The spa is a rare, decadent treat in Tokyo’s hotel Chinzanso and features natural hot springs, a large swimming pool with a retractable roof and top-tier products by well-known brands. Treatment rooms are of a uniquely Japanese design with a view of the hotel’s gardens. Unique deluxe treatments such as the Oriental Scalp service, which relieves tension in the scalp, neck and shoulders, work to leave you refreshed and relaxed. Be sure to try the steaming Japanese onsen bath, which has fresh water delivered from the natural springs. The water is heated to the correct temperature and poured into a cavernous wooden spa pool. The Healing Hot Stone Massage is administered with Aromatherapy Associates essential oils that permeate the room and set the mood for a deeply relaxing spa session.
