Traditional Japanese homes, featuring earthen walls, wooden beams and thatched roofs, have been used for centuries. Built using local materials, they incorporated clever techniques to keep the interior warm in winter and cool in summer. Our guest, architect Maruya Hiroo, introduces several traditional houses, and explains what life was like for the people who called them home. And in Plus One, Matt Alt sees how the restoration and continued use of old houses is helping to revitalize a small town.
