Hyotan Onsen - A Tattoo-Friendly Hot Spring in Beppu Onsen, Oita

Steam rises from the ground in Kannawa before you reach the entrance. Beppu's most famous hot spring district runs on geothermal heat — it drifts across streets, curls from vents in the pavement — and Hyotan Onsen sits at the center of it, drawing from a 100°C source that's been feeding these baths since 1922.

This is a day-use facility built around variety. Eight types of bathing spread across the grounds: gourd-shaped stone tubs, a row of takiyu waterfalls that pound your shoulders from three meters up, hinoki cypress pools, rock baths, a walking bath, rotenburo under the trees, and steam rooms thick with geothermal vapor. Add a sand bath where heated volcanic sand buries you to the chin, and you have a place designed for a full afternoon, not a quick soak. A restaurant and jigokumushi steam kitchen on site mean you don't have to leave between rounds.

If you're visiting Beppu with tattoos and want the widest range of bathing in one stop — communal pools, sand, steam, waterfalls, outdoor soaking — this is the facility where tattooed guests bathe openly across every area, no covers needed.

• Tattoos Accepted Across All Areas: Recent reviews from both Japanese and international guests confirm tattooed bathers in the communal baths, sand baths, steam rooms, and rotenburo — no covers, no questions.
• Eight Ways to Bathe: Gourd-shaped tubs, takiyu waterfalls, hinoki cypress baths, rock pools, walking bath, rotenburo, steam rooms, and sand baths — more variety under one roof than most onsen towns offer across an entire district.
• Michelin Three-Star Recognition: The only hot spring facility to receive three stars in the Michelin Green Guide — rated "worth a special journey" — for the quality of its source-flowing water and bathing experience.
• Source Water, Undiluted: Every bath runs 100% source-flowing spring water, cooled from 100°C using a proprietary bamboo system rather than mixing in cold water — the mineral content reaches you intact.

The takiyu hit first. Nineteen streams of hot spring water fall from three meters above, driving heat straight through your shoulders and down your spine. The men's side has all nineteen; the women's side has eight, equally forceful. From there the baths fan out: gourd-shaped stone tubs, hinoki cypress pools that smell like fresh wood, a walking bath at knee depth, a cold plunge, and a rotenburo set among trees and stone walls.

The water is mild — clear, nearly odorless, soft enough on the skin that you notice the difference when you towel off. The steam rooms run on raw geothermal vapor, dense and heavy. The sand bath is its own experience: attendants bury you in volcanically heated sand until sweat pools at your temples. Between soaking rounds, the courtyard has a drinking fountain fed by the spring and a jigokumushi kitchen where you steam your own food over geothermal vents.
