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.
An inn famous for spring water that turns cobalt blue on certain days. A wide open-air bath with views of Mt. Yufu and silica-rich water that feels like lotion, for ¥800.
A communal bath 5 minutes from Yufuin Station. Drop ¥200 in the offering box by the Yakushi statue and walk in — open 6 am to 10 pm. A slice of everyday Yufuin away from the tourist street.
A long-established inn on the southern rim of the Yufuin basin. Its vast 'Gomusō-no-yu' open-air bath looks straight at Mt. Yufu across the valley. Day-use reception is short (10 am–2 pm), but on weekdays you may have it to yourself.
