Yakushi Onsen is one of the oldest hot-spring sento in Kagoshima, close to a hundred years old and renovated in May 2023. Spring water flows straight from the source into the baths. The men's sauna has sauna stones and aroma-water löyly, and there is a cold bath, electric bath and jacuzzi, with breezes from the neighbouring park. Open 6:00 to 23:00.
