Kazoku Yu, also called Shin Amorigawa Onsen, in Kirishima, Kagoshima Prefecture, offers sodium-chloride thermal water at 40°C, an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Shin Amorigawa Onsen; Kazoku Yu' (family bath) in Kokubu district, Kirishima city. 'Amorigawa' (天降川 — heavenly descent river) is the river that flows from the Kirishima volcanic highlands down through Kokubu to Kagoshima Bay — its name literally means 'river descending from heaven.' Hot spring water, like the river, descends from these sacred mountains. The family bath format allows private thermal soaking for those not comfortable with communal bathing.
