Museum of the Imperial Collections
皇居三の丸尚蔵館
The Museum of the Imperial Collections Sannomaru-Shōzōkan (三の丸尚蔵館) is located on the grounds of the East Garden of Tokyo Imperial Palace. It showcases a changing exhibition of a part of the imperial household treasures. The museum is currently temporarily closed for renovations and will reopen in Fall 2026. The Museum of the Imperial Collections was conceived during the change from the Shōwa period (1926 – 1989) to the Heisei period (1989 – 2019) . The Imperial family donated 6,000 pieces of art to the Japanese government in 1989.
History & Cultural Significance

Located within the East Garden of the Tokyo Imperial Palace, it was established during the transition from the Shōwa to Heisei eras, reflecting a renewed commitment to preserving and sharing the cultural legacy of the Japanese imperial family.
In 1989, the Imperial family donated 6,000 pieces of art, including calligraphy, ceramics, and textiles, to the public. This gesture marked a significant shift in how the imperial collections were made accessible, transforming the museum into a symbol of cultural openness and historical continuity.
