Onono Komachi
Hot Spring of Beautiful Women
The Legend.
The Ono from Onogawa Onsen was taken from the name of a Heian Period tanka poet, Ono no Komachi, who is famous in Japan as a symbol of a beautiful woman. Legend says that in 834, Komachi was on her way from Kyoto to visit her dear father, when she fell ill and stopped to bathe at Onogawa Onsen. It is said that she not only made a full recovery, but also became a woman of unsurpassed beauty due to the power of the healing waters. Other distinguished visitors who loved to bathe in the hot springs of Onogawa were Date Masamune the eldest son of Date Terumune, and Uesugi Yõzan.

The hot spring water is 100% natural and flowing.
The hot spring water in the main building is 100% natural flowing water so it is never reheated or re-used. Most inns used to add cold water, due to the high temperature (80.3℃) at the source of the spring. However, in 2008 the Onogawa Onsen association successfully drilled a new low temperature spring source, and so currently the high and low temperature spring waters are combined to create the perfect temperature for bathing.

A special trait of the spring water at Onogawa Onsen is that when the water is exposed to the air a white mineral deposit in the shape of a flower appears. Sometimes these flowers can be seen in the bath tub, sometimes they float in the water, please understand this is a sign of a natural spring.
Benefits of Onogawa Onsen
