Amagase Onsen Yakushi-yu open-air communal bath
天ヶ瀬温泉 共同露天風呂 薬師湯
Amagase Onsen, where steam rises along the Kusu River in Hita, Ōita, is counted with Beppu and Yufuin among the 'three great springs of Bungo'. Its trademark is the communal open-air baths dotted along the riverbed, and Yakushi-yu is one of the most approachable: a single rock tub, mixed bathing, ¥100 dropped into an unattended box. The 75°C simple sulphur spring is diluted to a comfortable temperature, with a faint whiff of sulphur and a view of the spa street across the river. Open 10:00–22:00 daily; wrapping a bath towel is allowed, which makes it easy for first-timers, and it is lit and atmospheric at night. Stroll the town, rebuilt after the 2020 floods, and try the other riverside baths such as Kanda-yu and Ekimae Onsen. About 10 minutes on foot from JR Amagase Station.

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.
