latticed shutters
Traditional Japanese and Chinese architectural element: hinged, horizontally-split wooden shutters with latticework, often used on windows or verandas.
On the windows of old townhouses, latticed shutters still remain.
蔀を上げると、庭の景色がよく見える。
When you lift the latticed shutters, you get a good view of the garden.
Standard kanji form for this architectural term.
The kanji 蔀 is composed of 艹 (grass) and 部 (section/part), but the historical derivation of the architectural term is uncertain. The reading しとみ is native Japanese.
