Kawayu Onsen (Kumano Hongu Onsen-kyo)

Ryujin Onsen in Ryujin Village, Tanabe City — Best Savored in Winter

Tucked in the mountains of Tanabe City, Wakayama Prefecture, Ryujin Village sits along the upper reaches of the Hidaka River. Ryujin Onsen here is known as one of Japan's Three Beauty Hot Springs, alongside Hinokami Onsen in Shimane Prefecture and Kawanaka Onsen in Gunma Prefecture.

In winter, the air in Ryujin is crisp, mountain ridges stand out sharply, and only the sound of the river and the drifting steam of the baths fill the valley. Unlike the coastal areas of Kumano, this is a hot spring town made for a quiet winter trip.

Why It's Called One of Japan's Three Beauty Hot Springs

The waters of Ryujin Onsen are known for their smooth, silky feel on the skin. The baths are said to leave your skin moist and supple after soaking, and they have long been cherished as a "beauty bath." The spring is said to have been discovered about 1,300 years ago, and it has also been passed down as a therapeutic bath associated with the Kishu Domain.

The gentle warmth that soaks into a chilled body feels especially welcome in the cold season.

Tips for Enjoying Winter Bath-Hopping

Repeat Short Soaks and Rests Rather Than One Long Bath

In the cold, it's tempting to stay in the water for a long time. But to avoid getting lightheaded or catching a chill afterward, it's best to soak briefly and take breaks in between. Don't forget to hydrate after your bath, either.

Don't Forget an Outer Layer for "Outdoor Air Bathing"

Nights in the mountain village get cold. To avoid getting chilled when stepping outside in just a yukata, bring something to throw over your shoulders — it will make a big difference.

A One-Night Stay to Savor Ryujin's Winter Hours

Day trips are possible, but winter days are short and mountain driving calls for extra caution. Staying overnight lets you take your time with the mountain village at dusk, the stillness of the night, and the clear morning air.

Preparing for Snow and Icy Roads

Ryujin Village lies in a high-elevation mountain area, and winter temperatures drop even by Wakayama standards. Mountain roads may ice over or accumulate snow, so keep the following in mind.

If you're using public transport, service can be infrequent, so allow extra time for your return.

Easy to Combine with a Kumano Trip

Ryujin Onsen is easily accessible from Shirahama and Tanabe. Adding a mountain hot spring as a rest day after walking the Kumano Kodo, or as a finale to a seaside trip, brings a nice change of pace to your journey.

In Summary

Ryujin Onsen in Ryujin Village, Tanabe City, lives up to its reputation as one of Japan's Three Beauty Hot Springs, with its silky waters and quiet mountain setting. The colder the winter, the more deeply the warmth of the baths sinks in. Plan a comfortable schedule, dress warmly, and enjoy some unhurried onsen time.
