This facility, "Onjuku Itsukiri" (https://itsukiri-onjuku.com/), opening along the white sands of Onjuku Coast overlooking the Pacific Ocean, is a new accommodation facility that expands the philosophy of "Itsukiri," developed in the Satoyama (mountain villages) of Isumi City, Chiba Prefecture, to the "sea." In a new original landscape of "Satoumi" (coastal areas) contrasting with Satoyama, we offer a new stay experience called "Satoumi Retreat," where you can savor the local culture with all five senses through hot springs, saunas, food, and nature.
With an unparalleled location just a 0-minute walk to the sea, all guest rooms are equipped with natural hot springs, private saunas, and cold baths. Furthermore, 8 rooms feature private pools, allowing you to enjoy a special time where the sea, sky, and architecture become one.
"Tourist destinations are created." We value the inheritance of local landscapes, culture, and people's lives to the future, while re-editing "the meaning of staying in that land" and creating new tourism value.
