Traditional Japanese architecture uses post-and-lintel structures – vertical posts, connected by horizontal beams.
Rafters are traditionally the only structural member used in Japanese timber framing that are neither horizontal nor vertical.
[1][2] While fixed walls are used, a variety of movable partitions are also used to fill the spaces between the pillars.
They may be free-standing, hung from lintels,[3] or, especially in later buildings, sliding panels[a] which can readily be removed from their grooves.
[6] They are used to modify the view, light, temperature, humidity, and ventilation,[6] and to divide the interior space.
