Shitomi. To open, the top half is hooked up. In this type, the bottom half is lifted out (here, it is leaned up against the closed shitomi alongside). Note hooks, both empty and in use, dangling from eaves.
Shitomi (蔀), also called hajitomi (半蔀) are square-lattice shutters or doors found on older-style Japanese buildings. They are characteristic of the Shinden style,[1][2] and the Heian Period (794-1185).[3] They were used in aristocrats' palaces, and more rarely occur in temple buildings.[3] They were replaced by sliding panels in the Shoin style.[4]
They are usually split and hinged horizontally; when open, the upper shutter was held up at 90 degrees to the wall with hooks, and the lower half could either be lifted out or folded parallel to the upper shutter.[1] This makes it possible to take down the entire wall and just leave the pillars.[3] They are occasionally referenced in modern architecture.[5][6][7]
