Of all the residences realized by the Works Bureau of the Imperial Household Ministry, the museum's main building, with its principal rooms designed by key Art Deco figures such as Henri Rapin and René Lalique, is certainly the most distinctive. In recognition of this, the building was officially designated an Important Cultural Property by the Japanese government in 2015.
The gardens (or teien, which give the museum its name) remain virtually unchanged from the time when the grounds served as an imperial residence. The open expanses of grass and the Japanese garden, with its pond and miniature hills, provide the ideal spot to savor the delights of the changing seasons, including the spring cherry blossoms and autumn leaves. The museum aims to continue offering visitors the opportunity to enjoy works of art in such surroundings by both preserving precious cultural heritage and striving toward the creation of new experiences and values.
