National Diet Library

The National Diet Library is Japan’s national library, serving as the country’s largest repository of information and research materials. Established in 1948, it provides access to a vast collection of books, documents, and digital resources for government officials, researchers, students, and the public. Its primary role is to gather, preserve, and provide information that supports government operations and public knowledge. Located in Tokyo, it functions similarly to the Library of Congress in the United States, playing a vital role in Japan’s intellectual and cultural preservation.
