Miyagi Sendai City
A healing grove where natural hot spring water from 1,100m underground and innovative saunas invite you in
"Aiko Tenkū no Yu Soyogi no Mori" is a day-use bathing facility in Sendai, Miyagi Prefecture. Its natural hot spring chloride spring, gushing up from 1,100m underground, gently envelops the body, while the open-air bath overlooking Mount Izumigatake offers a liberating moment. The sauna features two types: the "Bon Sauna," where powerful gusts rage through, and the "Zen Sauna," where you can immerse yourself in self-löyly amid silence. In the cold plunge bath using natural underground water, you can cool down cleanly and sharply. The facility also includes a bedrock bath area with light and video effects, a restaurant serving local ingredients, a wide variety of relaxation services, and a rental space where you can play PC games, creating a space that soothes all five senses throughout the day.
