A signature large public bath at Naraya, set within a beautiful heavy timber building infused with history. It was named after the story of Okumigage no Yu, from which Kusatsu hot spring water was drawn and presented to the Tokugawa shoguns in the Edo period. Carefully temperature-controlled through the traditional skill of a Yumori, it allows guests to enjoy Shirahata Source, astonishingly mellow and gently softened, as free-flowing natural hot spring water. The high ceiling and the wooden warmth rising through the steam create a deeply atmospheric bath.

A spacious large public bath with a gentle, serene Japanese atmosphere, featuring both an expansive indoor bath and an open-air bath surrounded by greenery. Shirahata Source, drawn directly from Yubatake, is rested by a Yumori and turned into a softly cloudy bath with an exceptionally gentle, soothing feel, then served as free-flowing natural hot spring water. The open-air bath is appealing for the chance to relax while feeling the trees of the garden and Kusatsu's crystal-clear air, and to fully savor the rich, strongly acidic power of Kusatsu's original hot spring, a different kind of experience from weakly alkaline, beauty-enhancing waters.

Three private baths with distinct atmospheres: Hi, Fu, and Mi. In these modern private tubs accented with Shigaraki ware and cypress, guests can exclusively enjoy Shirahata Source, expertly prepared to an exquisite mellowness by the craftsman Yumori, as 100% natural flowing hot spring water. Ideal for couples, families, or anyone seeking a private bathing experience where they can quietly and fully appreciate an exceptional beauty bath without worrying about others around them.
