The Japan Biographical Database (JBDB) is a database aimed at accumulating information on historical figures related to Japan. Using a modern JavaScript web application, we have set up a PostgreSQL database based on the database construction of the China Biographical Database (CBDB) to accumulate data and edit its functions.

The project is part of the “Project to Build an International Collaborative Research Network for Pre-modern Japanese Texts” (NIJL-NW project)

Note that in order to enter and edit data, you will need to obtain a user account and log in.

  1. To provide access points to information and events on various historical figures related to Japan and the Japanese people.
  2. To use visualization tools in the applications to try to understand the connections between people and organizations, and political and economic networks.
  3. Enrich the functions of the various applications so that they can be used in a wide range of research fields.
