This facility combines a completely private Finnish sauna room and a hotel where people can stay in an apartment style. People can fully enjoy their own private space in the middle of Tokyo. It is about six minutes on foot from Shinjuku Nishiguchi Station on the Toei Oedo Line. There are two types of sauna rooms: a single room (for one person) and a group room (for two persons). The sauna is a “self-Löyly method” that you can enjoy in your favorite style according to your physical condition and mood. “Löyly” is Finnish-style sauna bathing that promotes sweating by pouring water on heated sauna stones to generate steam, which raises the temperature of the room rapidly and stimulates perspiration. The break room is equipped with Bluetooth speakers and other facilities and amenities. It helps you to rejuvenate, or “totonou” in Japanese, at your own pace without worrying about other people’s moods. The theme of the attached hotel is a simple and compact Manhattan style. In addition to apartment-type rooms for long-term stays equipped with kitchenettes and laundry facilities, there are also compact-type rooms that are easy to use for casual trips; therefore, people can choose. Taking only a sauna or just staying at the hotel can be your choice. Refresh your mind and body away from the outside world.
