The Silver Spring of Healing

This Radon-sen No. 1 source plays a key role as one of the "Ginsen" (Silver Springs) that color the history of Arima Onsen, one of Japan's three ancient hot springs. In contrast to the reddish-brown "Kinsen" containing iron, Ginsen is characterized by its clear, smooth feel. The water from this source is said to gently stimulate cells and vitalize the body as it's absorbed through breathing.

Mild Soda-Salt Spring Beneath Kobe Port

This port-town spring is drawn from 1,150 m beneath the First Pier of Shinko, reclaimed land surrounded by the sea on three sides in Kobe Port. Bicarbonate, the soda component, blends with sea-born salt, smoothing the skin while keeping you warm long after bathing. Close to body temperature at 37°C when it emerges, it is a gentle, neutral, pale-yellow water.
