Information disclosure system


  1. Information Disclosure System is about providing through distribution or announcement the information that a public organization manages as what it has officially created or obtained and is required to possess through specified procedures such as reading, copying and/or reproduction at the request of a citizen who is a consumer of the information. While the former is dubbed ’requested disclosure’, the latter is called ’provision of information’.

Types of Disclosure

  1. Requested disclosure: It is a procedure for disclosing to a requester the information that a public organization manages as what it has officially created or obtained. (e.g., a request for reading and/or copying of official government documents etc.)
  2. Provision of information: It is the provision that a public organization which possesses information provides it voluntarily or as legally required. (e.g., provision of information through the Internet, distribution of published materials etc.)


  1. Medium-specific types of information: They include paper-based information such as documents, pamphlets, reports, and statistics, and other types including pictures, maps, drawings, photos, films, microfilms, slide film, and computer-processed data.
  2. Content-specific types of information: They include public documents such as legal documents, instructions, notices, displays, resident complaint, and ordinary documents, and administrative publications such as investigation report, research report, statistic report, white paper, and promotional materials.

As for general drafts, however, matters which haven’t completed decision-making such as approval, and ordinary materials like various specialized books and popular culture books are not to be disclosed.
