The main hall is a Tendai Sect style building rebuilt in 1363 with the Gejin (outer place of worship for public people), which has a wooden-floor, separated from the Naijin (inner sanctum), which has Shihanjiki Doma (squared masonry jointed dirt floor) on the lower level, by wooden lattice shutters.
本堂は、外陣を板敷きとし、蔀戸で仕切られた内陣を一段低い四半敷き土間とする天台式建築で貞治2年（1363年）の再建である。
