We absolutely love this hotel, which sits on top of the Marunouchi Trust Tower Main and is conveniently close to Tokyo Station. The rooms are elegant with modern majestic décor, and their bathrooms are particularly divine – they have tubs perched beside large windows with soaring views across the city. The Spa transports guests to a little Bali-esque world invigorating all the senses. The pool stretches along the side of the building with big white loungers and a fully equipped gym (you can also rent out gear so there is no need to pack a sports kit). There is also a private hot tub area behind the changing rooms for the ultimate post work-out soak.
