• About the Open Data initiative

        The Japanese government is promoting the Open Data initiative, in which the government widely discloses public data in machine-readable formats and allows secondary use of the public data for profit-making or other purposes. This initiative has the goals of improving people's lives and stimulating corporate activities, thereby contributing to social and economic development of Japan.
        This website serves as a catalog of this Open Data, and is intended to provide information about public data available for secondary use. The website provides extensive search capabilities.

If you have any questions about how to use the site, please submit your questions via the Contact page.
