Sennin-buro River Bath; A huge open-air bath

Sennin-buro River Bath is a huge open air hot spring, located in Tanabe, Wakayama Prefecture. It is only accessible in winter. If one digs a hole in the gravel river bed, hot thermal water percolates in, creating an onsen bath. This is a distinctive feature of this hot spring. You can only enter the hot spring in the winter time. In the evenings, you can soak in the hot spring while looking at the stars and listening to the sound of the river. Every Saturday from 8 PM to 10 PM, the  "Yukemuri lantern event" is held.  The bath is lit with lamps which produces a beautiful picture.

The hot spring water is 73 degrees Celsius, but is cooled down by the river water, which is why the temperature is different every day. Depending on weather, admission might be limited, so please check in advance.

This bathing facility is mixed. Please be sure to wear a swimming suit at all times.


1 hour 30 minutes from Nankitanabe IC on Hanwa Expressway. Parking lot is available. Otherwise, get off Kii-Tanabe Station, take the Ryujin bus and get off at Kawayu Onsen bus stop.
