Arima Onsen — hot springs by indication | Compare & book 11 inns

The Uwanari Gensen is a primary source for Arima Onsen's famous "Kinsen" (Golden Spring). Its name, meaning "jealousy spring," comes from a legend that the water would gush violently with envy whenever a beautiful woman passed by. [3, 6, 7] Once an intermittent spring, it is now drilled and its waters are distributed to many establishments in Arima via other sources like the Gosho Sengen. [3, 6, 7] Rich in iron and salt, this spring is known for its characteristic reddish-brown color upon oxidation and its ability to warm the body to its core.

The Atagoyama Sengen, gushing forth in Arima Onsen—one of Japan's three ancient hot springs—is a prime example of the "Kinsen" (gold spring), which turns a vivid reddish-brown upon contact with air. Its history is deep, having long supported the therapeutic bathing culture of Arima. The water from this source, rich in salt and iron, offers a powerful warmth that heats the body to its core. Steeping in this bath envelops you in a warmth that feels infused with the earth's blessings, a sensation that lingers long after you emerge.

The Ryusenkaku Private Spring is pumped from a drilled well in Utsugidani, on the hillside of Arima Onsen, one of Japan's three oldest spa towns. It rises a pale yellowish brown, then its abundant iron oxidizes in the air and steeps the bath in Arima's signature rusty red. A brine about half as salty as seawater wraps the skin, and the warmth lingers long after bathing, suited to anyone wanting slow, deep warmth on chilly days.

Its high salt concentration envelops the skin, providing long-lasting warmth after bathing.
