Park Hyatt Tokyo takes up the top 14 floors of one of the Tokyo's tallest skyscrapers - the Shinjuku Park Tower - so you'd expect the views to be good. Even the gym, which is available only to guests or members of the hotel's exclusive Club on the Park Spa, doesn't disappoint. Situated on the 47th floor it makes the most of its lofty position with floor-to-ceiling windows revealing Japan's bustling metropolis  in all its glory below and as far as more tranquil snow-capped Mt Fuji.  Serious gym junkies will also appreciate the complete range of Life Fitness weight training and fitness equipment. Personal trainers are also available to tailor a workout program to suit your needs during your stay and beyond plus there are group activities, like tai chi, body sculpting and step aerobics, scheduled weekly.  On the same level next door is a 20-metre four-lane indoor heated pool with lounge area where refreshments are served, plus an aerobics studio with body sonic flooring system. Two levels below is the state-of-the-art spa.
