About

Hotel Seikai sits above the beach at Futami Bay, the only inn in the area drawing on a genuine natural hot spring. Its two indoor-outdoor bath halls, Hinode-no-yu and Shinju-no-yu, swap between men's and women's use through the day, and the outdoor side looks straight out over Ise Bay toward the paired rocks of Meoto Iwa. The hotel itself is an older, Showa-era building, plain and lived-in rather than polished, with tatami guest rooms and a big hall built for the group-tour era.
