictions are lifted, and we expect that handling of matters will take considerably more time than usual.

If you have any questions, please contact us at the email address below.

When Making an In-Person Visit

As representatives may be engaged in other business and unavailable at times, please be sure to make an appointment by email in advance of making a visit.
In particular, return of anonymized data in person cannot be processed without an appointment made in advance. (As it violates the terms of use and other conditions, please refrain from handing anonymized data for return to another staff member and requesting it be passed on to the person in charge. ) We apologize for the inconvenience but appreciate the cooperation of all including those within the university.
