The Ginzan Onsen Fujiya is a completely wooden hotel 4 storeys high designed by Kengo Kuma in the prefecture of Yamagata, Japan.
The existing façade has been restructured using the centuries-old wood of the original structure, whereas the internal space has been reorganised by inserting an atrium. This element is surrounded by a delicate 'screen' made up of 4 mm thick bamboo panels (Sumushiko).
Behind the bamboo screen, sits an almost-transparent, pale green stained glass surface. The surface has been inserted in the opening that faces the exterior space, filtering natural light and views. First used in the middle ages, the hand-blown glass measures 5mm in thickness. Together with the bamboo lattice, it creates a serene atmosphere that enhances the feeling of healing and relaxation.
