The front pillars and doors are covered with one small roof and the rear support pillars and support beams are each covered by a separate roof on either side at right angles to the main roof over the front pillars. This type of gate is often used as the outer gate of a masugata. There are two types of Koraimon. The roof of the older style is nearly even with the surrounding walls, while the newer style gate is taller so the roof is up higher than the surrounding walls.
