Museum of the Imperial Collections
皇居三の丸尚蔵館（こうきょさんのまるしょうぞうかん、英: Museum of the Imperial Collections）は、東京都千代田区千代田の皇居東御苑内にある、国立文化財機構が所管する博物館施設。 昭和天皇崩御後の1989年（平成元年）6月に遺族の明仁と香淳皇后から寄贈され国庫に帰属した美術品を保存、研究、公開するための施設として、1992年（平成4年）9月に宮内庁所管の博物館「三の丸尚蔵館」として皇居東御苑内に建設され、1993年（平成5年）11月3日に開館した。開館以後も皇族からの寄贈により収蔵品が度々追加されており、現在の収蔵点数は9,800点。 2019年（平成31年/令和元年）度から収蔵庫と展示室を拡張するために建て替え工事が始まり、2023年（令和5年）年10月に宮内庁から国立文化財機構に移管され、同機構を所管する文化庁が収蔵品の管理を行う体制に改められた。2023年（令和5年）11月3日に建て替えられた第I期棟が開館して施設の正式名称が「皇居三の丸尚蔵館」に改められ、2025年（令和7年）5月からの一時休館を挟んで、2026年（令和8年）秋に旧館跡地に第II期棟が完成して全面的に再開館する予定である。
History & Cultural Significance
The Museum of the Imperial Collections, also known as Sannomaru-Shōzōkan, is a treasure trove of Japan's imperial heritage. 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.
What to See & Do
Visitors can explore a rotating selection of artifacts that highlight the artistic and historical richness of Japan. Exhibits often include rare kimonos, Buddhist relics, and exquisite ink paintings, each offering a glimpse into the refined tastes of the imperial court.
While the museum is temporarily closed for renovations until Fall 2026, its permanent collection remains a testament to centuries of craftsmanship and tradition. The surrounding East Garden, with its serene ponds and meticulously maintained landscapes, is a must-visit in its own right.
Atmosphere & Experience
Walking through the East Garden before or after a visit to the museum offers a peaceful escape from the city’s hustle. The quiet elegance of the space, combined with the museum’s curated exhibits, creates an atmosphere of reverence and contemplation.
