Shiobara Onsen-kyo

Eleven baths along the Hōki

Local tradition fixes the opening of Shiobara at the Motoyu spring in the Daidō era, around 806 CE, and a written record of organised bathing reaches back beyond a thousand years. What grew out of that single source was not one resort but a chain. Strung along the Hōki river as it cuts west through the southern flank of the Takahara massif, the valley holds eleven separate bath districts — Ōami, Fukuwata, Shiogama, Shionoyu, Hatabori, Monzen, Furumachi, Nakashiobara, Kamishiobara, Shinyu, and Motoyu — together known as the Shiobara Jūichi-yu, the eleven baths of Shiobara. Roughly 150 sources feed them, and each hamlet developed its own water character and its own circle of regulars over the Heian and Edo centuries. The novelist Tayama Katai, writing his 1918 Onsen Meguri, applied the term onsen-kyō (hot-spring resort) to Shiobara, and the word stuck.

A forested gorge with suspension bridges

The setting is a deep, wooded ravine, walled by ridges that rise to roughly a thousand metres on either side. Ryokan sit close to the river, many with rotenburo built straight over the rapids, and a footpath threads the valley between them. Several pedestrian suspension bridges — among them the long Momiji-dani Ōtsuribashi, the Kurenai-no-tsuribashi, and the Nanatsuiwa Tsuribashi — span the Hōki at intervals, and in late October and early November the maples on the slopes turn the whole circuit deep red. The waters across the eleven baths cover an unusual range for one valley: simple alkaline springs at the lower hamlets, sodium-calcium sulfate water in the middle stretch, milky sulfur springs at Shinyu and Motoyu near the head, with iron-bearing and carbonate-tinged waters appearing at individual sources. The overall feel is quieter than the better-known Tochigi resorts to the east, in keeping with the mountain country it sits in.

Beyond the bath

The trailheads for Mount Takahara lie within easy reach for a half- or full-day walk, and the Shiobara valley footpath itself runs about eight kilometres between bridges and small waterfalls. The wider Tochigi food culture is also part of any stop: the prefecture is one of the country's recognised homes of tonkatsu, and Shiobara has its share of long-running cutlet houses for an after-bath meal.
