Located in a region with a long onsen tradition tied to the mountains and volcanic geology of the Kanto interior, the facility draws on naturally occurring saline waters known for warming the body deeply and retaining heat long after bathing — a quality the Japanese call 'nidan nuke' (warming through to the second layer). The welcoming, unpretentious atmosphere of Rakurakuen makes it a beloved neighborhood institution for local residents as well as a discovery for travelers exploring the thermal culture of inland Tochigi.
