There will be the Haiden Oratory after you passed the Shinmon gate. This building is single layered curvature and Irimoya style roof. The Irimoya style is that two styles of roof are combined. Upper part of the roof seems to be a triangle because it is made from two slopes, which are put on both sides of a ridge. You will find gables there. Also, lower part of the roof has eaves on all sides, and this construction is called Kiritsuma style. In addition, entire building is vermilion lacquered, but roof is tiled by black lacquered copper.

There are stone steps in the center of front, and double door after the stairs. Other doors are latticed and made to protect inside from storm and sunlight. There are downstairs in the inner Haiden, and passage connects to the Honden main hall through the Karamon gate.

Although, Haiden Oratory is the place, where many people visit, and busy for regular festivals, Yayoi festival and praying, there is no decoration such as sculptures and patterns. It is simple, but strong.

The actual date of construction is not known, but maybe from 1644 to 48.
