User Registration

The National Diet Library, as the only national library in Japan, is required to eternally preserve publications and materials as the nation's cultural assets that are collected mainly depending on the legal deposit system and to make them available for the people. For this purpose, we ask our visitors to register as users and use the materials in the closed stacks responsibly. We are also trying to improve users' convenience through user registration.
User registration supports you in making full use of our library in these cases, too.
The National Diet Library establishes standards about the protection of personal data and endeavors to handle the data appropriately. Please see the NDL policy on handling personal information for more information.
