Classification

Sodium Chloride spring

The Shikei source of Arima Onsen — an iron-rich sodium chloride strong-salt spring. At 44 g/kg of dissolved solids it far exceeds ocean salinity, leaving a thick mineral film on the skin and ranking as a hypertonic water. It carries 67 mg/kg of iron and oxidizes reddish-brown on contact with air, which is the origin of the 'Kinsen' (golden spring) name: colorless at the wellhead, it turns tea-brown as it stands. At 98.6 °C it is among Japan's hottest natural sources, strongly salty and exceptionally heat-retaining.

353. Takayamaso Hanano, Arima Onsen Visited for higaeri for 1650 yen (listed as 11:30 to 15:00). You need to book on their website in advance, and the staff was very thorough about checking my online reservation. Whether you can walk in without a booking — I didn't ask. Inside: a bath with cloudy orange water, temperature around 41. Breathing is excellent. Outside on a small balcony: a bath with clear water, temperature around 41. No proper view. A basic place for Arima Onsen — fine to skip.
