A long, wide, double-bay corridor with an open ceiling, *keshō yaneura 化粧屋根裏, that reveals the underside of a roof which has two visible ridge poles, *munagi 棟木. A corridor that connects the east or west separate living quarters, tai-no-ya 対の屋, with the shinden 寝殿, the main building of a shinden style structure, *shinden-zukuri 寝殿造. The futamunerō often served as the master of the house's living quarters, a guest room, and after the beginning of the 13th century, as the drawing room in residences of warriors. In this case it was often called a *dei 出居. Shinden residences in the later periods were on a much smaller scale than those in the Heian period. As a result, the futamunerō was still two bays wide, but it did not extend more than five bays in length. The futamunerō replaced both the tai-no-ya and the connecting corridors, watarirō 渡廊. It was used as a passageway from the middle gate to the main part of the domicile.
