The bath of the Satsuma lords
Tonosama-yu (“the lord’s bath”) stands where the Shimazu clan of Satsuma kept a hot-spring villa. In 1831 the 27th head, Shimazu Narioki, moved his Nagai Onsen lodge here, and the stone tub, paving and tiles used by successive lords still survive behind today’s bathhouse as a city-designated historic site. The present bath, opened in the early Showa era, is a plain public bathhouse where 52 °C+ chloride water flows freely into tubs carved with the Shimazu cross-in-circle crest. At the free drinking fountain by the entrance you can sip — or bottle — the bittern-flavoured water.
Tips & cautions
- Closed Fridays (open if a holiday, Obon or New Year). Some sites say 7–21, but official hours are 7:00–20:30 (last entry 20:00).
- The small source tub is scalding; use the main tub, itself a hot 43–44 °C.
- No lockers — leave valuables behind. Toiletries provided, towels sold, so you can come empty-handed.
- The lord’s-bath ruins behind can be viewed free; ask at reception.
- Good for rinsing off after an Ibusuki sand bath. Nearest station is Nigatsuden, one stop before Ibusuki.
