Sunamushi Kaikan Saraku
The municipal facility for Ibusuki's famous natural sand bath. Change into a rental yukata, walk down to the beach, and staff bury you in hot sand for about ten minutes; afterwards rinse off in the indoor onsen. At high tide the sand baths move under a roof. ¥1,500 includes the yukata; bring or buy a towel. 20 minutes on foot or 5 by bus from Ibusuki Station.

A vast garden bath hall fed by 14 sources at 1,400 litres a minute, with four water types — sulfur, alum, saline and iron — in one place. The central pool is mixed-gender (women-only hours; bathing garments allowed).
Nigatsuden Onsen Tonosama-yu
A public bath from the early Shōwa era beside the ruins of the Shimazu lords' private bathhouse. The Shimazu crest decorates the tub; the salty water runs hot and free-flowing. Free drinking spring too — a local follow-up to the sand bath.
