A small 16-room ryokan in Akiu Onsen that runs its two main baths on a gender-rotation schedule. Rairai-no-yu (磊々の湯) pairs an indoor bath with an open-air section where the view shifts with the seasons, cherry blossoms in spring and snow in winter. Sato-no-yu (里の湯) is indoor only, with spring water flowing straight from the source without filtration or recirculation. A private cypress barrel bath is available for overnight guests. The inn operated for generations as Satoya Ryokan (佐藤屋旅館) before rebranding as Soraichi (曽良一).
