Kasukabe Onsen
TypeNatural Hot Spring
A natural hot spring with a smoky scent, rich in iron, that gushes from 1,500 m underground. In the open-air bath with free-flowing spring water, you can enjoy the highly mineralized 'heat bath' as it is. It has an extremely strong warming effect, and its signature feature is that the warmth lingers even after you get out of the bath. This is the facility's pride and joy, a source spring that lets you enjoy an authentic therapeutic bathing experience even in the middle of the city.
