Archives and Mausolea Department, Imperial archive division in Chiyoda-ku, Japan
The Archives and Mausolea Department is an administrative section within the Imperial Palace grounds in Chiyoda-ku that manages historical documents and imperial records. It includes both research facilities with cataloged materials and burial sites of emperors and empresses.
The department was established in 1949, replacing the earlier Zusho-ryō and Shoryō-ryō organizations. This restructuring modernized imperial record management after World War 2.
The department holds ancient manuscripts and palace records that document the continuity of the imperial line. Visitors can sense the deep connection between these archives and Japan's royal heritage.
Researchers must request visits at least 10 days in advance and can access up to 60 items through the Reading Room at Kitahanebashi-mon Gate. Access is limited to registered users who need prior approval from administration.
The department operates with a specialized cataloging system that divides its collection into 12 sections. Visitors access reproductions of original manuscripts rather than the originals themselves to protect these irreplaceable items.
