Private open-air bath in your room
Arima Onsen Hanano (Adults Only)
Rooms with private hot spring bath
from ~$268 / nightView stay →
Most onsen towns have one spring. Arima has two, and they could not look more different.
Kinsen, the "gold spring," is loaded with iron and salt. It comes up clear, then rusts red-brown the moment it meets the air — the colour Arima is famous for. Ginsen, the "silver spring," runs clear: a natural blend of carbonated spring water and radium spring water. Regulars here choose their bath by which water they want that day. Stay at any of the 16 properties below and nobody makes you choose — each one lists both springs in its spring profile, so gold tonight and silver tomorrow morning is a perfectly reasonable plan, in a bath that is yours alone.
Three of them pour their water free-flowing (kakenagashi), straight from the source with no recirculation: Arima Onsen Hanano (Adults Only), Arima Onsen Gekkoen Korokan, Okuno Hosomichi, Hanakoyado, Gekkoen Yugetsusanso, Tocen Goshoboh. Every property page shows the spring profile and how the water is handled, checked against the property's own published sources.
Arima Onsen — about 30 min from Kobe / 1 h from Osaka
Six stays, both springs, a private bath in every one
16 properties, each with a private bath in the room. Every property listed here has a private bath — a reservable private bath or an open-air bath in your own room — so tattoos are a non-issue, and so is privacy.

One honest exception. At Gekkoen Korokan the onsen water is in the room baths — its reservable private baths are plain hot water, and its page says so plainly. At the other five, the private bath is the onsen itself.
