If you are into tea utensils, you probably know about Hatakeyama Memorial Museum of Fine Art in Tokyo.
The founder, Isse’i Hatakeyama (1881―1971), was a descendant of the Hatakeyama family, the feudal lord of Noto Province. While managing his company, Ebara Corporation, he called himself “Soku’o’u (即翁)” and pursued classical interests, such as noh and chanoyu. To show his art collection, he opened the museum in its current location in October 1964.
I have been there a few times. Every time without fail I am impressed by the stellar collection of fine utensils. Living so far away from Tokyo, it is unfortunate that I cannot visit more of their seasonal exhibits.
