国立国会図書館
The legal deposit requirements for Japan's National Diet Library are specified in Chapters X through XI-3 of the National Diet Library Law. These requirements vary based on whether the publishing entity is governmental or nongovernmental, and on whether the work is published physically or online. Required works are books, pamphlets, serials, music scores, maps, films, other documents or charts, phonographic records, and digital text, images, sounds, or programs. Nongovernmental publishers must submit a single copy, and are entitled to "compensation equivalent to the expenses usually required for the issue and deposit of the publication;" noncompliance is subject to a fine.
