In order to promote digitalization in the whole country, it is essential to develop digital infrastructure as a social infrastructure. In Digital Agency, in order to promote information cooperation between administrative agencies and data utilization including private sector, as a base registry, we are promoting the development and utilization of data-groups that are the foundation of society.

What is the base registry?

A base registry * is a database consisting of data that can be referenced in many procedures across systems, such as addresses, locations, and names of corporations. The development of a base registry will contribute to improving the convenience of citizens and the efficiency of administrative operations. The development of a base registry will make various procedures more convenient, such as eliminating the need to obtain documents such as certificates, eliminating the need for manual input, and eliminating the procedure itself.
*The official legal name of the base registry is defined as the "Public Basic Information Database." In order to develop and improve the base registry in a planned and comprehensive manner, Digital Agency submitted an amendment bill (a bill to partially amend Basic Act on the Formation of a Digital Society, etc.) to the 213th ordinary session of the Diet, which was passed on May 31, 2024.

On June 13, 2025, the Cabinet approved the "Act on the Advancement of Government Administration Processes That Use Information and Communications Technology Public Basic Information Database Development and Improvement Plan " as stipulated in the Digital Government Promotion Act (). In the future, we will develop, improve, and promote the use of the database based on the plan.
