Open data of local governments

Materials such as a list of local governments that have worked on open data are posted.

Method of Data Disclosure in the Guidelines for the Promotion of Open Data by Local Governments

Data can be disclosed on websites operated by local governments (open data websites are established as part of official websites or separate websites that are independent from official websites), on websites operated by the Cabinet Office and Ministries, on websites operated by private organizations, and by creating data catalog sites with cross-sectoral search functions.

When publishing on a site other than the official site, it is necessary to present the fact that the external site is used and the URL, etc. of the data disclosure destination on the official site so that the user can easily access the data.
