Yufuin Kenko Onsenkan

Yufuin Kenko Onsenkan sits on Yufuinchō Kawakami in Yufu, Oita, and operates as a straightforward day-use onsen facility rather than a resort spa. The single admission fee covers two distinct areas: a bade zone where swimsuits are required and mixed bathing is allowed, and a traditional hot spring section split into separate men's and women's baths. Sauna and pools round out the facilities, and parking is on site.

General admission runs 930 yen for adults, with a reduced 460 yen rate for high school students and younger visitors, as well as for seniors 65 and over. A separate pricing structure exists for residents of Yufu city. Those arriving without gear can rent a bath towel (220 yen), swimsuit (220 yen) or swim cap (110 yen), or buy a towel, body soap, shampoo, conditioner or makeup remover at the counter; the main bathing hall itself does not stock free amenities like soap, so plan to bring your own or pick these up there.

The facility is open from 10:00 to 21:00 daily, with last entry at 20:30, but it closes on Thursdays (shifting to the following day if a holiday falls on Thursday) and over the New Year period from December 31 to January 2. Walk-ins are accepted and no advance booking is needed, making it a low-key, affordable option for soaking in Yufuin's hot springs without a hotel stay.
