Celebrate the legacy of Jozankei’s founder at this scenic park, where visitors can soak in natural mineral waters and enjoy making their own onsen eggs.

Located at the foot of Tsukimibashi Bridge in the heart of the hot spring district, Jozankei Gensen Park recreates the pristine landscape once seen by Miizumi Jozan, the monk who founded the onsen. As you enter the park, Miizumi Falls cascades over rocks, while a gentle sulfur scent rises in soft clouds of steam.

At the center of the park is a sheltered foot bath (ashiyu) fed directly by a high‑temperature sodium chloride spring exceeding 80°C. Dipping your feet into the mineral‑rich waters, a comforting warmth spreads through your body, easing travel fatigue. The scenery changes with the seasons: in spring, about 400 colorful koinobori (carp streamers) fill the sky, while autumn paints the valley in vivid red and gold foliage.

For a distinctive local experience, stop by Ontama no Yu, a hot spring pool for making onsen tamago. Simply place raw eggs (available at the nearby souvenir shop) into a net and lower them into the steaming water. As you wait 15–20 minutes, enjoy the murmur of the Toyohira River and birdsong drifting through the air. The result is a perfectly cooked egg with a silky white and rich, creamy yolk—an unforgettable taste of Jozankei’s geothermal bounty.
