NOT A HOTEL Setouchi is a minimalist villa compound located on Sagishima Island, Hiroshima, Japan, designed by BIG (Bjarke Ingels Group). Few architectural commissions demand the kind of site-specific surrender that island building requires. On Sagishima, a small landmass in the Seto Inland Sea, BIG has delivered its first completed buildings in Japan – three residential pavilions and a communal restaurant that treat the peninsula’s topography less as a constraint and more as a collaborator. The project belongs to NOT A HOTEL, a Tokyo-based fractional ownership venture that pairs world-class architects with fully serviced vacation properties across the country. Here, the partnership produces something closer to land art than conventional hospitality architecture.
Each villa takes its name from the degree of ocean view it commands. “360” crowns the highest hilltop in a ring-shaped plan that wraps the terrain completely, offering uninterrupted sightlines in every direction. “270” occupies a northeastern slope where a central pool – shaped to echo the surrounding sea and islands – organizes the interior life of the house, with living and dining areas effectively floating among water features, fire pits, and a pod sauna. “180” traces the northernmost cliff edge in a gentle arc, its curving footprint following the rock face so that every room opens onto the archipelago. The numerical naming is more than branding. It encodes each structure’s relationship to its specific promontory, a move that recalls Tadao Ando’s site-indexing strategies on nearby Naoshima but with BIG’s characteristic extroversion replacing Ando’s introversion.
Curved rammed earth walls, built with local aggregate, carry the striated warmth of the region’s geology into the interiors. Think of rammed earth as a geological core sample turned vertical – each compressed layer records the color and mineral content of the ground it came from. The technique connects the project to a lineage running from traditional Japanese dobe plastering through Martin Rauch’s contemporary rammed earth innovations in Austria. Glass facades serve as contemporary translations of shoji screens, dissolving the boundary between interior space and the sea while floor layouts reference the proportional logic of tatami mat arrangements. These are not decorative gestures. They establish a tectonic dialogue where Scandinavian openness meets Japanese spatial modulation.
