Mandarin Oriental, Tokyo
Occupying the top nine floors of the glistening Nihonbashi Mitsui Tower, this modern hotel has harmonious rooms, tastefully decorated in shades of brown and featuring such touches as down bedding, luxury linens, in-room newspaper delivery, and large picture windows with city-lights panoramas. Corner rooms have sunken marble tubs that allow you to gaze out windows while soaking. The spa, with its signature body scrubs and massages, and the gym are top-of-the-line. The award-winning restaurants offer modern or traditional cuisine, but if you're suffering extravagance overload (and the accompanying prices) you can take a short stroll toward Tokyo Station, with its variety of tiny watering holes and izakaya (Japanese pubs).
