Classification

Sodium Bicarbonate spring

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 jūsō-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.

229. Hotel New Arao, Naruko Onsen Visited on higaeri for 3 stickers on the local tegate (listed from 10:00 to 21:00). Almost missed the rotenburo behind a door - luckily an old guy in the changing room tipped me off. Indoor bath with clear water, temperature 41-42. Breathing inside is fine. Outdoor bath with clear water, temperature 40. There's an entrance from both the indoor bath and the changing room, but in the evening you might not realize it and miss this bath. Wide higaeri time slot; in the evening it makes sense to stop by if you're in the area.
