Kamiyu Onsen: Day-Use Hot Spring Baths & Prices (Nara)

Kamiyu Onsen is a hidden spring welling up in Deyatani, deep in the innermost valleys of Okuyoshino in Totsukawa village. A single inn, Shinyuso, and a large open-air bath built on the riverbed called Kawara-no-yu greet those who come. Set deep in the mountains, the sense of achievement on arriving is part of the charm.

Highlights

True to its name, Kawara-no-yu is a bold open-air bath laid out in stone right beside a clear stream. Soaking in free-flowing spring water while listening to the river run past is a special way to spend time. The sodium bicarbonate water leaves the skin smooth and is nicknamed a beauty bath. Shinyuso has a large open-air source bath for overnight guests, and a day spent with mountain cuisine makes for lasting memories. Facing nothing but the water and nature in remote stillness is the true joy of Kamiyu Onsen.

Enjoying the Seasons

In the fresh greenery of spring and the deep green of summer, the murmur of the river pairs perfectly with the open-air bath. Autumn fills the valley with foliage that colors the tub, and in winter you can bathe while gazing at snow-dressed mountains. When the river runs high the riverbed bath may be unusable, so keep an eye on the weather.

Access and Basic Information

The spring is in Deyatani, Totsukawa village, Yoshino district, Nara. Public transport here is quite limited, so coming by car is realistic, about a fifteen-minute drive from the Totsukawa Onsen bus center. From National Route 168 you climb a road that follows the valley. The bath open to day visitors is Kawara-no-yu, costing around 500 yen for adults, generally open from about 9 a.m. into the late afternoon, with a regular Thursday closure. Note that the inn Shinyuso does not offer day bathing, so day visitors should head for Kawara-no-yu. Open days and whether Kawara-no-yu is available depend on the weather, so it is reassuring to check in advance.

Practical Travel Notes

Because Kawara-no-yu sits right beside the river, it may close for safety in rain or when the water is high, so check the weather and river conditions before setting out. As this is an especially deep-mountain spot even within the Totsukawa hot spring district, it is wise to refuel and shop at a convenience store while still down in the foothills. Pairing it with Tosenji Onsen and Totsukawa Onsen in the same village lets you savor the charm of hidden springs over a two-day trip. As a budget guide, a bath at Kawara-no-yu is affordable at around 500 yen per person.

A Quick Tip

Some stretches of road are narrow, so allow plenty of time when driving. Mobile reception can be poor in places, so saving a map beforehand is wise. Head to Shinyuso if you want to stay over and savor the water at leisure, or to Kawara-no-yu for a day visit, choosing according to your plan.
