Tokyo abounds in skyscraper hotels, but this one takes the honors as the loftiest one of all, in the upper stratospheres of the city's tallest building. The palatial lobby, on the 45th floor, welcomes guests with massive flower arrangements, bold abstract art, and cascading waterfalls, but views are disappointingly restricted to only a few window-side seats in the lobby lounge. Luckily, breathtaking panoramas are handily delivered from guest rooms, which occupy the 47th to 53rd floors and give a choice of compass direction, from Tokyo Sky Tree and Shinjuku toward the north to Shibuya and Mt. Fuji in the west, with maps in each room identifying key landmarks (I'd be hard pressed to say which is best, though those facing east, over the Imperial Palace's gardens and Ginza toward the bay, are interesting). At 52 sq. m. (560 sq. ft.), they're also Tokyo's largest, with a third of the space devoted to bathrooms designed to keep couples happy with their dual sinks, separate tub and shower, and 20-inch TV. Yet little ones, too, are not forgotten, with stations set up at various hotel venues and locations where kids can stamp their individual souvenir card. This is a gorgeous hotel, close to the madness of Roppongi's nightlife but very much removed, a cocoon of refined luxury.
