From the National Librarian’s Welcome Message:

The National Diet Library was established based on the National Diet Library Law in February 1948, as an institution to serve the newly installed Diet assembly and the nation in the dynamic age of post-war reconstruction. The preamble of the NDL Law, which states that it was “hereby established as a result of the firm conviction that truth makes us free and with the object of contributing to international peace and the democratization of Japan as promised in our Constitution” denotes the underlying ethos of the NDL. The Law also stipulates the still relevant institutional mission that it assists the Diet members as the parliamentary library, and the whole nation as the national library.
