Enveloped in mist, lose yourself. The unprecedented, dreamlike pinnacle of “ととのい” woven by three kinds of steam
A new kind of fully private sauna where steam and mist intertwine
【SAUNA霧宙】
In Ryogoku, Sumida, Tokyo—tucked away in a corner of a neighborhood known as the sacred home of sumo—lies “SAUNA霧宙（サウナむちゅう）,” a dreamlike space that makes you forget the everyday.
With the concept “Enveloped in mist, free to be absorbed,” it offers fully private luxury saunas that fuse cutting-edge technology with original, inventive features.
Its hallmark is a unique sauna experience that combines three different kinds of steam: mist, löyly, and a steam generator.
With online reservations and an unmanned check-in system, you can immerse yourself in deep, personal relaxation without interruption.
The two private rooms, uniting design and functionality, are fully equipped—from the sauna room and cold bath to a relaxation area.
In an art-like space where light and mist intertwine, enjoy a special moment that frees both body and mind.

1. Two enchanting private rooms created by mist and light
We offer two rooms with distinct atmospheres to choose from according to your occasion.
•「Mist Room」 (up to 4 people): Pursues deep relaxation that satisfies the five senses. Equipped with a full-flat bed, it leads you into deep totonoi while lying down.
•「Sky Room」 (up to 5 people): An active space to enjoy a floating sensation. Its standout feature is resting in a hammock, letting you experience a new kind of totonoi as if floating in midair.
Both rooms feature carefully designed lighting so the mist looks its most beautiful.

2. One-of-a-kind “totonoi” gimmick 「Kirichu Mist×Cold-Head Splash」
Exclusive services available only at SAUNA霧宙 accelerate your totonoi.
• Kirichu Mist: With a single button, fine mist is generated from the top of the sauna room. The gentle vapor envelops your entire body.
• Cold-Head Splash: Pouring cold water from above your head inside the sauna creates an intense temperature contrast, delivering a refreshing sensation said to equal three sets in just one.
• Mist Totonoi: Mist also descends from above the cold plunge, helping dissipate heat from the head and face while letting you enjoy the pleasure of natural waterfall spray.

3. A luxurious customization experience designed to your liking
In addition to Finnish-style self-löyly, choose from four original aromas to surround yourself with your preferred scent.
The cold plunge allows temperature adjustment by adding ice (for those who want it extra-chilled).
Furthermore, the 「Sky Room」-exclusive 「Steam Sandwich」 sandwiches your whole body between heat rising from your feet and löyly from above, offering the ultimate sense of embrace.
Along with abundant amenities, the drink menu is also extensive, including the sauna favorite 「Oropo」 and detox water.
