Insider tip — 'Haribara Shioyu Onsen' (針原塩湯 — needle-field salt spring) in Izumi, northern Kagoshima. 'Shioyu' (塩湯) explicitly names the sodium-chloride character of this spring — saltwater thermal baths are prized in Japanese onsen culture for their warming, skin-softening properties and cardiovascular benefits. Located in the inland Haribara district, away from the coastal crane fields, this is a quieter neighbourhood bath serving rural Izumi.
