Far above the city streets on the 52nd and 53rd floors of the Roppongi Hills building, the Mori Art Museum houses contemporary works by primarily Japanese and East Asian artists in a range of mediums, including photography, design, fashion, architecture, and video installations. There’s also an observation deck on the 52nd floor with an open-air Sky Deck, a lounge, a café, and a restaurant with outstanding views of the city. Keep in mind, though, that there are a myriad other dining options as well on the lower floors of the Roppongi Hills building, one of the tallest in the city.
