The is a private museum established in October 1964 in Tokyo, Japan.
In October 2024, the museum was renamed the Ebara Hatakeyama Museum of Art. The museum reopened on 5 October 2024 after having closed for renovations.
The first museum director, Hatakeyama Issà(28 December 1881 - 17 November 1971) was the founder of Ebara Corporation. In 1937, Hatakeyama purchased the landlot once Count Terashima Munenori resided, and relocated and rebuilt an old guest house from Hannyaji in Nara which he named "Hannyaen", where a house warming tea ceremony was held in 1943. As Hatakeyama practiced Hà Âshà  school noh since he was young, he acquired a private noh theater and reassembled on the property. There are noh costumes among the collection.
Hatakeyama's collection was moved to a museum he built in 1964 next to his residence as he planned to preserve it for many years and hold exhibitions for the public as well as support researchers.
There is a tea house called Shà Â-an in the museum building, and those in the garden are for rent; Sara-an, Sui-an, Meigetsuken, Shin zashiki, Jà Ârakutei and Bishamondà Â. Once a year, a guided tour is held to visit those tea houses.
The museum holds four exhibition each year. Centered on tea utensils, the collection consists of old Japanese, Chinese and Korean works of art such as paintings, calligraphic writings, pottery, lacquer items and Noh costumes. Of the circa 1,300 objects in the collection, 6 are National Treasures and 32 have been designated as Important Cultural Properties of Japan.
The museum has published a number of books about its collection and special exhibitions:
