Also kuginuki 釘貫. A roofless gate found at imperial tombs, mansions, and government check points. When the gate has two penetrating tie beams, the lower one is called shita-no-nuki 下の貫, and forms the lintel against which the gates close. The upper tie beam is called ue-no-nuki 上の貫, and is as long as the lower one but is set approximately the diameter of one pillar above the lower tie beam. Sometimes there is only one penetrating tie beam with fences attached to the outer side of each post. In this case there are no doors, and the gate has some resemblance to a Shinto gate *torii 鳥居. When the gate has doors, they resemble those of the doctor's gate *yakuimon 薬医門. The upper part of the doors, slightly greater than half the overall height, has a vertical lattice taterenji 竪連子, set at regular intervals. Characteristically, the lower area has x-shaped boards *tasuki 襷 against a solid wood backing of horizontal boards. The two doors can be bolted when closed.
