Current Digitization of Official Publications in Japan

The National Diet Library acquires official publications from the national government and municipal governments throughout Japan primarily by means of the legal deposit system. These publications are widely used by legislators during deliberations on national politics as well as for other purposes. They are also sent by the NDL in our international exchange program with foreign institutions in return for their publications.

Japanese government agencies have in recent years increasingly published information in digital format. The following websites provide access to digital publications that are useful both for international exchange programs and for general use.

  • National Diet Library Digital Collections
    In this service, users may search for and browse digital materials which are collected and archived by the NDL. This database provides digital publications (books, periodicals, articles, etc.) which the NDL acquired and archived from the websites of Japanese ministries and agencies.
    Major publications such as white papers, which are also distributed as exchange materials, are accessible via this website. A list of publications which are accessible via the NDL Digital Collections is attached for your reference.
  • Web Archiving Project
    The NDL has conducted a large scale acquisition of websites of public organizations in Japan, including the Japanese government, since 2002. This project archives entire websites, including e-books, e-magazines and e-journals, and users are able to access information previously published by national and municipal organizations. Major publications such as white papers and official bulletins from prefectures were also acquired by WARP and archived in the NDL Digital Collections. Every website of public organizations from which data was acquired is included in WARP.
    If what you are looking for is not available in the NDL Digital Collections, please look for it in WARP.
  • NDL Search
    If what you are looking for cannot be found in either the NDL Digital Collections or WARP, please refer to the NDL Search. The NDL Search enables integrated search of about 100 databases including the NDL and other public libraries, archives, museums, institutes of academic research. It also provides data in RSS and OAI-PMH format.
