Itamuro Bettei

A retreat inn in Itamuro, on the Nasushiobara side of the Nasu mountains, built around toji (湯治, long-stay soaking) rather than sightseeing. The spring water is on the mild, lukewarm side. The sauna has a cold plunge deep enough to put your head under, plus a second one in cypress. Guests also mention bodywork treatments and meditation, and incense greets you at the door. The staff arrange a pick-up from Nasushiobara station by reservation. The feel is calm and unhurried, with the quiet of the woods around it, and people come mainly to rest.
