Museum of the Imperial Collections, Art museum in Chiyoda, Tokyo, Japan

The Museum of the Imperial Collections, known in Japanese as the Sannomaru Shōzōkan, stands in the East Gardens of the Imperial Palace. Its first-phase building, opened in 2023, has a sharply angled overhanging roof edged in pale green metal, white panelled walls cut with rows of short vertical slits, and a glass balcony projecting from one side. Gold lettering on a dark wall beneath a black canopy names the museum.

The museum opened in 1993 after the Emperor and Empress donated a large portion of their personal art collection to the Japanese state in 1989. Later additions included pieces from the estate of Princess Chichibu and the family of Prince Mikasa.

The collection includes a six-panel folding screen from the 16th century depicting Chinese lions in gold pigment. Visitors can see handscrolls from the Kamakura period dating to the second half of the 13th century that illustrate historical events.

The building sits within the East Gardens of the Imperial Palace, reachable from Otemachi Station by walking about five minutes through the Ote-mon Gate. Exhibitions rotate several times a year, so visiting in different seasons offers new displays.

The museum's collection lay outside Japan's Cultural Properties Protection Law by custom, so none of its works were designated National Treasures until 2021, when five pieces received the status at once, among them Itō Jakuchū's 30-panel Dōshoku sai-e and the Mongol Invasion Scrolls.
