Ryujin Onsen

Ryujin Onsen is a hidden, historical hot spring settlement situated in the mountainous heart of the Kii-Hanto Peninsula along the upper reaches of the Hidaka-gawa River, famous for its beautifying mineral waters. 

It is located at the southern entrance of the Ryujin-Koya Skyline highway that links Koyasan and the Kumano area and is a perfect place to stop and relax between these two sacred sites. The Skyline offers wonderful panoramic views of the forested peaks, layer upon layer into the horizon.

Beautifying Hot Spring

Ryujin’s high-quality hot spring waters are clear with a high quantity of sodium bicarbonate and are considered to be the best in Japan. 

The smooth and silky waters are well known for making skin beautiful and are one of Japan’s three famous Bijin-no-yu or “Beautiful Women Hot Spring”.

History

In ancient times, Ryujin Onsen was discovered by Ennogyoja, the founder of Shugendo, a shamanistic religion of mixed originals focused on mountain worship. 

Legend has it that Kobo Daishi, who founded the Shingon esoteric sect of Buddhism and Koyasan, had a divine revelation in his dream from the god of the sea, Nada-ryu-o, which lead him to the spot.

In the Edo era, it was used as a resort area for the Tokugawa ruling family of the Kii-shu domain, their castle being in Wakayama City. At present there are still Japanese inns with names such as “Kamigoten” (Royal Palace), and “Shimogoten” (Lower Lodgings), reminding us of the old Japanese feudal system.
