okiyane 置屋根

The upper roof erected over storehouses, kura 倉, of the *dozō 土蔵 type. In rural districts where tile was unobtainable, the okiyane provided a weatherproof canopy for the fireproof storehouse. The shallowly pitched lower roof of the storehouse, covered with mud daub *tsuchikabe 土壁, and plaster finish *shikkui 漆喰, formed the base upon which the independent structure of the okiyane was erected. The frame was usually a combination of vertical roof struts koyatsuka 小屋束, purlins *keta 桁, and rafters *taruki 垂木. The roofing material was either thatch *kayabuki 茅葺, or shingles *itabuki 板葺. In this way the vulnerable plaster was protected from rain.
