Image: The spa's inspiration is the "journey of water"

Japan's first Evian-branded spa has been unveiled at Palace Hotel Tokyo - part of a US$1.2bn (EUR965m, £771m) mixed-use development in the heart of the city.

Located on the fifth floor of the hotel, the 1,200sq m (12,197sq ft) spa is inspired by the Alpine journey taken by the France-based company's natural mineral water.

Facilities include five treatment rooms and a spa suite - each named after an Alpine peak, as well as heated baths, a marble sauna, a cold plunge pool and a dry sauna.

Men's and women's relaxation lounges also form part of the Evian spa, which boasts views overlooking Tokyo's Imperial Palace Gardens and - on a clear day - Mount Fuji.

The treatment menu - like the spa's design - has taken inspiration from the purifying journey of Evian's natural mineral water and uses products from Omnisens and Anne Semonin throughout.

MEC Design International Corporation led the design of the Evian Spa, with Thermarium supplying the men's reclining bath and the marble sauna colour therapy.

Other suppliers include Agape (a deep soaking tub within the spa suite); Earthlite (massage beds); and Florieh (head spa beds). FLOS was responsible for the spa's lighting.

Palace Hotel Tokyo executive director and general manager Masaru Watanabe said: "The concept for this spa springs from the mountains.

"The journey of Evian water through the Alps, which leads to its purification and balance, is the same metaphorical journey we're endeavouring to embark upon with our guests."

Adjacent to the spa is a 127sq m (1,367sq ft) fitness facility equipped by Technogym and Life Fitness. A 20m x 5m indoor swimming pool is also among the hotel facilities.

Palace Hotel Tokyo, together with the Evian Spa, is owned and operated by Palace Hotel Co. Ltd.

• Patrick Saussay, founder and CEO of Global Project and Spa Advisory, has been appointed to work with Evian on the international development of the Evian Spa concept for future projects.

In addition to Palace Hotel Tokyo, Evian-branded spas are also located at Shanghai's Three on the Bund in China (SB04/1) and Les Thermes Evian in Évian-les-Baines, France.
