A small wooden gate used as the entrance to the inner tea garden. A door called tsunodo, made of horizontal boards held with split bamboo verticals, is attached with hinges to swing between two posts embedded in the ground. The door is positioned midway along the length of the posts, leaving openings at the top and bottom. Saru is a local term for "hinge" in the Osaka area, hence the name sarudo (hinged door).
