The verdict
A private sauna in Ryogoku themed on mist: löyly, mist and steam in the sauna, a fog above the cold bath and a cold splash for your head.
Press the mist button
A button in the sauna releases the house mist, alongside löyly and a steam generator. The cold head splash pours cold water over you in the middle of a round.
At the cold bath, another button sends a fine fog down from above. Book ahead; a Gold membership at ¥14,000 cuts the price of each later visit.
