A sodium-chloride strong-salt spring in the Arima tradition — hypertonic, with a dissolved-solids load that exceeds ocean salinity and leaves a noticeable mineral film on the skin after the bath. Neutral pH and a hot wellhead put it firmly in Arima's heat-retaining lineage; a respectable 94 mg/kg of metasilicic acid softens the otherwise mineral-heavy feel.

346. Gekkoen Korokan, Arima Onsen ★★ Stayed overnight with meals included. There was no problem with a double kaiseki for one person, and I liked the food. If you stay overnight at Gekkoen Korokan, you can use the onsen at the neighboring Gekkoen Yugetsusanso without limits, since it is connected by an indoor passage and a separate bridge. There are private baths for ¥2,200, but all of them use tap water, and they warn you about this separately and emphasize it. The room was fairly spacious, but in a Western style. The plans with higaeri meals are listed on the website. 1. Public bath. The bath photos from the internet match. 1.1. Nice open-air bath. There is a decent view of the trees. The water is cloudy brown, temperature 39-40. There is also a round rinsing bath nearby with clear water. 1.2. Inside bath with clear water, temperature 40-41. Easy to breathe. 1.3. Sauna. 2. Private bath with a window. The water is tap water, clear. Temperature 40-41. 3. Indoor private bath with wine, tap water. Temperature 40. If you take it, it is better during the day, because the color looks much more interesting in daylight. Given the total number and level of the baths, it is worth considering staying there to get access to the onsen through the Korokan + Yugetsusanso combo. Very much so. 05.01.2025 06.01.2025
