The focus of Japan’s onsen and wellness hospitality has recently expanded to include highly specialized sauna-centric facilities. In Aichi Prefecture, At-in Co., Ltd. launched a crowdfunding campaign for ‘Super Sauna Ichinomiya’, a male-only facility scheduled to open on September 8, 2026. The project aims to transform a former large-scale public bathhouse into a ‘sauna utopia’ featuring expansive outdoor bathing spaces.

Simultaneously, in Gujo City, Gifu Prefecture, R. D. C. Co., Ltd. opened ‘Zen -zen-’, a private, reservation-only immersive sauna facility in the Motofukuro area. This facility utilizes earthbag construction to create a soil dome that provides gentle, radiating heat. The experience is centered on natural elements, including a Finnish sauna stove and a cold plunge bath supplied by continuous natural underground water maintained at 16–18 degrees Celsius.

These developments continue the broader trend of diversifying the onsen portfolio through niche wellness experiences, ranging from traditional regional lodging to specialized thermal and meditative environments.
