(10:00 ) Arrived Hoheikyo onsen Once you’re fitted with a mountain bike, helmet and gloves, you’ll hear safety precautions and get basic instructions for riding. Then follow your guide on an easy, 1.5-hour ride along a mostly paved road, starting from the upper Toyohira River, whose waters swell from mountain snowmelt into the Jozankei valley. Enjoy views above the river canyon and cross a suspension bridge, departing for Jozankei. It’s a steep, downhill ride to this traditional onsen town, which dates back to 1866 when an ascetic monk opened the spa upon discovering its healing waters. Amid forested banks along the bountiful Toyohira River, watch steam rise up from every angle. Stop to enjoy snacks like onsen manju, a bun stuffed with azuki-bean paste, before departing via a steep uphill route.

(11:40) Return to Hoheikyo onsen, curry lunch and onsen Your 6-mile (10-km) route ends at this natural hot spring, which was ranked as one of the best hot spring day trips by TripAdvisor. Settle into mineral baths indoors or choose from three large outdoor pools, where you’ll have panoramic views of the mountains as you relax against the stones during a 1-hour soak. Hoheikyo is one of Japan's only onsen facilities to use 100-percent pure waters; the pools are fed by continuously flowing hot springs poured directly into the baths from the ground. Afterwards, sate your appetite with a lunch of authentic naan bread and Indian curry — Jozankei’s most popular food — at the on-site restaurant.
