Tanegashima's first free-flowing skin-beautifying spring and authentic sauna
Kagoshima Nishinoomote City
Tanegashima Onsen Akaogi-no-Yu is an onsen facility attached to Tanegashima Araki Hotel that also accepts day-trip bathing. The island's first free-flowing natural spring is offered here, known for its skin-beautifying waters that leave the skin smooth. The men's bathing area features an authentic automatic löyly sauna with an Iki stove by Metos and a groundwater-fed cold plunge bath, while the women's bathing area includes a steam sauna wrapped in gentle steam and a well-water cold plunge bath. There is also an outdoor air-relaxation space surrounded by high walls where you can fully enjoy island time and thoroughly totonou (reach a state of perfect relaxation).
TypeNatural Hot Spring
A sodium bicarbonate spring rising from 1,500 m underground is offered in the foot bath and open-air bath as an unheated, free-flowing source. Its cleansing action helps remove old dead skin cells and smoothes the skin, earning it a reputation as a skin-beautifying hot spring.
