Sodium Chloride spring

A sodium chloride spring classified as 'kyoen' (strong-salt) — chloride accounts for some 90% of the anion balance and total dissolved solids reach 27.6 g/kg, approaching ocean salinity. Salty and faintly bitter on the tongue, it leaves a noticeable mineral film on the skin and a long-lasting warmth after the bath.

There is a day-use option. The men's bath includes a mizuburo (cold water bath). There is also a hammam. The rotenburo (outdoor bath) is large and scenic, but the water is plain (although in the hotel's photos, the large baths also clearly have brown water….😶). The mineral water in the small baths for 2-3 people: one is inside, and the other is outside but behind a fence (they said these are kakenagashi, meaning continuously flowing water). The water is brown, odorless, salty, and quite hot (feels like 43°C or higher). The hotel itself has a luxurious and delicious buffet. The location is central. The rooms are well thought out. The staff are lovely)))
