Auberge Uchiko is a Japanese-style auberge located in Ryuoh Park in Uchiko Town, Kita District, Ehime Prefecture, offering a luxurious stay surrounded by historic townscapes and the natural beauty of the four seasons. The accommodation features a Japanese modern space wrapped in locally produced Uchiko cedar and washi paper, with all 5 detached villa-style rooms (Private Villa and Suite Villa) intentionally without TVs or clocks to provide the experience of 'luxury of doing nothing.' The auberge is renowned for its innovative French cuisine, prepared by chefs using locally sourced Uchiko and Ehime ingredients cooked over wood fire. The hot spring is a hypotonic mildly alkaline spring with a pH exceeding 10, characterized by smooth, silky water with a slightly slippery texture, and the luxurious open-air bath with free-flowing source water offers panoramic views of Uchiko Town and seasonal landscapes. Day-use bathing is available, with a large bath featuring locally sourced Iyo blue stone, an open-air bath, a dry sauna (about 92°C), and a cold-water bath (about 15°C), making it a popular destination for sauna enthusiasts.
