Beppu Onsen Hoyoland (Mineral Mud Bath)
別府温泉保養ランド（鉱泥湯）
A cure-oriented inn founded in 1973 in the Myoban area of Beppu, one of the Beppu Hatto. Its draw is a rare natural mineral mud bath - fine mud born only where steam vents, humic clay and mineral springs coincide - which you soak in across the whole body in open tubs. The water flows free from the self-springing source once called Konya Jigoku (a simple acid spring, pH 2.9, 49.7°C): milky acidic water and thick mud baths alike. The mixed open-air mineral mud bath has a partitioned women's section, and women bathe wearing hair caps. Indoors there are a sulfur colloid bath, more mud baths and a steam bath; the underground mineral mud chamber is so concentrated that elementary-age children may not enter. Day bathing runs 9:00-20:00 (last entry 19:00; indoor mud and steam baths until 19:30) at 1,500 yen for adults. There are no washing stations, only mud-rinsing showers - authentically rustic. Get off at the Nayajigoku-mae bus stop from Beppu Station; free parking, open year-round.

More in this area
Takegawara Onsen
Founded in 1879, with its 1938 wooden building and curved gable, Takegawara is the symbol of Beppu Onsen. A regular bath costs ¥300 — a deep, hot pool down a flight of steps. The famous sand bath has you buried in warm sand by staff while wearing a yukata. Bring your own soap and shampoo.
Hyotan Onsen
A large complex where you can try Kannawa's specialties — waterfall bath, sand bath and steam bath — in one place. It once earned three Michelin stars and is used to overseas guests. Many private family baths; tattooed visitors are directed to these. A restaurant serves hell-steamed dishes. Open until 1 am.
Shitan-yu at Lake Kinrin
A thatched communal bath on the shore of Lake Kinrin. Unstaffed — drop ¥300 in the box at the door. Changing area and bath share one room; an indoor pool and a half-open pool facing the lake, and it is mixed bathing with clear water and little screening, so it's a challenge for women. Right in busy central Yufuin, but quiet at the 10 am opening.
