The landscape of the Tokaido main road was different on the streets and in areas where inns and resting facilities were located. Inns in the late Edo Period were mostly two-storied structures and tiled roofs were becoming commonplace. Resting facilities were generally single storied or low-roofed two-storied structures where travelers were not allowed to spend the night. The streets were always lined with pine trees making it easy for travelers to proceed on their journey without getting lost. Signposts were sometimes erected at places where travelers where likely to take the wrong road, such as around inns in areas with numerous streets or at Oiwake (intersections).
