Tokyo Metropolitan Teien Art Museum

Art deco museum with various exhibits

First of all, before you even take the exhibits into account, the Tokyo Metropolitan Teien Art Museum is in a gorgeous art deco style building which is worth appreciating in and of itself. They have various exhibits on throughout the year (I recommend visiting their website at https://www.teien-art-museum.ne.jp/en/ to check before you go), and there is also a beautiful garden (an extra fee of 200 yen applies) and teahouse on the grounds if you want to spend some extra time enjoying those.
