In October this year, management of the museum was transferred from the Imperial Household Agency to the National Institutes for Cultural Heritage to enhance the exhibitions. The museum currently houses about 6,100 items, including eight national treasures. In the first of the four phases of the commemorative exhibition, four national treasures will be displayed, including Ito Jakuchu's (1716–1800) representative work "Doshoku Saie" (Colorful Realm of Living Beings) and "Moko Shurai Ekotoba" (Illustrated Account of the Mongol Invasions).
