Japanese traditional architecture, Tsukiagedo

Unlike the Western houses, which were using glass windows since the 17th century, the traditional Japanese houses were built with windows covered with semi-opaque washi paper, which let the light pass through it while being resistant enough to withstand the wind and the rain.

But in some cases, like in this tea-house from Kodaiji, Kyoto, to ventilate the rooms or to enhance the interior lighting, some windows were left uncovered, being protected by large wood-and-paper shutters called tsukiagedo or tsurido. Hinged on the top, the tsukiagedo was fixed open with small poles, giving the house a distinct appearance.
