A sodium-bicarbonate blended spring (a mix of the local 'tansan-sen' and 'kuroyu' sources). Weakly alkaline at pH 8.52 with a soft skin feel, in the juso-sen (soda-water) tradition. Hot at 61.7 °C at the wellhead, and still carrying 705.8 mg/kg of free CO₂ — the carbonated note the source name promises.

About

Hotel New Arao is a plain, no-frills ryokan in the Akayu part of Naruko onsen, with a straightforward indoor bath called Goten no Yu (御殿の湯) and an open-air bath. The spring water is kept flowing fresh in the kakenagashi (掛け流し) style, and bathers describe it as soft and slightly silky on the skin, with a faint earthy, peat-like scent. Day-use bathing is offered. The name Goten no Yu points to an older history: the site says local feudal lords used to come here to bathe, and traces the bath back some 400 years.

229. Hotel New Arao, Naruko Onsen, Miyagi ★ I went for a day trip using 3 stamps on the local tegata (listed as 10:00 to 21:00). I almost missed the rotenburo behind the door, luckily an old man in the changing room pointed it out. Indoor bath with clear water, temperature 41-42. It was fine to breathe inside. Outdoor bath with clear water, temperature 40. There is an entrance from the indoor bath and the changing room, but in the evening it can be easy to miss and walk past this bath. Wide day-trip time slot, in the evening it makes sense to stop by if you are nearby. 06.11.2024
