Little wonder Sarah Watterson is in great shape. As operations manager of The Spa at Tokyo's Mandarin Oriental Hotel in Nihonbashi, she not only has a hand in the best beauty treatments available; she can take a chunk of credit for the hotel spa being recently voted the best day spa in Asia.

Described as "a heavenly place in the sky" -- elevators carry customers to a serene world 36 floors high, where expert therapists apply both Asian- and Western-inspired treatments, and five private spas ease away aches and pains from even the most tired-out tourist and beleaguered corporate body.

"Every customer is taken on a personal journey to improved well-being, depending on needs," Watterson says.
