Teien Art Museum

東京都庭園美術館Tokyo Metropolitan Teien Art Museum, or Tokyo-to Teien Bijutsukan (東京都庭園美術館), was initially constructed in 1933 as the residence of Asaka-no-miya (Prince Asaka), then a relative of the Imperial family.
He lived in Paris for several years and was fascinated with the Art Deco movement there. So when he returned to Tokyo, he built his house in this design style. After the Second World War, it changed hands several times and ended up being a museum run by Tokyo Prefecture.
As for Japanese elements in this residence, there is a modest Japanese garden with a tea house, so generally speaking, this is not a place to visit in search of "traditional Japan". The whole set of the complex is designated as Important Cultural Properties.
It's a 6-min walk from Shiroganedai Station of the Toei Mita Line or the Tokyo Metro Nanboku Line, or a 7-min walk from Meguro Station of the JR Yamanote Line or the Tokyu Meguro Line.
